Vertical three-roller flow-forming machine

This machine for production of internally toothed clutch/coupling and gearbox components from rounds, preforms or forged blanks using the flow-forming process meets maximum flexibility and productivity requirements. The machine’s vertical design assures decisive advantages over the customary horizontal flow-forming machine type.

Features

  • Vertical type, stable machine design with all-enclosing housing
  • Compact space requirements thanks to vertical design
  • Main spindle driven by a frequency-controlled three-phase motor
  • Three-roller flow-forming support with four-axis CNC control
  • Vertical feed of the three-roller flow-forming support by means of two hydraulic CNC-controlled feed cylinders with optimum force-application points
  • Internal and external hydraulic ejectors on the main spindle
  • High-speed tool and roller changing thanks to optimum machine accessibility
  • Good automation potentials via attachment of a loading/unloading system

Benefits

  • Thanks to its vertical orientation, the three-roller flow-forming support possesses excellent self-centring characteristics
  • Flow-forming support, tool mandrel and tailstock sleeve remain unaffected by gravity throughout the forming process
  • Short cycle times
  • Optimum production results thanks to vertical machine design
  • High flexibility thanks to the use of a modern CNC control system
