Applications for Jigs & Fixtures

Typically, the jigs and fixtures found in a machine shop are for machining operations. Other operations, however, such as assembly, inspection, testing, and layout, are also areas where workholding devices are well suited. The list below shows some of the more common classifications and applications of jigs and fixtures used for manufacturing. There are many distinct variations within each general classification, and many workholders are actually combinations of two or more of the classifications shown below. 

EXTERNAL-MACHINING APPLICATIONS:

  • Flat-Surface Machining
  • Milling fixtures
  • Surface-grinding fixtures
  • Planing fixtures
  • Shaping fixtures

Cylindrical-Surface Machining

  • Lathe fixtures
  • Cylindrical-grinding fixtures

Irregular-Surface Machining

  • Band-sawing fixtures
  • External-broaching fixtures

 

INTERNAL-MACHINING APPLICATIONS:

Cylindrical- and Irregular-Hole Machining

  • Drill jigs
  • Boring jigs
  • Electrical-discharge-machining fixtures
  • Punching fixtures
  • Internal-broaching fixtures

 

NON-MACHINING APPLICATIONS:

Assembly

  • Welding fixtures
  • Mechanical-assembly fixtures (Riveting, stapling, stitching, pinning, etc.)
  • Soldering fixtures

Inspection

  • Mechnical-inspection fixtures
  • Optical-inspection fixtures
  • Electronic-inspection fixtures

Finishing

  • Painting fixtures
  • Plating fixtures
  • Polishing fixtures
  • Lapping fixtures
  • Honing fixtures

Miscellaneous

  • Layout templates
  • Testing fixtures
  • Heat-treating fixtures
