Sinker EDMs for large workpieces

The EDNC10, EDNC15, and EDNC20 sinker EDM machines accommodate large, heavy workpieces while producing delicate, fine features with high accuracy and excellent surface finish.

The machines feature 60A (80A peak) power supplies, with 120A or 240A optional. The EDNC10 and EDNC15 machines use three-sided programmable drop tanks, providing ergonomic access for setup and operation. The EDNC20 features a programmable rise and fall front door that controls dielectric fluid level and can be set to match the height of the workpiece while providing optimum viewing of the machining operation.

HyperCut technology increases power levels without additional reduction on the electrode, improving roughing speeds by up to 30%, minimizing electrode wear while providing fast machining speed.

SuperSpark IV adaptive control technology optimizes machining discharge power and electrode jump motions during roughing and finishing operations. This technology is effective on rib or drafted electrodes, and when combined with HyperCut settings, can reduce total machining time by up to 50%.

All EDNC-series sinker EDMs can be equipped with high-quality surface finish (HQSF) technology that yields 50% better surface finishes than conventional systems. HQSF technology can extend tool life through improved surface integrity and reduce cycle time when fine surface finishes are not required.

The HS-Rib Z-axis configuration option reduces rough machining speeds of small electrodes and provides enhanced jump speeds of up to 20m/min that can reduce machining times by up to 60%.

EDNC-series machines are equipped with Hyper-i control systems that improve productivity by simplifying the machine interface. A 24" high-definition touch-screen monitor allows users to select machining conditions for workpiece and electrode material type, the desired feature shape, and surface finish. Hyper-i control integrates on-board digital manuals, intelligent E-Tech Doctor help functions, and an e-Learning training system.
