Basics of Grinding Fundamental Manufacturing Processes Video Series Study Guide - 3 - 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.
Centerless grinding is often viewed as overly complex, but a look at the process' fundamentals reveals otherwise. Cinetic Landis . ... which can cause profile problems. To prevent that, the blade is reground to the desired angle and flatness. Shims can be used to adjust blade height, but other methods are avail-
Centerless grinding is an OD grinding process. It differs from other cylindrical processes in that the work-piece is not mechanically constrained. Centerless grinding is used to achieve roundness, surface finish and dimensional tolerances that are among the best available in metalworking. +/- .0001" is typical
In thrufeed centerless OD grinding the workpiece passes between two wheels, a grinding wheel and a regulating wheel (as illustrated in the diagram, right). Both wheels rotate in the same direction, but at much different speeds. The purpose of the grinding wheel is to remove material from the workpiece and improve part OD quality.
