I don't know if they sell this cutter, but in my opinion it is unusable!
tungaloy are the shit!!
Interesting, looks kinda like an Iscar high feed, those "dogbone" inserts, but I use them myself and have no problems at all, possible the cutting parameters are off idk
Complete failure 😩
I think you would get a better surface by placing the part on the asphalt outside and push it around with the truck 😁
😅
For high feed we use walter or dijet, great tools...
We mostly use Seco feed mills, I even made 1,5 hours of working in Hardox 450 before turning the inserts
We have a seco high feed mill which we like a lot. Also the palbit tetrafeed cutter works well also. Both can be pushed much harder than our Iscar high feed cutters and sound quieter while cutting.
nice intro
3:49 looks great 😂
If it’s Iscar FFX4, so I tried it, didn’t really like.
As well as Mitsubushi high feed cutter and kennametal.
Hitachi beat them all.
Hitachi I use now looks like a twin of Kyocera high feed. I just love it.
Hi! Have you tried milling cutters with LNMU0303ZER inserts? We are now actively implementing them in our region, they work perfectly. There are 8 inserts on the milling cutter 50.
It is possible, they are good, but we have not tried them.
Van mucho mejor los blmp0603 van mejor que los lnmu , los de AliExpress van muy bien , pero los originales de taegutec van mucho , calidad tt8080 para inox y acero es buenísima
7792 high feed from kennametal is my favorite
I spent 8 years turning hard cast iron and chrome alloy steel in the 400 -650 Brinell hardness range. Then switched to aluminium alloys for around 20 years. I would suspect the feed rate chipped one insert at the initial plunge. I have never seen that type of chip guard I wonder also if the clearance and the swarf from the plunge built up and didn't clear in time. With the chrome alloy, we had new at the time ceramic inserts and most of our people couldn't work at 300 metres per minute cutting speed. Eventually, I got up from the programming desk (pre-CAD/CAM) and validated the tooling manufacturer's documentation. Sure I took a rough cut with carbide to get through the surface hardness. I know it is tough when a tool rep is standing alongside you and your programme has always worked with the old tooling, question would be why look at something new if happy with the old tools.
Innovation Is why, never just stick to what works and is old
@@adammiller4879 Part of what I had done in the 1980s with Ceramic Inserts was talking to the two tool reps that used to visit based on the value of our purchases. One of them gave me a formula to calculate mathematical surface finish based on the Tool Nose Radius of the inserts being used. So once tested and authorised the new programmer I had shown how to do the work went through and changed the nominal feed in all existing programmes. It wasn't foolproof and other employees continued to use manual feeds. The time savings were in the region of 40%. I got assaulted a couple of times before I left that company. Yeah, my eyesight is not very good nowadays.
Нарочно так не получится) красивый рисунок)
I don't feel like indexable cutters like this are supposed to be used completely inside the material? I feel like they're supposed to have side evacuation
Looks like the iscar with XNMU inserts. I use them all the time but they aren't the best. There's one with a square insert it's a deep insert with 8 edges that I find is a much better tool for roughing. Also high feed from Iscar.
Maybe it wants/needs coolant?
A little coolant sometimes fixes issues with bad surface finish for me.
No water is used for roughing! There would be a thermal shock and the blades would crack
Good video👍

