Reduced grinding allowance: During centerless grinding, the machining process starts with the workpiece finding its rotational axis based on its existing shell surface. Because the highest points on the workpiece are the first to be touched, centerless grinding involves the largest diameter in the current state being ground to completion.

Advantages of Centerless Grinding. High level of automation – saving time and maximising productivity.; Short set-up times, hence flexible.; Accurate: small tolerances achievable; because the positioning inaccuracy of the grinding disc to the control disc is half with respect to the positioning of the grinding disc during circular grinding.
Basically there are three different methods by which centreless grinding can be done on different types of jobs. Method # 1. Through-Feed: This is simplest method and is applied only to plain parallel parts such as roller pins and straight long bars which are difficult to grind by ordinary cylindrical grinding …
Centerless Grinders. For fast stock removal, lower machine tolerances and size as low as 0.0001″ or better, centerless grinding is the answer. Fortunately, centerless grinding has grown in popularity in the sphere of grinding technology. With centerless grinders, as the name implies, the work is not supported between centers.
Centerless grinding, as the name implies, is a process that grinds the surface of a turned part or round bar of material, without the need to support the work piece on centers.
