Our founder started out with jig grinding services in 1960 to other job shops. Since then Superior Jig, Inc. has added toolmaking, jig and fixture making, custom gages, CNC machining, multi-axis machining, wire and conventional EDM, and related assemblies. With these capabilities located at one facility, we can make your design quickly, accurately and competitively.
We specialize manufacturing assemblies, newly designed, pre-production, engineering models, tight tolerance, thin walled, low or high quantity or difficult to make.
