Tool and material science is crazy. Part of my job is to program an 8 axis grinder and grind custom carbide tooling for my job. Mostly regrind work, but we get special projects frequently that require custom tooling for when we do toolroom work.Even a slight change in little things like core thickness, gash depth, or comb relief angle can make a huge difference when we use the mills.
Love that TE cut where you can see the head moving WOW what a tool
It must be part of the toolpath, it wouldn't cut w/o chatter like that if the machine was so flimsy that you could see the head moving because of the cutting forces.
@@MF175mp It's just a slotting tool path, a straight line, so what you see is the wobbling.
Yes, the entire spindle head is wobbling, but the tool didn't break, which was the main point, alltho you wouldn't want to use it like that all the time :)
Isn't it pulling down the pull stud? The mill is biting so much it is trying to pull the tool holder out of the spindle
@@bluustreak6578 You wouldn't run it like that at all, it's gonna wear down your spindle in no time. But for demonstrating the toughness of the endmill, it's pretty damn cool haha. Wouldn't run my machine like that tho
Do we have another video of that big titanium part being finished? I think there were two pretty long videos of the roughing, but I'd love to see it get finished up.
Changed the wife's photo in my wallet for one of the Harvey.
lol 😆
this is an old video but you sir have changed the way i program. my dad taught me how to program and i think he did very well but i showed him how to do it fast. its a great blend of knowledge and want to get it done faster. im the faster part. he is the this is how it works. anyone can sit in front of a screen and say yep that it send it. but you have shown me and us how to just hog.
thanks titan for letting me know that the importance of flutes and milling technique
Watch the HARVI 1 test on DUM 50 at 4:35 ,it moves with the tool holder. Is it caused by a trochoid path or low spindle rigidility ?
its caused by ramming it into the steel real hard xD
@@bsod4144 That doesn't answer his question.
The movement you see is not programmed. This movement was there because we exceeded the bending moment of the spindle connection. So not what we would desire, but a real testament of the tools capability. It is so tough that it even survived the spindle flexing during the cut.
When it do this with HSK63 then I would like to see what it would do with the CT 40 taper.
@@dannydavis705 Thanks you for explanation.
I thought porn wasn't allowed here.
Love your enthusiasm!
Kennametal is the Walmart brand of tungsten carbide
@ Titans of CNC I wish you would do a video on KOR -6 and how it compares to Harvi 3 and Harvi 1 te
Is the Harvi TE better at slotting because the flutes are beefier (i.e. since there are only 4 each flute is thicker) so less likely to chip and break? Not that I will ever be slotting a 1" end mill into Titanium or Inconel on my Tormach in my basement, but always like to learn about end mills. Your videos have definitely inspired me to take full length DOC when contouring or 2D adaptive. Working my way through the building blocks, and figured well Nicole is taking deep radial cuts on her tormach, so so can I (maybe she can make some Tormach videos from home?). Stay safe.
There are several features that contribute to the Harvi I TE ability to full slot. But the main thing is that the lower flute count makes more room for the larger chips generated during a full slot operation.
More flutes equals higher strength as the flutes are not as deep giving you a bigger core. Core diameter is if you ground the flutes off to minimum cleanup leaving the solid round core left. Fewer flutes are cut deeper giving more chip clearance allowing deeper cuts in softer material but because the flutes are deeper the core is smaller.
Love your videos but your spindle bearing must hate you lol
Those bearing can propably take a lot more
But yea the spindle wobble is a bit concerning
Is there one like this one but for aluminum to cut straight slots like for making a heat sink fins?
Hello,
Can i use those tools for stainless steel?
Thank you!
Absolutely you can.
"There are no better end mill on the planet..."
Don't try this shit if you own a vertical or horizontal milling machine with less than 20HP and get no decent fixture. In this case there are no end miil (any brand) on the planet to make BOOOOOMMMM!
Lmao that spindle does not like that depth of cut
Thanks for this video!👍
Made in USA, excellent
4:27 is that lateral movement part of the path or is that pushing the machine past it's limits? It doesn't seem to continue all the way through the path. In the second shot 4:37 sure looks like the spindle is flexing
The movement you see is not programmed. This movement was there because we exceeded the bending moment of the spindle connection. So not what we would desire, but a real testament of the tools capability. It is so tough that it even survived the spindle flexing during the cut.
Nice sir
I would be interested in seeing how they make the HARVY,. When restrictions are lifted.
Sir can you please uploaded a MM THREAD MILLING manual program it's easily to understand so for please upload eg any MM THREAD like M20 M33 M24 Any one iam waiting for your reply sir please
Are they using a coating Titan? They are a work of art.
Proudly Made In The USA!
where do order harvi end mills
is that tool holder flexing at 30sec in vid???
Please! Subtítulos en Español
Quarantine man, what's going on?
ouch. the Harvey 3 there is a $600 item... don't break it
Do you regrind your endmill???
Yes, we can recondition these endmills
corn cob
Can we use harvi 3 on aluminium?
Prasad Sonawane I mean you can, whether you should is a whole different question
Please use the KOR5 for aluminum. This endmill is designed for aluminum and productivity
Of course I love what you're doing for the trade and most of your videos, but I gotta say I'm a bit disappointed to see Autodesk and Fusion have been left of your sponsor list of your videos the last couple months. You explained a while back that you would be using and teaching both but now it appears Autodesk has been replaced.
A lot of others on YT are using fusion and plenty of those videos around. One that gets far too overlooked is Gibbs Cam and integration in importing solids. Far as cam and great toolpaths Gibbs has a fantastic software system that can be tailored to the user. I like modeling in fusion and inventor but tool paths and selection are not that great.
I just wonder what to do with the shavings - it must be a load of metal chips..
Há não cara muda o disco....já faz dias q mostra a mesma coisa!!!
Hi sir
Is that a reality? Boom?
Tgat slot wasn't good for the machine it was snaking
So what tool is used to make these endmills? It's like asking what created God.. lol
Sintered tungston carbide. Diamond ground.
Brandon Bartkowiak yes with a gashing, flute, and OD wheels for that sweet sweet endmill
Hi titans I think I want to invite to my company because I think you have a DSD in my company mise and I want you to come I’m only employer But I saw a problems maybe you can help us
Helix angle is different
ACT PROFESSIONAL THIS IS AND HAS BECOME A JOKE OF YOU TRYING TO ACT .....AT ALL JUST TALK GOODS OK?
