Description

Technical Field

[0002] A centerless grinder is a type of grinder that does not require the workpiece's axis 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 actually performs the grinding work, the adjusting wheel controls the workpiece's rotation and feed speed, and the workpiece holder supports the workpiece during grinding. These three components can be coordinated in several ways, but with the exception of stopping grinding, the principles are the same.

[0003] A Chinese patent application, publication number CN217750699U, discloses a centerless grinder with an improved adjusting wheel. The grinder comprises a grinding mechanism and an adjusting wheel mechanism positioned above the grinding mechanism. The grinding mechanism and adjusting wheel mechanism are aligned horizontally. An adjusting wheel shaft is provided on one side of the adjusting wheel mechanism. The output shaft of the adjusting wheel motor is fixedly mounted on the adjusting wheel shaft through a key hole. Several adjusting wheels are sleeved onto the adjusting wheel shaft. The centerless grinder with an improved adjusting wheel comprises a dovetail key, a stop block, and an adjusting wheel. When grinding workpieces of different diameters, the screws on the stop block can be removed, the dovetail key can be removed, and an adjusting wheel of the appropriate size can be replaced and sleeved onto the adjusting wheel shaft.
