What SIEB & MEYER USA does

SIEB & MEYER USA is a privately held US subsidiary of German parent SIEB & MEYER AG, headquartered in Dayton, Ohio, that designs, manufactures, and services motion control systems, CNC controls, and drive electronics for industrial machinery. The company's roots trace to 1972 when it began as a division of General Automation with one of the first microprocessor-based CNC controls, and it has maintained a core team of software engineers from that era who continue to refine proprietary 'zero following error' axis control algorithms. Hardware is designed in Germany while software is written in the United States, giving the firm end-to-end control over its technology stack.

The core product portfolio is anchored by the PMC 9 open CNC platform for new machines, retrofits, and custom applications; servo amplifiers (SD2B plus, SD3, SD2S); multilevel frequency converters (SD2M, SD4S, SD4M); vector-controlled spindle drives (FC71); and the MC2 motion controller. Differentiated technical specifications include spindle speeds up to 480,000 rpm, 0.007° positioning accuracy, three-level converter topologies up to 450 kVA with liquid cooling, and Industry 4.0 interfaces including OPC-UA, PROFINET, EtherCAT, and CANopen. SIEB & MEYER USA also provides drivemaster2/3 and fcontrol 8x software tools, in-house repair services, TeamViewer-based remote support, and machine retrofit services for legacy brands including Gildemeister, Cincinnati, Warner & Swasey, and NASA.

Revenue is generated primarily through enterprise field sales of hardware (CNC controls, servo amplifiers, frequency converters) to OEM manufacturers, retrofit customers, and custom application builders in the US and Canada, with a channel partnership with SPINDEL Electronics for high-speed frequency converters and group-level distribution via the parent. Over 50% of drive technology sales originate from customized projects, and service revenue is generated through in-house repairs and hourly technical support. Key end markets include automotive, aerospace, PCB manufacturing, semiconductor, industrial automation, and precision machining. The company is part of the First Tool Group family of precision manufacturers in Dayton, Ohio, and a strategic partnership with SKF was announced in September 2025 to develop integrated inverter and magnetic bearing solutions.
