For Sale! Roland PNC 3000 milling machine

[fidia]

Hi Robin

Glad the machine arrived OK. It was well packed alright but better to go with the overkill. It is a nice machine, pretty sturdy. I would have liked to change some of the components but just was busy running parts so never had the time. The yahoo group has alot of info and people who have added components and made fixtures.

I ran a 6mm bit on aluminum on a few programmes with the air cooling and it didn't have a problem as long as they are small cuts. It would be better with a timing belt and a flood coolant system but I used the air as I never thought I would get to fitting one.

Hi Brian

Your problem was in the motor speed control, the poor thing is stuck on top whack

I clocked it with the jolly old digi-tacho and it is doing 10,600 rpm. Air cooling? Liquid nitrogen might have been a better bet :rofl:

I cleaned the shaft encoder and the rpm display burst in to life. Still can't slow t'bugger down though because the speed control pot is worn out. Can't be bothered to replace it because I'm planning on reworking the speed control anyway.

Not complaining, I do this for fun. Best of all, it has passed wifely inspection as white goods and been approved for desk top use in the warm. My cup runneth over

best

Robin
