High Efficiency Tools of machining Centrifugal Composite HSS
Centrifugal composite HSS roll has high core toughness, high strength working layer, high wear resistance characteristics, is widely used in narrow strip, bar and other production lines. However, due to the constraints of the existing machining level, high-speed steel roll processing efficiency is very low, the application of performance is not high, less output, limiting its popularity. Through the production practice, the engineer research new methods with high efficiency with the help of new materials, cutting tools, machining process improvement, and on the basis of strong cutting principle, which help realize the efficiency greatly improved of processing the HSS steel rolls.
The cutting tools of processing HSS rolls with high efficiency
In China, we use CNC Lathe to machine HSS Rolls, the cutting speed is small and the cutting force also small, so it doesn’t required high on the rigidity of the lathe. And it has high processing precision, but low efficiency, and the costs are very high.
High Efficiency Processing is based on the strong cutting force, both the cutting amount and the cutting force is large, it needs to use heavy duty CNC mills to machine. The cutter body use HSS materials, and the insert we choose special grade BN-S20 solid cbn insert, which has excellent performance on machining HSS rolls. The tools strength and the red hardness are the important factors that we need to consider when choose cutting tools for high speed machining HSS Rolls.
High - speed steel roll processing technology
High-speed steel roll processing is to increase the amount of cutting, reducing the number of machining steps to achieve. Therefore, machining technology and the cutting amount is based on the strong cutting force.
The following is one application case of machining HSS Rolls for reference.
