On mazatrol mills we switched from an end mill to an insert endmill that way we could switch from carbide to ceramic depending on material type. Then we would flip the insert corners for the finish pass. Saved alot of money I was told.
I've had good luck with ceramic mills as long as it's not an interupted cut.
Good video showing the chips taking the heat away from the part.
'When implementing tool management, make sure the machine can swap tools in the middle of a cut, or change the tool before it runs out of time. Older machines would use the tool in a 30 minute cut (for example) as long as it had 1 minute left on life...
We implemented a guy who loads parts and comes looking for me whenever a tool starts getting harsh with the parts (I take them off the VMC and onto the knee mill and my "5 axis lathe" they go)...He even occasionally checks the spindle load!
The advances in ceramic technology have been unparalleled in any other material science in the last 20 years...
not really related to the video, but plastics have also gotten incredibly good the last 20 years, and definitly the last 30.
Glass as well but lots of similar information gathered between the 2 of them
I would have never thought ceramic would work as an end mill. Hanging out there like that with so many vibrations. I would expect it to turn to dust on contact.
Nope, speeds and feeds, and length of tool. Actually last awhile
For true roughing I'd say carbide has the win 90% of the time. Semi roughing where you are using less of the cutting edge , be it milling or turning, ceramics probably have the win with good tool management.
Ever worked with inconel material? No you have not
@@louisrousseau1006 yeah I have actually, in the last five years it's been 90% of my work. Aerospace , oil and gas components
@@louisrousseau1006 I am right now. Ceramic all day for roughing. 😎
Tool group management is awesome, first time I used it was in 2008 and it's a lifesaver turning threads!
Titan!. Love all your videos!! I am employed on a fast growing tube aerospace company (Mundo-Tech), that outsources a lot of machining! You have helped me bring profit to our company With your academy program, which is free BTW.. with your CAD,CAM tutorials, I would like to share some ideas with you, and for you to help me continue to build our machining department.
WOW dude, get off their nut sacs. This channel is a joke compared to real life machining applications. Been doing this shit for 30 years and this crap is elementary at best...
" . . . and it really just depends on what you're doing, right?"
As it does with all tooling choices, my friend. Everything has its strengths and weaknesses.
Could you do a video on ceramic turning? I overheard some guys at my shop talking about trying ceramics but they didn't know much about it
Beautiful cutting ✂️👍✂️👍✂️👍👍
Ceramics need to be ran much faster feeds and speeds than carbide. That’s where many get too conservative and the tool doesn’t last. We had our vendors tell us the correct way to use them in our materials and our engineers balk when programming it. And dry. No coolant or the damn things will shatter
Hmm. Interesting. I wonder if running them hot basically makes them tougher and more shock resistant than running colder...
Wait till you learn that carbide is a ceramic
LOVE THESE DAILY VIDEOS OF KNOWLEDGE YOU SHARE!!
Les carbures de tungstène sont déjà des céramiques, quelles sont les différences avec celle-ci ? Merci et en tous cas très impressionnant,
Ceramic blows tungsten out of the water for parts harder than 48HRC~. I work with steel that can push 60-67HRC daily. Use to use tungsten taking 0.2in cuts at roughly 250sf/m. Now Im using ceramic taking 0.6 cuts at 350sf/m. And what's great is the ceramic can be ground back into shape to be reused much easier than tungsten. Tho on anything in the 40HRC or lower.... Lots of chatter.
Would ceramic work with hardened tool steel? I use high grade carbide, but I'm curious on other people's experiences
Never tested, but as I understand it, ceramics mills work by heating the metal so much it becomes soft, and then removing it. This heating might be bad for steel, screw up the temper, things like that...
Or not, it's just a guess. If you find out, let me know!
Tool steel is soft if u know how to cut it. If the chip is purple there’s too much heat. Blue chip is what you aim for. Never cool it with coolant as it hardens the material. Always use air blast.
@@supah_sonic9979 I work with m390, that stuff is extremely stubborn. The only chips that turn blue are the ones that come from burned mills or inserts.
