The machining accuracy of grinder is higher than that of turning and milling. Why?
Publisher: Administrator Date：2021-07-14
Grinding machines generally use abrasive tools (grinding wheels) for grinding. The linear speed of the grinding wheel is high, the amount of knife is small, the accuracy is high, and the efficiency is low;
However, lathes and milling machines use cutting tools for cutting, which have a large feed rate, low precision and high efficiency.
There is also the highest precision in super-finishing. The abrasive used is whetstone, but only a few micrometers can be cut.
