It is mainly used for the production of instruments, watch parts, automobiles, machine tools and other various machines with small force and strict requirements on size and finish. It requires strict dimensional accuracy and smoothness, and relatively low mechanical performance. Standard parts such as gears, shafts, bolts, valves, bushings, pins, fittings, spring seat cushions and machine screws, plastic molding dies, surgical and dental surgical instruments.
