milling grinding topic

A grinding machine is a tool or piece of equipment used for removing material from a workpiece via abrasion. They typically employ rotating abrasive wheels to shape, smooth, or finish workpieces through grinding. The machining process uses abrasive particles to remove material from a workpiece's surface.
