Mikron spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Mikron spindles and motor spindles — the Swiss manufacturer founded in 1908 in Biel, a pioneer of involute hobbing machines, whose gear cutting business joined Gleason-Pfauter Switzerland.
Mikron, Swiss gear cutting pioneer since 1908
TLDR: Mikron AG, founded in 1908 in Biel by the watchmaker Karl Lüthy, began by building involute hobbing machines and small-gear forming machines for the Swiss watchmaking industry, before diversifying and seeing its gear cutting division join the Pfauter group and then Gleason.
Founded in 1908 in Biel by the watchmaker Karl Lüthy, Mikron AG initially produced toolroom lathes, involute hobbing machines (series 102) and small-gear forming machines for the watchmaking industry. These early gear cutting machines contributed substantially to the industrialisation of Swiss watchmaking in the early twentieth century. In 1994, the Mikron gear cutting business in Biel was acquired by the Pfauter group, leading to the creation of Gleason-Pfauter Switzerland, today Gleason Switzerland AG. The Mikron 102 hobbing machines (in 102.03, 102.04 and 102.05 versions) remain in use today in small-mechanics and watchmaking workshops.
A range of synchronised hob and workpiece spindles for generating
TLDR: Mikron 102 hobbing machines use a hob spindle and a workpiece spindle whose perfectly synchronised rotation is essential to generating, with an additional phase shift for producing helical gears.
On Mikron 102 generating hobbing machines, a hob spindle works in perfect rotational synchronism with a workpiece spindle (the equivalent of a dividing head), a prerequisite for correctly cutting any tooth count on a straight or helical gear with a single cutter of a given module. For cutting helical gears, an additional synchronism phase shift is added in proportion to the cutter feed, a kinematic principle comparable to that of a worm and its rotating worm wheel. These manual machines, robust and accurate, remain in service today in small-mechanics workshops.

Frequently asked questions
Do you repair the hob and workpiece spindles of Mikron 102 hobbing machines?
Yes, we work on both spindles, taking care to preserve their perfect synchronisation.
Do you work on historic Mikron hobbing machines still used in small mechanics?
Yes, we diagnose and repair the spindles whatever the age of the machine.
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 dedicated to cutting helical gears with a synchronism phase shift?
Yes, we diagnose and repair these spindles, whatever the helix angle required.
Do you offer a preventive maintenance contract for a fleet of Mikron machines?
Yes, we draw up preventive maintenance programmes tailored to your production pace.
