Litz spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Litz (Litz Hitech) spindles and motor spindles — a Taiwanese manufacturer from Taichung, specialising in high-speed 5-axis vertical machining centres.
Litz Hitech, Taiwanese builder of high-speed 5-axis centres
TLDR: Litz Hitech Corp. (Taichung, Taiwan) designs 3- and 5-axis vertical machining centres, with a flagship LU range featuring swivelling B/C axes, intended both for mass production and for precision machining of complex parts.
Based in Taichung, Litz Hitech develops CNC vertical machining centres known for their compact, stable structure, high-technology components and high cutting performance. The flagship LU range (LU-400, LU-620, LU-1200B) is built on a high-rigidity cast iron base supporting swivelling B/C axes, with a cross-slide design on the Y axis guaranteeing maximum machining accuracy, quality stability and production efficiency. These 5-axis centres serve mass production as well as precision machining applications, with tool changers of up to 24 to 30 stations and very short tool change times (around 3 seconds).
A range of direct-drive motor spindles with thermal isolation
TLDR: Litz machining centres use direct-drive motor spindles that isolate the motor heat source, with rotation speeds reaching 12,000 to 20,000 rpm in BT40 interface, together with oil-temperature cooling control for greater accuracy.
Litz motor spindles are built on a direct-drive design between motor and spindle, isolating the motor heat source to reduce thermal displacement and improve spindle accuracy and service life. A thermally isolated coupling between motor and spindle, combined with oil-temperature cooling control, delivers higher precision control without the noise, backlash or vibration issues associated with belt or gear drives. On LU-620 models, the standard spindle reaches 12,000 rpm in taper 40, while the most dynamic configurations can reach 20,000 rpm, with power ratings of 27 to 37 kW and maximum torque of 400 Nm in #50/HSK100A interface on higher-capacity models (LU-1200B).
Litz spindles covered (non-exhaustive list)
- Direct-drive motor spindles, up to 20,000 rpm
- BT40 spindles, LU series 5-axis machining centres (LU-400, LU-620)
- #50/HSK100A spindles, up to 37 kW, LU-1200B series
- Spindles with oil-temperature cooling control
- Spindles of fixed-column vertical machining centres, MV series
Interfaces and specifications
The Litz spindles and motor spindles we repair mainly use BT40 and #50/HSK100A interfaces, with rotation speeds typically between 12,000 and 20,000 rpm depending on the model, for power ratings of 27 to 37 kW.

Frequently asked questions
Do you repair the direct-drive motor spindles of LU series 5-axis centres?
Yes, we work on these spindles, taking into account their thermal isolation system.
Do you work on the #50/HSK100A spindles of higher-capacity centres (LU-1200B)?
Yes, we diagnose and repair these spindles, whatever the configured power.
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 spindles fitted with oil-temperature cooling control?
Yes, we diagnose and repair these spindles, essential to the accuracy and service life of the machine.
Do you offer a preventive maintenance contract for a fleet of Litz machines?
Yes, we draw up preventive maintenance programmes tailored to your production pace.
