前言镀有TiN的高速钢滚刀能减少磨损,本文报道了有。无镀TiN的高速钢滚刀在高刚性滚齿机上大批量加工模数较小的齿轮(如汽车传动齿轮)时滚刀损伤的研究,并阐述了如何有效地使用这种滚刀,有以下几点: (1)、TiN镀层的要点; (2)、改善后刃面的表面粗糙度; (3)、镀TiN滚刀的后角应较小些; (4)镀TiN带凸台齿形滚刀可减少磨损。一、高速或高效滚齿时滚刀的损伤 1.棱角磨损 Preface TiN-plated high-speed steel hob can reduce wear, this article reported there. TiN-free high-speed steel hobs High-rigidity hobbing machine for large-scale processing of small modulus gears (such as car transmission gears) when the hob damage, and describes how to effectively use this hob, the following Point: (1), TiN coating points; (2), to improve the surface roughness of the rake face; (3), after plating TiN hob should be smaller; (4) Hobs reduce wear and tear. First, high-speed or efficient Hob hob damage 1. Angular wear
