Design and Fabrication of Rotary Axis for WEDM (Wire electrical discharge grinding)

The paper gives an overview of designing of rotary axis for WEDM and fabrication of the same. WEDG the combination of WEDM with grinding a Hybrid Machining Process, WEDM has lot of advantages so all the Hybrid Machine are use the help of WEDM but here WEDG is used to produce the micro components like probe and micro electrodes. One such combination is wire electrical discharge grinding (WEDG), which is commonly used for micro-machining of fine and hard rods. Here the workpiece need the tendency to rotate where the wire is pass through based on spark erosion principle the rod can be grinded to our required small and precise diameters like 0.4mm, the existing WEDM can only used to produce through holes with the help of this we can able to reduce the components diameters and lengths WEDG also has an ability to produce micro components with high aspect ratios the rotation of workpiece is taken cared of with the help of spindle that coupled with AC motor
