I've used reduced neck aluminium endmills for deep slotting in wood. Since I ran it on a router, slotting out the profile makes a lot more sense for machine time and material reuse. It was a dramatic difference in cut quality and sound compared to a regular endmill.
You did not mention one of the most important things. With necked end mills, you are making cuts with huge Ae and small Ap, so the chips are very short. It's huge game changer in chip evacuation. Anyone who tried pocketing on a mill with no internal coolant or air with at least 2-3xD will know the struggle to remove that light but long chips from pocket...
lol, I've been necking back endmills on my diamond wheel for years! I didn't even know you could buy them pre-necked.
That was impressive. I've done some aggressive roughing in the past, but nothing like that. Having been shutdown in the past on our first generation high speed machines for unscheduled maintenance and extensive repairs, we were always concerned that our machines might blown up any minute and shut us down again if pushed.
Salesmen will tell you anything to make a buck and green managers will usually take the bait. The shop owner will be left with sloppy machines that can't hold tolerance after a few months. (We Need a New Spindle Boss....I don't know why) : (
For roughing deep cuts ,these are the way to go . Been using them for years .
Another advantage besides the necked tools for deep pocketing is a horizontal spindle over a vertically spindle
it makes my stomach churn and my hands sweaty, just watching....
Love that chip evacuation. : )
Nothing is better for hogging than a Stout horizontal and solid carbide stubs
Oh yes. That is a beautifully monstrous cut!
i have been running a Garr 3/8 Neck VRX at 175 ipm through some 4140 prehard doing pockets, along with having it helix'n out holes for some oddball size's i didn't feel like swapping drills out for the last 2 months straight, i just swapped to my second Endmill Today. No coolant. all Air. Those cutter's rock.
Edit to add: On a Makino PS105.
If I tried this at work they freak out lol. I run mazatrol on mazak smooth controls, and they have every tool possible to use already pre programed for speeds and feeds. But this is very cool and highly efficient
I buy necked (or I neck them myself) all the time for finishing walls. When you have pocket with 3mm radius 50mm deep there is no other option (toolmaking industry). Also good for finishing outer parts on small machines as there is too much deflection with long spiral endmill. better to go 2 or 3 depth passes with shorter spiraled and necked endmill.
Must be nice having HP and rigidity. But I use reduced neck all the time mainly for reach, less about rigidity for my work.
Like blue chips
Means u are doing the job correctly
Most of the heat transfered to the chips
20min cycle time is incredible
I bet the rest of the shop would not think it sounds great :)
The sound recording is not doing justice to the ear piecing screak going on there.
The boss would be smiling though.
Holy crap
That things awsome finish looks good two
Thanks man, you GET it!
LIKE BUTTER!
All about your tooling 🧰
Falalalala lala la la
Great Content As Usual Baz !👌👌
Great video 👍
Hey Titan i love your videos could you by chance do a segment on swiss lathes there is not much out there at all for tutorials.
that's a completely different level of precision manufacturing.
would love to see a segment on it however.
is that what you do may i ask.
@@joshuafeldman367 yes, many years ago and again in 2021. Swiss screw machines are intended for production runs of small precision components....but they can also produce an insane amount of scrap if they're not properly attended to.
oh im aware i ran them for about a year making dental tools and i know that they can go bad fast if anything happens to the guide bushing. I did love workin on them just because they are more of a challenge than a turret lathe. thanks for the reply.
It’s weird how addicting Cnc I if I haven’t cut anything for a few days I like go crazy haha I ❤️ cnc milling
Tell me about it HAHAHA
How is your tool life with coolant and without coolant?
Sweet as!!!
Boom
Nuts. Can you show us the tool at Max Max
Would the burrs be eliminated by running the op in reverse or would the chips have place to go ?
How is he cutting with no coolant and the endmill isn't red hot?
We are using thru spindle air blow
@@barrysetzer so awesome. I Haven't experienced that as I am only in my second year of being a machinist
Do you guys at Titans of CNC have your endmills reground or always use new stuff?
Pretty aggressive roughing? Too funny! You're just plain hogging the snot out of that material. Great stuff! Those neckdown badboys can take some abuse.
Awesome How long did it take for the part to cool down so you could touch it?
Another reason to run with coolant besides getting chips out is to cool the part to keep it from deforming from the heat.
Cool video!
Seconds as all the heat went out with the chips
If you cut perfect you don't have any heat in the part. All heat SHOULD leave with the chips although I know that's not the reality sometimes....
@@TITANSofCNC f*ck the physics, right?)
What was the material being cut? And I was always told by the tool peddler people ( That's right Bob, I'm talking about YOU) that I didn't need coolant when cutting steel.
It is in the video at 0:24: 1018 low carbon steel.
@@vsijben OK, thanks
Im not sure what you know already but here is some information to help understand these variables in cutting conditions.
