Insanely Fast CNC Machining Inconel 625 w/ Ceramic End Mills | Pushing UMC-750SS to the Limit

[@alexkern9134]

Hey Titan, so now you've shown us how to rough, how about finishing? If you're bored how about a part with some deep pockets like you talked about? Can you ramp with ceramics? Thanks!

[@01srob]

Ceramic endmills aren't made for finishing only roughing. They don't seem to like interrupted cuts but ramping is fine. They are great for removing a lot of material quickly but you need the spindle speed, he is running 15k here which is probably the slowest I've ever seen someone turn these. I have a 5axis OKK with 20k rpm's and even that is slow. I typically run Mitsubishi and they recommend 25k+, but hardly anyone has that all the machines in our shop are either 16k or 20k.

[@athrunzala5337]

@@01srob is ceramic actually cutting metal or eroding it to need these extremely high speeds?

[@01srob]

@@athrunzala5337 Honestly I don't know for sure, that's a good question. I would say that its probably a combination of the two, the chips are very fine. The endmill itself actually erodes as you are cutting so you are progressively cutting with a smaller tool until it breaks.

Hello Titan ! Big fan of you and your work. One question for you : How long can you run that end mill , or how many parts shown in a video could you make with that end mill ? Thank you.

[@StefsEngineering]

so how many chips where stuck in the front of the gopro housing? It got peppered quite good!

[@BrilliantDesignOnline]

I am still blown away the bit that was white hot on the Tormach was not a puddle. It would be helpful/interesting to know what the parts you are making are, because I cannot imagine what a star form out of Inconel would be for.

It is insane, such speed for machining Inconel.

[@pand0ras]

All the Sparks and the glowing tool is basically a part of the energy which comes from the spindle. Think about how much energy is used, just to rip some metal appart.

[@curtiscap529]

time is money, it takes a long time to cut that kind of material with a Regular Carbide Endmill, which in turn costs more in tooling and power, as well as time. which in the machining world, is money.

[@CalvinoBear]

About 20-30 horsepower, not much more than a regular car at steady state.

[@astriknon]

I have never worked with Iconel, is the burr that this endmill making normal with Iconel, or is this a result of the tool and or cutting conditions?

[@balooc2]

its kinda funny trying to explain this to somone who is a selfproclaimed expert on other platforms when someone links a webm or gif of a ceramic mill doing its thing! "WHERE IS THE COOLANT" "HURR DURR?". LOVE IT! great vid!

[@MrDJDreamon]

Hey Titan. As a seasoned machinist I'm looking at the footage while listening to the explanation that ceramic is chemically inert while the mill is still glowing red after the long cut. That tool is red hot but cools down quickly is what I see....

[@jakemontana7125]

Niceeee! Love your channel titan, hope you and yours are well and safe.

[@viejitogringo]

How do you keep the red hot chips from melting the plastic enclosure or gaskets and seals???....... I can see it destroying the laser tool setter on my dmg dmu50

[@NicosM51]

Same here. Seems terrible for the machine. And a definitive nogo if you don't have a machine accomodated for abrasive dust making processes .

[@Iscariot18]

Hope you guys like them, they're a bit of a pain to make.

[@JoeMalovich]

I wonder if you can machine it under a nitrogen purge so the chips don't oxidize?

[@soundspark]

Would there be any point to doing so? The chips are barely oxidized, ending up only golden in color.

[@bluustreak6578]

Hey Titan, with such precise chip loads like these, do you take chip thinning into account? That would make a huge difference with these small radial loads :)

5 axis ceramics! And could you explain why the ceramic not only can withstand the heat but I guess work better extremely hot?

[@Imba-gt7qi]

Bad for coolant-manufacturers, good for making firework :-) Sometimes the tip of the ceramic glowing a little bit. But hot ceramic cuts better. With the half rpm the Cutter will melt.

[@opendstudio7141]

Most of the time it smells kinda like a stainless steel sauce pan that has been forgotten on the stove. Sometimes a mix of coolant and oil. Depends on how clean and old the machine is.

[@andistangl3425]

can you run ceramic on machines with cutting oil or will it catch fire

[@hocln2556]

dont cool ceramic mills... If you cool them you need always coolant on the ceramic or the ceramic will burst PS: Never used oil with ceramic, but normal coolant emulsion you can use

[@marouanebenderradji137]

cooling the ceramics is a bad idea because the thermal shock would break them (thermal shock is not good for ceramics and also the way that ceramic tools works is totally diffirent from carbide tooling the edge is designed to maximise friction and generate as much heat as possible so that the material will loosen up and softens till it becomes partially melted than the flute geometry will evacuate and thats why they never cool them just some airblast or through tool airblast to fly those chips away and search for articles about this subject, greenleaf is one of the leading companies in tooling recerche and developement chek their website as well

[@ye545674415]

thx for sharing, btw can u provide a parameter chart that which is in ISO unit.

