Precision Diaphragm Chucks for Clamping
Northfield Precision Instrument Corporation is a leader in the design and manufacture of precision workholding air and diaphragm chucks. Northfield manufactures precision air chucks with a guarantee of accuracy within millionths. Northfield is pleased to announce it's new Special 5" Diaphragm Chuck for clamping applications.
Model DPS-5s is a special 5 inch diameter chuck, air open diaphragm clamp. Chuck has 8 sets of jaws that repeat to 1/10,000 when removed and replaced. Six different stops mount to center of chuck for positive axial location. Jaws are alloy steel hardened to 58/63 Rockwell "C". Chuck is mounted to a special balance machine that finds the center of gravity of the cast turbine blades and drills a centering hole in that position. The part is now rotated about this center instead of machining weight off different areas for balance. T.I.R. = 50 millionths, Axial = 0, cycle time 30 seconds.
In addition to Diaphragm Chuck Model DPS-5s we are pleased to introduce our Special 7" chuck for C.V. clamping. This counterbalanced diaphragm chuck has 3 pull down fingers. Jaws grip O.D. of C.V. joint while fingers pull it into the fixed axial stop for zero axial location. Chuck rotates 5 - 6,000rpm to balance C.V. joint driveshafts, T.I.R. = 50 millionths, Axial = 0, Cycle time 60 sec.
