CNC Spindle
Regeneration and Repair
Electrospindles · milling spindles · turning · grinding · Perske · GMN · Weiss · HSD
The spindle is the heart of a CNC machine tool. Worn bearings, axial runout, a damaged encoder or rotor cause precision loss and downtime. We regenerate spindles with full bearing replacement and radial runout testing.
CNC spindle regeneration — full range of services
Precision bearings
Replacement of ceramic and steel ABEC-7/P4 class bearings. Installation with controlled preload force.
Rotor balancing
Dynamic balancing of spindle rotor on a balancing stand. Vibration reduction below ISO standard.
Stator windings
Diagnostics and repair of electrospindle windings. Insulation replacement, voltage testing.
Spindle encoders
Replacement or regeneration of spindle encoders. Spindle orientation calibration (M19).
Radial runout testing
Radial and axial runout measurement after repair — measurement protocols.
Seals and cooling
Seal replacement, cooling channel regeneration, rotary union replacement.
Spindle regeneration at EFIXLAB: precision mechanics for CNC
- ABEC-7 class bearings — we use FAG, NSK, SKF bearings of P4/P2 class with certificate.
- Test bench — every spindle is tested on a bench: RPM, temperature, runout.
- Electrospindles and mechanical — we regenerate high-speed spindles (HSD, Perske) and conventional ones.
- Fast turnaround — diagnostics up to 5 business days, regeneration 5–7 business days. As a rule — time may be extended depending on component availability and repair complexity; deadlines agreed individually.
- 12-month warranty — on all work performed.
- Measurement protocol — every spindle is returned with a runout and test protocol.

Frequently asked questions
Regeneration cost is typically 30–60% of the price of a new spindle. We send the exact quote within 24h.
Diagnostics: up to 5 business days. Regeneration: 5–7 business days after approval. As a rule — repair time may be significantly extended depending on component availability and repair complexity. Deadlines are agreed individually with the client.
We use FAG, NSK, SKF bearings of ABEC-7 (P4) class or higher.
Ship by courier — the spindle must be secured at the taper/chuck.
