Wotan spindle and motorized spindle repair
Brochexpress is an independent workshop specialising in the repair, maintenance and diagnostics of Wotan spindles and motorized spindles — a historic German manufacturer of horizontal boring mills, a classic reference alongside Union, Skoda and Pama for machining large-size parts.
Wotan, historic German manufacturer of horizontal boring mills
TLDR: Wotan is a historic name in German horizontal boring mill construction, regularly cited among the sector's leading reference manufacturers alongside Union, Skoda, Pama, Juaristi and Scharmann, with machines still widely present in European heavy engineering shops.
Wotan is among the most recognised historic names in German horizontal boring mill construction, alongside manufacturers such as Union, Skoda, Pama, Juaristi and Scharmann. Its table-type boring mills, such as the referenced Wotan 6000 model, feature robust configurations with a rotary table, tool changer and interchangeable angle milling heads, allowing multi-face machining of large-size parts in heavy mechanical engineering. These machines, although old for many of them, remain widely represented in European workshops and continue to require rigorous maintenance of their spindles to preserve machining accuracy.
A range of robust ISO 50 taper spindles for the horizontal boring-milling machine
TLDR: Wotan boring mills feature a retractable main spindle with an ISO 50 taper, with a diameter of up to 130 mm and rotation speeds typically around 2,000 rpm, combined with interchangeable angle milling heads.
Wotan horizontal boring mills feature a retractable main spindle with an ISO 50 taper, with a spindle diameter of up to 130 mm, for typical rotation speeds in the order of 2,000 rpm. These machines are generally fitted with a rotary table (for example 1,800 x 1,400 mm), a W axis travel of several metres and a tool changer of up to 60 stations. Two additional angle milling heads frequently equip these configurations, allowing multi-face machining of massive parts without re-clamping.
