Which is more accurate, centerless grinding or cylindrical grinding? What's the difference between them?

The precision of centerless grinding is higher than that of cylindrical grinding.

First, refer to different

1, cylindrical grinding: cylindrical grinding? It is mainly used for grinding the excircle, outer conical surface and shoulder end face of shaft workpieces on the excircle grinder.

2. Centerless grinding: it is a kind of grinding. There are two grinding wheels, a guide wheel and a grinding wheel. The guide wheel drives the cylindrical workpiece to rotate on the shim, and the grinding wheel grinds the workpiece.

Second, the principle is different.

1. Cylindrical grinding: During grinding, the workpiece rotates at a low speed. If the workpiece moves longitudinally back and forth at the same time, the grinding wheel moves transversely relative to the workpiece after each single stroke or double stroke of longitudinal movement.

2. Centerless grinding: it consists of three mechanisms: grinding wheel, adjusting wheel and workpiece support (bracket), in which the grinding wheel actually performs grinding work, and the adjusting wheel controls the rotation of the workpiece to make the workpiece feed speed. As for the workpiece support that supports the workpiece during grinding, there are several ways to cooperate with these three parts, but the principle is the same except stopping grinding.

Third, the characteristics are different.

1, cylindrical grinding: cylindrical grinding? It is mainly used for grinding the excircle, outer conical surface and shoulder end face of shaft workpieces on the excircle grinder.

2. Centerless grinding: the grinding wheel frame is fixed on the centerless cylindrical grinder. The grinding wheel frame of this centerless grinder is fixed on the lathe bed, and the guide wheel and the bracket can move relatively. When grinding or cutting, the guide wheel, the bracket and the workpiece do feeding and compensation movements together.
