We're looking at a VF2 and had a few questions Haas head quarters couldn't answer. Our current machine isn't producing the finish we're after and think it boils down to a number of things. So we're looking to level up. Before you look at the pictures of our current finish, I'll add our machine is limit to 1.5HP, stepper driven, dovetail ways, 5140 top RPM. The speeds, feeds, WOC, DOC below are best results we saw after many test (your opinion is welcome). The part is 6061-T6 AL spiral rough and finished with a ZRN coated .5" 2 FL 37° helix SQ EM. Leaving .02" for the finishing cut ran at
2500 RPM
25 IPM
.4" DOC
.02 WOC"
Flood coolant
Climb cut
Few more random parts
carbide .5" 3 FL at
2500 RPM
25 IPM
.6" DOC
.01 WOC"
Flood coolant
Climb cut
If any of you that own a Super Mini or VF2 and have a few high quality pics to compare that would be awesome !
If we throw the parts off the table into the tumblers, the finish it produces after being anodized is a muddy cloudy black. The tumblers have a flow through system and change the water/soap mix every 12 hours. We tumbler the parts for deburring only and belt/hand sand (along with a bunch of other stuff) to get the finish you see below. We've talked with other part makers in the industry telling them our process and were blown away at the time it takes. With other VF2 owners they simply throw the parts off the table in the tumbler and the finish they're getting is very close to ours without any extra work. So my guess is the finish our machine is leaving us to start from.
