SUM24L cutting steel Usage:

Mainly for the production of a smaller force size and finish requirements strict instrumentation, watch parts, automotive, machine tool and

Other machine, strictly on the dimensional accuracy and surface finish requirements, while relatively low mechanical performance requirements of standard parts

, Such as gears, shafts, bolts, valves, bushings, pins, pipe joint, the spring seat and the machine screw, plastic molding mold, the outer

Branch and other dental procedures appliances cutting of the products subject to the secondary processing such as cutting resistance, information, precision, communication, 3C appliances

Processing the universal cutting materials.
