Fidia spindle and motor spindle repair
Brochexpress is an independent workshop specializing in the repair, maintenance and diagnostics of Fidia spindles and motor spindles — an Italian pioneer of 5-axis high-speed machining, a world leader in the manufacture of complex parts and tooling for aerospace, automotive and mould-making.
Fidia, world leader in 5-axis high-speed machining
TLDR: Fidia (an Italian group founded in 1974) designs 5-axis high-speed milling machines and machining centres, with travels ranging from 600x600 mm on compact machines up to gantry milling machines of 20,000 x 3,500 x 2,500 mm, intended for the automotive, mould and die, as well as aerospace and space industries.
Founded in 1974, the Fidia group has established itself as a world leader in the design and production of 5-axis high-speed milling machines and machining centres, specially developed for the manufacture of complex parts and tooling. The manufacturer covers a very wide range of dimensions, from compact 600x600 mm milling machines up to full-scale gantry or twin-gantry milling machines exceeding 20 metres of longitudinal travel. Its range includes in particular the K series (versatile 5-axis HSM milling machines), the GTF series (modular 5-axis gantry milling machines) and the G996RT centre, fitted with a rotary-tilting table and a sophisticated thermal control system using temperature probes to limit geometric drift during long machining operations.
A range of bi-rotary heads and high-power motor spindles
TLDR: Fidia centres integrate continuous bi-rotary heads and high-power motor spindles (up to 88 Nm and 55 kW depending on the model), with typical rotation speeds of 24,000 rpm on an HSK63A interface.
Fidia milling machines are fitted with continuous bi-rotary heads allowing simultaneous 5-axis machining of complex-shaped parts, with a head geometric error measuring and compensation device (HMS, Head Measuring System) on the most advanced models. The associated motor spindles deliver high performance, with rotation at 24,000 rpm delivering up to 88 Nm of torque for 55 kW of power on the most robust configurations, on an HSK63A interface. On models dedicated to aerospace and energy (turbine blades, plastic injection tooling), these spindles are combined with cooling systems using cutting fluid, minimum-quantity lubrication or air blast through the spindle centre depending on the application.

Frequently asked questions
Do you repair continuous bi-rotary heads equipped with the HMS system?
Yes, we work on these heads, taking into account their geometric error measuring and compensation system.
Do you work on the HSK63A motor spindles of the G996 and GTF centres?
Yes, we diagnose and repair these motor spindles, whether on rotary-tilting table configurations or gantry milling machines.
What is the average lead time for a full overhaul?
Allow around 20 working days in the workshop, depending on the condition of the head and the availability of parts (bearings, seals, specific components).
Do you work directly on site for large heads?
Yes, our team travels to diagnose and, where possible, work directly on site to avoid the complete removal of bulky and heavy heads.
Do you offer a preventive maintenance contract for a fleet of Fidia machines?
Yes, we set up preventive maintenance programmes tailored to your production rate, particularly relevant for aerospace and mould-making 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 Fidia range — milling heads and motor spindles for 5-axis high-speed machines — with the responsiveness and rigour demanded by the most exacting industrial environments: aerospace, automotive and mould-making.
Our teams are at your disposal from our sites in Beaurepaire (France) and Lussery-Villars (Switzerland) for a study of your needs, a diagnosis or a personalised quotation.
