Description

Technical Field

[0002] During the production process of rod-shaped metal parts with protrusions at both ends, the middle part of the rod-shaped metal parts needs to be ground with the help of a centerless grinder. A centerless grinder is a grinder that does not require the axis of the workpiece to be positioned for grinding. It mainly consists of three mechanisms: a grinding wheel, an adjusting wheel, and a workpiece support. The grinding wheel is responsible for the actual grinding work, the adjusting wheel controls the rotation and feed speed of the workpiece, and the workpiece support supports the workpiece during grinding.

[0003] In the process of grinding rod-shaped metal parts, the operator usually holds the end of the metal part and then grinds the metal part. During the grinding process, the operator manually feeds the metal part. The operator usually wears gloves when working. If the operator has insufficient work experience or the position of the hand is not accurate, the hand is easy to stick to the grinding wheel. The surface of the grinding wheel is relatively rough, and the operator's hand is easy to be rolled away by the grinding wheel, which leads to production accidents.
