What you should know
Operating Manual 7.1 Rev.: 18.06.2008 31
When using the conical tools Universal Cutter and Micro Cutter, you must
set the milling width to the desired size with the milling depth limiter.
Enlarge the milling depth for cutting wider milling tracks, reduce the mill-
ing depth for narrow milling tracks.
Always check the milling width at the lower edge of the (copper) laminate
to ensure the required electrical isolation between the conductor tracks.
Fig. 12: Milling width with Universal Cutter and Micro Cutter
1 Milling depth not sufficient,
no isolation
2 Milling depth too shal-
low,
milling track too narrow
3 Milling depth too deep,
milling track too wide
4 Milling depth perfect,
milling width equal to nominal
width
a - Nominal width, B - Milling width, c - Conical tool (Universal Cutter, Micro Cutter), d - (Cu) laminate, e - Carrier material

Tip: Use the LPKF measuring microscope to check the milling width
exactly.
