Jigs Fixtures – Definations and Importance?

Jigs and fixtures manufacturers in India offer different varieties of these tools. But what exactly are these and why are these needed? Anything that holds or aligns a component or a tool in the manufacturing process of fabrication or assembly is a jig or a fixture. So, basically, it’s a tool used in manufacturing, so as to produce work that is interchangeable within the tolerances set by manufacturing requirements. Now describing individually, a device that supports the workpiece is a jig. It holds the workpiece intact at the proper location using locators. It is basically a guide for the cutting tool ensuring the operation is smoothly done at the right place. It is used in drilling and reaming operations. Fitted with hardened steel bushings, jigs are used for guiding the cutting tool. Jigs may be fastened or not fastened to the working table. The jig may not be fastened to the machine, on which it is used, for the smaller size of the cutting tool. While drilling multiple holes on th

Jigs and Fixture – Work Holding Devices

Jigs are basically work-holding devices. They hold, locate, and support the work piece and guide one or more tools to perform a specific operation. In short, jigs hold the tools and guides the cutting tools. Hardened steel bushings fitted on jigs are for guiding or other cutting tools. It is actually the tool to control the location and motion of another tool. A jig's primary purpose is to provide repeatability, accuracy, and interchangeability in the manufacturing of products. A device that does both functions of holding the work and guiding a tool is called a jig. To explain jig as a layman, take an example of a lost key rebuilt with the help of a duplicate key that is a jig. The fixture is also a work-holding device that holds, supports, and locates the work piece but does not guide the cutting tool. It offers only a reference surface or a device for operation. So, Jigs and fixtures are production tools used to accurately manufacture duplicate and interchangeable parts. Jigs and
