Spindle Motor Repair
Noise, vibration, overheating, seizing and surface quality problems in high-speed spindle motors are assessed on the basis of measurement. The definitive root cause is determined at diagnosis; a symptom is not treated as a diagnosis.

Service overview
Noise, vibration, overheating, seizing and surface quality problems in high-speed spindle motors are assessed on the basis of measurement. The definitive root cause is determined at diagnosis; a symptom is not treated as a diagnosis.
Whether the scope covers the motor or an integrated spindle unit is clarified in your request; it is not assumed that every device has a drawbar.
Which symptoms call for an assessment?
- Noise and vibrationNoise or shaking that increases with speed.
- OverheatingRising temperature in the housing or bearing area.
- SeizingThe shaft does not turn freely or is stiff.
- Surface qualityMarks, waviness or dimensional deviation on the machined part.
A symptom is not a diagnosis; the cause becomes clear during laboratory diagnosis.
Work performed
| Area | Description |
|---|---|
| Bearings and bearing seats | Assessment of wear and play; replacement with appropriate precision. |
| Balancing | Balancing of the rotating assembly. |
| Winding | Electrical measurement and insulation check. |
| Cooling and tool clamping | Cooling channels; the tool clamping mechanism, if the device has one. |
Analysis and testing approach
A gradual run-up is carried out at the speed and under the operating conditions permitted by the model; vibration and temperature are checked. This page contains no invented micron or speed values; results are reported specifically for each device.
Quotation, approval and delivery process
Registration
We record the device details and symptoms and send you a reference number.
Analysis
The fault is diagnosed in the laboratory, so it is clear what has failed.
Quotation and approval
Scope and price are confirmed in writing; nothing is done without your approval.
Repair
The repair is carried out within the approved scope; you are informed of any deviation.
Testing and delivery
The device is tested under suitable conditions and returned with a short technical summary.
Preparing for shipment
State the cooling type (air / water) and, if known, the rated speed. Numerical technical fields are not mandatory; a photo is sufficient.
Frequently asked
It depends on the design of the device; ask in your request and include a photo, and we will advise you.
Balancing of the rotating assembly is within scope; whether it is needed is determined at diagnosis.
