Rotating clamping pneumatic cylinders CPV

Description

Rotating clamping pneumatic cylinders are meant for installation in metal-cutting machine tools as a powered chuck drive. For preventing pressure drop in cylinder hollows, when there is an unexpected pressure drop in feeding system, pneumatic valves are built-in in pneumatic cylinder, which automatically disconnect cylinder hollows from feeding system and secures keeping of workpiece clamping force in the chuck till machine spindle stops.
Pneumatic cylinders with piston position control are meant for installation in automated machines, that contains pneumatic control valve with electrical control.
For pneumatic cylinders with stroke control – the customer installs induction switch.
Three-piston pneumatic cylinders CPV-250.3 are meant for height clamping efforts, mainly for lathe chucks ø315 - ø400 mm.
