The treatment in auto industry of Css" Type=text/css Rel=stylesheet> is all production domains in most typical, stem from the requirement to batch, the car makes a lot of flow is medium improvement work to be being abided by " in order to measure score a success " principle. Why is this namely in car treatment order those who make cutting tool to use mix almost standard cutting tool is euqally common, and reside backseat to treatment asks flexibly to be retreated. Machine the slashing requirement of metre to shortening, even if be time of a few seconds,save, it is one of primary motivation that drive a car to machine craft to be improved continuously, also be this kind is opposite shorten the indefatigable pursuit of handling time, make special cutting tool is optimized in the abidance of car treatment craft decisive place is had in the process. In the developmental process that machines craft in the car, tool manufacturer is come from the pressure at car manufacturer ceaselessly, every cross a paragraph of period to be rolled out to compare existing product by the requirement more the solution of actor. Now, the standard cutting tool that can satisfy same kind to machine is being come out by ceaseless development, the share that and the place in application is machined in the car holds is larger and larger, this has been an increasingly clear trend. Use standard cutting tool morely to be able to reduce manufacturing cost, delivery dependability also can get better safeguard. The article will be emphasized 3 cutting use a field under the introduction, from which we will see newest cutting tool not only the requirement that satisfied automobile manufacturing industry to machine efficiency to rising, and assured to machine safe danger. Turning: Treatment of the turning in the treatment of car spare parts is used extensive. In turning treatment, the axis of steeliness kind and dish the condition that is in all sorts of differring plays kind of part have rough machining and precision work. The requirement to spare parts quality also is to have each different, but the requirement to machining metre is the most important forever. In traditional treatment procedure, to assure the requirement of workpiece surface surface roughness, the feed of cutting tool is restricted, cannot shorten further handling time. Milling: The milling of cast-iron spare parts machines a domain in car spare parts very common. In this domain, the contact of cylinder body and housing and sealing surface need to undertake milling. In traditional treatment procedure, the parks machine and cutting tool unreliability of the machine tool often reduced treatment efficiency, mix in rough machining especially semifinishing machining working procedure. Screw cutting: Thread machining is very tall to the requirement of quality. Once thread machining will out of tolerance, production must stop. Thread machining has very firm demand to the cutting blade appearance of thread tool, hold the exact fixed position of cutting blade especially. In the past, the fixed position of whorl razor blade inside bit chamfer stability is not tall it is the element that limitation improves manufacturing efficiency. In undertaking with new generation cutting tool turning is machined in turning, the razor blade that repair light (of Wiper) use can saying was to change " cutting is basic and mensurable " . The tendency of radius of point of a knife of traditional turning cutting tool generates the Dao Wen of scallop form in workpiece surface. The sectional height of the size of cutting tool feed and radius of point of a knife and grain of scallop form knife has immediate concern, decided the exterior quality of turning. The horizontal blade strickle of the razor blade that repair light the coping of the grain of scallop form knife that makes by point of a knife. In turning Xiu Guang's concept needs ceaseless development, can damage treatment face figure and generation in order to avoid to pass great cutting power through reducing Xiu Guangren's length. At the same time bit needs control to cut bits, can hold clip directly like common razor blade. The purpose that the razor blade that repair light develops at first is the appearance maintains when turning double what groovy razor blade raises feed rate while surface roughness is changeless, perhaps maintain feed to lead changeless condition to fall, raise workpiece surface surface roughness double original. Apparent, between these two possibility, can establish the different combination that feed and exterior surface roughness improve, of the efficiency of production of spare parts turning that brings from this rise quite considerable. The principle of technology of the blade that repair light is to be based on circle of big point of a knife horny radius by a series of minor round role radius is planned to close and become. Have radius of a circular arc to the point of a knife of blade of cutting of groovy razor blade. because of such, the razor blade that repair light must accord with the standard of groovy ISO razor blade, it has measure of radius of circular arc of point of a knife of a name, in all sorts of treatment application, dimension of radius of this circular arc is identical. In addition, the razor blade that repair light must be installed easily place and use, need not undertake in process designing and respect of compensation of radius of point of a knife any alter greatly. The first bit repairing light that is used at turning was rolled out above all 1997 by Shanteweikekeleman. This razor blade used