A grinding machine or grinder is an industrial power tool that uses an abrasive wheel for cutting or removing the m aterial. It is a process of metal cutting by using a rotating abrasive whee l from the surface of the workpiece. Generally, the grinding is finishing operation to show the high surface quality, accuracy of the shape and dimension.
Grinding Machines are also regarded as machine tools. A distinguishing feature of grinding machines is the rotating abrasive tool. Grinding machine is employed to ... equipped with an additional head for internal grinding. Schematic illustration of important features of this machine is shown in Fig.29.10.
The schematic diagram of ECG system is shown in Fig. 6.3. In ECG system, rotating conductive metal bonded abrasive grinding wheel acts as cathode and workpiece acts as anode in electrolytic cell. The wheel rotates at a surface speed of 20–35 m/s. Bonding materials are copper, brass, bronze, nickel or copper impregnated resin.

The surface grinder opens up new possibilities because it could allow you to harden the things you make and machine them to a much closer tolerance. A surface grinder is an outstanding cut-off the instrument for reducing toughened shafting. The material used in surface grinding is 0.25 to 0.50 mm. Surface grinding is best if used for flat cutting.
Grinding machine is a type of machine tool and it is similar to other machine tools such as milling machine, turning machine, Lathe Machine and many more. The major difference between Grinding machine and other conventional machine tools is the type of operation and method of machining. Generally, all the machining process removes material …
Advent of advanced grinding machines and grinding wheels has elevated the status of grinding to abrasive machining where high accuracy and surface finish as well as high material removal rate can be achieved even on an unhardened material. The bulk grinding wheel – workpiece interaction as given in Figure 2 can be divided into the following

The common grinding machine operation are surface, cylindrical, internal and centreless grinding. Now let us discuss each one by one, 1. Surface Grinding. It involves grinding flat surfaces. Here the workpiece is fitted with a magnetic chuck attached to a work table of the grinder. Non-magnetic are held by vices or fixtures.
Machine should be connected to the supply via a 20A breaker. The top of the reel and the top of the grinding wheel should both move away from the front of the machine (i.e. both rotate clockwise when viewed from right hand end of the machine). In this way, the reel and grinding wheel are moving in OPPOSITE DIRECTIONS at the point of contact.
