AI Technical Summary

Technical Problem

The existing guide rail structure suffers from slight thermal deformation due to heat accumulation during operation, which affects the sliding accuracy of the slide and the service life of the guide rail.

Method used

It adopts a composite guide rail structure with a large span stepped sliding and steel-lined rolling elements, combining the load-bearing steel-lined guide rail and the load-bearing rolling elements. Active heat dissipation is achieved by controlling the air intake pump and solenoid valve through grating sensors, and heat dissipation vents are set between the load-bearing rolling elements for gas heat dissipation.

Benefits of technology

This effectively avoids minor deformations caused by heat changes, ensuring stable operation and processing accuracy of the slide plate, and extending the service life of the guide rail.