the bit chamfer form that is used at rough machining, in order to assure the intensity of point of a knife. At the same time this razor blade has enough long Xiu Guangren, so that use taller feed. The osculatory length of cutting point and workpiece must use form of proper chamfer of the chamfer that break bits to have a balance, in order to achieve smooth cutting and inferior cutting power. Next, type of new the razor blade that repair light is for finish machining development, the limitation that measures to cutting is more rigid. On the foundation of bit chamfer form that machines in medium type, this kind of razor blade has sharper cutting blade and bigger before horn, in tall feed ratio requirement plays enough on the safe side. Two generation repairs smooth razor blade (the workpiece surface surface roughness that WM and WF) have likeness forms character, but both chamfer form is different, to cutting tool life influence character also differs. Compare with the photograph of groovy razor blade that is the same as norms, the cutting strength that generation builds smooth razor blade rose only merely about 5% , this imply is only below the situation that does not stabilize extremely, ability can be repaired the negative effect of form of smooth blade chamfer, for example the turning of long and thin axis, even if use groovy bit, and according to recommend cutting parameter to also want special caution. The big feed rate of the razor blade that repair light can rise stabilization to certain working procedure, can overcome oscillatory trend through choosing smaller point of a knife. Accompany Xiu Guang to bit is applied extensively and survey smooth estimate to exterior quality, the razor blade that repair light can cause oscillatory impression be changed subsequently. The shining surface photograph that produces with groovy point of a knife is compared, the exterior with dark hair of the surface after the turning that repair light becomes contact with photograph of fast face quality. Radius of bigger the point of a knife that repair light can be obtained in turning working procedure beat plain the stability of Bo Changman meaning, the razor blade of first selection finish machining of the common turning that also makes Wiper chamfer form makes all sorts of workpiece material. The razor blade that repair light still has another important effectiveness in turning: Bit can be improved in a lot of working procedure. Because design of Wiper chamfer form leads next having for low feed,partial reason is good the smooth property that break bits is had below function of the control that cut bits and tall feed rate, discharging bits to control in all sorts of application limits so is best. Recently, the bit repairing light that is used at turning needs new development again, it is especially in auto industry. Partial reason is in high feed rate Qing Dynasty condition falls, generation repairs the exterior mass that smooth razor blade builds to have insufficient place. The nominal radius be identical that increases sword of the cutting that repair light the to exterior quality requirement in production. Work to research and development however and character, its are challenged is tall feed rate the actual length that needs Xiu Guangren is restricted. Nowadays, the technology of new generation Xiu Guangren that passes elaborate design is right radius of ground general name and the amount that plan to add up to radius and size photograph combination, the round glide that this combination assured to the accurate result that repair light and Xiu Guangren are the same as part of blade of the others cutting is crossed. The crucial place of structure of new the blade that repair light is the perfect combination of cutting chamfer form and form of the chamfer that break bits, achieve first-rate cutting result thereby. New generation repairs smooth blade technology to must raise workpiece surface surface roughness, feed rate should be equal at least present level. Any oscillatory hasten certainly will that generate by the new razor blade that repair light are needed repair smooth razor blade under generation. Compile the result that smooth razor blade develops newly, created WMX of new form of chamfer of the blade that repair light. WMX of new form of chamfer of the blade that repair light shows the admirable cutting result that reduces oscillatory liability, the noise that can pass the generation in listening treatment is discovered on the level, the cuts bits figure that also can produce from inside treatment observes. The applied domain with the more comprehensive than having look of standard razor blade that new generation repairs a lot of turning working procedure in WMX of form of smooth blade chamfer and original Xiu Guang razor blade or auto industry to use, covered the applied range of original razor blade at the same time. Use older feed rate to be able to develop the latent capacity that increases manufacturing efficiency -- can shorten the handling time of 30% . If use workpiece surface surface roughness to regard as,change the standard of bit, because edge wears away,get clear improvement, new generation repaired WMX of form of smooth blade chamfer to prolong cutting tool life. The new razor blade that repair light accords with the basic form of ISO standard razor blade, install easily place and use. As the original intention of development, raise the level of exterior surface roughness that processes work, bit has shown new bit WMX to acquire better exterior quality below rate of the biggest feed (Ra0.

