Custom Diaphragm Chuck for milling precision gears

Every week exciting new projects are heading out the door, such as this Custom Diaphragm Chuck for milling precision gears.

Brief: The customers work piece is a small precision gear that requires milling on one face, timed to existing geometry.

Challenge: The outer diameter of this gear could not be touched so it needed to be gripped on the root diameter.

Solution: A Northfield DPH-400 (.00050” T.I.R.) 4” diameter diaphragm chuck was provided, with sub jaws, changeable inserts and stops for different sized work pieces.

  • The inserts are wire cut to clear the major diameter and clamp on the root diameter.
  • Changeable stop pads have timing pins, to orient the work pieces prior to clamping.
  • The base stop has a ground indicating band for initial setup.
  • The chucks ‘pull-back clamping’ action ensures the part is seated flat.
