In the machining process, as the tool cuts off the unnecessary material from the workpiece, a cutting force will be generated on the workpiece. To resist the cutting force and allow the cutting process to be completed, the workpiece must be firmly clamped on the machine tool. The device that positions and clamps the workpiece is called a fixture. The device that holds and guides the cutting tool is called jigs.

What are Jigs?
Unlike the fixture which holds the workpiece in a fixed position, the jig is a tool that assists in controlling the position or action of a cutting tool as it machines a workpiece that has been positioned in a predefined location. Jigs are used for controlling tools for woodworking, metalworking, manufacturing, handicrafts, and other applications. They allow for smooth manufacturing operations, shorten the processing times, and increase productivity.

One of our customer uses the Spanclamps quarter trurn to built JIGS for workpieces.
