I. High-Rigidity Machine Body & High-Precision Drive System
1. This ultra-high-speed wire cutting machine adopts a robust box-type bed made of premium HT250 resin-bonded cast iron. The bed undergoes secondary tempering and vibration aging treatment to completely eliminate internal structural stress, preventing permanent deformation during long-term continuous operation and sustaining consistent, ultra-stable machining accuracy throughout its service life.
2. The ultra-high-speed wire-cut EDM machine X and Y linear axes are fitted with Taiwan HIWIN precision linear guides and Nan Gongyi high-precision ball screws, matched with an AC servo closed-loop drive system. This integrated configuration delivers rapid response, superior positioning accuracy and ultra-smooth motion, mechanically underpinning the stability and precision of high-speed cutting while comprehensively optimizing overall machining efficiency.
3. The ultra-high-speed wire-cut EDM machine equipped with a large-diameter Φ260mm wire spool, the machine supports a maximum molybdenum wire loading length of 800mm. This design effectively reduces wire direction switching frequency, minimizes idle stroke energy waste, and extends effective cutting duration. Paired with a variable-frequency stepless speed regulation system, the equipment maintains stable and controllable operation across high and low speed ranges with precise speed calibration, greatly suppressing wire vibration and delivering flawless, burr-free cutting surfaces.
4. The ultra-high-speed wire-cut EDM machine adoption of a large-diameter Φ70mm guide wheel lowers the rotational speed of guide wheel bearings, effectively mitigating wire vibration and enhancing operational stability during high-speed cutting. Complemented by a customized constant-tension wire tensioning mechanism, the system sustains constant molybdenum wire tension throughout the entire machining process, eliminating wire vibration and slackness. This innovative structure completely resolves the problem of workpiece surface scoring in high-speed cutting scenarios, significantly reduces high-speed wire breakage rates and threading downtime, and effectively improves product yield and production capacity.
5. The ultra-high-speed wire-cut EDM machine’s working fluid system integrates a multi-stage precision filtration tank, which efficiently purifies working fluid and enhances residue removal performance. It ensures uniform and stable jet flow during machining, rapidly flushing away electro-corrosion byproducts and cutting heat in real time. Fully adaptive to ultra-high-speed cutting working conditions, the system provides reliable core support for efficient, stable and high-precision machining.
II. Ultra-High-Speed High-Frequency Discharge Power Supply & Intelligent Control System
1. The ultra-high-speed wire-cut EDM machine with a new-generation high-power high-frequency pulse power module, the machine adopts a premium bridge circuit architecture and high-performance signal processing chips to output precise, powerful and stable pulse signals. It achieves a maximum cutting speed of 400 mm²/min, delivering over 30% higher processing efficiency than traditional EDM wire cutting power supplies. While accelerating machining speed, it effectively reduces molybdenum wire consumption and overall power consumption, cutting long-term consumable and electricity operating costs.
2. The ultra-high-speed wire-cut EDM machine features an innovative direct connection design between the high-frequency power cable and guide wheel, eliminating the traditional conductive block structure. This design reduces current transmission loss, enables more accurate discharge tracking and more stable cutting operation, and completely avoids discharge anomalies and machining instability caused by conductive block wear. It significantly improves discharge energy utilization, further elevates cutting speed, and optimizes workpiece surface quality. The finished workpiece is free of streaks and ripples with superior surface finish, greatly upgrading overall product processing quality.
