Sachman spindle, motorized spindle and milling head repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Sachman spindles and motorized spindles, together with their milling heads — an Italian manufacturer of travelling-column boring-milling machines and large machining centres, strongly present in aerospace, automotive and heavy mechanical engineering.
Sachman, Italian manufacturer of large-size boring-milling machines
TLDR: Sachman (Italy) designs travelling-column boring-milling machines and large machining centres, with ranges covering travels of several metres, aimed at the aerospace, automotive, energy and mechanical engineering sectors.
Sachman offers a complete range of travelling-column boring-milling machines and universal machining centres, with configurations reaching longitudinal travels of 6,000 to 8,000 mm on the largest models (PX, MX and T series). T series machines, with a pallet changer and an automatic bi-rotary head, are particularly suited to the production of complex parts in medium-sized batches, with table travels of up to 3,500 x 1,600 x 2,000 mm. Sachman machines equip demanding workshops in aerospace, automotive, energy, mechanical engineering and marine industries.
A range of bi-rotary milling heads and high-speed spindles
TLDR: Sachman boring-milling machines feature ISO 50 taper spindles with automatic bi-rotary heads (typically 2.5° x 2.5°), for powers from 15 to 31.5 kW, with the option of additional high-speed spindles reaching 30,000 rpm on certain configurations.
Sachman boring-milling machines feature ISO 50 (SK 50) taper spindles, with rotation speeds typically between 10 and 6,000 rpm depending on the model, for powers from 15 to 31.5 kW. The automatic bi-rotary head, orientable in 2.5° steps on two axes (A and C), equips the most advanced configurations, with high-pressure through-spindle coolant of up to 15 bar. On travelling-column centres dedicated to high-speed machining, an adaptable additional spindle can reach up to 30,000 rpm for finishing operations on light alloys.
Sachman spindles covered (non-exhaustive list)
- ISO 50 (SK 50) spindles, automatic bi-rotary heads 2.5° x 2.5°
- Travelling-column boring-milling machine spindles, PX, MX and T series
- Additional high-speed spindles, up to 30,000 rpm
- Spindles of centres with pallet changers
- Historic fixed-bed milling machine spindles, R/RP series
Interfaces and specifications
The Sachman spindles we repair are mainly ISO 50 (SK 50) interface spindles, with rotation speeds typically between 10 and 6,000 rpm, and additional high-speed spindles reaching 30,000 rpm on certain configurations.

Frequently asked questions
Do you repair the 2.5° x 2.5° automatic bi-rotary heads of Sachman milling machines?
Yes, we work on these heads, taking into account their orientation system.
Do you work on additional high-speed spindles (up to 30,000 rpm)?
Yes, we diagnose and repair these spindles, dedicated to light alloy finishing.
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 dismantling of bulky and heavy heads.
Do you offer a preventive maintenance contract for a fleet of Sachman machines?
Yes, we draw up preventive maintenance programmes tailored to your production pace, particularly relevant for aerospace and automotive 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 all Sachman spindles and motorized spindles, milling heads included — large-size boring-milling machines — with the responsiveness and rigour demanded by the most exacting industrial environments: aerospace, automotive and energy.
