Special broach designs aluminium alloy new thinking

02mm point writes the account that grind; ● is conic advocate hind horn. Stem from same reason, advocate hind horny design increases from 10 ° of the standard for 12 ° , in order to reduce the contact with workpiece material; ● first flank is narrow. This kind of distinctive N chamfer design, its first flank is narrower than common broach 40% , the aperture in reducing cutting process thereby and the clash that produce between broach are hot, the adhesion of the tumour that accumulate bits that with preventing quantity of heat exorbitant place produces is on broach first flank, can make the quality of aperture and precision get assuring adequately; ● pours awl (the horn after axial) . Pour awl (the horn after axial) for 0.
5mm/100mm, it is 2 times of standard hole size, this also can decrease auger cut with the direct contact between aperture surface; ● DLC film. This is not the diamond film on groovy meaning. It is film of a kind of low attrition, its purpose depends on increasing the capacity that discharge bits, this is the key that gains a success. Main good point is to have " not adhesion " characteristic, this very serious to capturing a lot of aluminium alloy material are for treatment problem, increased platoon bits capacity already, also improved the craft problem that solves hard before in treatment of bore of aluminium alloy material; ● optimizes the chamfer that discharge bits. Offerring good platoon bit is very important, to realize this demand, the chamfer that discharge bits is designed more widely deeper, can none eduction of suffocate suffocate ground is manier cut bits.