[@keethansinniah256]

Just wondering, isn't it bad for the machine to not have coolant on. Or does the use of a ceramic cutter make using coolant not needed

[@astriknon]

I turn with ceramics often and I do it dry as ceramic is sensitive to thermal shock and could easily chip or crack, due to rapid heating and cooling. Also I generally turn hardened tool steel, so heat created at the tool/part interface anneals the steel just ahead of the cut so that it can be removed easily.

[@mitsmillman1652]

Good use for a crappy haas 5 axis :)

[@cian-lukechristoff7771]

[@NicosM51]

.01 mm feed per teeth and metal is molten down out of the part. I can barely call the residue that come out of this operation a "chip". This is in between machining and grinding.

Great titans

[@Davemcmasters]

Hey titan, do you like those hydro force hydraulic holders? . Long story short the guys in my shop all have less than a year in the trade and dealing with collets being tightened to much I'm thinking of just using all the hydro force holders

[@LienNguyen-sw7kb]

Maybe try get some torque wrench to help with over tighten collect. Those hydro force holder are expensive. If you afford them go it. They are nice.

[@cembellsteve]

Best thing to do is give them shorter wrench. All we do here is drill. Every drill is put into a hydraulic holder. My guys found a way to "F" that up as well . The screw you tighten to build up the hydraulic pressure gets bottomed out. Over time it will get messed up as well. But i know where you are coming from. my guys think the tighter they have something the less it will chatter. No FINESSE!!!!!

[@MO-zu9xq]

Hydroforce holders are fantastic and they are great for idiots. I use them in high production with novice people who are not machinists. Adjustable axial hard stops are perfect and they are resistant to people not cleaning properly due to tight tolerance fits. Collets are affordable. Holders are balanced well and can do anything from precision reaming to rough hogging. Love them.

[@Davemcmasters]

@@LienNguyen-sw7kb we have the torque wrenchs and I am the only 1 who uses them. So I know which tool holders I have touched bc I dont need a 3 foot breaker bar to loosen the damn collet.

Hey Titan! Can the end mill be used on Aluminium?

[@lukaskopp5914]

No the fluts would instantly be filled up and it would break

[@hakont.4960]

High speed steel works well for aluminium AFAIK.

[@nerd1000ify]

@@hakont.4960 most aluminium is cut with carbide these days. It just needs different tool design from steel: higher rake angles and very sharp edges (carbide for cutting steel is often deliberately blunted slightly to increase the strength of the edge, tools for aluminium must be razor sharp) and no aluminium containing coatings that could bond with the chips.

[@hakont.4960]

@@nerd1000ify I guess I learned something new today.

[@gerrylundergaard60]

Nice to see someone still using the old school stuff! Nostalgic brings me back to when we developed the plasma rifle in the 40Watt range back in the 80’s. Pro tip: you could mill into those soft jaws for greater workpiece rigidity and thermal stability through crystalline non amorphic stock. But if you knew that you would also know the difference between a Haas and a Japanese machine. Or a Buick to a Bentley. Keep up the good work kid!

[@danl.4743]

The ceramic does not transfer the heat.

[@hakont.4960]

@@danl.4743 I'm guessing the air passing over it as it spins also gives some cooling.

[@MO-zu9xq]

Heat leaves with the chip so long as you are moving at proper (fast enough) feed rates. + what the other guys said.

[@PBMS123]

how is the fact it's chemically inert make it immune to the laws of thermodynamics. It can certainly heat up. Maybe it's not likely to have any oxidation or be affected as much by heat, but it certainly does get hot.

[@primitivetf1542]

@Titan does coolant increase the tool life of ceramic?

[@swikocki]

Might be like CBN, best run dry as coolant can cause thermal shocks to the tool.

[@remodz6385]

No, you run ceramic dry always.

[@brettwalkom948]

Sudden heat change with ruin the tool

[@soundspark]

I'm sure if you do this in the Haas every day it won't last too long, unless somehow the toolpath is designed to limit pressure on the linear ways.

That orange glow is normal, it's just a byproduct of how ceramic wants/needs to be run. If you try to turn on your flood coolant you will thermal shock the endmill and destroy it.
