High FEED Endmill on Hurco VM20i
Вставка
- Опубліковано 10 гру 2019
- Here we are using a Millstar endmill (high feed) to core out A2 steel on our Hurco VM20i. So impressed by these tools!!
Check out www.dansdiscounttools.com/ for many tools like these and great deals!
Seriously... I love a man who has passion for Engineering/cutting metal. And I honestly admire all countries, people or individuals with the interest and energy who enjoy it. Engineering should be more than a wage. It should be a pleasure too.
YESSSSSSSS! Thanks Neil!
That is Crazy!!! How?? Thats so impressive. What an amazing tiny tool.
Its chip thinking on the bottom of the tool instead of the side.. all the cutting force is directed axially up the spindle. You can do long overhangs with high feed milling! Same principle for big indexable high feed cutters as well
Lots of similar options in metric tooling. Mitsubishi has had similar hi-feeds for years now and they're top notch tools. We use them quite a lot for hardened steels up to 62 HRc.
Great video
Cool technique!
You should move your table to the Door in Y in your post process. Save you from having to move it every time you open the doors.
Hey thanks for the shout out on the end mill! Let us know if you need anything else!
Excellent work good operation and facilitate the development of the project greetings from mty nl Mexico
Impressive, I've been wanting to try a high feed cutter.
I'm not sure if you just forgot or didn't know. With a position block, you can tell it to bring the table to you. After you get your part setup X and Y, jog the table where you want. Then take those part coordinates and put them into your position block.
@horseshoe, good point. not sure why we didn't do that.. ALTHOUGH one concern i did have (and this comes from building jig grinders with roller ways, is to not brinell them by hitting table or shipping the machine with the table on!!! So I tried to move the machine to a different position every time we hit with a mallet so the roller bearings didn't always brinell in the same exact spot.... Really not sure about how good that is for the longevity of the machine to hit table/parts with a mallet. Great point though sir, thank you!!
What do you/ or guys think about the severity of hitting down your parts? Does the vise/table having enough damping to protect your linear guides? Obviously a rubber mallet is better than a hammer... but still... you lose sleep over these things when you are trying to take care of your equipment.
@@MooreCNC, when I need to seat a part down in a vise, I do the following.
Lightly clamp part, maybe 10 foot pounds. Then tap down with a small dead blow hammer. Finally tighten vise to working pressure, 20 to 50 foot pounds, depending on clamping needs.
Our VM1 is a 2006 that we got new. Can still hold some crazy tight tolerances on it, when needed, without much fuss.

I don't think that's a thing to be concerned about at all.
Your hammer is tiny and light compared to vice and workpiece - and even more compared to the whole table assembly.
I'd bet you don't even put on a load by lightly smacking it with a hammer that's anywhere near significant compared to the preload forces of regular four row two point contact bearing blocks.
If I'm not completely off here, grinding machines and similar often rely on the weight of their table for preload/generally have very lightly or non-preloaded roller or ball bearings.
They're a completely different pair of shoes.
we used to do that on a cnc lathe up to 14 inches and 2 inches thick in 2 minutes 15 years ago 316 s/s
You could shove three Q-tips in the groove at 120° and hit them with crazy glue - that way the slug can’t shift and pinch your tool when you cut through the other side.
Nice 👍
Just a thought but dependent on your tooling you could use a face groove tool on a lathe for the first op coming 2mm from the back face and then just mill out the 2mm should reduce your total cycle time considerably
Tom Pass you are right about that, we trapanned on a lathe the second time around doing this job. Unfortanetly the smallest face groove tool we could get was 4mm wide HFPR from Iscar, so we did not get as big of a slug coming out, but yeah cycle time went down 1000 percent. But this video was mainly to showcase this endmill, for instances when you cannot treppan on a lathe (like a square pocket)
"I think I need two hands for this"
* Swaps to left hand *
* takes it out without an issue *
I think there is tubing with that Wall thickness.
sup man, very cool stuff, are you still active on here? Havnt made any vids :)
Dear Moore CNC! I'm European, i have a question: you Feed is 183. This What unit of measure? I'm trying to calculate your technologie.(Vf=inch/min?)
Have you tried trepanning. I could do that in 2 minute... no joke.
On a lathe? I have a face grooving too I can try it with. Can a .125" width tool go .75 ? Deep in a2. I know I have a 0.25 wide tool that can, but I also know it doesn't like to be buried that deep... maybe I will try that out next time because it would be cheaper than these end mills. Thank you sir
Dave we did the same thing in about 2 min in 316 s/s all different sizes up to 18" doing them like that your soon go out of business
What is ripping that into chips with e.m. vs. Cost of slug you're saving and the time saving vs. high feed mill. 15-16 minutes is not quick for what you're trying to accomplish
Эко чудо, Вам бы на Российский завод, там бы увидели чудеса. Йентой технологией, для экономии, ещё наши прадеды занимались.
What toolholder held the tool? Was that a Mari hydraulic?
@Zack Macfarlane. This is a sandvik corochuck. But we also have Mari, schunk, yg1, BK. All are good
Halooo. Sorry if I'm missing something?.... That helix function has been available for years.. ie.... 10 inch diameter hole, .625 diameter cutter... 4.6775 centre line program. Round and round and round and round! Set maximum cutting depth in the helix segment, then go round and round and round 🙄. In theory you'll leave 20 thou as finish cut. (in diameter). Obviously allowing for push-off. Just make sure you have control of the slug when you break through.
I was excited in this video because a normal 1/8 end mill would not be able to do those feeds and speeds at that depth. I was not showing a new way to program. I agree you are correct in leaving stock for push off.. we leave even more Incase the endmill breaks and gouges
I do acknowledge the relieved flutes aid swarf evacuation. Which is why the particular cutter is available as a purchasable item. (In UK anyway, where we are far ahead of US in manufacturing methods. Because we invented the whole thing).
I heard a FACT? many years ago ..... The Americans produced the smallest diameter drill ever seen! They sent it to us, in the UK so we could admire this marvellous thing?
Well, we drilled a hole, straight down the middle. And sent it back to the USA!
I understand your story.
And it is a Good Story ??
Seems i remember this story from years ago.
Except it was the Japanese that drilled a hole through this tiny drill you speak of.
Taking nothing away from the English Engineers which i consider them as in the top 3 in the world.
In NO particular order.
The Best of the Best list.
Germany.
Japan.
England.
I sought lied about the order ??
Germany first, because they don,t talk about engineering.
They just do it.
Same with Japan.
I learnt my trade from some excellent English and Scottish tradesmen.
Lost skills that could Never be replaced.
Neil Woodward , you correct sir it was Presto Tools in Sheffield
I heard the story that they sent it to Switzerland and they drilled a hole thru it and threaded 3 other drills into that hole.
