About the Royal spindle
Royal is a respected spindle manufacturer combining modern technology with precise craftsmanship. The company has earned customer trust through reliable solutions and ongoing development, providing spindles tailored to various industrial applications.
Diagnosis and Refurbishment of Royal Spindles
Each Royal spindle repair begins with thorough diagnostics, including vibration analysis, geometry measurements, bearing condition assessment, and inspection of lubrication and cooling systems. Based on these, we develop a precise service plan that may include bearing, seal, and bush replacement, rotor refurbishment, taper geometry restoration, and dynamic balancing. Royal spindle repairs are carried out with the highest precision, in compliance with quality standards and using components from reputable manufacturers.
Spindle Reception
- Device registration.
- Initial visual inspection (mechanical damage, overheating marks, oil/grease leaks).
Preliminary Diagnosis (without disassembly)
- Shaft runout measurement.
- Check of radial and axial play.
- Acoustic testing.
- Rotation test (if possible) – only for motor spindles with working drive.
Spindle Disassembly
- Disassembly into individual components.
- Damage documentation.
- Assessment of bearings, seals, rotor, shaft, taper, housing.
Cleaning and Technical Evaluation
- Ultrasonic or chemical washing.
- Component wear assessment.
- Identification of parts for replacement or refurbishment.
Quotation and Approval
- Service report and quotation.
- Waiting for customer approval.
Repair and Assembly
- Replacement of bearings, seals, socket refurbishment.
- Winding, sensor, encoder repairs (in motor spindles).
- Precise adjustment of clearances and alignment.
- Assembly in clean conditions with proper balancing.
Final Testing
- Vibration and noise measurement.
- Thermal and load tests.
- Electrical tests for motor spindles.
Final Report and Shipping
- Final documentation.
- Proper protection of the spindle for transport.
OEM Standard Royal Spindle Service
When repairing Royal spindles, we use technologies and procedures aligned with OEM standards, ensuring long device lifespan and reliability post-service. Our extensive spare parts warehouse allows us to significantly reduce turnaround times, minimising production downtime for our clients. We also offer component upgrades and periodic inspections as needed. Each repaired spindle undergoes rigorous final tests at specialist measurement stations, including cold and hot operation tests, runout and noise measurements, and performance evaluation. All works are covered by warranty.
Differences Between Classic Spindle and Motor Spindle Royal
| Aspect | Classic Spindle | Motor Spindle |
|---|---|---|
| Drive | External (e.g., belt drive) | Built-in motor |
| Diagnostics | Primarily mechanical | Mechanical + electrical |
| Sensors/Electronics | None or minimal | Encoders, sensors, control system |
| Service Complexity | Low to medium | High – requires special tools and expertise |
| Balancing | Rotor and shaft | Entire motor-rotor unit |
| Spare Parts | Standard | Dedicated, hard to source |
| Repair Cost & Time | Usually lower | Usually higher – due to precision and electronics |
Summary
Service of classic Royal spindles focuses on mechanical aspects – bearing replacement, clearance setting, cleaning. Motor spindle service also requires knowledge of electromechanics and electronics. Therefore, repair should be carried out in laboratory conditions with the highest precision and cleanliness.
