LPKF ProtoMat 93s Manual

7.7 Milling wide isolation channels

Wide isolation channels can be made with a 30 mm long contour milling cutter.
Various diameters are available.

The milling depth must be set such that when the copper is removed, only minimal
burring results. The 3 mm contour milling cutter is particularly well suited for milling
very wide isolation channels (VDE regulations).

7.8 Front plate engraving

For engraving, set the speed of movement as appropriate for the engraving depth
and the material. Use an LPKF universal milling cutter or LPKF double chamfered
cutter.

Attention! Use extractor when engraving, too!

Aluminum front panels can be milled through with the LPKF ProtoMat 93s circuit
board plotter.
