Eight principles of centerless grinding, number three

3. Grinding methods vary in the way parts pass through the machine.

The main difference between the two most common centerless grinding methods is how the workpiece is fed through the machine tool.

Through-feed grinding is usually used for parts with uniform roundness throughout the length of the part. In this method, the workpiece travels along the remaining blades between the two wheels.

The workpiece is basically "squeezed" onto the grinding wheel and out of the other side by the feed method, driven by a slight Angle applied to the regulating wheel relative to the grinding wheel.

Feed internal grinding (also known as plunge grinding -- used to grind outer circular parts with notches or complex shapes, such as gear shafts). Here, the workpiece fixture needs to be machined to match the shape of the part, and the grinding and adjustment wheels must be trimmed to match the profile cutting required for the part.

Using the feed method, the regulating wheel rotates the part at one speed while pushing it toward a grinding wheel that rotates at a faster speed. The greater the velocity difference, the faster the removal rate.
