Although the aforementioned tool grinders allow users to repair damaged tools by themselves, they are highly praised. However, current tool grinders are designed with a fixed angle, so they cannot be used to grind and repair a chamfering knife. The knife surface gradually expands toward the direction of the tool shaft around its central axis, and then gradually shrinks after passing the center point, forming a tapered surface of unequal width. Therefore, the creator of this case is observing the shortcomings of the existing grinder Later, I thought how to develop a grinding machine that can grind and repair chamfer knives is really necessary, and this creation came into being.
