Difference Between Fixtures and Jigs
The words fixtures and jigs are common terms used in machine shops. Although both are used as tools to mass-produce parts, they have two distinct functions.
Fixtures are used to hold work pieces in at specific location. For example when parts are machined on a machining center or wire EDM, they are clamped into a fixture which reduces the amount of set up time. This eliminates set up errors and brings down production cost. As all machine shops owners are aware of, the best machine tool is one that is making parts and not sitting idle. Fixtures need to be heavy and rigid, and machined with precision in order to have consistent results.
A jig is a tool that guides another tool in order to improve the accuracy of the part during machining. Often a jig is used in drilling, boring, and tapping operations so the drill doesn’t wobble or stray away from the location where it’s suppose to be. They are also used to make sure a part is drilled to a specified depth without the need constantly check and re-drill if needed.
