Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of polishing device, specifically relates to a polishing device for numerical control punch press. BACKGROUND

[0002] The cutting edge of the punch die will gradually wear and blunt during use, resulting in a decrease in the size and precision of the punched part, accompanied by the appearance of burrs. The polishing device for numerical control punch press is specially used for polishing the die of the numerical control punch press. Through polishing, the sharp punching edge of the die can be restored, the punching burr can be reduced, and the size and geometric position precision of the punched part can be improved.

[0003] The punch die is divided into a punching die and other types of dies.
