Tolerances and limits

EDM machines:

Wire erosion:          Ø 0,03 mm ~ 15 mm depth

                                  Ra 0,05 µm (N2)

Die-Sink Erosion:    Ø 0,03 mm ~ 0,2 mm depth

     Ra 0,1 µm (N3)

     M2 x 10 mm

Micro drilling:           Ø 0,1 mm ~ 3 mm depth


HSC Milling:

Micro milling:      Ø 0,1 mm x 0,5 mm depth

Ra 0,05 µm (N2)

Milling with monocrystalline diamond:           Ra 0,025 µm (N1)

Carbide milling:             Ø 0,2 mm

Carbide driling:             Ø 0,4 mm x 4 mm depth

Carbide thread:            M2x4 mm


Polishing / Finishing:

Ra 0,01 µm (<N1) superfinishing


Restrictive tolerances are usually considered as ± 2 µm.
