Mechanical Structure(CNC Wire EDM VG400)
Designed based on Japanese high-precision mechanical structure principles, the machine body is optimized using Finite Element Analysis (FEA). An optimized rib (RIB) structure effectively supports the column, minimizes casting stress deformation, and ensures a solid foundation for high-precision machining.
The machine base adopts a high-rigidity honeycomb casting structure, combined with an enlarged base span design to significantly enhance overall rigidity and mechanical accuracy.
The water-cooled lower arm design effectively prevents thermal expansion caused by discharge heat, further improving cutting accuracy and long-term stability.
Equipped with a stainless steel worktable with hardness up to HRC50, offering excellent wear resistance and durability for long-term operation.
High-response AC servo motor system ensures precise positioning and stable cutting performance.
Rigidly designed U/V axis casting structure provides stable and accurate taper cutting capability.
CNC Control System(CNC Wire EDM VG400)
Powered by Windows XP Embedded (XP-e) industrial control system, featuring a user-friendly graphical interface, stable performance, and excellent expandability for CAD/CAM and 3D display applications.
Supports touchscreen, mouse, and keypad operation, adapting to different operator preferences.
Equipped with an Intel Celeron industrial-grade CPU, offering fast processing speed and high stability. Multi-task processing allows program simulation during machining without interrupting cutting operations.
The control architecture aligns with major global EDM brands such as Sodick and Mitsubishi, ensuring international competitiveness.
High Compatibility NC Programming
Supports multiple program input methods, including LAN, USB flash drive, and RS232 communication.
Highly compatible with mainstream NC systems. With simple parameter settings, programs from different control systems (such as FANUC, Mitsubishi, Sodick, Toshiba, etc.) can be directly read and executed.
Equipped with 512 MB SDRAM, enabling fast and accurate simulation of large NC programs exceeding 32,767 lines, ensuring smooth and efficient machining.
Discharge Pulse Control System(CNC Wire EDM VG400)
Utilizes high-frequency synchronized layout technology, ensuring each MOSFET ON/OFF timing error is controlled within 10 μs.
Advanced discharge feedback control classifies machining conditions into Normal, Arc, Inactive, and Short modes, allowing real-time monitoring of abnormal discharge waveforms.
Effectively prevents wire breakage caused by abnormal thermal concentration, while increasing effective discharge output, resulting in over 15% improvement in machining efficiency.
Real-time discharge status feedback to the controller ensures stable servo control and significantly reduces wire breakage.
AC Non-Electrolytic Power Supply (Machining Efficiency)
Newly developed full-time AC non-electrolytic cutting power circuit improves machining speed by 10–15% compared with traditional DC power systems.
The AC non-electrolytic power supply significantly extends mold service life, achieving 5–6 times longer life than conventional DC systems.
Combined with an intelligent ignition circuit that automatically optimizes cutting signals, maximum machining speed reaches up to 180 mm²/min.
Intelligent OV Circuit
Dedicated intelligent ignition control circuit automatically adjusts ignition voltage according to different materials and workpiece thicknesses.
Built-in voltage stabilization control maintains a consistently high-speed and stable discharge state.
Especially effective for thin and thick workpieces, improving machining efficiency by up to 20%.
Intelligent Corner Control
Advanced corner control technology ensures precise fitting between punch and die while maintaining the required clearance.
Intelligent parameter adjustment based on wire diameter, workpiece thickness, cutting angle, and corner radius.
Significantly enhances corner accuracy and overall contour quality, especially for complex geometries.
Automatic Wire Threading System (Optional)
Highly reliable automatic wire threading system enables 24/7 unattended operation.
Exceptional ability to rethread directly from the wire break point, without returning to the start point or draining water, greatly reducing downtime.
Supports underwater rethreading at the break point, delivering an extremely low threading failure rate.
Wire straightening design accommodates various wire brands without adjustment.
Integrated wire annealing and straightening functions achieve a threading success rate close to 100%, even at Z-axis heights up to 300 mm.
