CMS spindle and motor spindle repair
Brochexpress is an independent workshop specializing in the repair, maintenance and diagnostics of CMS motor spindles — an Italian manufacturer of machining centres for composite materials, aluminium and light alloys, a benchmark in aerospace, motorsport and marine industries.
CMS, Italian specialist in composite material machining since 1969
TLDR: CMS S.p.A. (founded in 1969 by Pietro Aceti, SCM group) designs machining centres and cutting systems for composite materials, carbon fibre, aluminium, light alloys and plastic, with a strong presence in aerospace, motorsport (F1) and marine industries.
Founded in 1969 by Pietro Aceti, CMS has built recognised expertise in the machining of advanced materials, through customised solutions based on a fine understanding of customer needs. The manufacturer operates in sectors with very high quality and repeatability requirements: aerospace (helicopter and fixed-wing structures), Formula 1, marine, wind energy and eyewear. Its range of fixed- or moving-gantry machining centres (fxb, ares) allows high-speed machining of large panels or long, narrow parts in composite materials, aluminium or sandwich, with single- or multi-spindle configurations depending on production needs.
A range of in-house-designed motor spindles for high-speed machining of advanced materials
TLDR: All CMS motor spindles are entirely designed and manufactured within the group, with power ratings of up to 32 kW, covering a wide range of torque, power and rotation speeds depending on the material being machined.
All the motor spindles fitted to CMS machining centres are entirely designed and produced within the group, the fruit of several decades of experience in machining non-ferrous materials. This in-house mastery makes it possible to offer each customer the motor spindle with the optimal torque, power and rotation-speed characteristics for their specific application, with power ratings of up to 32 kW on the most productive configurations (fxb range). On centres dedicated to demanding composite materials (aerospace, motorsport), very-high-frequency spindles are used for fine machining and detail work, with an advanced vibration control system, essential to prevent delamination of composite materials during machining.

Frequently asked questions
Do you repair the very-high-frequency motor spindles dedicated to fine machining?
Yes, we work on these spindles while taking into account their specific requirements for accuracy and vibration control.
Do you work on the motor spindles of machining centres dedicated to composite materials (carbon fibre)?
Yes, we diagnose and repair these spindles, ensuring their vibration control system is preserved, which is essential to prevent delamination.
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, specific components).
Do you work on the high-power motor spindles (up to 32 kW) of moving-gantry centres?
Yes, we diagnose and repair these spindles, sized for the high-speed machining of large panels.
Do you offer a preventive maintenance contract for a fleet of CMS machines?
Yes, we set up preventive maintenance programmes tailored to your production rate, particularly relevant for aerospace and motorsport workshops.
A reliable partner for your industrial performance
Whether it is an emergency on-site intervention, a full workshop overhaul or a preventive maintenance programme, Brochexpress brings its expertise to your production. As an independent workshop, we work across the entire CMS range — motor spindles for machining centres handling composite materials and light alloys — with the responsiveness and rigour demanded by the most exacting industrial environments: aerospace, motorsport and marine.
