BRUCKNER LIVE CENTERS
NC AND NCE TYPE WITH INTERCHANGABLE INSERTS

Types NC, NCE 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 NC 33, NC 43
  • For High RPM with thread for draw-off nut 
  • Centerpoint 60°/40° 
     

Technical Features:
  • Concentricity Runout
    - max. 0.005 mm (.0002")
  • Two Series
    - Type NC 33 with slim housing for unhindered operation.  Minimum rolling resistance through low-friction bearings.  For small and medium workpieces.
    - Type NC 43 with extra high-duty bearings for greater loads. 
  • Centerpoint 60° on request
  • TOP-SEAL-SYSTEM
Applications:
  • For turning operations requiring high r.p.m.  Triple-layer protection of bearings from penetration of coolant by the TOP-SEAL-SYSTEM.

Types NCE 34, NCE 44
  • For High RPM with thread for draw-off nut
  • Rotating body with internal taper 1:7.5 for interchangeable inserts

Technical Features:
  • Concentricity Runout
    - max. 0.005 mm (.0002")
  • Two Series
    - Type NCE 34 with slim housing for unhindered operation.  Minimum rolling resistance through low-friction bearings.  For small and medium workpieces.
  • Type NCE 44 with extra high duty bearings for greater loads.
  • TOP-SEAL-SYSTEM
Applications:
  • Variable clamping possibilities for NC-turning through interchangeable inserts.  In the case of a collision or insert wear, type NCE offers the advantage that, simply by changing the insert, the high-performance center is immediately ready for use again.
