Machine tool - Basic machine tools | Britannica Grinding machines remove small chips from metal parts that are brought into contact with a rotating abrasive wheel called a grinding wheel or an abrasive belt. Grinding is the most accurate of all of the basic machining processes. Modern grinding machines grind hard or soft parts to tolerances of plus or minus 0.0001 inch (0.0025 millimetre).
Total Runout – GD&T Basics Total runout is a little more difficult to measure because your height gauge must remain at a fixed height and normal to the surface you are measuring. It is often enough to control runout alone for many functions, and then specify a straightness (or angularity for a taper) tolerance, to ensure the form is consistent along the surface.
