New Innovations in ID/OD Grinding Operations. March 24, 2020 - Grinding. Like other segments within the metalworking industry, grinding machine technology has evolved over time to meet industry trends, including new advanced materials, increased demand for high-precision parts, 24/7 operations, and an acute shortage of skilled machine operators.


Grinding is a metal cutting process in which the material is removed from the workpiece by the abrasive action of rotating cutting tool known as a grinding wheel which rotates at a high speed (v= 10-80 m/s) while the work is fed past the wheel at a rate of 0.2 m/s to 0.6 m/s. It has some similarity with up milling operation except that the cutting points are irregularly shaped and randomly ...

An understanding of grinding wheels and processes allows operators to perform grinding operations effectively and recognize and address any grinding wheel problems that may occur. This understanding and recognition will improve the accuracy, precision, and overall success of grinding operations, reducing scrap parts and increasing productivity.


The grinding machine can be used to perform different operations. This is the reason why some special types of grinders are designed to specifically carry out some of the operations. Today we'll be looking are the operations that can be performed on a grinding machine.


The severity of the grinding operation affects the choice of abrasive and grade. A tough abrasive like 4A Aluminum Oxide should be used for rough, heavy duty grinding of steel. The milder abrasives like 32 and 38 Aluminum Oxide are best for lighter precision grinding operations on steels and semisteels, while the intermediate 57 and 19 Aluminum ...
