Machining - Material removal processes

The most common abrasive machining process is grinding, in which the cutting tool is abrasive grains bonded into a wheel that rotates against the workpiece. Grinding may be performed on a surface grinding machine which feeds the workpiece into the cutting tool, or a cylindrical grinding machine which rotates the workpiece as the cutting tool ...

Basics of Grinding - Stanford University

different internal contours can be produced within a workpiece using I.D. grinding. In centerless grinding, the workpiece rotates between a grinding wheel and a regulating drive wheel. The work is supported from below by a fixed work-rest blade. The two basic modes of centerless grinding are "thru-feed" and "in-feed" or "plunge" mode.

Basics of centerless grinding | Cutting Tool Engineering

During grinding, the force of the grinding wheel pushes the workpiece into the regulating wheel and against the support. The regulating wheel determines the workpiece's rotational speed. Tilt it a few degrees and the workpiece will be pulled through the wheels and out the back of the machine, a technique known as through-feed grinding.

What is Electrochemical Grinding and How it Works

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.

A road map for grinding and finishing stainless steel

Quite often workpiece surfaces designed with manufacturability in mind do not require both grinding and finishing. Parts that undergo only grinding do so because grinding is the fastest way to remove a weld or other material, and the deep scratches left by the grinding wheel fall well within customer requirements.
