Diagnostics and refurbishment at the highest level
Weig Fischer spindle repair at Fumak starts with a thorough analysis of the device's technical condition – both mechanical and electrical. We use modern diagnostic methods, including vibration tests, bearing measurements, and component inspections using technical microscopes. After identifying the problem source, we perform full refurbishment: bearing replacement, dynamic balancing, cooling system inspection, seal repairs, and cleaning and lubrication of moving parts.
Acceptance of the Electrospindle for Service
- Device registration in the system.
- Initial visual inspection (mechanical damage, coolant leaks, signs of overheating).
Preliminary Diagnostics (Without Disassembly)
- Laser-based runout measurement.
- Bearing condition and play check.
- Acoustic and vibration testing.
- Electronic subsystem inspection – sensors, encoders, drives.
Electrospindle Disassembly
- Module-based teardown – motor, bearings, encoder, housing cover.
- Recording of damaged components.
- Inspection of rotor, stator, and electronic components.
Cleaning and Technical Assessment
- Ultrasonic cleaning of electronic modules.
- Degreasing and descaling of mechanical parts.
- Wear assessment of bearings, seals, windings.
Quotation and Customer Approval
- Preparation of a detailed repair cost estimate.
- Waiting for the client’s approval to proceed.
Repair and Assembly
- Replacement of bearings, seals, and regeneration of bearing seats.
- Repair of motor windings and encoder circuits.
- Calibration and adjustment of electronic controls.
- Clean-room assembly following anti-contamination procedures.
Final Testing
- Vibration and noise measurement at various RPMs.
- Thermal testing in a climate chamber.
- Verification of encoder and temperature sensor accuracy.
Final Report and Shipment
- Photographic and test documentation.
- Anti-vibration packaging for safe transport.
Precise calibration and tests after repair
Each Weig Fischer spindle undergoes a series of tests confirming its functionality and compliance with manufacturer parameters after repair. Calibration, rotation tests, temperature, vibration, and axial and radial runout checks are performed in our advanced test laboratory. Use of high-precision balancing machines reduces vibrations to a minimum, significantly extending spindle life.
We have our own technical facilities, spare parts, and experience servicing spindles of renowned brands like Weig Fischer. Choosing us means safety, reliability, and real support for your machine park, directly translating to production continuity and reduced costly downtime.
Differences between Classic Spindle and Electrospindle Weig
| Aspect | Classic Spindle | Electrospindle |
|---|---|---|
| Drive | External (e.g., belt-driven) | Built-in motor |
| Diagnostics | Primarily mechanical | Mechanical + electronic |
| Sensors/Electronics | None or minimal | Encoders, sensors, control unit |
| Service Complexity | Low to medium | High – requires specialised tools and knowledge |
| Balancing | Rotor and shaft | Entire motor-rotor assembly |
| Spare Parts | Standard | Dedicated, harder to source |
| Repair Cost & Time | Typically lower | Generally higher – precision and electronics |
Summary
Repairing electrospindles Weig requires both mechanical and electronic expertise. With advanced equipment and experienced engineers, we offer comprehensive regeneration services that minimise downtime and extend equipment lifespan.
