Willemin-Macodel spindle and motor spindle repair
Brochexpress is an independent workshop specializing in the repair, maintenance and diagnostics of Willemin-Macodel spindles and motor spindles — a Swiss Jura manufacturer that is a benchmark in high-precision micro-machining, dedicated to watchmaking, medical, dental and micro-mechanics.
Willemin-Macodel, a Swiss benchmark in high-precision micro-machining
TLDR: Willemin-Macodel (Delémont, Swiss Jura, a family business founded in 1974) designs high-precision facing lathes and multiprocess machining centres, initially for watchmaking and then diversified towards medical, dental, aerospace and micro-mechanics.
Founded in 1974 in the Swiss Jura, Willemin-Macodel first grew in the watchmaking sector before diversifying towards medical, aerospace, dental, mould-making and advanced micro-mechanics. The company, which celebrated its 50th anniversary in 2024, designs and manufactures its own spindles and indexing units in-house, which allows it to master each machine end to end. Its range spans vertical-spindle machining centres dedicated to milling watch plates, multiprocess centres combining turning and milling in a single cycle, as well as the 701S machining centre, the first equipment to use Delta-type parallel kinematics to achieve submicron machining conditions, with a motor spindle able to reach up to 80,000 rpm.
A range of motor spindles and indexing spindles designed in-house
TLDR: Willemin-Macodel equips its multiprocess centres with swivelling motor spindles mounted on a B axis combined with high-precision indexing spindles on an A axis, making it possible to combine turning (up to 6,000 rpm) and milling with high angular resolution.
Willemin-Macodel multiprocess machining centres, such as the 408 and 508 ranges, integrate a swivelling motor spindle mounted on a B axis, combined with a high-precision indexing spindle on an A axis, allowing work in both turning mode (up to 6,000 rpm on standard configurations) and milling mode with high angular resolution. The linear-axis models using "Full Linear" technology (501S2, 508S2) fit all their linear and rotary axes with direct-drive motors for enhanced precision and thermal stability. On the 701S centre, dedicated to ultra-precise micro-machining, the Delta-kinematics motor spindle reaches rotation speeds of up to 80,000 rpm, with the tools fixed directly in the motor spindle to maximise machining precision.
Willemin-Macodel spindles covered (non-exhaustive list)
- Vertical spindles of machining centres dedicated to milling watch plates
- Swivelling B-axis motor spindles, turning/milling multiprocess centres
- High-precision A-axis indexing spindles

Frequently asked questions
Do you repair the ultra-high-speed Delta-kinematics motor spindles of the 701S?
Yes, we work on these motor spindles, taking into account their specific submicron precision requirements and their high rotation speed.
Do you work on the swivelling B-axis motor spindles of the multiprocess centres?
Yes, we diagnose and repair these motor spindles as well as the associated A-axis indexing spindles.
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 specific to these precision technologies.
Can a repair affect the submicron precision guaranteed by Willemin-Macodel?
Our overhaul process aims to restore the manufacturer's original tolerances, with particular care given to balancing and bearing clearances, which are essential on this type of spindle.
Do you offer a preventive maintenance contract for a fleet of Willemin-Macodel machines?
Yes, we set up preventive maintenance programmes tailored to the criticality of this equipment, particularly relevant for watchmaking and micro-mechanics workshops.
