To satisfy these requirement on the market, we were developed the smallest form is other on the world exceed cutting tool of accurate diamond cutting (cutting tool of figuration of UPC small accept) . The UPC that the article will introduce us to make (cutting tool of cutting exceeding essence of life) function, and the application in three-dimensional appearance small treatment. UPC exceeds the function of cutting tool of cutting of diamond of essence of life to exceed cutting tool of cutting of diamond of essence of life to use single crystal diamond to regard cutting tool as material. Because used the exceedingly good character of diamond material, cutting blade is very sharp and durable, but the motion superfinishing machine tool is accurate answer mirror be gotten on by treatment workpiece material, because this can be used at high accuracy the treatment of three-dimensional appearance and lens face face. Cong Yawei rice reachs dimension range of accept rice class exceed imperceptible cutting to ask to obtain condition of the following cutting: The cutting blade with sharp ① , radius of circular arc of point of a knife achieves left and right sides of 10 accept rice; Of ② cutting blade bright and clean the level that spends a requirement to achieve 1 accept rice. Radius of circular arc of point of a knife is smaller, cutting deepness is smaller also, the cutting that cuts bits and purify process ability undertake smoothly and won't damage treatment surface, in addition, because workpiece is stretch the cutting ply change that be out of shape and causes is less also, can realize tall accurate cutting to machine thereby. The cutting blade circular arc of UPC cutting tool can achieve 50 accept rice or smaller. If the finish machining surface of cutting tool outline is complete answer mirror workpiece to go up, criterion the surface roughness that the surface roughness of blade of cutting tool cutting will decide to machine the surface. Accordingly, the smoothness or evenness on rubber roll surface of cutting blade and appearance precision become be of exceptional importance. With respect to UPC-R character, we had achieved the world highest precision that be equal to or is less than 50 accept rice. To achieve such cutting performance, we developed proprietary high accuracy to survey a system by oneself. In addition, system of applied diamond polish, using scientific method to choose diamond and way of its crystal lattice also is very necessary and indispensable. Have a technology only through applying these, we were developed the smallest form is other on the world, be used at three-dimensional small form cutting exceed cutting tool of accurate diamond cutting -- cutting tool of figuration of UPC small accept. Cutting tool of figuration of UPC small accept up to now, three-dimensional small form cutting is to show small machining and semiconductor make a technology normally (if photoetching machines law, ion bundle treatment method) . These treatment methods have its insufficient place, if obtain slick curved surface hard, this is decided by their figuration characteristic place, because tilt,plane and curved surface are to pass pace move upon close and of figuration. As contrary as this, by sharp cutting blade finishs the cutting of the three-dimensional small form cutting that is based on cutting tool of cutting of diamond exceeding essence of life and figuration process, because this can be obtained,tilt glossily plane or curved surface. In addition, our cutting tool still has the character via was being improved, if have very tall appearance precision. Another advantage is the choice scope that increased material. Because have above characteristic, be in all the time to the demand of this kind of cutting tool in recent years constant growth, it is used at the treatment of photoelectricity foundation component not only, and in system of personal computer cable (MEMS) , small machine and biology medicine domain have demand. We developed the cutting tool of small accept figuration of 3 kinds of types already successfully, will introduce example of its form cutting below. Rectangle of UPC accept rice establishs rectangle of rice of milling cutter accept to establish milling cutter to use Yu Chao chamfer of fine free curved surface form cutting. We had developed a world to go up radius of other, circumgyrate is the smallest step only the single crystal diamond of 30 μ M establishs φ milling cutter. As above, be machined through undertaking exceeding polish of essence of life to single crystal diamond and the point of a knife that accept rice establishs milling cutter is made, cutting blade is very keen, flat with wear-resisting. This kind of cutting tool expects the spare parts of chip of component of applicable Yu Guangxue, medical treatment and personal computer instrument slot that includes three-dimensional curve treatment. It is clear that rectangle of UPC accept rice establishs example of milling