Customer Brief

Our customer is a heavy duty fuel pump and injector systems manufacturer. They requested a method to accurately grip their small (.098” OD) fuel injector plungers without marking them.

Challenge

The tip of their part must rest in a carbide seat, ground central to the chuck. This requires the special part stop.

Northfield Solution

The jaws are made from a special, highly abrasion-resistant, engineered plastic. Designed to withstand repeated clamping with minimum wear. The bore diameter gripping the part yields an accuracy and repeatability of more than 50millionths” TIR total runout to the chuck’s center line.
