Slow-wire Cutting Processing

Slow-wire Cutting Processing, also known as slow wire electrical discharge machining (SWEDM), is a precise machining technique used to cut intricate shapes and contours in conductive materials.     The process involves using a thin, metallic wire that is continuously fed through a workpiece while an electrical discharge is passed between the wire and the workpiece.     This electrical discharge erodes the material, allowing for accurate and precise cutting.

Unlike traditional machining methods, slow Wire cutting processing does not involve direct contact between the cutting tool and the workpiece.     Instead, a small gap is maintained between the wire and the workpiece, typically filled with a dielectric fluid that acts as a coolant and electrically insulating medium.

The wire used in Slow-Wire Cutting Processing is typically made of brass or other conductive materials.     The wire is continuously fed through the workpiece in a controlled manner, guided by computer numerical control (CNC) systems.     As the wire passes through the workpiece, an electrical discharge is generated between the wire and the workpiece, creating small craters in the material.


Slow-wire cutting processing offers several advantages over traditional machining methods.     It allows for precision cutting of complex shapes and contours, even in hard and brittle materials.     The process is capable of achieving high cutting speeds and does not create thermal distortion or burrs on the workpiece.     Furthermore, slow-wire cutting processing is a non-contact method, which reduces tool wear and prolongs the lifespan of the wire.
