Grinding collet chuck

pneumatic

Special “Two Stage” internal grip collet chucks. These chucks hold transmission gears for face grinding. The customer required that the chucks “first” grip the part, then pull it back 1.5mm onto an air-detect part-stop. The chucks are air-open and spring-clamped. Changeable collets and air-detect stops run over 13 different part sizes. Running 24/7 with a 45-second machine cycle, these chucks come back to Northfield once a year for cleaning and seal changes. Chuck diameter is 6.5-inches.
