AI Technical Summary

Technical Problem

Most existing carbide cutting tools have a single-sided cutting structure, resulting in a short service life. Frequent replacements increase processing costs and reduce efficiency.

Method used

A CBN carbide blade with a double-sided cutting structure is designed. Through the cooperation of components such as mounting base, rotating base, rotary table, sliding groove, slider, insertion rod, spring, and pull block, the position and angle of the blade can be flexibly adjusted, and the wear resistance is improved by titanium nitride coating.

Benefits of technology

This improves the lifespan and processing adaptability of the blades, reduces the replacement frequency, and increases the practicality and stability of the equipment.
