The 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,Grinding - Longmont Machine Shop usually by a formula) and a bed with a fixture to guide and hold the workpiece. The grinding head can be controlled to travel across a fixed workpiece or the workpiece can be moved while the grind head stays in a fixed position. Very fine control of the grinding head or table position is possible using a vernier calibrated hand wheel, or using the features of numerical controls.

Grinding machines remove material from the workpiece by abrasion, which can generate substantial amounts of heat; they therefore incorporate a coolant to cool the workpiece so that it does not overheat beyond its tolerance. The coolant also benefits the machinist as the heat generated may cause burns in some cases. In very 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 1/100000 in) per pass - this generates so little heat that even with no coolant, the temperature remains tolerable.

Types of Grinding Machines:

  • Belt grinder: With the aid of coated abrasives, belt grinding is a versatile process suited for applications such as finishing, deburring and stock removal.
  • Bench grinder: Manually operated and used to shape tool bits.
  • Cylindrical grinder: Used to make precision rods, a cylindrical grinder has multiple grinding wheels to form a cylinder.
  • Surface grinder: A grinding wheel on which a workpiece is moved back and forth upon.
  • Jig grinder: Primarily function is to grind holes and pins as well as complex surface grinds on work started on a mill.
  • Gear grinder: The final machining process when manufacturing a high precision gear.
