- CNC die-sinking EDM designed for medium-size mold and production applications, with 400 × 300 mm X/Y travel and 350 mm Z travel.
- High-rigidity mechanical frame optimized using FEM analysis, with a column-type structure and floor-mounted design for stable precision machining.
- Uses roller-type linear guideways, which Excetek specifies as having approximately 1.7 times the rigidity of ball-type guides.
- High-resolution AC servo system and absolute-coordinate feedback improve positioning accuracy, machining stability and position-memory reliability.
- Hardened worktable with approximately HRC 50 surface hardness.
- MOSFET discharge circuitry is designed for high erosion speed, reduced electrode wear and smooth surface finishing.
- Generator includes ARC and short-circuit protection, automatic machining-condition control and dedicated discharge functions for copper, graphite and tungsten-carbide applications.
- Fuzzy intelligent control monitors discharge conditions in real time and automatically adjusts output to improve stability, machining efficiency and electrode life.
- Excetek’s ES mirror-finishing discharge technology can achieve surface finishes down to approximately Ra 0.1 μm under the manufacturer’s specified test conditions.
- Controller supports automatic machining-condition selection, ISO G-code programming, machining simulation, multiple measurement functions and 18 OB orbiting modes.
- Optional automation includes 4- or 6-position ATC systems and 16- or 20-position Robomatic electrode changers, with automatic electrode offset and C-axis compensation functions.
- Standard equipment includes alcohol fire extinguisher, working lamp, leveling pads, flushing unit, paper filter, 1/2″ drill chuck, toolbox and clamping jig.
- Optional equipment includes C-axis, automatic tool changer, X/Y/Z linear scales, edge-finder ball, oil chiller, automatic voltage regulator, permanent magnetic pedestal and tungsten-carbide sparking circuit.
The ED400C provides 400 × 300 mm X/Y travel and 350 mm Z travel. The worktable measures 700 × 400 mm, and the maximum workpiece size is 850 × 580 mm. Maximum workpiece weight is 1000 kg, while maximum electrode weight is 50 kg. The electrode-head-to-worktable distance ranges from 300 to 650 mm.
Machine dimensions, including the machine body, travel envelope, tank and generator, are 2344 × 2110 × 2410 mm, with a machine weight of approximately 2800 kg. The oil-filter tank has a capacity of 450 L and uses three paper filters.
