Thielenhaus spindle and motor spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Thielenhaus spindles and motor spindles — the German manufacturer and international benchmark in microfinishing (superfinishing), known for its four-station hydraulic centring process and its CenterStar platform.
Thielenhaus Microfinish, the German benchmark in precision microfinishing
TLDR: Thielenhaus Microfinish (Germany) is an internationally recognised manufacturer in super-precision technology, notably for its four-station hydraulic centring process, an alternative to the two-station centreless approach of other manufacturers, with the CenterStar platform dedicated to microfinishing shafts between centres.
In the field of super-precision technologies (superfinishing), Thielenhaus of Germany is represented by its four-station hydraulic centring technology, a different approach from the two-station centreless super-precision developed by other manufacturers. The Thielenhaus CenterStar platform is designed for microfinishing and superfinishing shafts mounted between centres, with a modular design allowing almost any type and size of shaft to be machined, whether by tape or stone finishing. Clamping systems include chucks and collets, with or without steady-rest stabilisers, and the manufacturer also offers a special centreless variant of the machine concept. These technologies are particularly sought after in the bearing industry, where reducing waviness and surface roughness is decisive in limiting bearing noise and vibration in service.
A range of spindles and oscillating systems for high-precision microfinishing
TLDR: Thielenhaus machines combine very high speed spindles (up to 60,000 rpm on the reference configurations of the sector) with an oil-stone oscillation system, ensuring excellent vibration resistance and a consistent reduction in surface waviness.
Internationally, super-precision machines generally use 60,000 rpm motor spindles for grinding outer bearing races, with grinding speeds above 60 m/s, a parameter largely limited by the performance of the main spindle bearing. The oil-stone oscillation system specific to Thielenhaus-type super-precision machines offers good vibration resistance, a key factor in achieving good form accuracy and consistent surface texture quality. On the CenterStar platform, whether tape finishing (advantageous for the tightest surface tolerances) or stone finishing (which can positively influence geometry), a form-shoe system can be added to guarantee improved accuracy and surface geometry.

Frequently asked questions
Do you repair the very high speed motor spindles (up to 60,000 rpm) of Thielenhaus machines?
Yes, we work on these spindles, taking into account their specific balancing requirements at very high speed.
Do you work on the spindles of the four-station hydraulic centring system?
Yes, we diagnose and repair these spindles, which are characteristic of Thielenhaus technology.
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 the parts specific to these precision technologies.
Do you work on the spindles of the CenterStar platform for shafts between centres?
Yes, we diagnose and repair these spindles, whatever the clamping system used (chucks, collets, steady rests).
Do you offer a preventive maintenance contract for a fleet of Thielenhaus machines?
Yes, we set up preventive maintenance programmes matched to how critical these precision machines are to your production.