Certain coatings have to be at an operating temperature for them to work as designed. Some love to run very hot on the cutting edge of the tool.
The coolant *can* thermal shock the carbide which can cause micro cracks.
At my shop we run oil because we work with stainless and titanium. It's thermal conductivity is substantially lower than water so it doesn't typically cause any thermal shock issues.
@@yamasubaruger Thanks for the info. I didn't catch what the material was in the video and the rest was a jab at my old weekly tool sails guy Bob. Just in case he saw the video and so on. I'm retired now after 32 years of doing this stuff. I do miss it though.
What about stress relief in that part?
How long (minutes) can this tool work on that hard cutting before death ?
Probably 4:41
Several hours
Not at all. We count the life of these tools in 10 hour increments, particularly in plain carbon steel like this.
@@barrysetzer epic 😍🤩
What is the power of such spindle to be able to cut at this rate
100 h.p.
@@calvinculpalt I doubt you'll actually need 100hp for this cut....
This spindle is 30HP but we’re not even using 1/2 of that.
@@wildin13 max power of the spindle. I wasn't there so I can't answer the question as to how much power that particular cut in the video took obviously
Parameters shown at 0:25 in walthers calculator says you nead about 18.8kw and 49.5Nm of torque that is about 25hp. Is it somewhat correct titan? What are your calculated and measured values?
"Sounds great" ?
Hi Barry, quick question. I'm under the impression endmills with AlTiN are best ran dry (air blast only) on carbon and alloy steels to not thermal shock the tool. However, seems like you run it with coolant when running your parts. Can you shine some light on this for me? Which is option is your preference and why? Thanks in advance
th-cam.com/video/7QEhnsV_o28/w-d-xo.html
Have a look at the video i did a week ago talking about exactly that!
@@barrysetzer Thanks Barry. So in summary, use coolant even if endmill is AlTiN :)
Haha yes sir!
I got one of those fancy mist collectors too. Its a 17’ wide door lol. Thats nice tho to keep you ac in and get the smoke out. I want to try kenametals endmills how are they priced to the competition
You can find them on the Titans of CNC online store. Take it from me, you'll love them!
Expensive but top of the line. The tools are unbelievably tough.
👀💥
Which tool holders do you guys use?
Kennametal….in this case its just a standard side-lock holder that we modified to use thru air
@@barrysetzer i have problems with tool pullout if i try and do stuff like this. A modded side lock is a great idea. Thanks for the tips
ça c'est de la fraise!!! il coupe du Z38, c'est pas de l'XC ni de l'inox mais quand même!!
Absolutely disgusting efficiency, just projectile vomit removal rate. Would make me sick to see a liquid diet fed to that monster.
Intresting wording lol, but i agree.
That was bada**
2:48 i want eat this chips
What if you used the "Laser" instead HA-HA 🤣.
How many parts can you do with it?
With what we did in this video, the tool still looked brand new afterward. It will likely make it through at least 20 more, and never actually break. Thus, the nickname Zombie Mill!
I remember when we could only cut aluminum like that haha
🤤
Man, that would take hours and hours on my tormach
man a tormach is still a really solid mill, id love to have one
And a Tormach doesn't cost hundreds of thousands of dollars.
@@larrybritzman1772 The cost of the machine is one of the last things to factor in; the total cost would be in the millions. After all, just the cost of the floor alone that can support a machine weighing in excess of 40,000 lbs isn't cheap!
@@Jack-yl7cc you are absolutely correct.
Dang that looks painful. Full compressed air for cooling? Looks like serious heat treatment too.
How come you don’t use coolant?
hOw CoMe yOU dOnT reAD
Filming.....................
Do you guys not hear the chatter or something? I can even see it on the walls of the part. How does that "sound great" to you? Can't imagine what the shop sounds like if that's the sound you're going for...
That is clearly a roughing operation. They would have to leave stock on the walls and come in with another endmill to bring the part to final size. Most of the time is usually spent on roughing and it looks cooler so they show lots of flashy roughing in their videos.
@@sbeprecisionproducts6729 chatter dramatically reduces the life of tools, tool holders and spindles. It is not ok for roughing. I get that they’re trying to show high removal rates, but it just looks bad when the cut is unstable and the tool is singing like a bird.
@@jackkara91 because its commercial video, so clearly there will be "no chatter" and "sound is great" :D and of course boom boom boom :D
One part - one tool?
Tool still looks brand new!
You are going to need to come in with another tool for finishing most likely. No matter how new that rougher may look it wont give you a nice finish usually unless you are doing short runs in non-abrasive plastics or something like brass or aluminum.
Yes, this was roughing only!
Chatter is awful
It sounds horrible....
man it doesnt matter when you pushing your tool this way too hard . :D
