outer diameter grinding 2000 mm & high speed spindles

We manufacture high speed spindles, especially for grinding- and precision-machines:

  • these spindles are turning at high revolutions and have to run absolutely smoothly
  • very close bearing tolerances and a perfect centricity require tolerances on the order of mikrons
  • tolerances of h5, h4 und h3 are not unusual for these demanding parts




These spindles combine extreme requirements::
  • starting with high-grade tool-steel
  • gun-drilled for cooling water and bearing oil
  • bearing seats induction hardened
  • ground to closest tolerances
  • some surfaces with super-finish
  • including individual quality reports
  • even large spindles up to 300 kg and 500 mm diameter can be ground
  • ready for final assembly
In order to protect the know-how of our customers we regret not being able to show pictures.
