Junker Group

What Junker Group does

JUNKER Gruppe (Erwin Junker Maschinenfabrik GmbH) is a German, family-owned industrial technology group headquartered in Nordrach and founded in 1962. It develops, manufactures, and sells high-precision grinding machines for the metalworking industry and is recognized as the world market leader in CBN (cubic boron nitride) high-speed grinding, with more than 80 patents covering its core technology. The group operates three wholly-owned entities: Erwin Junker Maschinenfabrik GmbH (grinding machines), LTA Lufttechnik GmbH (industrial air filtration systems, in the group since 1995), and Erwin Jucker Zema Brasil Ltda. (Brazilian operations across two sites), supplemented by Erwin Junker Grinding Technology a.s. for European grinding operations.

The product portfolio spans the full spectrum of precision grinding — round, non-round, worm shaft, centerless, double-disc, cutting-tool, and profile/cut-off grinding machines — alongside the modular Platform 3 architecture and the cost-focused Lean Selection series. Adjacent product categories include the KARGO heavy-shaft grinding platform for wind power and LTA electrostatic and mechanical filtration systems for coolant-mist and dust removal. The company monetizes hardware sales of capital equipment, a 24/7 worldwide premium service network (maintenance, parts, repairs, training, startup), and an RETROFiT aftermarket program covering retooling, overhauls, and upgrades for control, process, energy, measurement, and preventive maintenance, plus a pre-owned machine resale channel.

JUNKER serves primarily enterprise customers across automotive (crankshafts, cam shafts, transmission components), the tool industry (threaded tools, cutting instruments), aerospace (bearings, rollers), wind power (gear shafts up to 5,000 mm / 5,000 kg), and emerging segments such as humanoid robotics. Go-to-market is exclusively direct enterprise field sales supported by 11 global locations and major industry trade shows (IMTS, GrindingHub, EMO), with quote-based, multi-year custom-contract pricing reflecting the configuration complexity of each installation. The group employs more than 1,100 people worldwide and operates with no external investors or parent company, consistent with the German Mittelstand model.
