Cincinnati Milacron spindle and motor spindle repair
Brochexpress is an independent workshop specializing in the repair, maintenance and diagnostics of Cincinnati Milacron spindles and motor spindles — a historic American manufacturer of vertical and horizontal machining centres, widely represented across the French and European machine base.
Cincinnati Milacron, an American pioneer of machining centres
TLDR: Cincinnati Milacron (Ohio, USA) is a historic machine-tool manufacturer whose vertical and horizontal machining centres (Arrow, Sabre, T series) have equipped a large number of general engineering and subcontracting workshops in France and Europe for several decades.
Founded in Ohio, Cincinnati Milacron established itself over the decades as one of the great names of North American machine tools, with a range covering compact vertical machining centres, horizontal centres with pallet changers and production milling machines. Many machines from this manufacturer, installed in France as early as the 1980s-1990s, are still in production today in general engineering workshops, automotive subcontracting and technical training — which makes for a machine base that is still very much present, with recurring spindle maintenance and overhaul needs.
A range of robust spindles, built for production
TLDR: Cincinnati Milacron spindles stand out for their robustness and mechanical simplicity (belt or gearbox drive), with standardised ISO 40, CAT 40 and BT 30 interfaces depending on the series, well suited to general engineering and series production.
The Arrow series vertical machining centres, the compact Sabre centres and the T series horizontal centres rely on mechanically robust spindles, designed for intensive industrial production use. These spindles, driven by a timing belt or gearbox depending on the machine generation, offer good thermal dissipation and easier maintenance thanks to a proven design. On older machines fitted with Acramatic controls, as on models retrofitted with Siemens or Heidenhain, the spindle mechanics remain largely compatible with our repair and overhaul work.
Cincinnati Milacron spindles covered (non-exhaustive list)
- Vertical machining centre spindles, Arrow and Sabre series
- Horizontal machining centre spindles, T series, with pallet changer

Frequently asked questions
Do you repair spindles on older Cincinnati Milacron machines with Acramatic controls?
Yes, we work on the spindles of these machines whatever the generation of CNC control, including on fleets retrofitted with Siemens or Heidenhain.
Which spindle interfaces do you handle on Cincinnati Milacron centres?
Mainly ISO 40, CAT 40 and BT 30, depending on the series and year of manufacture of the machine.
Do you work on the T series horizontal centres with pallet changer?
Yes, we diagnose and repair the spindles of these centres, taking into account the specific constraints linked to the pallet changer.
What is the average lead time for a full overhaul?
Allow around 20 working days in the workshop, depending on the condition of the spindle and the availability of parts (bearings, seals, belts, specific components).
Do you offer a preventive maintenance contract for a fleet of Cincinnati Milacron machines?
Yes, we set up preventive maintenance programmes tailored to your production rate, particularly relevant on machines still in operation after several decades.
