Description

Technical Field

[0001] The utility model belongs to the technical field of drill bit shank material recovery, and relates to a cutting fixture for recovering PCB drill bit shank materials. Background Art

[0002] The drill bit is one of the indispensable tools in the production of PCB boards. By using the high-speed rotation of the drill bit to open holes in the PCB board, the production speed of the PCB board can be increased and the processing difficulty of the PCB board can be reduced. Generally, the carbide handle material and the drill bit part are welded to obtain a complete PCB drill bit.

[0003] After the existing PCB drill bit is used, the drill head will gradually wear out, resulting in damage to the PCB drill bit. However, the damaged PCB drill bit shank can still be reused. Therefore, the damaged drill head of the PCB drill bit will be cut off and the carbide shank will be recycled. The existing cutting device is difficult to control the cutting position of the PCB drill bit and the length of the shank, resulting in the need for secondary cutting correction of the shank. Therefore, we propose a cutting fixture for recycling PCB drill bit shank materials. Utility Model Content
