Rotary-driven slide boring bar

The modular slide boring bar is rotary-driven by the machine spindle, supported by the counter
bearing.

The boring bar is used in hydraulic block manufacturing and machines the transition from the main bore to the cross bore. The slide stroke is 18 mm with an external diameter of 50 mm. The indexable insert holders can be replaced after each machining task (semi, finish). The modular structure means that the boring bar can be flexibly extended using an adapter. The boring bar has a length of 458 mm without an adapter (HSK100 collar up to cutting edge) and 790 mm with an adapter.

 

Functional sequence

  • Insertion when stationary and counter-bearing positioned
  • Retraction to the middle of the cross bore
  • Spindle set to machining speed
  • Transition removed (forwards and back)
  • Boring bar moved to middle of cross bore
  • Spindle stopped
  • When stationary, removed from bore
  • The counter bearing is pulled out of the bearing hole

 

Cutting data

  • n = 260 U/min
  • vc = 116-130 m/min
  • f = 0.20 mm/U
  • fz = 0.10 mm/U
  • vf = 52 mm/min
