Waldrich Siegen spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Waldrich Siegen spindles — a historic German manufacturer of gantry milling machines and large-scale roll and cylinder grinding machines, a reference in steelmaking and heavy engineering.
Waldrich Siegen, a German manufacturer of large-scale machines for decades
TLDR: Waldrich Siegen (Germany) is a historic manufacturer specialising in two complementary machine families: gantry milling machines for machining massive prismatic parts (diesel engines, heavy structures), and roll and cylinder grinding machines for the steel and paper industries.
Waldrich Siegen has built a solid reputation manufacturing very large gantry milling machines, capable of machining parts weighing several hundred tonnes, with tables exceeding 15 metres in length on the largest configurations, designed in particular for the production of marine diesel engines and massive mechanical structures. The manufacturer also offers a range of CNC roll and cylinder grinding machines, used in heavy steel and paper industries, capable of handling rolls weighing up to 50 tonnes between centres and several metres in length, with the precision and surface finish essential to the performance of cylinders in their applications.
A range of very high-power milling heads and grinding spindles
TLDR: Waldrich Siegen gantry milling machines feature vertical and side milling heads reaching up to 110 kW, while the cylinder grinding machines use grinding wheel spindles delivering up to 45 kW for grinding massive rolls.
Waldrich Siegen gantry milling machines, such as the Ingersoll models, feature several interchangeable milling heads: vertical crossrail heads delivering up to 110 kW for speeds of 2 to 400 rpm, as well as a horizontal-spindle side milling head reaching up to 70 kW. On configurations dedicated to diesel engine manufacturing, up to 10 different angle milling heads can be fitted to the same machine, with two-range gear spindles (6-200 and 200-600 rpm) and a quill diameter of up to 320 mm. The cylinder grinding machines, meanwhile, feature a grinding wheel spindle delivering up to 45 kW for grinding wheel speeds of 600 to 1,800 rpm, paired with a workhead of around 22 kW for driving the workpiece.

Frequently asked questions
Do you repair the multiple angle milling heads of gantry milling machines?
Yes, we work on these heads, whether vertical crossrail configurations or horizontal-spindle side milling heads.
Do you work on the grinding wheel spindles of roll and cylinder grinding machines?
Yes, we diagnose and repair these spindles, sized for grinding massive workpieces.
What is the average lead time for a complete 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 intervene directly on site for very large heads?
Yes, our team travels to diagnose and, whenever possible, work directly on site to avoid the full disassembly of bulky, heavy heads.
Do you offer a preventive maintenance contract for a fleet of Waldrich Siegen machines?
Yes, we draw up preventive maintenance programmes tailored to your production pace, particularly relevant for steelworks and heavy engineering workshops.
A reliable partner for your industrial performance
Whether it is an emergency on-site intervention, a full workshop overhaul or a preventive maintenance programme, Brochexpress brings its expertise to your production. As an independent workshop, we work across the entire Waldrich Siegen range — milling heads and grinding spindles for large-scale machines — with the responsiveness and rigour demanded by the most exacting industrial environments: steelmaking, paper and heavy engineering.
Our teams are at your disposal from our sites in Beaurepaire (France) and Lussery-Villars (Switzerland) for a study of your needs, a diagnosis or a personalised quotation.
