DISASSEMBLY
- All spindle parts disassembly
- All spindle parts disassembly
- Identify reasons for failure
INSPECTION OF FAULTY SPINDLE
- Inspect all critical parts thoroughly
- Perform motor, sensor and other electrical checks
- Identify reasons for failure
- List out corrective actions
- Prepare spindle analysis report
- Prepare spindle repair quotation
PARTS RECONDITIONING AND GRINDING
- Hard-chrome plating and taper grinding
- Bearing housing bore, Spindle shaft (front and rear) diameter grinding. Hard chrome plating if needed
BEARING ASSEMBLY WITH PROPER PRELOAD
- Bearing preload influences speed limits, rigidity and other applicable work loads
- Thrust load is applied to shaft and its axial displacement is measured for obtaining preload
DYNAMIC BALANCING
- Check shaft or rotating mass imbalance of all parts
- Schenck precision balancer is used to ensure conformity to ISO 1940/1 standard
STATOR REWINDING
- Full electrical integrity checks for the spindle motor winding including resistance, impedance and insulation check
- On damaged or burnt out stator rewinding is done to OEM specification
ASSEMBLY
- Ultrasonic cleaning of all spindle parts
- Every spindle component is thoroughly degreased and deburred for sharp free edges
- All mechanical and electrical parts assembly
- Frequent checks after every part assembly/ sub assembly to ensure correctness
ACCURACY CHECK AND TEST RUN
- Test run until maximum speed and ensure thermal saturation
- Clamping force check and test bar check as per ISO 10791-2-1001standard
- Noise test and vibration test (at test bench using field balancer)
