Ultra Precision 2 Axis Wire EDM Machine ARTA 122 NANO

    Designed specifically for solving problems of high-precision processing standard (diameter 0.1-0.3 mm), and a special thin wires (diameter of from 0.01 mm = 10 µm). Provides the minimum width of the cut groove is less industry is 20 µm. Is used in the production of micropetala microwave equipment, items, devices, nanotechnology products increased accuracy.

    Discrete positioning (as specified in the control program): 100 nanometers (100 nm = 0,1 µm)
    Resolution interpolation (step movements): 10 nanometers (10 nm = 0,01 µm) !

    Technical features:

  • X, Y axes: Linear Guideways, Ballscrew Ultra Precision Class (THK, Japan)

  • The feedback system (axes X,Y) on the basis of high-speed optical linear encoders with an accuracy of position of 0.1 μm (Renishaw)

  • Generator with microprocessor control and tracking of single pulses (provides a current pulse duration of 0.1 μs and a frequency up to 200 kHz)

  • Winding / Tension Wire Mechanism with the use of ultra-precise marker of waste wire and special brake clutch

  • Refrigerator thermostat (Cooler) to automatically maintain the desired temperature of the working fluid
