Vertical 4-roller spinning machines for producing aluminium wheels

The vertical spinning machines type VFM 600 and VFM 800 are particularly designed for producing aluminium wheels starting from forged or cast preforms. Said machines possess 4 forming rollers which may be programmed independently from each other. The resulting design with a total of 8 CNC axes permits extremely short setting times. In connection with the amply dimensioned and easily accessible working range, set-up times are reduced to a minimum. Manual adjustments are not required. Loading the machines, for example, may be achieved through a robot with double gripper. After forming, the first gripper unloads the completed workpiece and the new preform is placed onto the tool in the same operation. Preforms and completed rims may be picked up or deposited outside the machine at any defined point of supply

Features

  • Vertical design, modern and solid machine design in closed  framework construction with overall enclosure
  • Feed of spinning roller through hydraulic servo CNC axes
  • Hydraulic ejector in main and tailstock spindle
  • Tailstock spindle optionally driven
  • Machine optionally equipped with electric tool heating and/or cooling unit easy to achieve automation by using a loading / unloading robot
  • Fast roller and tool change through optimal access to the machine

Advantages

  • High forming force in vertical and radial direction resulting in high degrees of forming even with large material sizes
  • High rigidity of the machine owing to closed framework construction resulting in a reproducible and dimensionally solid product
  • Standard CNC control and customary linear guideways resulting in safety of operation and a problem free maintenance
