Parts worn out during finishing process due to defects of grinding operation The defects are chatter marks, helical type scratches, surface cracks, etc., In certain circumstances high surface quality is required Hence for removing grinding defects, to obtain desired surface finish and to improve the geometrical shape finishing processes are used

The grinding process has the least material removal rate among other machining processes because of the following reasons- Size effect: As above discussed the machining is done by the abrasive action of grinding wheel that's why a large portion of the abrasive will be embedded inside the wheel and a small portion of abrasive will be allowed to interact with them, therefore, less material is

A surface machining process, such as conventional grinding and lapping, introduces damages into ground surface layers of ceramic materials [10-12]. Excessive forces during the grinding process generate defects such as chips, cracks, flaws, and/or fissures. The grinding defects decrease the strength of ceramics [13, 14].

Centerless grinding is a machining process that uses abrasive cutting to remove material from a workpiece. Centerless grinding differs from centered grinding operations in that no spindle or fixture is used to locate and secure the workpiece; the workpiece is secured between two rotary grinding wheels, and the speed of their rotation relative to each other determines the rate at which material

Grinding operations thus contribute greatly to the quality of the finished workpiece. However, problems can often occur during the grinding process. The biggest and most known problem is without doubt grinding burn, which is thermal damage to the rim zone of the part. Grinding burn occurs when too much heat is channelled into the part.

This is the perfect process that helps you in grinding the turbine blades. It is widely used in the aerospace industry. This type of machining process is also used in the sharpening of the needles. It is used for eliminating the defects on the metal surfaces. In this article, we took a brief glance at the electrochemical grinding.

Apart from thermal heating there are several other problems which may arise during the process of grinding. For example the grinding wheel might be wearing too soon and this can be rectified through the use of harder wheel so that its relative hardness is much more compared to the work piece.

grinding machines perform the dressing task automatically. The application of coolants to the grinding process is important. Coolants reduce grinding machine power requirements, maintain work quality, stabilize part dimensions, and insure longer wheel life. Coolants are either emulsions, synthetic lubricants or special grinding oils.
