What is involved in the machine spindle rebuild?

• Upon receipt of your spindle, we disassemble, inspect and quote the spindle rebuild, as follows:
  1. External examination - rust, dents and contamination are recorded
  2. Begin disassembly - taking notes and photos
  3. Inspect components for wear or other damage
  4. Inspect bearings to determine cause of failure
  5. Source required purchase parts
  6. Quote spindle rebuild

• When your purchase order is received, all required components (bearings, o-rings, belts, etc.) are ordered.
• Grinding and other rework is done at this point and may include hard chrome and grinding of components such as spun bearing spacers, housings and shafts. If parts are beyond repair, we can remanufacture them in-house.
• All spindle components are now cleaned, protected and transferred to our clean room facility.
• The drawbar is reconditioned if required. (Including new springs, fingers, etc.)

• Assembly in the clean room includes all critical measurements and/or adjustments. Proper lubrication is applied to the super precision bearings ensuring maximum bearing life.
• Balancing is performed (if design allows) on the shaft assembly before the final assembly.
• After final assembly, the spindle is ready for run-in.
• Run-in allows the lubrication to be properly distributed within the bearing. During run-in, heat, noise and vibration are monitored.
