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
