Punching disc punching was developed for the early use of brake pads, and today, with the change of brake pad materials, punching treatment is no longer necessary. Why aren't there more holes in the brake discs?
Because there are some drawbacks to brake disc drilling:
1, the disk surface punching, the overall strength of the brake disc will be reduced, affecting the braking effect.
2, after the punching treatment, the friction area of the brake disc is reduced, and the friction will have a certain loss.
3, after drilling, the heat conduction area of the plate surface is reduced.
4, after the brake disc punching treatment is used for a period of time, there will be fine cracks around the ventilation hole, and even deformation and jitter.
In short, there are some drawbacks in the brake disc punching treatment, so now the brake disc punching is not much, by changing the material of the brake disc, you can solve the needs of the brake disc punching treatment, and the product still has a good brake use effect.
