Indexing and positioning equipment sets up parts and workpieces for layout, inspection, and machining. Plungers install through a table or fixture to locate and position parts. Plungers extend to align the part and retract to move the part. Locating pins are unthreaded to quickly install in and remove from a fixture for reuse. Positioning feet stop parts to ensure they're placed in the same place for repeated machining. Positioning grippers have serrated or nonslip surfaces to prevent parts from shifting.
