also to improve your results with facemills make sure the width of your cut is not more than 80 % of the cutter diameter also cut a bit offcenter to reduce vibrations
When you cut with and multi insert head like that one if you want a cleaner finish check each insert for depth with a indicator base from the bed and fine the closest cutter to the bed. Then shim the rest with shim stock to match the lowest hanging insert. You will fine that the head will be a lot smoother in finish and sound.
That machine is quiet like a new one! Besides tramming you might check the adjustment of the gibbs sometimes during rapid traverse the table can tilt a couple thousandths... Always worth checking them all when you first get a ne machine... :o] O,
Yes, I really like the smooth running. I can even hear the music while working now. I actually know that at least the x-axis gib is too loose. The table vibrates when cutting unlocked. I haven't had time to do the adjustments yet but I will soon!
Go faster when milling. U can take at least 2.5 mm off with way quicker feed and rpm. Index them inserts to damn. Make sure you don't have high inserts ur getting a lot of rubbing from chip build up
Yes you are right! I could have used way more feed. I think the speed 800rpm is good though. There is a problem with the axial bearings in the spindle. Thats why it was rubbing. Also the universal spindle only has 3kw of power so it really isnt much for deep cuts with high feed.
If you just rub it , you ruined it....Thats why your inserts are fried . If you too a cut at .25 deep at 150 rpm and 10 in feed , it will throw the vice off the table with those wimpy clamps. get a stronger setup. 40 taper mills have no ass. You will never get that to work on that mill.

I'll be back....
At that spindle speed if you have the horse power should be good at about 30 inches a minute
500 rpm feed 300mm cut depth 4 mm.

I use aluminum foil to get them within 0.01mm

Lift the tool after a pass like that what do you expect.
Like watching paint dry, head is not parallel to table

you can do 0.1-0.2mm per teeth
You touch the material while the cutter is running and very close to it. Very dangerous.
anna mennä kovemmin, jos sulla on kierroksia 500 niin 50x hampainen määrä on 0.1 syöttö per hammas. sen tuloksen voit hyvin tuplata tai triplata
Kuten tittelikin sanoo, niin tuohon aikaan ei ollut tiedot ajoarvoista ihan kohdallaan.. Nykyään vähän paremmin!
What model milling is that. Its a beast
2:25 LIFT THE TOOL PLEASE!
This is more of a "how not to face mill" type of video anyways :-).
More speed and feed , and some lubricant fix the problem
Speed is somewhat ok but feed is way too slow. No coolant for face milling steel.

Please look at my newer videos and also read the title of this video :-).
6т83ш type of milling is a best
HEAT BECAUSE TO LESS FEEDRATE ;)
Head needs Tramming ??Nice work
Yeah. The marks when returning the table by rapid traverse also indicate that there is something loose. There certainly is room for improvement!
buddy machine is good . cutter is good. but you don't know the parameters of cutting
Did you read the title of the video? :-) Check my newer videos!
Ok. what was this test for any way. wrong speeds and feeds?. more appropriately you should mention inserts.
feeds to slow .. 540 rmp 0.15 -0.2 pr teen 3mm depht chips fly off
Don't get it...why this post...showing us how to wear out the inserts in no time?
This was when I had no idea what feeds &speeds to use :-).
