What Index Corporation does

Index Corporation is the US operating entity of INDEX-Werke GmbH & Co. KG Hahn & Tessky, a German-headquartered manufacturer of CNC turning machines with operations spanning roughly 110 years. The company designs, manufactures, and sells a broad portfolio of CNC turning equipment — including turn-mill centers (G160 through G520, R200, R300), production turning machines (C100, C200, ABC), multi-spindle machines (MS series plus TRAUB MS12-4), and sliding headstock machines (TRAUB TNL12, TNL20) — marketed under the INDEX and TRAUB brands alongside an intelligent automation solutions range (bar loaders, robotic integration, custom cells) and the proprietary iXpanel Industry 4.0 operating system.

The underlying technology combines Siemens, FANUC, and TRAUB CNC controllers with proprietary programming and simulation software, plus specialized technology packages such as gearing technology, polygon turning, high-speed whirling, grinding technology, CenterMaster, and ClampMaster. Customer-facing digital infrastructure includes the iXshop online parts platform, the iXworld digital ecosystem, and the iX4.0 Industry 4.0 solutions suite, complemented by an iXservices aftermarket offering spanning machine check, spare parts, maintenance, repair, retrofit, refit, process support, training, and financing.

Revenue is generated primarily through quote-based hardware sales (per-machine pricing varies by spindle clearance, chuck diameter, turning length, torque, and automation options) with multi-year contract cadence on enterprise orders. Go-to-market is direct enterprise field sales supported by 7 international sales and service companies, supplemented by an extensive world-class distributor network across 80 global sites in markets including the US, Germany, France, Sweden, Russia, China, Brazil, and Spain. Served verticals are aerospace (aircraft structures, landing gear, propulsion components), medical (devices, surgical instruments, implants), and e-mobility (EV drive components, wheel components, power train parts). Pricing is not publicly disclosed and engagement requires direct sales contact.
