[0002] Chamfering refers to the process of cutting the edges and corners of a workpiece into a certain slope. Chamfering is to remove burrs on the parts caused by machining and to facilitate the assembly of parts. Generally, chamfering is done on the ends of the parts. The general function of chamfering is to remove burrs and make them beautiful.

However, this structure can only grind flat hardware accessories. Another arc grinding technology meets the requirements. This technology drives the adjusting screw to rotate, thereby driving the slider to slide on the adjusting screw. The slider pulls the supporting plate through the second connecting rod. Since the supporting plate can slide on the first connecting rod through the sliding sleeve, it can drive the supporting plate to move in an arc, which is beneficial for the grinding block to grind the arc surface of the hardware, but the arc surface angle of the hardware accessories is fixed.
