Wire cutting


Use of wire of Ø0.07, Ø0.05, Ø0.03, Ø0.02 (20 μm). Some components weigh less than 0.001 gr.

High precision

Ra 0.15 mini and Ra 0.02 after polishing (plan overthickness of 2.5 μm). Day-to-day production of control gauge at ±0.003. Hole calibration at ± 0.002.

Single part

Most of machined parts are customer parts that have already been finely worked, so we are not allowed to make a mistake!

Production run

Some series require the use of wire cutting machines 24 hours a day for 4 months.