cutter form cutting to use accept rice to establish milling cutter and circumgyrate radius to the cutting tool of 200 μ M undertakes to the mould three-dimensional milling is machined and form the treatment example that exceeds fine chamfer make clear, the motion of figuration cutting tool passes cutting tool by accurate answer mirror be gotten on by treatment workpiece, and did not form any burr. Surface roughness of bottom land surface (P - V is worth) achieved 101nm. Head of ball of UPC accept rice stands milling cutter to be in with IT (IT) in relevant industry domain, the fundamental cell development that is used at information of high speed high capacity is very rapid. Among them a kind of technology is small lens array. This array structure by a series of compositive convex and concave lens are combined and become by three-dimensional measure. In recent years, this lens array is applied at glossy news report and liquid crystal screen. The treatment that the head of ball of UPC accept rice that we develop stands milling cutter to be able to be used at achieving three-dimensional lens surface and free curvature appearance (the pattern that if machine,creates small lens array) . We had developed the measure of circular arc of point of a knife on the world (R ＝ 30 μ M) , can make an outline of cutting blade circular arc that reachs world top level spend (50nm point of a knife) . Use this kind of cutting tool, possible implementation has the three-dimensional appearance form cutting of accept rice precision. Head of ball of UPC accept rice stands milling cutter to machine example to establish milling cutter milling with head of accept rice ball treatment is three-dimensional model the form cutting example of the face can confirm, the head of accept rice ball that uses M of radius R=300 μ stands milling cutter, can form cutting goes out have extremely what high ball form spends is spherical with the high accuracy surface that does not have burr. Measure an instrument to measure the appearance precision of a small ball and socket with exterior form appearance, its P-V is worth (peak - peak value) for 166nm. Knife of grooving of UPC accept rice (exceed cutting tool of fine chamfer cutting) two kinds of Namili of above introduction milling cutter is to be used at milling to machine, and knife of accept rice grooving is to use shave is cut and fly cut means to process favorable balance of trade in workpiece figuration surface fine linear chamfer. We had been machined gave the world the chamfer of 5 μ M of the smallest level is wide. This cutting tool has representative application most is pair of holographic and optical component (HOE) the mould undertakes form cutting. This optics component is a polarization spectroscopic, the exceeds fine chamfer lens that its have the aid of amounts to micron class at having span of a group of chamfer produces smooth diffractive phenomenon, the random that realizes spectrum thereby is decomposed and gather together. The optical action synthesis of a certain number of optical lens is a holographic and optical component (HOE) . These optical component are to use semiconductor processing technique previously (like photoetching law) will make, but when using this method to machine, the bottom brim that should be orthogonal chamfer originally is changed by round horn; When machining deep chamfer, because figuration process of groove is decomposed to be the figuration that divide a pace for many times, because this meeting produces horizontal difference, and these horizontal difference can lower smooth utilization rate. With this treatment the method differs, those who use knife of accept rice grooving to machine the mould take shape that give to make is plastic and holographic optical component (HOE) the appearance precision with be had better and exterior surface roughness. In addition, this method still has the advantage with treatment tall efficiency. As in recent years the development of photoelectricity technology, right smaller exceed fine chamfer the demand of form cutting still is increasing ceaselessly. The characteristic that the article introduced cutting tool of figuration of UPC small accept mixes conclusion the example of three-dimensional small form cutting that is based on machining. In the three-dimensional and imperceptible form cutting that uses diamond cutting cutting tool, appearance of point of a knife by high accuracy ground answer is mirrorred be gotten on by treatment workpiece. Without doubt, on the application of technology of exterior form cutting, prospective market will machine precision to raise taller requirement to accept rice measure. Improving technology of the athletic performance that exceeds machine tool of accurate form cutting, control and the precision below treatment ambient conditions ceaselessly with rise, accordingly, the precision that we will devote oneself to to raise diamond cutting cutting tool further makes its miniaturization.
