Buying a new spindle means a cost in the hundreds of thousands to millions of crowns. Refurbishment restores the machine to full function, usually within 2–3 weeks of receiving the part and for a fraction of the purchase price of a new spindle. If the spindle's construction is not critically damaged mechanically, refurbishment is in the vast majority of cases a significantly more economical choice.

Refurbishment is not a makeshift repair — it includes complete disassembly, replacement of worn components (primarily spindle bearings and seals), cleaning, regeneration of the taper bore if needed, and verification of geometry and balancing. The resulting spindle is comparable to a new unit in terms of accuracy and service life, and leaves the workshop with a warranty.

1. Receipt and initial diagnostics

   We receive the spindle together with information about the machine and a description of the problem. We perform an initial inspection — runout measurement, bearing backlash, visual check.

2. Disassembly and inspection

   The spindle is disassembled and the individual components are inspected (shaft, bearings, seals, taper bore, motor in the case of a motor spindle).

3. Quotation

   We issue a detailed price quote with the scope of work and a list of parts to be replaced.

4. Refurbishment (after your approval)

   Replacement of worn components, cleaning, correction of the taper bore if needed, and reassembly with the prescribed bearing preload.

5. Measurement and verification

   Checking runout, geometry, speed and thermal behaviour during a test run.

6. Run-in

   We run the spindle in up to 4,000 rpm. The rest of the speed range needs to be run in directly on the machine according to the manufacturer's prescribed procedure.

7. Return shipment with report and warranty

   We send the spindle back with a measurement report and a warranty on the refurbishment performed.

• Spindles with manual tool clamping (BT, ISO, MAS-BT) and automatic tool change (HSK, BBT, Capto)
• Spindles with mechanical transmission (belt-driven or geared)
• Motor spindles with an integrated motor — refurbishment of the mechanics (bearings, seals); we assess the motor individually

• The spindle ready to ship (protected against further damage during transport)
• Machine type and serial number
• A description of the problem and the circumstances in which it started
• Drawing documentation of the spindle, if you have it — it speeds up the process but is not a requirement
