JP SERIES HIGH SPEED DIAPHRAGM CHUCKIdeal for fragile parts, or thin-wall parts clamping.
JP/JPL Series Diaphragm Chuck performs its clamping movement by material deformation which features high repeatability and low maintenance requirements. Compared to regular wedge-hook power chucks, JP/JPL diaphragm chuck owns high repeatability of 0.005mm, and longer product life since JP/JPL has no clearance, no sliding parts to wear out. JP is designed for high speed turning machines. It incorporates balancing-weights to eliminate centrifugal force. JPL is specially designed for precision grinders. The chuck is with low profile and mass which enable your machines to have high performance and high chucking accuracy.
