Wire cut machine – 6 basics you need to know before buying one

Machine, Die Cast Tool, Tooling Industry

1) Benefits of using a wire cut machine: - Workpiece thickness - Cutting hard materials - High accuracy - Superior surface finish - Not heat distortion - Burr-free cutting 2) How does a wire cut machine work? Wire EDM works by creating an electrical charge between a wire electrode and a workpiece. Therefore, when the spark jumps across the gap, it removes metal from the workpiece and the wire. 3) Components in a wire cut machine - CNC unit - Power supply with anti-electrolysis circuitry - A mechanism for automatic wire threading - Tank to contain the dielectric fluid - Chiller to keep the dielectric at a steady temperature - Filtration system for dielectric fluid 4)How does a wire cut machine cut? The wire cut machine works by sending a current between the wire and the workpiece, causing millions of sparks to fly. Therefore, this sparking generates heat, about 15,000 degrees Fahrenheit—enough to melt away microscopic bits of the workpiece, creating fine cuts and intricate shapes. 5) Why submerged wire-cutting? - Submerged cutting - Splash flushing 6) How many axes does a wire cut machine have? As you may know, a CNC unit moves the machine in an X-Y plane. It can position the upper guide independently in the U-V axis. Hence, simultaneous repositioning all four axes (X, Y, U, V) allows the wire cut machine to cut tapers or shapes that transition from top to bottom. A programmable Z-axis enables workpieces with different thicknesses to be machined automatically.
