Air operated self-centering chuck with through-hole PPT

Description

Air operated self-centering chuck with through-hole model PPT-450.140 (analogue of Bison chuck 2500-400-140) serves for kitting of special lathes with clamped spindle stop, meant for pipe machining in oil and gas producing industry. Pneumatic actuator allows to install two chucks on a machine (on a spindle nose and back spindle terminus of a lathe) for better centering of pipe workpiece.

The chuck is equipped with a collector, which is mounted on the front headstock of the machine.

Increased movement of clamping jaw allows to clamp a pipe without couplings removing. For emergency shutting-down of spindle rotation when loss of pressure in a chuck hollow, there is a pressure fall control mechanism installed.
