Sinker EDM

CNC EDM Die Sinker Machines

High-accuracy EDM die sinking systems engineered for complex cavity machining, intelligent process control, and production-level throughput.

Absolute Machine Tools offers a complete range of CNC EDM die sinkers designed for precision mold making, multi-cavity tooling, and advanced component manufacturing across aerospace, medical, and industrial applications. From multi-axis platforms to conversational CNC systems and twin-head configurations, these machines are built to match specific part geometries, machining strategies, and production requirements.

Across the lineup, a key advantage is the integration of modern CNC controls and real-time process intelligence, including APC adaptive spark control, advanced orbit strategies, and high-speed EtherCAT communication. These technologies allow operators to monitor spark conditions, automatically adjust machining parameters, and maintain stable burn performance — resulting in improved surface finish, faster cycle times, and consistent results across complex geometries. Absolute Machine Tools delivers these capabilities in a platform that provides exceptional value compared to traditional high-end EDM systems, without sacrificing accuracy, surface finish, or performance.

Benefits for Metal Cutting Manufacturers

Solutions from Absolute Machine Tools

EX Series CNC EDM Die Sinkers

The EX Series is designed for high-performance, multi-axis EDM machining, offering X, Y, Z, and C-axis capability for complex geometries and advanced applications. With features such as helical machining, XYZC interpolation, and high-speed orbit strategies, the EX platform excels in multi-cavity molds, aerospace components, and intricate tooling where accuracy and surface finish are critical. Intelligent tooling systems and advanced sparking technology support consistent results and lights-out operation.

NX Series CNC EDM Die Sinkers

The NX Series provides a modern CNC-controlled EDM platform for toolrooms and production environments, combining ease of use with advanced process control. Featuring conversational Project Program programming, APC adaptive spark control, and XY orbiting, the NX Series delivers stable, repeatable machining for injection molds, vent holes, and precision tooling. With automatic electrode changer (ATC) options and automation-ready features, NX machines support efficient semi-automated production.

Twin & Single-Head (EX 2H / NX 2H) EDM Die Sinkers

Twin-head EDM die sinkers are engineered for maximum throughput and large-format cavity machining, featuring dual independently controlled rams within a single dielectric tank. This configuration enables simultaneous machining of multiple cavities, synchronized burn cycles, or combined roughing and finishing operations. These machines are ideal for large molds, aerospace dies, and high-volume multi-cavity production where productivity per machine footprint is critical.