8) . When a bit low feed is led, WMX can be generated under Ra0.

The exterior surface roughness of 5. Already some generation repairs smooth razor blade (the compensatory chamfer form that WM and WF) will continue serve as WMX exists. WM chamfer form contains a solid cutting blade, when undertaking interrupted cutting to the spare parts, it is more the solution of on the safe side; WF suits finish machining, cut for example deep be less than 0.

When 5mm, or when needing sharper cutting blade and the control that discharge bits is improved in finish machining when. Purpose of design of the blade that repair light and treatment effect depend on cutting blade whether as parallel as feed direction. In certain cutting application, the razor blade that repair light has slight drawback, need makes process designing adjust. When the spare parts has the taper that is more than 5 ° , blade of cutting of the blade that repair light still can undertake cutting, but do not have the outstanding effect that repair light however. To acquire same exterior quality, feed rate must be moved low be worth to the commendation of razor blade of radius of groovy point of a knife. Same, when the treatment that return a vehicle, blade of cutting of the blade that repair light cannot sufficient penetration of a cutting tool, because this feed is led,must lead those who reduce razor blade of radius of groovy point of a knife to recommend a value from the tall feed that repairs Guang Ren. As these fluctuant feed rate hand moves those who lose a person to replace a method, at present software of a process designing can support above application. Major turning treatment is outside round turning and end panel turning, this imply repairs smooth razor blade to be able to shorten significantly cutting time, raise exterior quality and improvement platoon bits and increase security through solid cutting blade. Evaluate the turning working procedure of at hand, see the possibility that uses technology of the blade that repair light, optimize craft with technology of the blade that repair light next, can gain a large number of benefit. In common turning working procedure, on identical knife handle, groovy bit commutation becomes the razor blade that repair light to be able to be in keep outstanding, consistent exterior quality while, shorten directly handling time. New generation repaired WMX of smooth razor blade to develop Xiu Guangren technology truly, ask to do not have special limitation to tall stability at the same time, have the smooth effect breaking bits when Gao Jin gives, it is first selection and all-purpose solution. Milling -- arrive from rough machining finish machining is cast-iron milling is engine and housing kind the substantial that the spare parts makes. In starting a mechanism to build, correct geometrical figure, good appearance is bright and clean degree and 0 reject are absolutely and main goal. Face the cost pressure that increases increasingly however, they are dim and blank. To satisfy afore-mentioned all requirements, need reliable and efficient cutting tool and solution, for example cylinder body and the thick mill that the crock builds each plane and mill of essence of life. To casting factory or other one class cent includes business for, rough machining is the one part that semifinished product machines normally, metallic purify rate is the mainest factor. Finish machining assembled all requirements to efficient, high reliability and high quality, the state that has the process that challenges a gender very much among them is the face milling of combustion face, it often completes the final process that cylinder body appearance machines. In auto industry, cast-iron it is the workpiece data that is used extensively. Grey mouth is cast-iron still take main place, press weight plan, it is nodular cast iron and other sort cast-iron multiple. Recently, the ceaseless development help of material and production expanded squirm Chinese ink is cast-iron (nodular cast iron of CGI) , temper (ADI) and of a series of alloy cast iron use, increased the scope of cast-iron treatment material. Cast-iron cylinder bushing can be combined with aluminium alloy cylinder body, bimetallic makes milling treatment becomes more difficult. Machine the manufacturing efficiency of craft and dependability to rise, a series of cast-iron milling solutions had been rolled out recently. Full early of coke of gram of hill spy dimension is banner rolled out the car that is used at transfer matic special milling cutter and the cast-iron milling in building cap type milling cutter to have mass production. Recently, more and more flexible machining center uses line or only station to machine small lot cast-iron spare parts and car spare parts, mean the milling cutter diameter of 80% to be inside limits of 63 ～ 160mm namely. This mirrorred present cast-iron milling form with each passing day each different, have the small lot on small-sized machining center, light-duty treatment already, the transfer matic in having mass production again go up or the rough machining on heavy-duty machining center and finish machining. Use newly in the process of thick mill and cutting tool of half essence mill in development, damaged of force of the range that wants achieved