APPLICATIONS OF JIGS AND FIXTURES

Jigs and Fixtures are typically used for machining operations. The other operations as assembly, inspection, lay out and testing are the areas where holding devices are suited well.

MODULAR FIXTURES:

Many advantages can be achieved of a permanent tool with the help of a temporary set up. The combined ideas of work holders and elements of permanent and general purpose work holding is used in the tool application. The modular work holders combine the temporary and permanent work holding to make and inexpensive work with high durability. The main advantages with modular fixtures are durability, setup reduction, improvement in productivity, reduced decision making in operation selected from the standard components. The fixture can be dis assembled after its usage and can be reused again for other purpose. This re-usage enables the construction of high precision and more complex tools without the dedication of the corresponding fixture components.
