This kind of blades are specially used in high speed slitting machine line, which are suitable for processing CRC( cold rolled coil), HRC (hot rolled coil), acid steel sheet, silicon steel sheet, stainless stell, silicon steel slice and steel strip etc The slitting and cutting is the really important statge in the whole steel coil processing, therefore, that request really high precision on the blades, the surface of the blade is smithed, machined, through heat treatment and it specially grinded by high precision grinding machine while a strict quality and inspection control is perforamnce to ensure the parallelism to lerance of finished products is within 0.003mm
