AI Technical Summary

Technical Problem

During the machining process, metal chips fly up and accumulate on the inner wall of the equipment housing of existing CNC machine tools that perform milling and turning operations, making cleaning difficult and affecting the service life of the equipment.

Method used

A scraper is installed at the top of the inner wall of the CNC machine tool housing. A lifting rod is driven by a forward and reverse motor gear. With the help of a limit groove and a guide sleeve, the scraper can be raised and lowered for cleaning. Metal chips are collected in a drop trough and a collection trough.

Benefits of technology

It achieves efficient cleaning of the inner wall of the chamber, avoids the accumulation of metal shavings, and extends the service life of the equipment.
