Description

Technical Field

[0001] The invention belongs to the technical field of milling cutter production and relates to an adjusting device for surface treatment of a PCB milling cutter. Background Art

[0002] The milling cutter used for PCB is also called a milling cutter. It is used in the post-process of PCB (or pressing and catching the outer frame). The main purpose is to use this tool to cut the manufactured circuit board into separate PCS or SPNL and then ship it to the customer. This tool is mainly used for cutting. The blade and the force direction are horizontal, similar to a drill needle, but the force and cutting direction of the drill needle are at the drill tip. There are two types of milling cutters: fishtail type and drill tip type. The special design focuses on the service life of the milling cutter and the chip removal effect. Its characteristics are large chip grooves, which make chip removal smooth during drilling, low heat generation, and less stains on the hole wall.

[0003] During the production of existing PCB milling cutters, it is necessary to grind and polish their surfaces from different angles. Generally, the PCB milling cutter is fixed at a certain angle, and a grinding device grinds the surface of the PCB milling cutter. After the grinding is completed, the fixed angle of the PCB milling cutter needs to be adjusted again, which requires manual adjustment. In addition, the adjustment step greatly slows down the speed of PCB milling cutter surface polishing and reduces the efficiency of PCB milling cutter surface polishing. Therefore, we propose an efficient adjustment device for PCB milling cutter surface treatment. Summary of the invention
