Our Repair Process
Every spindle we service goes through a structured, documented process:
- Complete disassembly and professional cleaning of all components
- Metrological recording – all components within repair scope are measured and inspected
- Precision reassembly with correct torques and bearing preload per manufacturer specifications
- Original EMAG spare parts – all replacement parts are OEM and updated to current design standard
- Lubrication applied to EMAG specification (grease type and quantity)
- Test run on our test bench with full documentation of results
Test Bench Validation
Every reconditioned spindle undergoes a complete test run. The following parameters are measured and documented:
| Parameter | Why It Matters for Your Production |
|---|---|
| Concentricity & axial run-out | Guarantees surface quality and dimensional accuracy |
| Balancing quality | Reduces vibration and extends tool and machine life |
| Hydrostatic flow rate | Maintains optimal lubrication and cooling in all conditions |
| Power consumption | Monitors efficiency and identifies friction losses |
| Temperature behavior | Prevents thermal issues during production |
| Electrical characteristics | Ensures compatibility with your machine system |
When to Consider Spindle Service
Consider a spindle inspection if you notice:
- Loss of accuracy or repeatability
- Increased vibration or noise
- Surface finish issues
- Thermal instability
- Bearing alarms or load irregularities
Early intervention can help prevent secondary damage and extended downtime.
