Fast EDM 

Fast EDM (High-Speed Electrical Discharge Machining) is an advanced technology evolving from traditional EDM. By optimizing pulse power supplies, discharge parameters, and servo control systems, it enhances machining efficiency and precision. Current technical branches primarily include:

Fast Hole Drilling EDM

Features: Utilizes rotating tubular electrodes to achieve high-speed machining of micro-holes (starting from 0.1mm diameter), with hole diameter accuracy reaching ±0.005mm and surface roughness Ra ≤ 0.8μm.
Advantages: Processing speed is 3-5 times faster than conventional methods, suitable for micro-hole machining with aspect ratios >10:1, such as cooling holes in aero-engine blades and fuel nozzles.

High-Speed Die-Sinking EDM

Features: Utilizes multi-axis motion control and adaptive discharge technology to achieve high-speed precision finishing of complex cavities, boosting processing efficiency by over 40%.
Applications: Final forming of high-value-added components such as automotive molds, precision connectors, and medical devices.

Hybrid EDM

Features: Combines EDM with ultrasonic vibration and high-pressure jet technologies to reduce heat-affected zone thickness (≤5μm) and enhance surface integrity.
Applications: Precision machining of difficult-to-process materials like titanium alloys and high-temperature alloys, such as artificial joints and turbine discs.
