[0002] A centerless grinder is a type of grinder that does not require the axis of the workpiece to be positioned for grinding. It is mainly composed of three mechanisms: a grinding wheel, an adjusting wheel, and a workpiece holder. The grinding wheel is actually responsible for grinding, the adjusting wheel controls the rotation of the workpiece and the feed speed of the workpiece, and the workpiece holder supports the workpiece during grinding. These three parts can be coordinated in several ways, but the principles are the same except for stopping grinding.

[0003] When the existing three-unit centerless grinder is in use, when loading pipes, the staff usually manually move the pipes to the transport chamber of the centerless grinder for loading. This method is more troublesome, and the number of processed pipes cannot be recorded during loading.