goal to include cutting tool feed, cutting, workpiece, burr is formed, the improvement of the respect such as exterior quality and noise size. Improving is from what raise tool cutting edge angle 65 ° to begin from groovy 45 ° , this was brought for example milling cutter has lighter cut, can more the good point that approachs the respect such as clamping apparatus treatment. But, largish tool cutting edge angle increased the current of edge of collapse of the workpiece when cutting tool is cut, because structure of the flake graphite in great radial cutting power and cast-iron material produces the account of effect,this is. In fact, change cutting tool decision criteria often must be installed according to the limit of workpiece collapse edge. Accordingly, burst apart to answer what big tool cutting edge angle may bring effect, had designed the bit chamfer form of new 65 ° cutting tool, form of this kind of chamfer can make cutting tool seedling and when giving cutting more advantageous. In addition, the new chamfer form on 8 cutting blade also makes cutting force more the face of the fixed position that prop up of front razor blade. At the same time form of chamfer of partial razor blade forms 8 before become a useful person of the entity that cut bits, they are with first-rate means fixed position on two faces of the razor blade that prop up. Although Nextpage is cast-iron force of the cutting in treatment is smaller, but because force of the cutting when big interface milling distributings,often be in as far as possible large area go up and by high frequency enlarge, so the cutting tool when cast-iron cutting and razor blade are propped up goodly become crucial. The bit chamfer of 65 ° razor blade is having good radial and axial to sustain a scale, outspread all the time the cutting blade to bit, this makes bit can answer burden cutting and resistance to be out of shape, because this cutting tool is during very long service life,have high cutting security. To CoroMill 365 of milling cutter of this kind of new-style and cast-iron face, cutter hub of face milling cutter has exceed big cutting tool to sustain a scale, make milling cutter can obtain the biggest flange to prop up from machine tool main shaft, increased stability. Razor blade of use bolt clamp makes cutting tool processing becomes convenient, cutter hub of close to exceeding pitch uses means of wedge piece clamp. Cooling fluid is the inevitable component of cast-iron cutting, cutter hub of new face milling cutter has perforative cooling fluid channel, refrigerative fluid can arrive directly at every razor blade, in order to assure the biggest cooling effect. Improving feed rate and exterior quality is the character with indispensible cutting tool, the axial that these character ask to exceed blade of cutting of close pitch, razor blade installs precision and Xiu Guang razor blade. Providing tall cutting security while, still need to satisfy these function requirements that raise ceaselessly, this has been in will already the collect of concept of milling cutting tool of test and verify is able to come true successfully on the development of the new-style cutting cutting tool of a suit. Now, have can change the range of products of CoroMill face milling cutter that the knife places is cast-iron with aluminium cylinder body, crock is built and housing offerred semifinishing machining, finish machining and rough machining solution. When cutting tool pitch, precision, clip is held and dependability is critical factor when, clip type milling cutter has obtained the knife that is based on so mature like CoroMill 245 and Contury concept to admit extensively. The knife is the fixed position of clip design and razor blade, adjustable can mix to processability with locking operation function forms notable difference. Mix in the standard order make cutter hub go up clip of use standard knife can offer more effective tine to count -- it is crucial that this produces efficiency and exterior quality to rising. The control of position of axial of every knife clip decided the consistency of exterior quality and cutter hub, ensure any use standards that replace cutter hub or sister cutter hub. Accordingly, the position with firm clip of the knife on cutter hub is restricted and stability and look of good thick harmonic fine tuning are united in wedlock, it is the foundation of cutting tool function. Good design precision, dinky and the tooth form interface that places with the knife, jumpy bit fixed position and photograph of technology of the razor blade that repair light are united in wedlock, make the function of new-style milling cutter and quality consistency reached the level that one defect breaks. The knife places but interchangeability raised security, durable sex greatly, reduced the cost of big diameter cutting tool and inventory. The weight of big diameter cutting tool when cutting is a problem, because aluminium of this CoroMill Contury is qualitative,the existence of cutter hub makes of cutting tool change to be held with clip more convenience. Milling cutter of type of partial knife clip ever incurred the risk that already machined exterior quality to be injured because of cutting bits, and the cooling fluid that quickens now is placed from every knife