Dual grinding machines deliver a two-step process that combines centerless grinding with grinding between centers, alleviating concentricity concerns. In the Zone. Regardless of machine design, the workpiece is guided by its outer surface during centerless grinding. Because of this, roundness can be a concern, especially lobing and triangulation.
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.
A stop screw 89 threaded in a fixed part of the machine serves as a stop to limit the counterclockwise movement of the carrier and determine its grinding position.

Centerless grinding is a process which can produce workpieces with accurate cir-cular cross sections at high production rates. This study analyzes a form of centerless grinding called shoe-type centerless grinding where the workpiece is held between a …
A centerless grinding machine is used. In this machining, the periphery of a rotating cylindrical work material is ground using three parts: a fixed blade (support blade), a grinding wheel, and a rotating regulating wheel, without drilling a center hole in the work material.
For wide machines, coarse, medium and fine grit wheels can be combined. Very fine grit wheels are available. Stainless Steel - A Better Way . A type of centerless grinding that NT wheels handle very well is stainless steel. Stainless has always been a difficult family of steel to grind, especially the austenitic 300 series.
Centerless Grinding Machines. In centerless grinding, the workpiece is held between two grinding wheels, rotating in the same direction at different speeds. One grinding wheel is on a fixed axis and rotates so that the force applied to the workpiece is directed downward. This wheel usually performs the grinding action by having a higher linear ...
