Service life management method for circuit board drill bit

The invention discloses a service life management method of a circuit board drill bit, which comprises the following steps: on one hand, dividing the drill bit into four stages, drilling a soft circuit board and a hard circuit board by using drill bits in different stages, on the other hand, grinding and maintaining the drill bit according to the use times of the drill bit, and classifying the drill bits in the four stages according to the grinding and maintaining times; the drilling thickness of the drill bit in each stage is set according to the abrasion degree of the drill bit in each stage, the service life of the drill bit is further prolonged, meanwhile, the drill bits in the four stages are installed on four drilling machines respectively, and the problem that the production efficiency is reduced due to replacement of the drill bits is solved. 本发明公开了一种电路板钻咀的寿命管理方法，一方面将钻咀分为四个阶段，针对电路软板和电路硬板使用不同阶段的钻咀进行钻孔，另一方面根据钻咀的使用次数来对钻咀进行研磨保养，根据研磨保养的次数来分类四个阶段的钻咀；根据每个阶段钻咀的磨损程度设定了每个阶段钻咀的钻孔厚度，进一步提高钻咀的使用寿命，同时将四个阶段钻咀分别装于四个钻机
