TDM

What TDM does

TDM SA (TDM Spindles SA) is a Swiss precision engineering company founded in Caslano, Switzerland (Canton Ticino), specializing in the design and manufacture of high-frequency motor spindles and proprietary asynchronous and synchronous electric motors. The company offers approximately 20 years of experience in spindle and motor development, with a product portfolio organized around five core lines: Electrospindles (milling, grinding, adaptor, special, micro, and belt-driven variants), Multi-Tools (compact systems with ~2-second chip-to-chip tool changes), Hydrostatic Elements (ultra-precision spindles with rotational accuracy down to 10 nanometers and speeds up to 250,000 rpm), Rotation Axes (B-axis devices for machining centers), and standalone Motors. All design and components are developed in-house, enabling custom-made solutions for applications requiring nanometer-level tolerances, high torque at speed, and virtually unlimited bearing life via hydrostatic bearing technology.

The company sells to machine tool OEMs and precision manufacturers across seven primary verticals — watchmaking, automotive, aerospace/aviation, railway, medical, dental, and electronics — with use cases ranging from engine block and gearbox milling to smartphone mold polishing and dental implant machining. The go-to-market is event-driven, anchored by regular participation in the world's leading machine tool exhibitions (EMO Hannover, TIMTOS, AMB Stuttgart, SIAMS Moutier, SIMTOS Korea), supplemented by wholly-owned regional offices in the USA (TDM USA, Inc., Meriden, CT), Taiwan (Taichung City), and Korea (T-Solution, Seoul). The revenue model is hardware sales of custom-engineered spindles and motors, complemented by after-sale reconditioning services that restore units to equal-to-new condition with new guarantee, generating a recurring service revenue stream tied to the installed base. Pricing is quotation-based given the bespoke nature of products serving aerospace, automotive, watchmaking, medical, and other precision manufacturing sectors.
