Heller

What Heller does

Heller (legal name: Gebr. Heller Maschinenfabrik GmbH) is a German manufacturer of CNC machine tools and complete manufacturing systems for metal cutting, founded in 1894 in Nürtingen, Germany, and now operating as a wholly-owned subsidiary of South Korea's DN Solutions Co., Ltd. following the January 2026 acquisition. The company designs and produces horizontal machining centers organized into three core series — the 4-axis H-series, the 5-axis HF-series (5th axis in the workpiece), and the 5-axis F-series (5th axis in the tool, including the F 5000 through F 16000) — alongside specialized machines for structural parts (WV 8000), big castings (WH 10000), crankshaft and camshaft production systems, and transfer line systems (TRS). Differentiated components include in-house-developed spindles and swivel heads, and the machines integrate the Siemens SinUMERIK ONE control with Heller's HELLER Operation Interface and a digital twin for process simulation and error prevention.

Heller generates revenue primarily through one-time capital equipment sales of custom-configured CNC machining centers to enterprise customers, supplemented by a Lifetime Partnership service model that includes spare parts, hotline support, retrofits, retrofits, training, and component repair across the machine lifecycle. Increasingly, the company is layering on subscription-style digital services — ASK.me (an AI chatbot for operator support), the HELLER Services Interface (HSI) for production and predictive maintenance analytics, HELLER4Industry (Remote Diagnostics and Advanced Data Box), and the myHELLER customer portal — sold alongside machines or as modular add-ons. Customer concentration is in automotive (the historical core, serving OEMs and Tier 1s on engine, transmission, and chassis components) and aerospace (growing emphasis on titanium, Inconel, and superalloy structural parts and aero-engine components), with additional sales into general industrial machinery, heavy industrial, and specialized segments like food processing and pharmaceutical equipment. Go-to-market is direct enterprise field sales supported by a global network of own sales and service subsidiaries and, post-acquisition, DN Solutions' 140+ distribution partners across 66 countries, complemented by industry trade shows (EMO, IMTS, AMB, Farnborough, Paris Air Show) and the Ready4productivity stock-machine program.

Core offering

Heller manufactures and sells horizontal CNC machining centers (4-axis F-series and 5-axis Fmax-series), crankshaft and camshaft production machines (CP/CPK lines), and fully automated flexible manufacturing systems (FFS/MCS) that combine machines, automation, and tooling into turnkey production cells. Customers are predominantly automotive OEMs/Tier-1 suppliers and aerospace/industrial manufacturers requiring high-output, lights-out serial production.

Product overview

Heller is a manufacturer of CNC machine tools and complete manufacturing systems for metalworking. The product portfolio consists of horizontal machining centers organized into three core series: the H-series (4-axis), HF-series (5-axis with 5th axis in workpiece), and F-series (5-axis with 5th axis in tool). The F-series includes models F 5000 through F 16000 for applications ranging from general machining to large aerospace structural parts. Additional specialized machines include the WV 8000 vertical machining center for structural components, the WH 10000 for large aluminum castings, crankshaft/camshaft production systems, and transfer line systems for automotive series production. Automation solutions cover pallet, workpiece, and tool automation. Digital services include the ASK.me AI chatbot, HELLER Services Interface (HSI) for production data visualization, HELLER4Industry (Remote Diagnostics, Advanced Data Box), and the myHELLER customer portal. Assist systems (SETUP-Assist, PRODUCTION-Assist, QUALITY-Assist) and the TOKn 5-axis training machine complete the portfolio. Since January 2026, Heller has been part of DN Solutions (Korea).
