HELLER

What HELLER does

HELLER is a German manufacturer of CNC horizontal machining centers and integrated production systems for industrial metal cutting, headquartered in Nürtingen and founded in 1894. Its core product range spans 4-axis machining centers (H Series), 5-axis horizontal centers with the fifth axis in the workpiece (HF Series), and 5-axis centers with the fifth axis in the tool (F Series), supplemented by the WV 8000 structural component center, the WH 10000 Big Casting center, crankshaft/camshaft production systems, and TRS transfer line systems. A core technical differentiator is the in-house development and manufacture of key components — spindles and swivel heads — that other machine builders typically source externally. The digital layer branded HELLER4Industry adds AI-assisted services including the ASK.me chatbot, the HELLER Services Interface (HSI) for predictive maintenance, SETUP/PRODUCTION/QUALITY-Assist modules, digital twin simulation, and the myHELLER customer portal.

HELLER generates revenue primarily through one-time capital equipment sales to industrial OEMs, with a growing aftermarket services stream covering spare parts, field service, retrofits, training, financing, and insurance. Its primary vertical is automotive (engine blocks, cylinder heads, transmissions, chassis), with aerospace, general engineering, energy technology, fluid technology, agriculture and construction machinery, job shops, and education as secondary segments. Distribution is via owned sales and service subsidiaries in Germany, France, Italy, Spain, UK, USA, China, Brazil, and Argentina, supplemented by a global service partner network.

In January 2026, DN Solutions — Korea's machine tool market leader and the world's third-largest machine tool manufacturer — completed the acquisition of HELLER for approximately USD 176 million, following a prior H.I.G. Capital agreement that was superseded. The combined entity is projected to generate approximately EUR 2 billion in consolidated revenue and produce over 13,400 machines annually, with HELLER retaining its brand identity and German headquarters while integrating into the parent's Korean-led commercial channels.