on the independent and cooling mouth of new-style design rushs forcibly, will cut bits to rush efficiently from treatment area, rose to machine security greatly. Craft of milling of a lot of cars is sensitive and subjective, because this is when the big diameter cutting tool that investment is representing very big cutting tool cost, ensure enough cutting tool has options consists is very important. The chamfer of razor blade of CoroMill razor blade that uses a level through be on CoroMill knife clip, a lot of different bit types can be used at big diameter milling cutter, include to use the bit that repair light in a few positions. The option that this imply places cutter of platform of this cutting tool in the knife has a lot of, the brand of coating hard alloy from newest generation (be united in wedlock with look of specific chamfer look) to more material of appropriative cutting tool for example nitrogen changes silicon pottery and porcelain, cubic nitrogen to change boron and PCD bit. Cutting tool of so big diameter can inspect existing application and actor is chosen. This is used for cutting tool choice and combination added flexibility, find optimal treatment solution easily. The can change a knife to placed a concept to represent two main processing technique that face auto industry progress of milling cutter of CoroMill 365 face and milling cutter of big diameter face. Use ILock technology to undertake screw cutting should mention the problem that produces in screw cutting, but the small displacement of dislocation razor blade is considered as an accident one of common causes. Cutting blade often can bring about the cutting tool life that shortens prematurely, asexuality in the slight shift in cutting process can consistency and cannot machine the effect satisfactorily. But, bit technology had new breakthrough recently, found make bit essence determines a method on knife handle, had implemented the striking change of cutting blade stability. This breakthrough pledges for harder, more durable knife sheet open a gate, reliable ground shortened treatment cycle time. In screw cutting, cause function not beautiful and treatment result unfavorable a lot of problems normally origin the neglect at main to common metal cutting factor, for example: Cutting tool is dangerous those who extend is the smallest change, of cutting tool stability the biggest change, the most appropriate to the medium, application that suits cutting parameter most and choice cutting tool of cutting blade and treatment method. The other of screw cutting is specific problem (the different method that includes the cutting depth that takes a knife every time, radial feed and to obtain enough the bit banking angle that place of the horn after big blade needs) whorl pitch and diameter and helix rise need basis part will decide. Regard whorl as the most typical characteristic, whorl tooth form and teeth shape error are the commonnest cause that off quality causes in thread machining, because unqualified place brings about tolerancepublic errand or exterior surface roughness,also may be. Should appear when this kind of circumstance, the service life of cutting blade is premature end normally. So far, one of main reasons that form body of incorrect whorl tooth are bit stability is lacked on knife handle. The profound shift of bit also can bring a few adverse consequence and cause cutting tool loss of life, among them the collapse blade that a main consequence is cutting blade, be in place of radius of point of a knife especially. Through choosing the clamp bolt that replace, must replace with U bolt normally for example change bolt quickly, stability can be improved on certain level. But until still solve bit to be in hard at present bit those who go up is completely fixed. The 2nd element is the beginning that the knife takes every time in screw cutting and end, this means the size of cutting force and direction to have abrupt change. These are the subtlest shift in machining working procedure process, get easily at the same time the influence of bit displacement risk. Of form of tooth of the whorl on bit most advanced form a lever with bolt, force cutting blade to change the position slightly and make the strong point in bit chamfer is out of shape. In the process of screw cutting, when the beginning that takes a knife every time and end generation joins the axial force that change, offset with the balance in cutting after be cut. This kind is handed in change axial force is from different way action on bit, generate the current that bit moves back and forth. The 3rd element, any change of whorl type mean the cutting force change on size and even direction, but bit dimension was not necessary to change as the change of whorl tooth form and in bit offer the different rate that prop up. And same bit size can have different pitch, this means the razor blade of big pitch not to have more propping up than the razor blade of small pitch. If bit dimension changes as the change of whorl tooth form and pitch, so the norms of bit and knife handle will must become super- many imaginary. Accordingly, the main consequence of cutting blade displacement is generation whorl out of tolerance and line of bit cutting blade is tiny burst apart. If be in,still keep