Considering DIY machine build - reality check

[greenz123]

Yes by widths I mean Id like to be able to cut very small details, some as small as 0.1mm.
Im not even sure a 0.1mm bit would do anything other than drill 0.1mm holes though ? I imagine the bit wouldnt have the strength to travel through any material laterally ? The design I have in mind has thousands of holes ranging in size from 3mm to 0.1mm. Is this feasible ? Am I expecting too much ? As I said Id like to be able to drill/cut multiple sheets at a time too.

Thats just tooling accurecy not positional accurecy. Cutting with 0.1mm tool is easily done with correct tooling and feeds etc.! . . . . . What resolution would you like to work to IE: Smallest movable amount.?

0.1mm is not considered high positional accurecy for CNC work so if your talking this is highest positional resolution you'd like to work with then yes can be achieved and not too much to ask for DIY.
