Fuel injection needle

Application:

A fuel injection component is ground on a CNC OD grinding machine. The part is automatically loaded into the chuck, and must be ejected after the grinding operation is complete.

Required accuracy: 0,0025 mm TIR

Solution:

MicroCentric supplied a air chuck with a sealed rubber cover to prevent grinding grit and contaminants from hindering the chuck's accuracy and long term performance. The chuck included hardened top jaws and a special centre housing with a spring plunger to eject the workpiece as the chuck is unclamped.

Achieved accuracy: 0,0015 mm

Technology: APC-R
