Brass wires are generally used for metal works. Brass wires are made by copper/zinc ratio of 65/35 or 60/40 depending on the machine type or manufacturer. Zinc-coated wires are used for high speed machining (also known as coating wire) and piano wires (brass / zinc coated) , tungsten wires are used for precision machining. Please refer to our catalog and web site for more information.

Wire Electrodes

After cleaning and wiping the guide area on the machine with degreasing agents (V-Clean Spray), align the screws vertically before setting the wire guide. If the screws are not in vertical positions and is forcibly installed may cause machining defects or damages.

Our pipe electrodes are applicable for small hole EDM. Available sizes are from OD 0.08mm to OD 6.0. Please contact your nearest Sodick for other sizes.

Pipe electrodes are made of copper and brass and are highly conductive. Discharge creates a discharge gap between the electrode diameter and the work piece, so the actual hole diameter is larger than the electrode diameter. It is supposedly to expand approximately D0.1-D0.3mm. (E.g. D0.8 mm pipe electrode will generally open a hole of approx. D1.0 mm.) The larger the pipe diameter, the larger the discharge gap will occur which will create a larger hole.
