What Kellenberger does

Kellenberger is a Swiss precision machine tool manufacturer founded in 1917 and headquartered in Goldach, Switzerland. Following a 2025 corporate restructuring that transformed Kellenberger Investment Holding into the operational Kellenberger Machines Holdings GmbH, the company designs and produces high-precision CNC grinding, turning, and milling machines under the unified Kellenberger brand and five heritage technology sub-brands (HAUSER, SUPER-PRECISION, TSCHUDIN, VOUMARD, USACH). The product portfolio spans cylindrical OD grinding (K8/K10/K100/K1000), internal diameter grinding (VM30, VM1000, U300, Hydrolin), jig grinding (H2000, H4000), hard turning (SP42/SP51/SP65), 5-axis turning and milling (TM300), and multi-function machining (T1000), complemented by automation systems (A9000 FLEX, A900, A90 FLY, A90 REX) and a proprietary software ecosystem (BLUE Solution with gSET/gTIME/gSHAPE/gMEASURE/gTOUCH modules, BLACK CAM, WHITE, FLEX Turnkey, ComGateway OPC UA server, MGi programming). Controls are sourced from Siemens (SINUMERIK ONE) and FANUC (30i-B).

The company operates a direct enterprise field sales motion through wholly-owned subsidiaries across four regions: Europe (Goldach/Reutlingen), China (Shanghai manufacturing and sales), America (Elgin, Illinois engineering/R&D since 1975), and Rest of World (Kuala Lumpur, India), supported by attendance at five major trade fairs (AMB, IMTEX, GrindingHub Americas, EMO, BI-MU). Revenue is generated through four streams: capital equipment sales (grinding, turning, milling machines), proprietary software (one-time licenses bundled with machines), service contracts in tiered models (Economy, Advantage, Relax) covering training, maintenance, retrofits, and spare parts, and a digital service platform (myKellenberger) for 24/7 customer self-service. Target verticals include mechanical engineering, automotive and EV suppliers, aerospace, medical technology, defense, energy, electrical industry, tool grinding, and tool/mold making. The company holds ISO 9001:2015 certification and employs 101–250 staff globally.
