UNION

What UNION does

UNION is a product brand of horizontal boring mills, not an independent operating company. The brand sits inside WaldrichSiegen, the German specialist for heavy-duty machine tools within the HerkulesGroup, and the products are manufactured at the WaldrichSiegen facility in Siegen, Germany. UNION boring mills are heavy-duty horizontal machines designed for precision boring and milling of large-scale industrial workpieces, and the brand is positioned as WaldrichSiegen's specialist boring-machining offering alongside a broader portfolio that includes ProfiMill portal milling machines, ProfiTurn H/M/V turning and mill-turning lathes, ProfiGrind roll grinding machines, ProfiTex texturing machines, and integrated Roll Shop solutions.

The brand targets three named industrial verticals: energy technology, heavy mechanical engineering, and roll manufacturers. Customers in these segments require precision machining of large components with tight tolerances, typically for power generation equipment, large structural parts, and metal processing rolls. Sales are conducted on a direct, enterprise basis through the WaldrichSiegen/HerkulesGroup field sales channel, with technical consultation and custom configuration for each application. Pricing is not publicly disclosed and is quote-based, consistent with the custom-engineering nature of heavy capital equipment.

Commercially, UNION relies entirely on the HerkulesGroup ecosystem for go-to-market, distribution, and aftermarket service, including a US footprint through the Herkules site in Ford City. No standalone financial information (revenue, headcount at the brand level, funding, or management team) is disclosed, and the unionchemnitz.com web reference and Chemnitz city entry in the firmographic data appear to reflect historical brand heritage rather than the current production location. The brand's strategic role within the group is to provide a focused, recognizable boring-mill specialist label that complements the group's other specialized machine tool brands.
