KSB AG: reducing machining time in valve production by 50%

Task Setting

  • Achieve a drastic reduction in machining time whilst increasing process dependability in valve manufacturing
  • Universal machining centre providing the appropriate stability for the machining of grey cast iron and ferrocast

Project scope and solution

  • HELLER MCH 280 with programmable U axis and exchangeable out-facing heads
  • Integrated out-facing slide with direct drive incorporated in the machine
  • Enhanced 60kW gear unit required for roller burnishing operations


  • Sealing flange can be machined on MCH 280 using a single cutting edge resulting in significant time savings; in case of tool breakage only one indexable insert is affected instead of 12 cutting edges
  • Thanks to freely programmable feed and out-facing slide, machining of turned groove is possible on MCH 280 without any problem
  • Out-facing slide enables precise definition of cutting point on the cutting edge
  • No collision path due to coupling of out-facing slide through the centre of the spindle
  • Tool weights of up to 35kg with 50Nm tilting moment
  • 50% reduction in machining time and time savings in terms of setting operations, since all machining operations formerly accomplished on two machines can now be performed on a single machine
