YCM spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of YCM (Yeong Chin Machinery) spindles and motor spindles — a Taiwanese manufacturer founded in 1954, the first Taiwanese builder certified ISO 9001, a reference in machining centres and CNC lathes.
YCM, more than 70 years of Taiwanese excellence in machine tools
TLDR: YCM (Yeong Chin Machinery Industries, founded in 1954, Taiwan) is the first Taiwanese manufacturer to have received the ISO 9001 quality assurance certificate, recognised worldwide for the exceptional accuracy, rigidity and reliability of its machines.
Founded in 1954, YCM originally built special-purpose machines before releasing its very first machining centre in late 1982, a genuine turning point in its history. The first Taiwanese manufacturer certified ISO 9001, YCM drew on the Toyota production system to develop its own production method, based on customer service, new technologies and quality materials. Fully vertically integrated in its own manufacturing facility, the builder offers a complete range covering vertical, horizontal and double-column machining centres, as well as turning centres and multi-axis lathes, serving demanding sectors: mould making, aerospace, automotive and medical devices.
A range of high-speed BBT40 spindles and multi-axis turning spindles
TLDR: YCM machining centres use BBT40 interface spindles, with rotation speeds reaching 12,000 to 15,000 rpm for 25 to 37 kW, while turning centres offer configurations with live tooling, sub-spindle and Y axis.
YCM vertical machining centres (NSV series) use BBT40 interface spindles, with rotation speeds reaching 12,000 rpm as standard and up to 15,000 rpm as an option, for power ratings of 25 to 37 kW depending on the configuration. Horizontal machining centres, designed for optimal chip evacuation and high thermal stability, use robust spindles suited to complex multi-axis machining capabilities. YCM turning centres offer high-precision turning operations with advanced features such as live tooling, sub-spindle and Y-axis capability, for complete machining in a single setup.
YCM spindles covered (non-exhaustive list)
- BBT40 spindles, up to 15,000 rpm, NSV series vertical machining centres
- Spindles of horizontal machining centres with high thermal stability
- Spindles of double-column (gantry) machining centres
- Spindles of lathes with live tooling, sub-spindle and Y axis
- Spindles of high-speed 5-axis machining centres for mould making
Interfaces and specifications
The YCM spindles and motor spindles we repair mainly use a BBT40 interface, with rotation speeds typically between 12,000 and 15,000 rpm and power ratings of 25 to 37 kW depending on the model.

Frequently asked questions
Do you repair the BBT40 spindles of NSV series vertical machining centres?
Yes, we work on these spindles, whatever the configured rotation speed (up to 15,000 rpm).
Do you work on the spindles of lathes with sub-spindle and Y axis?
Yes, we diagnose and repair these spindles, taking into account their live tooling configuration.
What is the average lead time for a full 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 on the spindles of double-column machining centres?
Yes, we diagnose and repair these spindles, sized for machining large parts.
Do you offer a preventive maintenance contract for a fleet of YCM machines?
Yes, we draw up preventive maintenance programmes tailored to your production pace.
