Common Centerless Grinding Methods

Centerless grinding method is also called centerless cylindrical grinding method, there are three common grinding methods, pass-through, plunge-cut and plunge-through.

1. Pass-through centerless grinding is also called through-type grinding. The workpiece is fed along the grinding wheel axis, and the guide wheel axis is adjusted to realize the axial feed of the workpiece. It is suitable for grinding slender cylindrical workpieces, short shafts without center holes and sets of workpieces.
2. Plunge-cut centerless grinding. There is an axial positioning pivot point on the pallet, and the workpiece is supported on the pallet at a certain position, and the grinding wheel or guide wheel is cut in for grinding. It is used for grinding workpieces with shoulders or cams as well as cones, spheres or other rotating workpieces.
3. In addition, there are also tangential feed grinding and end-feed grinding where the workpiece with a step is fed in and out axially.

Advantages of Centerless Grinding:

1. It can realize the processing of large quantities of workpieces and save time.
2. High efficiency of centerless grinding improves productivity.
3. Good rigidity of processed parts, easy to realize high-speed grinding and powerful grinding.
4. It can be used for complex surface grinding or multi-grinding wheel grinding, with a wide range of applications.
5. It can ensure the precision and surface finish of the parts and reduce the wear of grinding wheel.
6. High rigidity ensures the best precision of grinding, high productivity and large grinding allowance.

Common centerless grinding wheels are diamond grinding wheels (diamond and CBN) and adventional grinding wheels.
