Included Equipment:
Hydraulically working blank centering unit: fastened to the machine bed opening and provided with 120 mm lifting stroke. Radial and axial adjustment via linear recirculating roller guidance systems. Easily adjustable to the respective blank diameter and the tool length via quick-clamping levers. Diameter setting via threaded spindle with position indicator.

Hydraulically actuated blank counter-holder: fastened to the headstock cover and easy to reset via quick clamping levers, to avoid wrinkles and to shorten the production times when forming blanks or preformed workpieces. A hardened and ground steel disk is used for counter-holding the blank. Infinitely adjustable working stroke. Blank counter-holder equipped with linear recirculating roller guidance system.

Six-station tool turret: arranged on the top slide. With this tool turret 6 different tools, such as spinning rollers, profiling rollers, smoothing rollers or turning tools can be used for machining. The top slide has a tool mounting via dovetail guidance with clamping cylinder. A central cylinder lifts the tool after its use out of the fixture of the top slide into the magazine location. The control automatically evaluates the shortest swiveling movement to the respective magazine location. The new tool is lowered and clamped in the fixture of the top slide.

Oil circulating lubrication with cooling for main spindle bearing arrangement.

Ejector against tailstock: control for pushing-off the workpiece from the tool with simultaneous counter-holding by the tailstock. Foot switch for releasing the workpieces.

Protective door, pneumatically actuated: to protect the working area of the machine.

U.S. Electrics: the machine is electrically installed in accordance with the U.S. standards.

Offline programming system: Leifeld Sheet Metal Spinning, based on Opus System.

Special heat protection with water cooling up to a forming temperature of 1000˚ C: cooling water tank, heat protection shield and water cooling for Headstock, slide with turret, roller shaft, tailstock, switch cabinet.

Burner Unit: provides top up heat to the blanks and comprising burner, water cooled, together with adjustable holder, valves, controls and safety equipment.

Electric infrared temperature measuring unit.
