前言这一实验研究是结合济南机车工厂64年度的生产关键问题(旋风铣扣刀具耐用度低。)而进行的。为了提高刀具耐用度,避免刀具折损、提高加工表面质量及生产率。分别进行了不同铣切方法的实验、刀具合理几何参数的实验、不同牌号硬质合金刀具的切削实验、四齿内螺纹硬质合金铣刀的切削实验以及扩大旋风铣加工范围的实验等。并相应地改进了夹具、 Preface This experimental study was conducted in conjunction with the 64th annual production key issue of Jinan Locomotive Works (cyclone milling cutter with low durability). In order to improve the durability of the tool to avoid tool damage, improve the processing surface quality and productivity. The experiment of different milling method, the experiment of reasonable geometric parameters of cutter, the cutting experiment of cemented carbide cutter of different grades, the cutting experiment of four-tooth internal thread cemented carbide cutter and the experiment of expanding the scope of cyclone milling were carried out respectively. And accordingly improved fixture,
