Juaristi boring machine spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Juaristi boring machine spindles — a Basque Spanish manufacturer founded in 1943 and one of the most internationally recognised brands for large-capacity boring machines and milling centres.
Juaristi, a reference Basque manufacturer since 1943
TLDR: Juaristi (Basque Country, Spain, machine tool manufacturer since 1943) specialises in large-capacity boring machines and milling/machining centres, with travel ranges of up to 6,000 x 3,000 mm, and ranks among the most internationally recognised Spanish brands.
A machine tool manufacturer since 1943, the year it launched its first boring machine, Juaristi has specialised in precision machinery, with an appealing range of large-capacity machining and milling centres reaching dimensions of up to 6,000 x 3,000 mm. The Basque Spanish manufacturer is today one of the most internationally recognised brands in this sector. Its fixed-column, moving-table boring machines, such as the MD series, enable the machining of heavy workpieces weighing several tonnes, with motorised rotary tables and generous travel on all three axes.
A range of large-bore spindles and orthogonal automatic heads
TLDR: Juaristi boring machines feature ISO 50 taper spindles, with diameters of up to 110 to 130 mm, paired with orientable orthogonal automatic heads (typically at 2.5° x 2.5° increments) delivering power ratings of up to 30 kW.
Juaristi CNC boring-milling machines, such as the MD or TS series, feature ISO 50 taper spindles, with diameters typically ranging from 110 to 130 mm, rotating at speeds of around 3,000 rpm. An orthogonal automatic head, orientable in 2.5° increments on two axes, delivers up to 30 kW of power at 2,500 rpm, enabling multi-face machining of large workpieces. These machines are generally fitted with ball screws on all four axes and can incorporate a motorised facing plate for large-diameter operations.

Frequently asked questions
Do you repair the orientable orthogonal automatic heads of Juaristi boring machines?
Yes, we work on these heads, taking into account their 2.5° step orientation system.
Do you work on large-bore spindles (110 to 130 mm)?
Yes, we diagnose and repair these spindles, whatever the diameter involved.
What is the average lead time for a complete 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 directly on site for large-size spindles?
Yes, our team travels to diagnose and, whenever possible, work directly on site to avoid the full disassembly of bulky, heavy spindles.
Do you offer a preventive maintenance contract for a fleet of Juaristi machines?
Yes, we draw up preventive maintenance programmes tailored to your production pace, particularly relevant for general engineering 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 Juaristi range — boring machine spindles and orthogonal automatic heads for large-capacity machines — with the responsiveness and rigour demanded by the most exacting industrial environments.
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.
