Wire EDM (Electrical Discharge Machining) is an exceptional process that uses electric current and fine wire to cut and shape metals, metal alloys and other conductive materials. It leaves a smooth surface that usually requires no further finishing or polishing.
Fine, High Aspect Ratio Features
Precision Micro's high precision CNC driven Wire EDM facility is capable of producing precision, high aspect ratio apertures and features with tolerances of <± 5µm that could not be achieved using other metal cutting techniques. Surface finish down to Ra 0.1µm can be achieved, which in many instances eliminates the need for subsequent polishing.
Versatile Yet Precise
The process is highly accurate and repeatable. It produces exceptionally precise, parallel sidewalls, allowing stacking when machining multiple parts from sheet material. Taper cuts, free curves and complex shapes can be achieved simply by rotating the axis of the wire before or during the process.
Wire EDM features can be incorporated in components manufactured by etching or electroforming, producing high aspect ration features beyond the capabilities of those technologies. . The software is common to our milling and turning operations, enabling work pieces to be easily transferred between machines for multi-cavity work and high precision finishing.
Precision Micro's Wire EDM is digitally driven, virtually eliminating the need for fixtures and tooling for one of a kind or low run production run parts. Further finishing is generally unnecessary and parts may be used immediately in assembly, minimising the time between design and delivery.
To further increase the productivity of an already very efficient machine, Precision Micro has also invested in a low profile, universal, work holding tooling system,” said Mick Taylor, Market Development Manager. “By presetting the work piece away from the machine we are able to minimise machine set-up times, improve flexibility and increase our machine utilisation; all of which helps us to be more competitive in the market.”
