We repair synchronous and asynchronous electric spindles.
We have appropriate diagnostic stations that allow us to balance and test the spindle across its entire rotational range. The customer receives a full report of the measurements taken.

We repair spindles:
- small and large – from 1 kg to 1 t
- with mechanical and electric drives
- with asynchronous and synchronous motors
- air, water, and oil cooled
- with ball and roller bearings
- with steel and hybrid/ceramic bearings
- with manual and automatic tool change
- lubricated with solid grease and oil
- for metal, composite, wood, and glass processing machines
- from various machine manufacturers: SW, DECKEL MAHO, DMGMORI, GILDEMEISTER, GROB, MITSUBISHI, MAKINO, MATSURA, KITAMURA, STAMA, FANUC, HERMLE, VOUMARD, JUNG, MIKRON, VOLLMER, HURON, FREST, CHIRON, OKUMA, QUASER, HURCO, ELUMATEC, WEEKE, HOMAG, IMA, FADAL, UVA, BRIDGEPROT, STARRAG, BROTHER, HARDINGE, HYUNDAI, AXA, PORTATEC, SERON, KILMA, BYSTRONIC, HITACHI, SEIKI, MAG, MAZAK, HAAS, EMAG, FFG, MECCANADORA, NOVA, ALZMETTAL, DOOSAN, IMA-TECNO, WEISSER, ABB, SCHAUDT MIKROSA, STUDER, TRAUB and many other

Specialized
measuring instruments
A very important aspect of spindle repair is the correct diagnosis of spindle damage. Our company has the necessary equipment to carry out such a diagnosis
- OTT-JAKOB tool clamping force meter,
- FFT spindle vibration analyzer,
- dynamic balancing machine,
- Heidenhain measuring transducer amplitude meter,
- bearing preload gauge,
- surge winding tester (allows identification of inter-turn short circuits, for example),
- winding resistance and insulation resistance meter,
- set of reference gauges for HSK tapers.
