Multi-electrode replacement machining method
This method uses multiple electrodes that are replaced sequentially to machine the same cavity. It offers high profiling accuracy and is particularly suitable for machining cavities with sharp corners and narrow slits.
However, its disadvantages include the need to manufacture multiple electrodes using precision machine tools, the requirement for high repeatability during electrode replacement, and the need for accessories and fixtures.
Segmented Electrode Machining Method
This method combines single-electrode translational machining and multi-electrode replacement machining. It offers high process flexibility and high contouring accuracy, making it suitable for machining complex cavity molds with sharp corners, narrow slots, countersunk holes, and deep grooves. Based on the cavity geometry, the electrode is decomposed into main cavity electrodes and secondary cavity electrodes for separate manufacturing. First, the main cavity is machined using the main cavity electrode, and then the secondary cavity electrodes are used to machine areas such as included angles, narrow grooves, and irregularly shaped blind holes.
EDM swing machining method
During processing, the electrodes are continuously oscillated to ensure consistent discharge gaps at high efficiency and maintain high machinability. This method yields more uniform surface roughness on both the sides and bottom, and makes it easier to control machining dimensions.
Multi-Axis Linked Machining Method
Multi-axis linkage enables the machining of complex cavity molds or tiny parts that are difficult to process with traditional EDM machines, such as three-dimensional helical surfaces, micro gears, and micro racks.
