NC Servo Technology

What NC Servo Technology does

NC Servo Technology is an independent, third-party repair facility founded in 1975 and headquartered in Westland, Michigan, specializing in component-level repair, rebuild, and testing of servo valves, proportional valves, servo drives, and electronic control systems. The company operates 13 dedicated hydraulic test stands, including a Hagenbuch Proportional Test Stand, and maintains an inventory of more than 19,000 valves and electronic controls, much of which consists of discontinued or obsolete parts that OEMs no longer support. Its technical capabilities include pilot stage cleaning, spool service, coil rebuild, feedback verification, capacitor and IGBT replacement, circuit board repair, and handling of digital servo valves with CANbus, PROFIBUS, and EtherCAT protocols including program extraction and restoration.

The company's customer base spans Aerospace, Construction, Military/Defense, Heavy Industrial, Injection Molding, and General Manufacturing segments, serving customers across the United States with both standard and 24-hour rush turnaround options. Revenue is generated through professional services (repair labor), rebuilt/exchange unit sales, and aftermarket parts sales, all priced via quote-based transactions initiated through phone (734-326-6666) or website contact forms. NC Servo explicitly positions itself as OEM-independent, providing objective repair recommendations, and offers a 1-year warranty on parts and workmanship. The firm is privately held and founder/owner-operated (Eddie Harmon), with 11-50 employees, no external funding rounds, and a single operating location. Its proprietary product, the NCSA-110-300 servo valve, represents a modest extension into in-house manufacturing beyond pure repair services.
