A grinding machine is a machine tool that uses a rotating abrasive wheel to change the shape or dimensions of a hard, usually metallic, object. Itís often used to produce very fine finishes or very light cuts. While sanding is the machining of wood; grinding is the common name for machining metals.

Machine grinding works by removing unwanted layers of material from the workpiece by a process of abrasion. Grinders can be set to a high-precision, especially the cylindrical and surface versions. In final grinding stages they are usually set up so that they remove about 2/10000mm (less than 1/100000 in) per pass.

There are many types of grinding machinery but belt grinders used to process metals and other materials are one of the most popular types. Angled grinder machines are generally considered the most suitable for manual tasks such as finishing, de-burring, patterning, cutting, and polishing.

Other types of grinding machine include the cylindrical grinder which is used to make precision rods; the surface grinder, which has a Ďheadí that is lowered and the workpiece is moved back and forth past the grinding wheel; and the jig grinder, which has a variety of uses when finishing jigs, dies, and fixtures. Although mostly used for grinding holes and pins, it can also be used for complex surface grinding to finish work started on a mill.

Grinding Machines


Grinding machines consist of a power driven grinding wheel which spins at the required speed. This is determined by the wheels diameter and manufacturers rating, usually by a formula and a bed with a fixture to guide and hold the work-piece. The grinding head can be controlled to travel across a fixed work-piece or the work-piece can be moved whilst the grind head stays in a fixed position.

Grinding is the most accurate of all the basic machining processes. All grinding machines use a wheel made from one of the manufactured abrasives; silicon carbide or aluminium oxide.

Grinding machinery removes material from the work-piece by abrasion, which can generate substantial amounts of heat, they therefore incorporate a coolant to cool the work-piece, so that it does not overheat and go outside its tolerance. The coolant also benefits the machinist as the heat generated may cause burns in some cases.

There are various types of grinding machines. These machines include the Bench Grinders which usually have two wheels of different grain sizes which are used for roughing and finishing operations. They are usually secured to a workbench. Bench grinders are an example of manual grinders. They are used for shaping tool bits or various tools that need to be made or repaired.

Rotary grinding machines tend to have multiple grinding wheels. Here, the work piece is rotated and fed past the wheel to form a cylinder. Surface grinders have a \\\"head\\\" which is lowered, and the work piece is moved back and forth past the grinding wheel on a table which has a permanent magnet for use with magnetic stock. Surface grinders can provide an example of hand held grinding machines which are manually operated some however have CNC controls meaning that they are computer operated.
