3D surface milling with Low Power CNC machine

[Irankis]

Hi guys!!!

I'am sorry if I posting my question in incorrect thread, but I have 1 question about 3D surface milling. It's possible to mill nice surface with Low power CNC machine (in this case HAAS VF2 - VF4 CNC VMC)? I'd like to Mill Brass with Sphere or Ball End mill but my CNC machine has max 7000-7500 rev. Sorry for my bad english.

Any useful help?

I wouldn't think you would have any problems. I recently 3d machined a small picture frame using a 3/32 ball end at 5000rpm on a very small X2 type mill. It was roughed out of course first, but the intricate profiling was all done with the ball end.

Thank you for your kind reply! Ill try it!

Plenty of YouTube videos showing this being done:

You should be able to get a nice finish with that. A few things come to mind , is your cutter new ? How fast is the feed rate ? Did you try a bit of coolant or some other lube on the part ?

If you are using a ball nose end mill 7000 rpm will be fine just use .005 step over... nice finish.
