Surface grinding is a machining process used to produce a smooth finish on flat surfaces. It involves a rotating grinding wheel that removes material from the workpiece, which is typically made of metal or other hard materials. The workpiece is held in place on a table, and the grinding wheel moves across its surface, ensuring precision and accuracy. This technique is commonly used in manufacturing and engineering to achieve tight tolerances and improve surface quality. Surface grinders can vary in size and complexity, from small manual machines to large automated systems, making them versatile tools in various industrial applications.
