Zayer spindle and motor spindle repair
Brochexpress is an independent workshop specializing in the repair, maintenance and diagnostics of Zayer spindles and milling heads — a Spanish Basque manufacturer of large gantry and portal milling machines, with a strong presence in aerospace, energy and shipbuilding.
Zayer, Basque manufacturer of large-format milling machines since 1950
TLDR: Zayer (Vitoria-Gasteiz, Spanish Basque Country, since 1950) designs bed-type, portal and gantry milling machines for machining large, complex workpieces, with a strong presence in aerospace (invar tooling, landing gear, fuselage components), energy and shipbuilding.
Since the late 1940s, Zayer has designed and manufactured milling machines and machining centres in Vitoria-Gasteiz capable of handling workpieces up to 13 metres high, in production workshops of 20,000 m². The manufacturer covers a broad spectrum of sectors: invar mould tooling, landing gear and fuselage components for aerospace, Pelton, Francis and Kaplan turbines for hydraulic energy, as well as structural parts for the railway industry (switch points, crossings, frames). Its gantry milling machines, such as the Thera, feature advanced interpolation cycles (known as 5+1) allowing the head to be tilted at any angle and the linear axes to be interpolated simultaneously with the rotary axes, while the Arion range, geared towards Industry 4.0, offers remote control and real-time correction of thermal drift.
A range of 5-axis heads and high-power spindles for heavy machining
TLDR: Zayer milling heads cover a wide power range (20 to 54 kW depending on the model) with very fine automatic rotation (down to 0.001°) and ISO 50 or SA 50 interfaces depending on the machine generation.
Zayer milling heads come in fine-rotation automatic versions (in steps of 0.001° on the most recent models), continuous-rotation spherical heads and direct-output heads, covering both conventional 3-axis machining and simultaneous 5-axis machining of complex parts. The 5-axis heads of the Arion range, geared towards aerospace and mould-making, deliver power ratings of 24 to 32 kW, while the heaviest configurations on portal machines can reach 37 to 54 kW with torques above 200 Nm. Historic bed-type machines use an SA 50 spindle taper, while more recent generations favour ISO 50 (DIN 69871).
Zayer heads and spindles covered (non-exhaustive list)
- Fine-rotation automatic 45° heads, ISO 50 taper
- Continuous-rotation spherical heads and direct-output heads
- 5-axis tilting heads, Arion range, 24-32 kW power
- Bed-type milling machine spindles, SA 50 taper
- Spindles for large-dimension portal and gantry milling machines, up to 54 kW
Interfaces and specifications
The Zayer heads and spindles we repair come mainly with ISO 50 (DIN 69871) interfaces on the most recent machines, and SA 50 on historic bed-type machines, with power ratings from 20 to 54 kW depending on the model and rotation speeds typically between 28 and 10,000 rpm.

Frequently asked questions
Do you repair the 5-axis tilting heads of the Arion range?
Yes, we work on these heads, taking into account their fine rotation system and their combined interpolation cycles.
Do you work on the spindles of bed-type milling machines fitted with an SA 50 taper?
Yes, we diagnose and repair these spindles, whether on historic machines or refurbished configurations.
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-dimension heads?
Yes, our team travels to diagnose and, where possible, work directly on site to avoid fully dismantling bulky, heavy heads.
Do you offer a preventive maintenance contract for a fleet of Zayer machines?
Yes, we set up preventive maintenance programmes tailored to your production rate and the criticality of your machines, particularly for aerospace and energy 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 Zayer range — milling heads and spindles for large-format machines — with the responsiveness and rigour demanded by the most exacting industrial environments: aerospace, energy and shipbuilding.
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.
