Great video John. Thanks. We do a lot of High Feed Milling, but usually with face mills 1" dia - 4" dia, and usually only for roughing. We use Ingersoll Tools Gold Quad and Midi conservatively at .030" and .020" per tooth and the same .030" and .020" DOC. We are usually cutting FX-2 Die Steel at about 400 SFM. Our typical feeds are 100-120 IPM.
Thanks John, very informative...Time is money of course but that is a pretty hefty entry price for the cutter...I can envisage tears in the coolant tray when it breaks!
Love these tools especially the lakeshore carbide tool in this video! They really kick up the wow factor in a larger faster machine and start dancing around at 320 IPM.
Strategy to go for internal contours with a lot of shallow angled areas. Instead of a purpose-highfeed endmill you can improvise with a bullnose endmill. If even works with a standard carbide endmill that has a corner-chamfer.
In a job shop often you don't get the huge cubes of material you see in tool demos. You make more parts that are longer and wider than they are tall. So you can't always use the full flute of a tool anyway. Using a 1 inch, 2 inch or 3 inch feed mill becomes hard to beat in terms of material removal rate. Even taking a small width of cut, roughing the outside of the part is extremely effective, shorter flute = less chatter. Plus using small inserts with 3+ sides means you save a lot of money on carbide. I don't know how math works out for the solid carbide ones. At my last job we did a lot of stainless and these things cut part time down immensely.
A guy from Seco explained high feed milling to me in a way that made sense. His take was, essentially, that high feed end mills coupled with a high feed, low DOC strategy produces high axial force and low radial force on the end mill, tool holder, spindle, column, etc. This takes advantage of the highest plane of stiffness in the C shape of a mill, leading to a more stable cut and better all round results. In a pinch I've run a high feed strategy with a standard 4-flute Guhring carbide end mill in 316 stainless on a Tormach 1100 with decent results.
I used to work at a mold shop and we’d rough out entire cavities/cores with a high feed indexable cutter. Granted we used Makinos with high rpm spindles....
nice , i saw some Kennametal high feed mills on their youtube channel . They pushed it at something around 12000mm/min feed . in STEEL . The mind boogles .
This is where the high Rpms come into play on these new machines, like I said before, it would have been cool to go even faster then the 7000 or so rpms on the 770. I guess that is what the vf2SS is for
I was excited about this tool, I do a lot of slotting.. But looking at the feeds and speeds chart on the lakeshore website, i do not see aluminum on there... Not good for aluminum I guess?
Since you can effect avoid Chatter and the load on the guideways are consistently lower i would say that it is not so bad.If there is a better tool i will not use HFM.BUT in the last few years, i had to mill a few parts, where i was really happy to have access to this tools.
Hey nice video and really educative. I have suggestion regarding to use milimeter also at your video. Because asia and europe region we use milimeter. It would increase your audience no only for us audience. Hope it help
Hey John, great that you start using those small high feed tools. When you do machine deep slots and pockets, try to use some tools with inner coolant holes and air through the spindle. It works much better then external air! Greetings from Germany :) Nico
Just wondering whether a slotting saw would give you the slots in the piece you demoed more quickly and cheaply? For the rectangular pocket/any slot that's not straight through the part it's not an option of course, but depending on how often you need through slots vs. internal slots/pockets, I suspect the slotting saw option could give you more bang for your buck. Tormach have a few other uses for them too: www.tormach.com/blog/3-things-using-slitting-saw/
Thepriest39 Steel, iron, stainless, high nickel alloys, hardened materials, and more. Not a big reason to use them on non-ferrous materials, in my opinion.
The 210's are a rough feed mill. I moved away from them and back to the Iscar wmot insert and the newer Ingersoll triangular insert feedmills in the larger diameter.
Look at iscars multi master feed mill. I use one 16mm 4 flute and dog the crap out of it cutting h13 tool steel. Then finish it out with 5 flute 5/8 acupro endmill makes 2 slots 3 inches long 5/8 deep in like 4. Minutes
Just watched the James Brutons from xrobots youtube channel (who also looked into the Johnny 5 build. nudge nudge) first go at CNC machining. actually gave you a shout out in his video. anyway It must be a relic of going to cnc from 3d printing but the tool paths most people start with are slotting with small depths of cut. this tool seems like a good place to start for beginners?

Kyocera MFH Raptor Mini (specifically .75 and 1.0) is pretty solid in my experience and 4 edges per insert.
Some great advice, thanks! I like to see how different styles of tools can be used

Really like the spreadsheet. I could do with something like that for the guys at our place!👍
i really like the high feed mills for tough steels like your cpm's and m series
I recently ran an 5/16 feedmill 7200rpm, 450ipm. In nitronic 50, it looked like it was broaching.
Cool stuff! Would've liked to see what kind programming strategies you used for the pocketing.
How do you accurately model these cutters in Fusion 360 to be able to do 3D machining?

RacnJsn95 No real reason to use one on aluminum.
High feed is built for hard material or chatter prone conditions. Much prefer high feed to standard square indexables
You have the koroloy pro x they do a high feed called hfm and hrm the hfm do small diameter ones which are really good you should have a look at them
I have always wondered how much more wear a high feed milling strategy puts on your machine.
Since you can effect avoid Chatter and the load on the guideways are consistently lower i would say that it is not so bad.If there is a better tool i will not use HFM.BUT in the last few years, i had to mill a few parts, where i was really happy to have access to this tools.
bcbloc02 It can be quite a bit less, if you think about it.
Could anyone tell me the difference b/w a 5 axis machine and Mill turn ...?
In terms of axis and where these machines can be used ?
Thank you.
Not sure why but I'm not being notified of your vids anymore.

I highly doubt it, especially in a light machine.
Good video. Looks like you’re doing a lot of slotting lately.
With enough feed speed you can use your mill as a shaper ;)
Are these high feed mills generally for steels?
Thepriest39 all sorts of materials

I have a 6 inch sandvik 210 facemill we high feed mill 120 imp and .079 depth of cut.
Dave Mcmasters .079 oh man those must be some meaty chips.
The 210's are a rough feed mill. I moved away from them and back to the Iscar wmot insert and the newer Ingersoll triangular insert feedmills in the larger diameter.

2:54 what? the feed per tooth is 0.03
ManMadeDesaster Yep. I’ve ran indexable high feed tools past .050” per tooth very reliably.
You forgot the metric guys this time. Sincerely yours a guy from Europe.
Because its basically a ball mill the SFM is not what it seems.
