Task:

Milling of rolled steel profiles up to 8.8 m in length (lift masts for forklifts and high rack warehouses)

Solution:

  • Standard travelling column machining centre with horizontal SK 60 spindle
  • Four tools in a pick-up magazine, consisting of an SK 60 milling cutter with counter bearing, each fitted with
    4 disc cutters of D = 500 mm
  • Hydraulic workpiece clamping device
 

Special characteristics:

  • Prepared for unmanned operation with automated loading and unloading
  • Identification of the raw workpieces lying on the conveyor belt by means of a camera system
  • Prefabricated parts are inserted into the clamping device and removed by means of a gantry loader
  • Automated clamping device for optimal workpiece clamping
  • High-performance chip extractor running in parallel on the X axis
