AI Technical Summary

Technical Problem

Traditional CNC indexing plates use a single braking structure, which leads to uneven wear of the friction plates and reduced braking efficiency, affecting service life and machining accuracy.

Method used

It adopts a dual braking structure. The movable arm driven by the fixed bracket and hydraulic cylinder drives the friction pads to approach the brake disc from both sides simultaneously for braking. Combined with the hydraulic oil system and return spring, it realizes reliable clamping and heat dissipation of the friction pads.

Benefits of technology

This reduces the contact friction between the friction pads and the brake disc, avoids uneven wear, improves service life, and effectively disperses heat, ensuring braking performance and continuous, efficient operation of the equipment.
