csm_Forkardt_DIAPHRAM_0ff2f62b8b

The N.A. Woodworth diaphragm chuck design is based on simplicity. A diaphragm chuck works similar to the action of an oil can bottom. No sliding parts; no friction, no wear! It operates by a simple flexing action, assuring consistently controlled concentrically.

The dovetail jaw design includes a unitized diaphragm assembly, self contained air cylinder, face plate adapter, rotary slip coupling, and installation instructions.
