Double-sided machining of pipes

Machine type: travelling column machining centre

Task:

Double-sided machining of pipes accompanied by the introduction of radial drill holes on the circumference

Solution:

  • The pipes are deposited manually or by robot onto a pre-centring and then hydraulically clamped using centring clamps
  • Double-sided end machining using centring clamps and introduction of radial drill holes by means of a tilting spindle head
  • Use of an NC rotary table with 3-jaw power chuck on a separate linear axis for automatically rotating the workpiece into the machining position
  • Followed by clamping and drilling once again
