Different types of substrates are produced according to the cutting requirements using high quality domestic tool steel plates, Japanese special steel plates and German special steel plates. The design of substrate structure can be in the form of silencing, composite, conventional, etc., which has the characteristics of improving the operating environment, increasing the stability of product operation and reducing frictional heat. The cutter head adopts Japanese and German carbide or cermet materials, and the surface layer of the alloy is hardened (coated) to increase wear resistance and extend the cutting life. The cutting surface is smooth and flat, without bevel, ensuring high precision and less burr at the cutting part, effectively improving the production efficiency. Can be repaired and reused.
