01 — Repair process

From diagnosis to start-up

  1. Dismantled spindle housing with the bearing seat and the spindle shaft on a workbench

    Diagnosis

    Correct fault diagnosis is the basis of every overhaul: FFT vibration analyser, OTT-JAKOB clamping force meter, surge winding tester, insulation resistance measurement.

  2. Bearing rings and spindle sleeves laid out on the table after disassembly

    Disassembly

    We strip the spindle down to its subassemblies and inspect every component — bearings, shaft, taper, clamping system, encoder.

  3. Spindle shaft with the disc spring stack of the clamping system

    Reconditioning

    We recondition SK and HSK tapers and clamping systems, replace encoder discs and make replacement parts for damaged components using our own machine park.

  4. Measuring the tool clamping force — a gauge with a digital readout mounted in the spindle

    Balancing and testing

    At our diagnostic stations we balance and test the spindle across its full speed range. The customer receives a full measurement report.

  5. Spindle after overhaul on a workshop stand — view of the nose and flange

    Installation and start-up

    On request, we remove the spindle from the machine and, after the repair, install it and start it up at the customer’s site.

04 — Diagnostics

Correct fault diagnosis is the basis of every overhaul

A very important aspect of any spindle overhaul is a correct diagnosis of the damage. Our company has the equipment needed to carry out such a diagnosis.

Diagnostic equipment

  1. OTT-JAKOB tool clamping force meter
  2. FFT spindle vibration analyser
  3. Dynamic balancing machine
  4. Heidenhain measuring transducer amplitude meter
  5. Bearing preload gauge
  6. Surge winding tester (identifies e.g. inter-turn short circuits)
  7. Winding and insulation resistance meter
  8. Set of reference gauges for HSK tapers

05 — Scope of repairs

We repair spindles

We overhaul synchronous and asynchronous motor spindles.

  1. Weight small and large – from 1 kg to 1 t
  2. Drive with mechanical and electric drives
  3. Motor with asynchronous and synchronous motors
  4. Cooling air-, water- and oil-⁠cooled
  5. Bearings with ball and roller bearings
  6. Bearing material with steel and hybrid / ceramic bearings
  7. Tool change with manual and automatic tool change
  8. Lubrication grease- and oil-⁠lubricated
  9. Application for metal, composite, wood and glass processing machines

Balancing and testing

We have suitable diagnostic stations that allow us to balance and test the spindle across its full speed range. The customer receives a full report of the measurements taken.

Parts in stock

Most of the spindles we overhaul come from CNC machines. For this type of spindle we keep bearings and spare parts in stock. This allows us to carry out a standard overhaul within a few working days.
