What Is Grinding Machine?- Definition, and Types ...
In high-precision grinding machines (most cylindrical and surface grinders), the final grinding stages are usually set up so that they remove about 200 nm (less than 1/10000 in) per pass – this generates so little heat that even with no coolant, the temperature rise is negligible. Types of Grinding Machines.
