Preventive maintenance on the spindle is to detect in advance possible anomalies at the costumer’s place. This procedure on a regular basis will help extend the spindle life and to minimize breakdown on CNC machine.

  • Testing of the run-out of the taper in µm
  • Testing the surface contact of the taper (%)
  • Verification of the temperature at the maximum speed
  • Testing of run-out with calibrated test bar at 30 mm and 300 mm
  • Analysis of the bearings condition
  • Analysis of the vibration level in mm/sec
  • Verification of the spindle lubrication system and chilling unit
  • Testing of the retention force (Kn) of the draw-bar system
  • Proceed to the electrical test of the stator (if needed)
  • Verification of all proximity sensors
