Cheers Balsaman, yep, wooden machine so I'll give the WD40 a go. Maybe it's the cutter, it's a 4 flute so I guess it will always plug up quickly. As for the Ali, it has numbers on it, but they are way blurry! It's 60xx, and it's quite a hard alloy. It's been around the shed for a while, i cut it with a hand router a year ago using a 4mm aluminium spiral cutter in one pass with no problems. I guess I just gotta get used to the CNC methods! The feedrate is giving me difficulty at the mo, using Ace converter, it does not add the figures, so manual editing is necessary, then, using Turbocnc as a controller, the "feedrate override" does not seem to have any effect. I just want to get it right first time, going slow is ok, and then I can work it up from there. 0.2" = 5mm, so I should be ok cutting in one pass. |
