CNC Control Circuit Board – OKUMA 1006-1102
The 1006-1102 is an electronic CNC control board (“CNC Control Circuit Board”) manufactured by OKUMA, the Japanese builder of machine tools and proprietary CNC systems. The part number falls within the standard electronic spare-parts nomenclature of OKUMA’s OSP (Open System Platform) control series, fitted on machining centres, CNC lathes, and turn-mill centres. The board handles processing, signal acquisition, or internal interface functions within the machine’s electrical cabinet. No specific revisions or included accessories have been documented beyond the board itself.
The electronic boards of the OSP series form the logical core of the OKUMA CNC system: each board is responsible for a specific function — axis processing, I/O, communication, or power — and failure of even a single board can render the machine completely inoperable. Timely replacement is critical to minimising downtime, as lead times for genuine OKUMA spare parts can be lengthy and costs high.
OKUMA Corporation is a Japanese manufacturer founded in 1898 in Nagoya, specialising in CNC machine tools and their own proprietary OSP control systems. Unlike many competitors, OKUMA designs and manufactures both machines and controls in-house, ensuring exclusive hardware/software integration. Electronic components from the older OSP series (OSP 5000, OSP 7000) are legacy / discontinued and available almost exclusively on the used market or through specialist repair services.
