BRUCKNER LIVE CENTERS
SE AND SEG TYPE
 

Types SE, SEG with Interchangeable Inserts

Common Technical Features:
  • Housing - Drop-forged (tensile strength of the high-quality material used:  approx. 1,000 N/mm2
  • Taper Shank without Bore - Therefore it is not weakened.  Thus high moments of deflection can be obtained without any permanent bend to the large taper diameter.
  • High Concentricity accuracy - Guaranteed by the test report.
  • Large-dimensioned precision roller bearings, free from clearance - for taking up the radial and axial forces.  No bearings in the taper shank.
  • Seal Ring - Protects the bearings from dirt and coolant.
     
Types SE and SEG
  • Rotation body with 1:7.5 internal taper for interchangeable inserts
Technical Features:
  • Concentricity Runout
    - Type SE  max. 0.008 mm (.0003")
    - Type SEG  max. 0.003 mm (.0001")
  • With thread for draw-off nut
  • For operations with heavy flows of coolant we recommend the use of our supplementary seal
  • Regrinding sleeve available for regrinding interchangeable inserts
Applications:
  • For individual, small and serial production.
  • Advantages:
    - If the centerpoint shows signs of wear, only the insert has to be changed.  Thus no repair costs or standstill time will accrue.  The insert is removed with two spanners applied to the spanner flats
    - Multiple use is made possible by eight different insert styles
