BRUCKNER DEAD CENTERS
FORMS E, L, AND V

Common Technical Features:
  • Roundness of Carbide:  Out-of-roundness - 0<0.001 (.00003")
  • Taper Shank of Tolerance:  The deviation of taper 'Z' is < AT4 (guage accuracy)
  • Out of Roundness:  Very narrow eccentricity 'V' of the 60 point to the taper shank
  • Hardened Taper Shank:  The taper shank is case-hardened for protection from damage
  • Carbide:  We use only top quality carbide to achieve maximum safety
  • Regrinding Line:  On the useful end of the carbide a usable limit is marked by a brazen line

Form V

 
  • Solid Carbide point, 60 with safety core
  • Length to DIN and extended
  • Patented Safety Core - In BRUCKNER Form V Dead Centers with a carbide diameter of 20 to 45 mm, a patented safety core is integrated.  If there is a fissure in the joint between carbide and base metal, e.g. caused by operating or handling errors, the safety core prevents the carbide point with the mounted workpiece from slipping.  Thus consequential damage is avoided.
