一、概述铰削加工是机械制造业中一种通用工艺。铰刀是比较精密的刀具,其结构形状并不复杂,却可加工出较高精度与光洁的孔。因其加工成本低,效率高,特别适合于大量生产。然而,要想得到精度高、光洁度好的孔,除铰刀设计结构先进合理、制造质量优良之外,还与被加工材料的性质、工艺方案、切削用量、机床精度、润滑冷却液、操作方法等均有关系。若稍有不适当,则铰孔的光洁度就难以达到产品设计要求,甚至尺寸精度也不易保证或二者均不稳定,且刀具寿命短,这是在生 First, an overview Reaming is a general process machinery manufacturing industry. Reamer is a more sophisticated tool, its structural shape is not complicated, but can be processed with high precision and smooth hole. Because of its low processing costs, high efficiency, especially suitable for mass production. However, in order to obtain high precision, good finish hole, in addition to advanced and reasonable reamer design structure, manufacturing quality, but also with the nature of the material being processed, process options, cutting dosage, machine precision, lubrication coolant, operating methods All have relations. If slightly inappropriate, then the reaming of the finish is difficult to achieve product design requirements, and even dimensional accuracy is not guaranteed or both are unstable, and the tool life is short, which is in life
