Spindle and motor spindle repair for SCHUNK tool holders
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of spindles and motor spindles fitted with or compatible with SCHUNK clamping systems — the world technology leader in tool holding, stationary clamping and gripping technologies.
SCHUNK, world leader in tool clamping and gripping
TLDR: SCHUNK is the international technology leader in tool and workpiece clamping, gripping and automation technologies, with a tool holder range covering micro-machining through to very heavy machining, whose shrink-fit chucks and hydraulic expansion chucks equip a large share of the machine tool spindles in production.
SCHUNK has established itself as the international technology leader in tool and workpiece clamping, gripping and automation technologies, with a complete product range covering micro-machining and very fine machining through to large-volume and very heavy machining, for milling, drilling, boring and threading. SCHUNK tool holders, whether ER collet chucks, WELDON or Whistle-Notch chucks or shrink-fit chucks, form the interface between the machine tool spindle and the cutting tool — a decisive element for concentricity, rigidity and the surface quality achieved in machining. CELSIO shrink-fit technology enables high-speed machining up to 50,000 rpm, with concentricity accuracy of 0.003 mm or better.
A range of intelligent tool holders for real-time spindle monitoring
TLDR: The iTENDO² sensory tool holder, developed by SCHUNK, combines TENDO hydraulic expansion chuck technology with digital process monitoring, allowing cyclical interrogation of spindle condition and optimisation of cutting parameters to reduce vibration.
The iTENDO² sensory tool holder combines the characteristics of TENDO hydraulic expansion chuck technology with the possibilities of digital process monitoring, in a single intelligent tool holder — a concept that connects directly with the move towards the intelligent spindle that our sector is following closely. By recording vibration data as close as possible to the workpiece, the iTENDO² allows cyclical interrogation of spindle condition with little effort, optimisation of cutting data to reduce vibration, improved tool life and surface quality, and reduced cycle time. This technology illustrates an underlying trend in the sector: embedded intelligence is now moving both into the spindle itself and into the tool holder that interfaces it with the cutting tool.

Frequently asked questions
Do you repair spindles fitted with CELSIO shrink-fit chucks (up to 50,000 rpm)?
Yes, we work on these spindles, taking account of their specific concentricity requirements.
Do you work on spindles fitted with the iTENDO² sensory tool holder?
Yes, we diagnose and repair these spindles, independently of the associated digital monitoring system.
How long does a full overhaul take?
Allow around 20 working days in the workshop, depending on the condition of the spindle and the availability of parts (bearings, seals, specific components).
Do you work on all spindle interfaces compatible with SCHUNK (HSK, ISO, BT)?
Yes, we diagnose and repair spindles whatever their original interface, independently of the SCHUNK tool holder used.
Do you offer a preventive maintenance contract for a fleet of machines fitted with SCHUNK tool holders?
Yes, we set up preventive maintenance programmes tailored to your production rate.