stopping use cutting tool, so cutting tool wears away will faster aggravate. As a result of cutting blade happening wears away, bit can bear greater cutting power and the displacement that has the situation that enter a state, quicken the happening of breakdown thereby. In fact, bring about because of displacement change the circumstance of bit is morer than the circumstance that wear away because of real bit and changes. With respect to the whorl quality consistency in working procedure character, the exact location of cutting blade is very crucial. What bit locates is on the other hand but repeatability. To avoid time-consuming machine tool setting and the generation that decrease as far as possible or remove faulty part, bit is in the simple and easy and exact location in knife handle is very important. Normally the circumstance falls, bit dislocation makes produce whorl range in order to avoid in the course that should not taking a knife as far as possible receive a knife. If walking along the need in knife process to undertake bit dislocation, so the spirit that the acceptability to maintain and coming true key that machines a result is bit is certain. Be united in wedlock with this photograph, considering the influence of machine tool machine down time, it is very important also that the fast and simple and easy ground between the knife goes to undertake bit dislocation in two. The produces efficiency to finish place of whorl tooth form to need with screw cutting cutting tool greatly number taking a knife of screw cutting is relevant. If take knife time too much, again together with cuts deep inadequacy, can cause exceeding cutting tool to wear away to be heated up with attrition, bring about thereby fast hind knife face wears away and plasticity is out of shape. Small cut deep often also cause adverse effect to cutting bits to form, generate thin and hard pilot cuts bits. Less time taking a knife needs bigger cutting deepness, but cutting blade should bear more load. Through optimizing knife frequency, shortened the volume of penetration of a cutting tool that processed the time that complete whorl place needs to improve cutting blade. Cut the cutting force with deep taller generation greatly, increase bit to produce the trend of displacement in blade holder thereby, what this also emphasized bit locating reliably again is necessary. The another model characteristic of whorl is pitch, it falling in certain circumstance may be the cause that causes a spare parts to make mistake. Most pitch mistake comes from numerical control error, and when when unit of machine tool, control, setting and process designing any errors had been eliminated, can be opposite but dislocation razor blade in the stability in knife handle and cutting tool transverse feed means is opposite the influence of pitch undertakes assessment. The pitch of whorl is the element that a spare parts designs, fine tooth whorl is normally right below the circumstance tolerancepublic errand requirement is stricter, with respect to cutting character because unit millimeter or inch on fewer whorl amount (feed leads) , machine fine tooth whorl to need to spend longer time. But, snail runs to jump over need to tall feed is led and produce greater cutting power greatly more, this also needs very solid bit fixed position. As a result of the vulnerability of blade of the cutting in screw cutting, bit needs as far as possible hard and wear-resisting, at the same time not easy fragile crack, collapse blade risk is not had in machining a process. In modern treatment, cutting blade pointed place produces many heat in metal cutting, force cutting tool to must be had fight plasticity metabolic ability, after producing plasticity to be out of shape subsequently and coming is fast namely hind knife face wears away, if continue to use same cutting blade, can appear point bursts apart. Cutting blade suffers plasticity to be out of shape is the biggest obstacle that efficiency improves through cutting speed in screw cutting. Improper knife sheet makes character cutting blade discards as useless quickly and treatment gives unqualified whorl, subsequently occurrence cutting blade ruptures. Generally speaking, appropriate time taking a knife and when predicted bit life hind the effort that knife face wears away is screw cutting evenly target. However, to bear mechanical load especially the mechanical load with whorl tooth most advanced form, bit needs to have particular strength, bit material also needs to have a few reasonable tenacity character. To the whorl inside treatment, this one demand is very clear. Huo cuts working procedure to always accompanying cutting tool vibration, invite knife and the problem that discharge bits, because this proper toughness is right,bit function and dependability are having conclusive effect. Eliminated bit to offer the possibility that uses data of new cutting tool in the small displacement in bit chamfer, the instability that pair of treatment need not consider too much when the research and development with bit qualitative material gives make up for. Accordingly, the newest development of technology of matrix of fine grain razor blade offerred the distinctive matrix that has tall red rigid, the cutting tool that makes having sharp cutting