Get the 3 gist element that cuts treatment

In bore process, want to improve productivity, not be the most complex treatment issue it seems that, but 3 following the mainest factors get immediate impact cut speed, public errand and cutting tool life, namely: Cooling fluid cooling fluid can maintain get a needle to be in quite low job temperature, and conduce to prolong the life of cutting tool. In an aperture caloric is accumulated can bring about auger the needle is curly, make its cutting blade becomes blunt, make thereby it " plow " pass work. Such meetings cause broach to break off in Kongzhong. A few people think the sole function of cooling fluid is cooling, but Gregory S of ChipBlaster company president.

Mr Antoun says, cooling fluid still has the effect of other. Cooling fluid can maintain get a needle to be in an appropriate working temperature, still can maintain workpiece to lubricate. Lubricant conduce to get a needle to hold its sharp cutting blade, prolong its life. Mr Antoun says: "In fluid of a kind of cutting, the chroma of lubricant depends on add workpiece and cutting tool. The odd blade lathe tool with very small interface, the chroma of the lubricant in cooling fluid is achieved 5% OK. When you increase the interface of broach, chroma must increase to 8% at least. " he still says, the tap after bore, the lubricant chroma with the highest need in cooling fluid is 12% , the chroma when bore is reduced also can make cutting tool life decreases 90% . In the meantime, cooling fluid is returned can cut bits to go out from Kong Zhongchong. Seco-Carboloy gets cut product manager Frederik-Sundstrom to say: "If you not cut bits to go out from Kong Zhongchong, can break off broach. " likewise simple truth, the meeting that cut bits binds the point of a knife, point of a knife that lock up a place of strategic importance, card to live point of a knife, cinch point of a knife, make broach breaks off. Mr Herman points out, mechanical workers of Europe are used a few cooling fluid, combine those who use a workshop to compress air, will decrease auger cut a large number of cooling fluid that need normally. ChipBlaster company, Seco-Carboloy company and American Komet company are recommended, the pressure of cooling fluid should maintain in higher level, mr Herman and Mr Sundstrom say, very high pressure can improve the efficiency of cooling fluid only. Additional, 3 companies are recommended, when machinist person is undertaking Kong Jia is versed in, want to use the cooling fluid technology that adopts cutting tool, but often do not do. The cooling fluid technique that adopts cutting tool has a restriction. Be close to when the dimension of aperture 0.

1969 inches (5mm) or more hour, often cannot pass broach supply cooling fluid, must use technology of exterior cooling fluid. Although a few model broach or G broach, be less than when norms 0.

1969 inches when, also can offer through technology of cutting tool cooling fluid, but often need to use the technology that peck aperture to drill so small hole. Sale chief inspector Mr Mike Herman of American Komet company says: "Pecking Kong Shi, machinist person bore arrives of its diameter 1 or 2 times when, need undertakes Kong Qing manages, rinse with exterior cooling fluid namely, cut bits in order to keep clear of. Although peck aperture very between take time, but it is better that this always compares another kind of situation. " he says, "If you broke a little bit in a Kong Zhongshe, so you may need to use method of cut of electric spark line, ability takes bit, or you will are faced with possibly should discard as useless a value the danger of thousands of yuan workpiece. " get Mr Sundstrom that cuts main shaft speed and firm of feed rate Seco-Carboloy to say: "Find get correctly cut main shaft speed and feed rate, it is to get the 2nd crucial factor that productivity improves in cutting. " tool supplier is in their trade catalogue, offer the detailed detailed account of data of cutting cutting tool, those norms must accurate abide by. Cutting tool produces the norms of business to also conduce to machinist person making a decision, which kinds of cutting tool is the cutting tool of optimum treatment workpiece, these cutting tool include: Hard alloy or the broach that set blade, high-speed steel broach, solder broach, small helix angle (12 ° helix angle) twist drill or standard twist drill of 35 ° helix angle first. For example, twist drill of small helix angle applies to particularly hard data normally, also apply to the tacky material when those are machined, wait like titanium. The tigidity of cutting tool clamp is final, the tigidity of cutting tool clamp also is to raising the factor with get one of cutting efficiency particularly main. If workpiece clamp is bad, the exterior quality difference that will cause aperture, quiver and a lot of other issues, can cause a spare parts to discard as useless even, can lower the working life of broach.
