Electrospindle Repair Kessler
We specialise in comprehensive Kessler electrospindle repair – a renowned manufacturer whose spindles are used in the most advanced CNC machines, machine tools, and milling centres. Thanks to many years of experience and modern service facilities, we can restore full functionality even to the most demanding drive units. Each spindle is treated individually – our team analyses not only failure symptoms but also the device's operational history. This allows precise diagnosis and selection of the optimal scope of work.
A bit about the electrospindle Kessler
Kessler is a Swiss company renowned for precision-balanced electrospindles and advanced temperature control. Their products find applications in aerospace, medical, and automotive industries where the highest quality and reliability are required.
Kessler electrospindle diagnostics – precise fault analysis
In the Kessler electrospindle repair process, detailed diagnostics play a key role. We use advanced measurement devices and specialised test stations to detect not only obvious mechanical damages but also irregularities in motor operation, bearing, or cooling system. We perform measurements of axial and radial runout, vibration analysis, and thermal tests. Every spindle coming to our service undergoes a rigorous verification process, which is the foundation of effective and safe refurbishment.
Refurbishment and tests – guarantee of efficiency
After diagnosing faults, we proceed to replacement or refurbishment of worn components – bearings, seals, sensors, coils, windings, and cables. All replacement parts are selected according to Kessler manufacturer's specifications or we use certified substitutes with identical parameters. Our assembly procedures maintain high cleanliness and precision, ensuring the highest quality and durability of the repaired spindle.
Before handing the device back to the client, we conduct extensive dynamic, load, and rotor balancing tests to confirm full efficiency and stable operation under production conditions. The client receives service documentation and warranty for the performed work. Contact us!
Differences between Classic Spindle and Electrospindle Kessler
| 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 Kessler requires both mechanical and electronic expertise. With advanced equipment and experienced engineers, we offer comprehensive regeneration services that minimise downtime and extend equipment lifespan.