blade is had fight plasticity to be out of shape ability, for example screw cutting, cut off and grooving and integral hard alloy establish milling cutter. GC 1125 is a kind of new PVD coating name, it is steel only screw cutting and optimize, also show to other work material at the same time very the function that breathe out. It manufactures efficiency through using higher cutting rate to rise -- restrict and often cannot use higher cutting rate of function because of cutting tool material in screw cutting. The matrix of GC 1125 is very hard, did not use any gradient technologies, because of its immanent toughness can provide enough cutting blade strength. PVD coating is one kind new-style multilayer azotic aluminium changes admire coating, deserve to be mixed with processing of cutting blade ER bit chamfer form, have very high edge security. The place before be like is narrated, the exterior blade of bit is pointed easy happening plasticity is out of shape, the bit place that machines whorl tooth top appears more easily with felt because of flaking wear away, form the tumour that accumulate bits thereby. GC 1125 regards PVD as coating, can better face of the knife after eliminating these trends to reach wears away. The cutting blade that knife face wears away to form whorl surface along treatment normally after appears, it is screw cutting the complement of current ability qualitative GC 1020, usable in order to optimize the manufacturing efficiency of thread machining working procedure. Material of razor blade of other complement whorl includes to take H13A of brand of coating of very sharp blame character, use at heat-resisting alloy, titanium alloy to mix certain and cast-iron. CB20 changes boracic material to pledge for cubic nitrogen, use at the screw cutting of hard data. Accordingly, be based on a lot of reason, the implementation that the quality of the fixed position of screw cutting razor blade in chamfer of knife handle razor blade and locking produces efficiency to Gao Sheng, safety is operated and decisive action reachs since consistency of spare parts quality. Use the bit locking in the past and location method, originally bit closely impossibly already below a lot of circumstances in bit chamfer. The clamp that the fixed, knife of bit fills up and simple and easy dislocation are meant namely eclectic, the confine of bit production method already block up the possibility that implementation breaks through traditional method. The development of the bit fixed position of cutting tool of CoroThread 266 screw cutting and locking concept, brought stronger security, longer cutting tool life and taller manufacturing efficiency. The influence that although be in cutting or dislocation process,is changed by cutting force, coroThread 266 also can locate ground of bit is accurate and close solid, this is a significant breakthrough to screw cutting. Series of this cutting tool and the posture of cutting tool of bit clamp system that adopt a convention are compared, can satisfy the requirement of taller stability. The knife is filled up to screw cutting working procedure it is very important, because this already undertook redesigning, the basis that provides security can be secured mediumly in knife handle for bit. Pass bit in the bolt that two firm interface and flank secure, knife mat offers its indispensible firm and exact location for bit, this is outside the accurate slideway interface of protruding, corresponding razor blade locates namely go up in this slideway. Knife reel is close bolt general razor blade is clingy go up in slideway and radial and an interface photograph lean, offerred very tall stability and exact location. When cutting, the slideway of the razor blade that prop up bears cutting force, bit any blade strong point do not have attaint risk. Fixed position slideway is perpendicular at feed direction. To precision character, coroThread 266 has very tall repetition fixed position precision, can ensure to razor blade of M class public errand edge axial (feed direction) ± 0.

05mm, it is ± to razor blade of E class public errand 0.

01mm. The speed that ILock slideway is bit dislocation and outfit clip are offerred convenient, the osculatory means of slideway and clearance are crucial to its function. The appearance of slideway and fixed position are pass a large number of research and development and get, set the exact strong point between knife mat and razor blade, and brand-new razor blade makes a technology can make strong point keeps consistent. What this technology disappear places besides bit outfit is incorrect in, improved knife reel to run a state thereby. The place on put together is narrated, the development of cutting tool of these 3 domains satisfied turning, milling and screw cutting directly car manufacturer is right the requirement of consistency of the quality in treatment function of improvement, ameliorative security and big batch production. The cutting blade as one of main and successful elements that serve as cutting is absolutely of stability rise, knife handle, but dislocation razor blade and both of a fixed position technology brand-new development had overcome existing confine thoroughly, leading auto industry machining to march toward more efficient. CNC Milling