@@andredepaulagomes that makes sense. Not the very best thing, but definitely something I'll discuss with my tool provider!
Never tried it, but I think the reason is that for a 1/2" tool, Kennametal recommends up to 3280 SFM in inconel. So I would imagine for steel it would be like 10,000 SFM, and unless you have a super speed (like 50,000 rpm+) spindle you'll never get up that high
Had my first encounter with H99 a few weeks ago. Only took me an hour to figure out what was going on and find parameter 13265.
You also make it up for regrinding and recoating the tool,,,usually about 35 bucks a emill
Can you use an old cutting piece to make a rough shape to save money ? Rather than using a new cutting piece you use an old cutting piece to get most of the metal off.
That's a fairly normal approach, using a fresher sharper tool for finishing and cycling it into a roughing 'job' as it loses its ability to make a fine finish. The problem is with more exotic materials and their tendency to work harden and be negatively affected by dull cutting tools. In those cases you just use the best, otherwise you could bite yourself in the butt with the false economy of using lesser tools on an expensive part and scrapping a work piece. Sometimes paying a little more upfront saves you big bucks down the road.
Would using coolant with the ceramic mill be a waste?
Yes, ceramic is chemically inert so milling it does not heat the tool up so it’s not an issue.
We need more Barry videos!
A question the first Mills why you didn't add the water?
Not needed with ceramic endmills. You run ceramic dry.
Isn't carbide technically a ceramic material?
I know, I know, but....
It is. Same with silicon carbide. The so famous ceramic break disks for example are mostly made out of silicon carbide.
Nice Job :) #DuplexCNC
I am more curious about a 1/4 drill bit?
Its all about application. I cut materials that ceramics are my only option. Plus, lately, carbide products have been mostly junk.
beautifull exaple how there is no one solution for machining. each job is different and requires different tool to be as fast and efficient as possible.
Hi Titan! What do you think about Cryogenic Cooling plus ceramic cutter and cutting time control(sister tools)? Espacialy cutting titanium with deep cavities... May be safer chip removal with Cryogenic Coolant thru spindle/tool(?). All the Best for you and your Team! 😎
Shrinkage??
@@kingofkings600 Shrinkage... Maybe a problem / Parts with tight tolerances. But for roughing, heat avoidance, longer cutting time it is a good solution...
This is just Taylorism, something everyone working in manufacturing should have a decent understanding about.
1:04 if have material to move then better huh. then its allways best choise. there is just catch why they sell anymore other mills LOL. ceramic is used for hardned material to finish on lathe lol, why is now good for move alot material lol
Boom
No coolent?
Carbide is a type of ceramic...

The info in the video is great but the sound quality it pretty lagging. Specifically compared to the sound quality in the normal videos ( could easily had Audacity run in the background and recorded his mic input and people would still hear him in his call)
Ceramic sucks if there's an interrupted cut.
成本咋样
@@importanttingwei7747 智障,我是问成本怎么样,我还不晓得这个是陶瓷铣刀哦!
@@user-xq7gu2pq4d si
no
You said "Actually" 147 times in this video.
Mild steel for me all day long. It worked for me 30 years ago, & I wouldn’t use anything else!
Try copper tooling ... it looks nicer ! 😌
you should just flag this one as one long kenn*metal ad- too blatant, you can do better
This cnc shop is best on TH-cam...kennametal tools are 🔥
Yeah, I would definitely hide the identity of the manufactures of the machines, tools, coolants, software, etc., that actually have been shown to work the best in a given situation, so that we actually gain no helpful information from a particular video. Good plan, Bob. 🤐
why does kennametal make you so bootytwisted Bob ... tell us where it hurts and why
@@kingofkings600 kennametal is good! Have you ever worked with Sandvik Coromant Tools? My opinion: kennametal is "Ford" everwhere in World you can find it. But Sandvik is the "Mercedes"... especially in hard cutting. Even "ph HORN" tools, made in Germany, are a very good solution for difficult machining...
his videos over the years have gotten to be more and more like advertisements and not a mix of content. sad to see. he should do more instructional videos and not just hawk products.
to each their own.
