1. Initial wear stage
The cutting process of the cutting tool of the Honggang Cutting Machine is fast and the time is short. The sharpening of the surface of a newly sharpened tool is prominent. During the friction with the chips, the pressure is not uniform, and the pressure at the peak is very large, causing the peak to be quickly worn away so that the pressure tends to be even and the wear speed is slowed down.
2. Normal wear stage
The surface of the cutter of the Honggang cutting machine is initially worn, the peak point is smoothed, the pressure of the surface tends to be even, and the wear amount VB of the tool increases evenly with time. The wear curve at this stage is basically linear, and its slope represents the wear strength, which is an important indicator for comparing tool performance.
3. Rapid wear stage
After the normal wear stage of the cutting tool of Honggang Cutting Machine, the cutting edge has become dull, the cutting force and cutting temperature rise sharply, the cause of wear changes qualitatively, the surface of the tool is fatigued, the performance is degraded, the wear amount VB increases sharply, and the tool will be very fast. Invalid.
