Definition of Grinding
Grinding, an abrasive machining process that uses a grinding wheel as the cutting tool, is capable of making precision cuts and producing very fine finishes. The grinding head can be controlled to travel across a fixed workpice or workpiece can be moved while the grind head remains in a fixed position.
A precision grinding machine consists of a power-driven grinding wheel spinning at the required speed (which is determined by the wheel’s diameter and manufacturer’s rating) and a bed with a fixture to guide and hold the workpiece.
Grinding Machines
Grinding machines remove material from the workpiece by abrasion. This process can generate substantial amounts of heat. A coolant to cool the workpiece is incorporated to alleviate overheating or being out-of-tolerance. The coolant also benefits the machinist as the heat generated in some cases may cause burns. In very high-precision grinding machines (most cylindrical and surface grinders), the final grinding stages are usually setup so that they remove about 2/10000mm (less than 1/100000 in) per pass
