[Introductive] Normal > is current, home is used at machining cast-iron tool to basically be hard alloy cutting tool, corundum (or carborundum) grind etc, in use of this kind of tool is existing generally to machine efficiency security of difference of quality of low, treatment, tool is low defect, it is wear-resisting character in treatment material especially cast-iron and cast-iron when sand bed of white mouth layer, pregnant, this kind of tool is shown apparent incommensurate. Draw lessons from company of Japanese benefit root about cast-iron cut off curium with diamond piece design train of thought, producing akin product while, we are outspread developed the series product such as diamond grind segment, diamond bit, make stone tool satisfied King Kong to be aimed at a cast-iron chamfer, cut off, long grind, the requirement of a few kinds of different exercise such as bore. Comparative at traditional tool, diamond tool is machining effect of quality, service life, treatment to lead twice of index of a few respects rise, show efficient, low cost, safe characteristic. Normal >[technology program and principle] Normal > this tool is used eletroplate (electroform) means is made, manson of King Kong of bond of metal of the plating that belong to report is provided. Normal > is aimed at the character of cast-iron material and diamond tool to reach use requirement, in the design of the tool the crucial problem that solved the following respects emphasizes in making: Normal TEXT-INDENT of combinative strength problem between film of 21pt">1, metal and matrix: 21pt"> is cast-iron cut, grinding treatment often is to be in a kind not to have cooling water environment in, work namely cut, dry grind, to eletroplating kind of product, make the temperature of tool oneself elevatory without cooling exercise, make extremely easily the craze between film and matrix, bring about film to fall off. To solve this one difficult problem, adopt the following kinds of designs: Normal >1) the material of matrix chooses alloy steel of small coefficient of expansion character, those who choose the metallic salt that approachs matrix ability qualitative part to regard plating as fluid advocate salt, reduce the difference of hot coefficient of expansion that material differs between matrix and film; Normal >2) matrix surface beforehand plating Cu layer serves as transfer layer, increase the combinative strength between matrix and film; Normal >3) matrix uses electricity activation technology; Normal >4) on arenaceous plating and add thick plating working procedure to use recipe of different plating fluid, improve position of film internal stress, reduce film unusual fall off element Normal MARGIN-LEFT of 21pt">2, treatment efficiency problem to workpiece: 21pt"> is provided as a result of King Kong manson is with its diamond small cutting blade realizes pair of cast-iron treatment, accordingly, in using, easy occurrence cutting blade is cut bits jams or grind blunt and the situation that affects efficiency, to solve this one problem, adopt following designs: Normal >1) choose single crystal of diamond of high grade thick grain to regard cutting as blade; Normal >2) add generous time to control diamond grain to be in film through control embedded deepness, ensure give blade height on average 0. 1mm above Normal >3) optimize eletroplate craft, use plating liquid loop, filter, the method such as profile modeling positive pole, improve the distributinging position of line of the power in electric field, make film level off, reduce metallic tumour occurrence Normal MARGIN-LEFT of 21pt">3, safe problem: 21pt"> uses high grade board, design reasonable configuration, eliminate stress to center a circumstance, avoided Normal >[experiment and application] Normal > is based on afore-mentioned principles, the design made the diamond tool that gets used to different exercise circumstance: Normal >1, diamond curiums a design plan that this product adopts actor to choose, with Yu Zhu iron annulus of canal of rising head, casting, piston the grooving that wait, cut off working procedure. Normal > matrix uses anneal alloy board, cutting blade uses single crystal of diamond of granuality of MBD12 class 40/45, to prevent to curium piece be affected to use by cut in the matrix in exercise, in matrix two flank screening glass of single crystal of RVD70/80 diamond of 2 plating Fu. Normal > this product has following requirements cut off an experiment: Normal > experiment machine: Stationary cuts machine RC-16 power: 2.
Rotate speed of 2KW main shaft: 1900r/min Normal > severs a boy or girl friend: HB230 Normal > experiment means: Load: 2Kgf does not have refrigeration, cut off Normal > test data is as follows: Normal Align=center> curiums a norms Normal Align=center> cuts off quantitative Normal Align=center> spends time: Normal Align=center>12 inch Normal Align=center> Normal Align=center>15 Normal Align=center>14 inch Normal Align=center>1 Normal Align=center>20 Normal > application makes clear, this product life is equivalent to be the same as norms colophony cut piece 50-80 times, and handle convenient, security intensity of tall, labor is low. Normal > exterior and norms pursue as follows: Normal >2, diamond grinds a Normal > this product uses Yu Zhu iron rising head clears, what flash, arris pricks is cleared the Normal > matrix uses cold rolling board, the finish machining after mould pressing shapes and into. Abrasive chooses granuality of MBD8 grade 40/456. Normal > application makes clear, the 30-50 that this product life is equivalent to be the same as norms colophony cymbals emery wheel times, and security is extremely high. Normal > exterior and norms pursue as follows: Normal MARGIN-LEFT of 0cm">3, diamond bit: 18pt; TEXT-INDENT: 21pt"> is used in the operation of drilling extraction core of iron pipe of the casting below special situation. Normal > matrix employs capable person of 45 steel tube, abrasive chooses granuality of MBD8 grade 40/456. Normal > application makes clear, this product characteristic is efficient, security is extremely high Normal > exterior and norms pursue as follows: Normal >[conclusion] via reasonable design and experiment, the proof can use the diamond tool that optimizes craft to undertake machining to cast-iron material, this kinds of tool shows good performance characteristics.
