Thread: Chinese 3040T Arrives
Nice pickups Gregor! Have you got a CNC coil winder too?
I used my cnc router & 3 hall sensors to scan a pickup's magnetic field. The one and only benefit of having a rubbish MDF machine is that it does not distort the magnetic field!

No I don't use the cnc to wind pickups I have made a pickup winder so I can scatter wind them it takes about 6mins to wind them at about 1200 rpm
my spindle on my machine only goes up to 8000, the cut depth is 0.8mm and it cuts the phenolic board pretty good, I did cut some plastic with it and it melted the plastic but I found if a used a little bit of wd40 it was fine I haven't used it on delrin. The end mill I mostly use is 1.5mm but have used 3mm for removing material. I am sure other members will give you better advice on what to try as I am really only a beginner.
If you use the correct type of cutter with a decent spindle and 10-12mm cutter then there's no reason why you shouldn't rough out 16mm nylon in 3 passes. One problem with nylon is that it can wrap around the tool so having air blowing helps clear this and also gives a slightly better finish. Taking deeper cuts makes bigger chips and this also helps but means going slower so soem experimenting is needed to find best balance.
