AI Technical Summary

Technical Problem

Existing polishing rods cannot be easily separated from the grinding head, so the entire rod needs to be replaced when the grinding head wears out, increasing the cost of use and the frequency of replacement.

Method used

The polishing rod body and grinding head assembly are easily separated by using internal hex screws and threaded holes, combined with adhesive, allowing for convenient disassembly and replacement of only worn parts.

Benefits of technology

This allows for easy separation of the grinding head assembly and the polishing rod, reducing maintenance and replacement costs and improving product maintenance efficiency.