Good morning
Tetrafeed cutter from Palbit and all run safe and fast ... best high feed tool on the market 😊
Yes I agree. Tetrefeed is number one
@@CncFrezar Have a great weekend
(Hope you dont work tomorrow?!)
@dimitris ntounis Thanks! Not tomorrow, I'm not working, but today I'm at work until the evening😀
We love the palbit cutter but only one of the Carbide grades we have tried works well. We got a different grade because of stock issues in Australia and they blew up real quick. With the good grade we were facing the flame cut edges of 100 large steel plates and we prob only did one or two insert rotations on that job.
This material can be air quenched and work hardened.
The quick direction change without rolling the cutter probably didn’t help your inserts either. Same thing with entry.
If it was a feed mill or round insert, I would take 60 percent radial step over for the entire tool path. It may not have liked the channel cutting.
Also on a 50mm cutter the RPM seemed a little high for the type of the material. I would have cut it down to 550rpm.
But that’s my opinion based on very little information
You should enter in material with arc, your ae wasn't 70% but was 100%, you need to reduce your feed when your head is 100% in material and corner smoothing and slowdown is a must.
Mně na to někdy pomohlo chladit emulzí, ikdyž výrobce doporučoval vzduch. Životnost plátků se pak moc nelišila.
Možno by to pomohlo ale aj tak je to nepoužiteľné. Podľa mňa s tým nikto predtým poriadne nefrézoval. Po tých 2 záberoch už bola fréza od toho spodu fajne ošlahaná.
Cool Video
I have some Tip for you
Try a milling head from Mitsubishi Materials with them inserts
We use them in our Shop and they Are perfect at roughing.
You can rough about 3 hours without turning the inserts and you can use them 6 times
The only negative Thing is you shouldnt rough at 90 degree surface without breaking the inserts or the milling head
We also use Mitsubishi cutter, used to call them Hitachi, we use the Peco Maxi range. I have 25mm(z=3), 42mm(z=6), and an 80mm diameter(z=9). MMR can go through the roof compared to any other competitors cutters and our tips last a good time considering we also cut tool steels both soft and hard.
Also the info provided for the tooling is really good when compared to other providers. But I am aware it can come at a cost but you can try and push for their discounts 😉
Not sure what you mean by 90 degree surfaces? As in 2D profiling? Because we do that all the time 🤷♂️ the 42mm is perfect at it.
You have to try AURA D66 PHF - Vc 170; Vf6150; ap 1,8mm; ae 45mm; fz 1,5mm; 5 tooth.
может что-то не подходит друг к другу - либо корпус, либо пластины. может так получается, что заднего угла нету...
не знаю, еще раз все проверил, все нормально
Понял только , раз , два, три😂
7 seems like too many inserts for a high feed mill. Not enough clearance for chips to evacuate. Hence the recutting.
It can be
I would either try to use coolant, or try it in hardened steel
The surface it leaves is exactly like what a tool for hardened material leaves in soft materials
If that's the case coolant should improve it a bit, and/or the surface in hardened steel would be much much better
Or the edge geometry is trash, any of those could be
Everything was OK. Inserts are for ordinary steel. I wrote off the box, the parameters are in the video. Water is not used for roughing the inserts would crack.
Turn on the coolant, bet you will be amazed how good the surface finish is. Without coolant, with proper lubricants for aluminum the aluminum will build up on the cutting edges.
That's steel
Coolant on by milling steel will break the inserts early.
Is the insert too positive for HSM? I think that cutter would better suit regular machining with a larger DOC and slower speed. Maybe try something like:
VC - 150m/min
Fz - 0.15mm/tooth
Ap - 5mm
Stepover around 60%
Obviously that’s not the type of machine you do, but it’s obviously not the right cutter for your type of machining.
It looks like a high feed cutter hence depth of cut is shallow and feed fast what it's suppose to be but not so good in this case.
@@mehmettemel8725 didn’t see the cutter before hand, so I can’t say, but Judging by the performance, it doesn’t look like a high feed cutter, it looks too positive to me, I only have one high-feed cutter, but if I run one of my regular face mills at high feed it looks like that. I would try it with a low VC, low FPT, and high DOC and see how it performs before throwing it away. If he showed a good picture of it, we would be able to see instantly from the geometry
@@madaxe79 You maybe right as you say we can't see the cutter he is blurring it to not to put shit on the brand.
@@mehmettemel8725 I like that he did that. It’s honourable
Hi. It is an HF cutter
Возможно добавить надо подачу, так странно что то.
good video CncFrezar
Thanks
Add coolant..you will have a much better finish with coolant .
No water is used for roughing! There would be a thermal shock and the blades would crack
Слишком маленькая глубина резания (ap). Геометрия пластин скорее всего предполагает большую глубину. (Но в таком случае это геометрия для стандартной обработки , а не “high feed”).
Это ВЧ резак. Параметры реза я написал в видео. Максимальная глубина реза 0,8 мм. Я дал 0,7 мм
Long shank cutters wobble too much during full passes and they leave steps on the corners.
Looks like there is an insert out of positive, leaving that swirl
The milling cutter leaves traces even on straight milling, not only in corners.
get 1655 rmp 7944 feed whit 260 m/min and 1.2 pr tooth ,, its goes wrong
FFX4? mám s nimi také zmiešané skúsenosti...
😉
@@CncFrezar oko vidí 🤣🤣 ale je pravda že ja som ich mal v priemeroch 12 a 20mm...
ADD COOLANT
Síce som ešte v škole ale čosi málo viem o frézach. Keď nad tým tak rozmýšlam, jedine ako sa trieska dostane pod zub je ak nemá kam vypadnút alebo sa zamotá niekde do samotného nástroja.(To som videl na klasických ocelových frézach, triesky spadly pod nástroj a zadok frézy ich zobral) Možno keby tam mala trieska viac priestoru pre únik tak by ich to mohlo lepšie vyhadzovať.
Keby sa dalo možno zvečšiť otáčky aby ich odstredivá sila viacej tahala von.

Nie je to niečo od Pokolm-u? 🙂 Od nich sa mi sem-tam stávalo, že mi poslali rôzne zmatky. 3 rovnake telesa a jedno z nich strpalo pri rovnakych podmienkach. Akoby boli lôžka na jednej z nich vyrobene zle...🙂
Nie je to pokolm. Ale je mám s pokolmom dobré skúsenosti zatiaľ 😀
The geometry shape looks like ffx4..
terrible inserts. Also, the screws can get loose during milling!! happened to me twice.
Although i have to say the company makes some good tools for the price. But definitely no high feed from them!
Edit:
H490 ANKX/1205-FF are pretty solid ff inserts for standard H490 holders. Working good for us in 42CrMoV4 at around 150vc 1-1.5fz and 0.8-1.2ap 75%ae with a 50mm diameter mill.
Forgot about them
Ooo, it's a big fuckin NO NO.
It's better than that lathe😅

vc 90-260 fz 0.5 to 1.2 ap 0.3- 0.8 ( fz is 0.3-0.8 and ap is 0.5 - 1.2 ) if you run 1.2 mm pr tooth so I understand it sounds bad fz fz should be 0.3-0.8 maybe that's where the error comes from
I do not think so
@@CncFrezar sorry ( fz is 0.3-0.8 and ap is 0.5 - 1.2 ) i type it wrong play whit feed and speed Rmp maby the sweet comes
Pokolm High Feed cuter , pass!!!!
What did the block due to deserve this.
