Centerless grinding is the process of removing material from the outer diameter of a workpiece using a grinding wheel. The workpiece is located on its outer diameter and supported by a working blade located between the adjusting wheel and the grinding wheel. The adjustment wheel drives the machined parts, and the grinding wheel removes material.

Coolant is used in centerless grinding to not only keep the grinding wheel cool, but also remove heat from the zone where the workpiece contacts the grinding wheel. Centerless grinding requires the use of correctly pressurized coolant to overcome the air barrier created between the grinding wheel and workpiece during the grinding process.

It is a smoother process than any other machining processes. Sometimes many machining processes result in damage to the workpiece but in case of the electrochemical grinding, the workpiece is not get affected at all. Also, it causes the wear and tear of the grinding wheel in a very small proportion.

Hence, the actual grinding depth of the grinding wheel is smaller than the preset value, which helps to reduce grinding force and suppress the deformation of workpiece. After abrasive grinding, the ground part of the workpiece still suffers secondary corrosion, so that the total grinding depth of the whole machining process is larger than the ...
