The truck industry is foreseen as a potential buyer for the DV-Transfer 550, Double Spindle Turning Machine, a twin pick-up spindle VTL, which can balance the workpieces as well.

Twin pick-up spindle VTL balances too The truck industry is foreseen as a potential buyer for the DV-Transfer 550, Double Spindle turning machine - a twin pick-up spindle VTL - said Hessapp at the recent EMO. This heavy duty machine features a common cross-rail on which are mounted two 65kW/1028Nm/2800 revs/min, A6 nose pick-up spindles to machine - and balance - heavy truck components. These include brake rotors, hubs, flywheels, ring gears and brake drums.

Hessapp said that the high rigidity of the machine allows the turning, milling, drilling and balancing in an optimum way.

The in-machine balancing equipment was developed in close co-operation with Hofmann Auswuchttechnik in Pfungstadt, Germany.

Balancing is based on integrating a computer system with a traditional balancing spindle, only this time using the machine spindle of the DV-Transfer 550.

Maximum turning diameter is 500mmand maximum swing, 550mm or 600mm diameter.

Maximum workpiece length, including chuck, is 450mm.

The spindle is rated at 65kW (40% duty cycle)/1028Nm/2800 revs/min.

Traverse rates are 45m/min in X, or with linear motor actuation, 60m/min and 30m/min in Z.

The 12-tool turret accepts tool shanks of 50mm diameter (DIN 69880) and live tooling is optional.
