- High-precision submerged wire-cut EDM with 400 × 300 mm X/Y travel, 120 × 120 mm U/V travel and 260 mm Z travel.
- X/Y axes use a linear motor drive system, while the U/V and Z axes are driven by AC servo motors.
- A 0.1 μm high-resolution linear measuring system supports precision machining and ultra-fine finishing.
- Rigid machine construction includes an FEA-optimized casting, extra-wide machine base and rigid U/V truss structure.
- Hardened four-sided stainless-steel worktable with hardness of approximately HRC 50.
- Machining technologies include Smart Corner Control, Stable Discharge Processing and Super Finish Circuit (SFC) for improved precision, together with DPM, Precision Mark Control and an Electrolysis-Free generator system.
- Integrated intelligent functions include remote monitoring, controller connectivity and portable-device monitoring.
- Supports high-speed Automatic Wire Threading (AWT), robotic workpiece transfer and probe-based automatic measurement and correction.
- The AWT system is designed for continuous unattended operation and can restart threading at a wire break point. For a 100 mm-thick workpiece, wire annealing/cutting and threading are each specified at approximately 10 seconds. Water-jet threading supports workpieces up to 500 mm thick.
- Graphical HMI provides workpiece positioning, maintenance and diagnostic information, machining-data search and other operator-assistance functions.
- Optional online measurement functions allow automatic reference-point calibration, workpiece alignment, post-machining inspection and automated multi-workpiece processing.
- Powered sliding-door design reduces installation-space requirements and improves access to the work area.
- Standard equipment includes X/Y-axis linear scales, Automatic Wire Threading (AWT), one spool of brass wire, clamping-tool set, 10 L ion-exchange resin, vertical alignment jig, two paper filters, two diamond guides, upper/lower flushing nozzles and two energizing plates.
Optional equipment includes clamping beam, W-axis, 15 kVA AVR, Jumbo Feeder L-50A, 15 kVA transformer, automatic front door, SMS function, signal tower, remote monitoring system, automatic measurement system and Super Finish Circuit.
The NP400L Plus is a submerged-type high-precision wire-cut EDM designed for workpieces up to 750 × 550 × 215 mm, with a maximum workpiece weight of 500 kg. Supported wire diameter is 0.15–0.30 mm. X/Y-axis travel is 400 × 300 mm, U/V-axis travel is 120 × 120 mm, and Z-axis travel is 260 mm.
The machine provides a maximum taper angle of ±30° per 100 mm when equipped with the wide diamond guide and nozzle. X/Y axes use linear motors, while the U/V and Z axes use AC servo motors.
Overall machine dimensions are 2260 × 2525 × 2150 mm, with a machine weight of approximately 3050 kg. The dielectric tank has a capacity of 650 L and is equipped with automatic deionization, two paper filters and an automatic chiller unit.
