In the process of mechanical manufacturing, it is often necessary to chamfer the corners of the workpiece. The so-called chamfering is to remove the edge part at the corner to form an arc transition, which makes the workpiece smoother and more beautiful and reduces the probability of damage to the workpiece due to the protruding corner. In mechanical chamfering, chamfering knife or grinding head is generally used to process edges and corners, which requires special processing equipment and technology, so it is a common mechanical processing method.

Chamfering methods are mainly divided into manual chamfering and mechanical chamfering. Manual chamfering is a manual operation, which requires workers to process corners one by one with hand tools, which is inefficient and difficult to control. Mechanical chamfering adopts advanced mechanical equipment and automatic tools, which can quickly and accurately process the angular parts of the workpiece with good processing quality and high work efficiency. At present, mechanical chamfering has become the mainstream method of chamfering.

Chamfering treatment is a common process in machining, which is suitable for angle treatment of various materials, such as metal, plastic and ceramics. Chamfering can not only improve the aesthetics of the workpiece, but also increase the service life of the workpiece and reduce the faults caused by edge damage, so it is widely used in industrial fields such as machinery manufacturing, automobile manufacturing and electronic manufacturing. At the same time, in daily life, chamfering treatment is also widely used in ceramic tile corners of bathrooms, desks and chairs in offices, and so on.
