Disassembly and Inspection

The spindle is disassembled, and components like bearings, seals, and housing are inspected for damage or wear. Common issues include worn bearings, bent shafts, or misalignment.

Cleaning and Assessment

All parts are thoroughly cleaned to remove debris, lubricant residue, and contaminants. This allows for an accurate assessment of which components need replacement.

Component Replacement or Repair

Damaged or worn components, such as bearings, seals, and lubricants, are replaced. Bearings are often the most common part that requires replacement, as they directly impact spindle performance and accuracy.

Shafts may be re-ground or straightened if there’s deformation.

Reassembly Alignment and Balancing

The spindle is reassembled with new or repaired components, and precision adjustments are made to ensure alignment.

The spindle is dynamically balanced to prevent vibration during operation, which is crucial for maintaining accuracy.

Testing and Quality Control

After reassembly, the spindle is tested under load and at varying speeds to confirm it meets performance standards. Vibration analysis and temperature monitoring may also be done to ensure stability and longevity.
