Research on Wear Mechanism of Self-Sharpening Fine Super-Hard Abrasive Tool

Abstract:

To achieve the components of the highest quality in terms of shape, dimension, surface integrity and high efficiency in the course of processing difficult-to-cut material, the concept of self-sharpening fine super-hard abrasive tool as machining tool is put forward, this method not only improves the dressing performance of the abrasive tool, but also ensures the accuracy and durability of the abrasive tool, self-sharpening fine super-hard abrasive tool lapping technology is developed by using Zn as abrasive fillers and using FeCl₃ solution as lapping liquid, the wear form of the self-sharpening fine super-hard abrasive tool and the influence of abrasive wear on the material removal form is studied, research shows that the wear of the self-sharpening fine super-hard abrasive tool is mainly in breakage wear, which has a good self-sharpening performance, and the material removal form is mainly in two-body material removal mode., which means this method has good holding force of abrasives.
