Applications of Thread Rolling

Applications of Thread Rolling - Thread rolling is an economical, chipless, cold forming process principally used to make external forms on cylindrical workpieces. The process has long been used by the fastener industry to produce smooth, precision threads at high production rates.

More recently, a wide variety of other applications have been found for this process, particularly as a profitable method of forming other external cylindrical shapes, such as gear teeth, splines, and various forms of knurl patterns and serrations. Fig. illustrates typical sample parts, which bring out the versatility of parts adaptable to this process.

Typical Sample parts Made by Thread Rolling

As a general rule, plain carbon steels, structural alloy steels, high speed steels, nonleaded brasses, and copper constitute the majority of materials used in rolling threads and other external forms on parts. Selection of materials often depends upon an optimum combination of rollability and machinability of the material.
