There are three main grinding methods for centerless cylindrical grinders; Through type, cut in type, and cut in one through type

Through type centerless grinding. The workpiece is fed along the axis direction of the grinding wheel for grinding. Adjust the small inclination angle of the guide wheel axis to achieve axial feed of the workpiece. Suitable for grinding slender cylindrical workpieces. Short shafts and sleeve type workpieces without central holes.

Cut in centerless grinding. There is an axial positioning fulcrum on the pallet, and the workpiece is supported at a certain position on the pallet for grinding with a grinding wheel or guide wheel. Used for grinding workpieces with shaft shoulders or bosses, as well as conical, spherical, or other rotating workpieces.

One through type centerless grinding is a combination of these two. In addition, there are tangent feed grinding and end face feed grinding that allows stepped workpieces to advance and retreat in the axial direction. The productivity of the centerless cylindrical grinder is relatively high. Mostly used for mass production and easy to achieve automation.

Characteristics of Centerless Grinding machines：

1. Continuous processing, no need for tool return, short replication time for workpiece clamping, and high productivity.

2. The positioning mechanism of the bracket and guide wheel has better support rigidity than the top and center frame mechanisms of ordinary cylindrical grinders, with a larger cutting amount, and is conducive to the processing of slender shaft workpieces, making it easy to achieve high-speed grinding and strong grinding.

3. The workpiece of the centerless cylindrical grinder is positioned on the positioning mechanism by the outer circle, and the grinding amount is the margin on the diameter of the workpiece. Therefore, the wear of the grinding wheel, the compensation of the feed mechanism, and the repeated positioning accuracy error of the cutting mechanism have an impact on the diameter and size accuracy of the part. It is only half of a regular cylindrical grinder, does not require a center hole, and is easy to automate loading and unloading in advance.

Centerless Grinding machines is a type of grinder that does not require the use of the axis of the workpiece for grinding. It generally consists of a grinding wheel, a guide wheel, and a bed. The grinding wheel and guide wheel are installed on the bed, and the grinding wheel actually performs the grinding work.
