一、前言低粗糙度磨别（通常也称低粗糙度精密磨削）可获得R。O．16～O．OO6pm的加工表面粗糙度，而且工件形状和尺寸精度也比较高。所以大部分高精度和低粗糙度的零件质量都是通过精密磨削来达到的，经过淬硬的高精度零件更是如此。与手工研磨相比，它的生产效率高，易实现自
First, the introduction of low-roughness grinding (usually also known as low-precision grinding) can be obtained R. O. 16 ~ O. OO6pm processing surface roughness, and the workpiece shape and size accuracy is relatively high. So most parts of high-precision and low-roughness quality are achieved by precision grinding, especially after hardened high-precision parts. Compared with manual grinding, it’s highly productive and easy to implement
