CNC Spindle Repair – Professional Refurbishment


Our CNC spindle repair includes the complete replacement of high-speed bearings, seals and inductive sensors responsible for tool-clamp detection, piston position and rotational speed. The refurbishment also involves precision taper grinding, clamp-force measurement and thorough cleaning of all spindle elements, ensuring reliable operation.
Professional spindle repair is preceded by a detailed mechanical-optical audit that reveals all damage and defines the scope of work required. This restores the spindle’s factory parameters while minimising downtime and the cost of buying a new component.
In addition to spindle repair, we also refurbish integrated systems: sensory, pneumatic, hydraulic and cooling. This comprehensive approach ensures long-term, trouble-free operation of the entire system.
Every spindle repair concludes with precise static and dynamic balancing to 4G accuracy. Proof of quality is provided by a balancing protocol supplied with the returned spindle.
Frequently asked questions
How long does a standard CNC spindle repair take?
A standard CNC spindle repair usually takes 7 to 14 working days. An express service is also available – within 48–72 hours.
What are the main symptoms of a damaged spindle?
The most common symptoms are: unusual noises (squeals, knocks), temperature above 60 °C, excessive vibration, decline in machining quality and unexpected machine stops — all of these signals can indicate that spindle repair is required.
How much does CNC spindle repair cost?
Repairing a milling spindle usually costs between PLN 12,000 and 18,000 net. For high-speed spindles, the price can range from PLN 15,000 to 40,000. Simple repairs, such as bearing replacement, are much cheaper.
What warranty will I get on the repaired spindle?
Every repaired spindle comes with a written warranty. Detailed terms are agreed individually at the time of order.
What does a standard spindle repair include?
A comprehensive spindle repair includes disassembly, diagnostics, replacement of bearings and seals, taper refurbishment, 4G dynamic balancing, final tests and a full measurement protocol.
How can I avoid costly spindle repair?
To reduce the risk of costly spindle repair, regularly monitor operating temperature, clamp force, bearing lubrication level and vibrations. Preventive maintenance significantly extends spindle life.
Is spindle repair worth it or is it better to buy a new one?
Spindle repair typically costs only 25–30 % of the price of a new spindle and, with factory parameters maintained and shorter lead times, is a far more cost-effective alternative.
