The secret to the ultra-high speed of wire EDM machines lies in their 'heart'-the high-frequency pulse power supply. Traditional machining discharges approximately 50,000 times per second, while ultra-high-speed models can reach over 200,000 times per second, like upgrading from a single-shot rifle to a machine gun. This microsecond-level discharge generates temperatures of tens of thousands of degrees Celsius, instantly vaporizing metal without damaging the workpiece. Combined with a 0.02mm fine molybdenum wire, the cut is thinner than a human hair.
The Precise Dance of the Intelligent System
Dynamic Tracking: Real-time monitoring of the discharge gap automatically adjusts the wire feed speed.
Path Optimization: Calculates the shortest cutting path like GPS navigation, reducing wasted tool travel.
Error Compensation: Automatically corrects thermal deformation errors using temperature sensors, with an accuracy of ±0.005mm.
Innovative Breakthrough in Cooling Technology
The heat generated by ultra-high-speed machining is equivalent to three times that of electric welding, making a new composite cooling system crucial. Utilizing atomized coolant that penetrates the cutting zone, combined with a multi-directional jet design, cooling efficiency is improved by 70%. Some models also incorporate liquid nitrogen-assisted cooling, enabling processing speeds to exceed 500 mm²/min while maintaining a surface roughness ≤ Ra0.8 μm.
