From Roll Milling to Wind Turbines Halnn's Heavy Duty CBN Inserts As a high load and high requirement cutting method, Heavy duty cutting characterized by cutting speeds above 38m/min, AP of 10mm or more, and feed rate of 0.5mm/r or more. Compared to normal machining, heavy duty cutting has a greater cutting depth, lower cutting speed, and slower feed rate.
In heavy duty cutting processes, vibration caused by poor workpiece balance, uneven distribution of machining allowance, and imbalance of certain components of the lathe during the cutting process requires a large amount of maneuvering and auxiliary time for the dynamic imbalance process of machining. Compared with ordinary turning tools, heavy cutting requires a larger cutting amount, and there are significant differences in working conditions and tool clamping methods. Therefore, tool design has its own significant characteristics in heavy duty cutting. Io address the problems that arise during heavy cutting, more suitable materials, new design of chip breaker, and geometry solutions are developed by Halnn. Rolling mill industry: Our Heavy-duty series full face PCBN(RCGX) tools have a fine performance on machining rolls.
The ceramic binders are adopted instead of
metal binders such as aluminum and cobalt, allowing the tools get better performance under classic heavy-duty working condition such as long-term, high cutting force, and high cutting temperature.
