[0002] At present, the automobile industry is in a stage of rapid development, so the demand for brake discs is also relatively large. Since brake discs play a key role in automobile braking, the quality of brake discs will affect the braking effect and the safety factor of the car to a certain extent. The brake disc is connected to the car through a fixed screw hole, and it also rotates when the car is moving. The brake caliper clamps the brake disc to generate braking force. When you step on the brake, it clamps the brake disc to slow down or stop the car.
[0003] When drilling holes in brake discs, most of the time, a drill is used to drill holes in the brake discs one by one, which consumes a lot of time and greatly reduces the drilling efficiency. Moreover, after each hole in the brake disc is drilled, the staff needs to make multiple adjustments to remove and place the brake disc, which greatly increases the work intensity of the staff and reduces the loading and unloading efficiency of the brake disc.
