SNK spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of SNK (Shin Nippon Koki) spindles and motor spindles — a Japanese manufacturer specialising in large-scale gantry milling machines and titanium machining centres.
SNK, a Japanese giant in large-scale gantry milling machines
TLDR: SNK (Shin Nippon Koki, Japan) is a major player in the machine tool industry, specialising in 5-axis milling machines, with a range covering machining centres, turn-mill centres and gantry-type centres, for travels of up to 100 metres.
SNK is a Japanese company specialising in 5-axis machining, producing robust and innovative machining centres, turn-mill centres and gantry-type centres. The technology on offer varies, with vertical or horizontal configurations, particularly for very large dimensions — a genuine speciality of the Japanese manufacturer. The HGM range of 5-axis gantry milling machines covers X-axis travels from 6,500 mm up to 100,000 mm, with Y-axis travels of 2,500 to 4,000 mm and Z-axis travels of 1,000 or 1,500 mm depending on requirements, enabling exceptional parts to be machined for aerospace, automotive and precision engineering. SNK is also recognised for its horizontal machining centres dedicated to titanium machining, with the HPS, GHP and CMV ranges designed for horizontal configurations.
A range of high-speed motor spindles for titanium machining and large-format parts
TLDR: SNK gantry milling machines (HGM range) feature motor spindles reaching up to 20,000 rpm, with a rigid construction guaranteeing repeatability and precision over exceptional travels, suited to aluminium, steel and composite materials.
SNK's 5-axis gantry milling centres, HGM range, are fitted with a motor spindle capable of reaching 20,000 rpm, delivering high machining speed and high productivity on parts of various sizes. Thanks to a rigid construction and the use of high-quality components, these machines ensure exceptional repeatability, minimising margins of error even over travels of up to 100 metres. The material versatility of these spindles allows work on aluminium, steel and composite materials, while the horizontal centres dedicated to titanium benefit from spindles specifically sized for this demanding material.

Frequently asked questions
Do you repair motor spindles on gantry milling machines from the HGM range?
Yes, we work on these spindles, up to 20,000 rpm, regardless of the machine's travel length.
Do you work on spindles from horizontal machining centres dedicated to titanium?
Yes, we diagnose and repair these spindles, taking into account the specific requirements of machining this material.
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 intervene directly on site for very large spindles?
Yes, our team travels to diagnose and, where possible, intervene directly on site to avoid the complete dismantling of bulky, heavy spindles.
Do you offer a preventive maintenance contract for a fleet of SNK machines?
Yes, we draw up preventive maintenance programmes tailored to your production rate, particularly relevant for aerospace 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 SNK range — motor spindles for gantry milling machines and spindles for large-format horizontal machining centres — with the responsiveness and rigour demanded by the most exacting industrial environments: aerospace, automotive and precision engineering.
