GF Machining Solutions CT8121180B Printed Circuit Board

Charmilles CT8121180B is a printed circuit board (PCB) assembly used in Charmilles RoboFil and RoboForm CNC EDM systems, part of GF Machining Solutions’ legacy control electronics. Catalog entries identify CT8121180B as a circuit board with a dual-connector, rack-mount form factor, aligning with the style of control modules mounted in older Charmilles equipment. The part is associated with Robofil/RoboForm machines and is described in distributor listings as a repair or spare-part item, with multiple references to the CT8121180B alongside related CT8121xx boards. Some listings note that this family of parts has been discontinued by the manufacturer, which is common for legacy Charmilles components. As a core control-board component, CT8121180B facilitates interconnection among subsystems within the machine’s control network, carrying signals between the controller and peripheral interfaces that govern EDM operations. When sourcing CT8121180B, buyers should verify exact connector counts and mounting spacing against the machine’s service documentation and wiring diagrams to ensure compatibility, and consider refurbished or supplier-approved units given the part’s age. This PCB thus represents a specific, still-relevant maintenance item for Charmilles Robofil and RoboForm systems, reflecting the broader CT8121xx family used in Charmilles’ CNC EDM control electronics.
