AI Technical Summary

Technical Problem

The existing rotary table's structural design leads to machining errors and vibration problems, affecting machining accuracy. Furthermore, the operating errors of the clamping equipment cause imbalance, making it difficult to achieve high-precision machining.

Method used

The rotary table design includes a base, turntable, bearings, rotary drive, and linear drive. By combining rotation and linear motion, the assembly thickness of the base and turntable is reduced, ensuring machining accuracy and stability.

Benefits of technology

By combining the motion of rotary and linear actuators, the assembly thickness of the base and turntable is reduced, improving machining accuracy and structural rigidity, reducing errors and vibrations, and enhancing machining stability.
