在钻模板的镗孔加工中,我们对刀具作了一些改进,并更新了传统的镗孔工艺流程.七年来,采用改进后的立铣刀精镗各类钻模孔数十万个,均获成功,成倍地提高了工作效率和产品质量,现将经验介绍如下.1.方法.(1)将相应的立铣刀外圆刃由外圆磨床磨至需钻孔径的公称尺寸,正端面刃处留3～5mm作修光刃用,此后磨0.08倒锥.由工具磨床将外圆刃磨出后角.用细油石修磨各刃口,人为地消除刀具的初磨损阶段,尽量延长刀具的正常磨损阶段,增加刀具的使用寿命,实践证明,其外圆刃的磨损甚微.外圆刃的磨倒锥的目的是不使修光刃之后的外圆刃口碰擦已加工过的内孔表
In the boring process of the drilling template, we made some improvements to the tool and updated the traditional boring process. In the past seven years, we adopted an improved end mill to finish boring hundreds of thousands of holes Successfully, doubled to improve the work efficiency and product quality, experience is introduced below .1 method (1) the corresponding end milling cutter cylindrical grinding machine to be required to drill the nominal diameter of the hole size, Is the end of the edge to stay 3 ~ 5mm for the wiped edge, then grinding 0.08 inverted cone grinding wheel by the tool to grind the outer corner of the horn with a small oil stone grinding the cutting edge, artificially eliminate the initial stage of wear tool, Try to extend the normal wear stage tool to increase the service life of the tool, the practice proved that the outer edge of the wear and tear is minimal.The purpose of grinding the outer edge of the outer cone is not wiping the outer edge of the wiper has rub Processed hole table
