The existing treatment method is to remove the burrs at the edges and in the holes by stamping with a stamping machine. However, due to the diverse shapes and sizes of door lock panels, specific fixtures are required to clamp them during stamping on the stamping machine. This makes it necessary to customize and install fixtures for each type of lock panel, increasing the production cost.
