Diaphragm Power Chuck Introduction

JATO JP/JPL Series 3 Jaw Diaphragm Power Chuck performs its clamping movement by material deformation which features high repeatability and low maintenance requirements. Compared to regular wedge type 3 jaw power chuck, JP/JPL diaphragm chuck owns high repeatability of 0.005mm, and longer product life because JP/JPL has no clearance, no sliding parts to wear out.

JP/JPL Series 3 Jaw Diaphragm Power Chuck now has two models:

ĦE JP Diaphragm Power Chuck for CNC Lathe
ĦE JPL Diaphragm Power Chuck for Grinders


JP is designed for high speed and high accuracy turning machines. JP incorporates weights to eliminate the centrifugal force. Dynamic balancing can be easily adjusted by integrated balancing weights. Clamping force remains high and stable when speed is up to 8000RPM. JP diaphragm chuck is widely used in high speed lathes or NC turning centers which require micro-meter chucking accuracy.

JPL is specially designed for ID/OD grinders or NC grinding centers. This chuck is with low profile and has low weight design which can enable your machines to have high performance and micro-meter chucking accuracy.

JP Series Diaphragm Power Chuck
  • Repeatability is within 0.005mm.
  • High speed up to 8000 RPM.
  • Compatible with Kitagawa B200 Power Chuck in installation.
  • Anti centrifugal force design by incorporated weights. Clamping force remains high when high speed machining.
  • Dynamic balancing weights are integrated for fine balance adjustment.
  • No sliding part to wear out.
  • No lubrication is needed.
  • Clamping force and stroke is proportional to the cylinder pull force.
  • Ideal for 2nd operation. Ideal for fragile parts, thin-wall parts chucking.
