Soraluce spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Soraluce spindles and milling-boring heads — a Spanish manufacturer within the Danobat group, recognised for its large-capacity milling-boring machines intended for energy, marine and heavy engineering.
Soraluce, over 50 years of expertise in large-capacity milling-boring
TLDR: Soraluce (Danobat group, Spain, over 50 years of experience) designs milling-boring machines and multitasking machining centres in fixed-bed, travelling-column and gantry configurations, combining milling, boring, drilling, vertical turning and grinding for medium and large workpieces.
For over 50 years, Soraluce has developed a range of high-precision milling-boring machines designed to meet the specific needs of demanding sectors: energy, marine, mining, capital goods and industrial vehicles. The manufacturer offers varied architectures — fixed bed, travelling column, portal and gantry, multitasking double-column machines — making it possible to combine milling, boring, drilling, vertical turning and grinding on a single machine. The travelling-column models of the FP/FR/FLP/SLP range integrate advanced technologies on the axes and spindles, including the DAS adaptive control, while the multitasking PM/PMG/PRG/PXG machines offer high material-removal capacity for machining prismatic parts in a single set-up.
A range of heads and spindles for heavy machining and multitasking
TLDR: Soraluce spindles come with an ISO 50 taper, with orthogonal milling heads directly driven by a high-torque motor, capable of inverted machining down to -45° and simultaneous positioning of both articulations to minimise downtime.
Soraluce travelling-column milling-boring machines are fitted with main spindles offering axial travel, integrated into the machine's ram, available depending on the model in shaft diameters from Ø130 to Ø150 mm and compatible with automatic head-changing systems. The compact orthogonal head, specially designed for direct-drive machines, allows simultaneous positioning of both articulations and an inverted machining capacity down to -45°, with optimised spindle accessibility in both frontal and lateral positions. On multitasking double-column machines, suitable milling and turning heads cover a wide range of operations on large workpieces.
Soraluce heads and spindles covered (non-exhaustive list)
- Main spindles with axial travel, integrated into the ram, ISO 50 taper
- Compact direct-drive orthogonal heads, simultaneous positioning of both articulations
- Special angular heads for railway applications (bogies) and engines
- Interchangeable milling-boring heads, automatic changing system
- Spindles for multitasking milling/turning machines, PM/PMG/PRG/PXG range
Interfaces and specifications
The Soraluce spindles we repair come mainly with an ISO 50 interface, with spindle shaft diameters typically between Ø130 and Ø150 mm depending on the model, power ratings in the region of 32 kW and rotation speeds of up to 4,000 to 5,000 rpm on the most dynamic configurations.

Frequently asked questions
Do you repair compact direct-drive orthogonal heads?
Yes, we work on these heads, taking into account their simultaneous two-articulation positioning system specific to Soraluce.
Do you work on the spindles of multitasking milling/turning machines?
Yes, we diagnose and repair both milling and turning spindles on the PM, PMG, PRG and PXG double-column 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 spindles?
Yes, our team travels to diagnose and, where possible, work directly on site in order to avoid the full removal of bulky, heavy spindles.
Do you offer a preventive maintenance contract for a fleet of Soraluce machines?
Yes, we set up preventive maintenance programmes tailored to your production rate, particularly relevant for energy and marine 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 Soraluce range — milling-boring heads and spindles for large machines — with the responsiveness and rigour demanded by the most exacting industrial environments: energy, marine and heavy engineering.
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.
