AI Technical Summary

Technical Problem

Axial errors in CNC machine tool spindles can cause product damage, and current technology lacks portable and effective error compensation mechanisms.

Method used

An axial error compensation mechanism for CNC machine tool spindles, including a monitoring mechanism, was designed. The monitoring mechanism consists of a mounting base, a vision monitoring head, and a transmission cable. It is connected to the control terminal through the transmission cable. The mounting base is fixed by locking bolts and buffer pads. The vision monitoring head is adjustable in angle to achieve convenient installation and error correction.

Benefits of technology

It enables portable spindle error compensation, reducing the labor intensity of machine tool operators and improving machining accuracy and product quality.
