新材料加工所用刀具的基本条件新材料具有许多优异的性能，但从切削加工的角度来看，却有许多不利于加工的因素。新材料大多属于难加工范畴，其加工特点是：①工具寿命短；②切削阻力大；③加工表面粗糙度差；①切屑处理性能不好。另外。新材料的加工较少属于大批量生产．... New material processing tools used in the basic conditions New material has many excellent properties, but from the cutting point of view, there are many factors that are not conducive to processing. Most of the new materials are difficult to process, the machining features are: ① tool life is short; ② large cutting resistance; ③ poor machined surface roughness; ① chip processing performance is not good. In addition. Less processing of new materials belongs to mass production. ...
