PIPE MACHINING: PNEUMATIC FRONT-END CHUCKS The pneumatic front-end chucks are optimally suited for machining the ends of pipes, especially large and long pipes like the ones used for extracting crude oil or natural gas. For this, a chuck is mounted to the front and rear sides of the machine spindle. This combination allows large chipcutting performance at high turning precision. Setup and mode of operation A special feature of this chuck is a pneumatic piston built into the chuck body and supplies the chucking power. The workpiece is clamped or released by compressed air supplied, with chuck...

The hydraulic front-end chucks are optimally suited for machining the ends of pipes, especially large and long pipes like the ones used for extracting crude oil or natural gas. For this, one chuck is mounted to the front and one to the rear side of the machine spindle. This combination allows large chipcutting performance at high turning precision. Actuation HVE-IZ During pipe machining, the clamping system is decoupled from the supply via relief valves. A pressure accumulator ensures a sufficient resupply. A sensor system detects any drop in pressure. The HVE-IZ chuck is actuated via injection...
