A bit about the electrospindle DMG
DMG Mori is a leader in CNC machine manufacturing, offering advanced electrospindles with high precision. Their solutions feature superior performance, low vibration, and long service life, making them valued by operators in the most demanding applications.
DMG Electrospindle Repair Process
Disassembly and diagnostics of DMG electrospindles start with a detailed examination of all components to identify the source of the problem. Specialists use advanced measurement technologies to precisely determine the technical condition of the spindle. After thorough analysis, a diagnostic report is prepared.
Electrospindle refurbishment includes several key stages, from cleaning and replacing worn parts to precise balancing and testing. Standard DMG electrospindle repairs also include control and calibration of all essential spindle operating parameters. Each stage is documented, and the client receives a detailed report of the work performed.
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.

- 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.
Common DMG Electrospindle Faults
DMG electrospindles most commonly suffer from bearing damage and cooling system issues, which can lead to overheating. Other typical faults include wear of mechanical parts and problems with control electronics. Symptoms such as noise, vibrations, or performance drops may indicate the need for repair. Modern technologies like precision dynamic balancing and advanced diagnostic methods are used to fix faults. Specialized equipment enables quick and effective restoration of full spindle functionality.
Differences between Classic Spindle and Electrospindle DMG
| 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 |
