Diaphragm turning chuck DPH-5S

automatic6-jawclamp

Special 5-inch diameter diaphragm chuck, air- open diaphragm clamp. Chuck has 8 sets of jaws that repeat to 1/10,000 when removed and replaced. Six (6) different stops mount to center of chuck for positive axial location. Jaws are alloy steel hardened to 58/63 Rockwell “C.” Chuck is counter 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
