IH mill .160" thou 100 IPM.MP4

IH Industrial Hobbies, Zay-7045, RF-45 type mill with upgraded 4HP 3600 RPM motor cutting 6061 at 100 IPM .250 DOC at 3700 RPM with a 2.5 inch face mill.

I did a few test cuts to see how the new motor cuts. It looks like I still have lots of power left and the mill is handling it well.

It is a Grizzly G2861 Fly Cutter which is a better tool than much of the Ebay stuff. After you upgrade the inserts it is a fine cutter and the hard coating is tough and easy to clean up. I thought I paid less so it might have been on sale two years ago.

One of the guys at CNC Zone said a ,25 cut would be 2.8HP so that should be OK but the face mill has no spec as to max DOC.

I also have a Glacern FM-45 that they said could cut over .25 per pass so I think both of the tools may be OK for deeper cuts. I just don't want to bang up the 45.

I may do a thin pass at .25 to see how it goes but I'm doing other work in the shop right now and making a video means leaving the chip curtain open and the whole shop fills up with chips.

I re checked the Z to see if it was set correctly and it is fine but I did find the mistake.

After each pass I was re zeroing the Z and doing the next pass. But the head was not at zero but at the clearance plane which was .070"

So the correct DOC was .160"

I will correct the title.

I might re do the test at .250" to see how it goes if people want to see it.

Should I go for it?

I picked up my machine off craigslist. A ZX45, the guy that had it before me must have been cutting nothing but aluminum, the oil was baked onto the gears. And this is still a 1700 rpm motor. I keep dreaming about a 4hp 3600 rpm but the gears and heat have me worried. I figure I can run the oil through an inter-cooler and back into the head if I need to. I don't know If I'm ready to get fancy with a belt just yet.

Well that just lowered my mini-mills self esteem another couple points lol. That is an awesome machine. Great work on the CNC conversion and motor upgrade!

That is craziness. What brand of facemill is that?

Please, by all means do it - and get it on video! I don't think that @ 100IPM that thing will make it, that's pretty fast for a 4HP machine and a relatively small frame. (I have one just like it, but not CNC'd - yet)

Not sure where you're measuring - but that's not a .250 DOC. Looks more like .050. Even with 4HP that motor would bog down quite a bit with .250 DOC and 100IPM!
