Non-standard precision parts require high precision in machining. To achieve super-lubricated appearance and high machining accuracy, natural tools require high demands. If the tool wears, the machining surface quality Will be reduced. And in the ultra-precision cutting, unlike the general cutting rules, the cutting speed is not limited by the standard tool life.
Non-standard precision parts generally choose the smallest speed when machining, which is determined by the transmission characteristics and cutting characteristics of ultra-precision machine tools, because the minimum surface roughness can be achieved at the minimum speed, thus ensuring the highest processing quality. Of course, the premise is to ensure that the quality of machine tools can drive high cutting speed to ensure the efficiency of processing.
