Fun fact: Run the RPMs too high and those glowing chips auto-ignite like magnesium and turn into pure white fireballs. Found that out the hard way and nearly burned down my shop.
I wonder if it's not just the machine oil catching fire, unless that chip hits over 1600°C (2900°f) I'm not sure, mineral oils and most machine oils flash at 225°c (440°f) , or that thing was spinning so fast the friction got it there, I love science man
@@penners-make-content titanium alloys only require 2200°f to autoignite and titanium alloy dust in the air (when mixed properly) requires 480°f to autoignite so it's definitely possible and that's a big reason why titanium alloy is suggested to he machined under constant coolant flow.
I machined titanium for many years on a Webster Bennett vertical lathe. It is very hard material to work with, but the right speeds an feeds makes a big difference to how long the inserts lasted. Also having suds on constant gives a better finish and helps the inserts last longer.
You ought to see the speeds and feeds they are running on Titans of CNC. They use a lot of Kenametal Harvii 3 carbide end mills. ruclips.net/video/IjZrHAo2Wvw/видео.html
In my hometown, a local recycler had a very large shed that housed all the “exotic” chips and cuttings. There was a fire in that building and I’ve not seen more nervous firefighters in my life. They got it put out but it all just about exploded.
@@barneylinet6602 no, the TiO and TiN are to stop the metal being machined from sticking to the tool, which is why you use drills and mills with different coatings depending on what you're going to be machining.
@@ObservationofLimits It's used on motorcycle fork seals (higher end stuff) as well, lubricity is a smaller part of it, the resistance to chipping/stone impacts is more important.

Used to joke in Rolls Royce that it could make a profit out of the amount of swarf that came off every component. Huge forged rings would come in and after the 40-50 operations the finished component was about a 1/10 the weight.
A lot of tool shops literally do make a profit off the swarf. They might break even on the job itself, but extra material and chips are written off the books completely and the scrapyard return is pure profit!

I've heard that these titanium chips are highly valued by safe and vault manufacturers because they imbed them in the concrete used to line them, making it very hard to drill into them.
I've heard the do the same thing with broken carbide inserts, drills, mills, taps whatever. Atm you get around €12 a kg, roughly $13 per 2 lbs here in the Netherlands.
@@pinocolada4254 I came up with the same idea, when designing my next house, which would have a vault in the basement - just mix into the mortar used to fill the concrete block, and it would pretty much ruin and demo saw blade trying to cut through. As an extra level of making things difficult, line the inside of the space with 3/8" stainless steel, because you can't cut stainless with an Oxyacetylene torch.
@@machinist7230 you are absolutely right. You could also sandwich a couple of grades of steel to the outside of the vault. Maybe with an air gap in between. Something like what the Americans call AR steel, (comparable to what Europeans call Hardox) and manganese alloy steel. That would also be brutal on any saw or cutting tool. Even lining the 2 with a non flammable, fibery fabric to seize up saws and drills, and a layer of concrete with carbide after that could be done. Burglars worst nightware.
I used to do business with a shop called Metalex in Cincinnati. Once there I saw them machining a large billet of solid titanium. They told me it was for the main fuel pump on the space shuttle that has the capacity to drain an Olympic size swimming pool in 10 seconds at full power. Those billets were X-rayed and handled like fresh fruit all the way through the process. Not so much in the early stages but when you whittle on something around the clock for days, the chips made are more and more expensive and the part becomes exponentially more valuable. They would not tell me the final price but just doing some basic shop math can get you close. Not only just the machining, but aerospace components have to have extreme traceability and the paper trail alone requires a full time employee. Every gauge, every single caliper or indicator used also has to be certified.
Titanium is the 2nd most abundant mineral to aluminum. Reason for the high price is the difficulty to refine and purify, no rarity like most would assume.
Нужно обязательно обрабатывать с охлаждением,а по началу когда это корка от ковки по прочности как камень,нужно использовать самые прочные пластины,акогда идёт уже краснота стружки,говорит о том что пластины износились,нужно менять,у нас так на заводе произошло возгорание такой стружки титановой потушить её было уже невозможно,в итоге станок сгорел,даже станина расплавилась как от напалма, температура горения была очень высокая
Reminds me of the times when I was working on a Goratu GML 10 horizontal mill. That was a beast of machine, it had a 12000mm X axis travel limit. We basically machined only stainless steel parts. Man I hated that material.
Serious question. Why not do a single bandsaw cut at the bottom of the forge marks and then a single, shallow facing pass? Seems like it would be a lot more economical. I'm willing to bet those inserts are absurdly expensive. Bandsaw blades have got to be way cheaper.
There are special titanium saw blades with brazed-on hard metal cutting edges. These last much longer. And it would be also much cheeper. So same question for me. Why not use a bandsaw?
I think it's cracked like that because it wasn't cast to that shape, it may have been cast into a standard mold, then heated again and forged on a press with hydraulically powered dies. As the metal is formed, those surface cracks can develop, the trick is to ensure they aren't deep enough to intrude into the final required shape.
I always wonder what happens to these huge slabs of metal next? I mean, if it was this much of a production to just smooth an end flat, what sort of wizardry comes next to actually make things out of this hunk of adamantium?
There is so much to do. The forging is oversized so that the worst deep hammer mark, hole, pot, or inclusion is outside the part. Then you just twist the tool or the forging till all the extra falls away. Its fun to do and I love getting to work at my home shop even tho what I make is considerably smaller
I caught a machine on fire a couple times trying to machine titanium dry. There is enough aluminum in the 6al4v that coolant is very beneficial. I still machine it regularly and don't find it hard, just tough, sticky, and abrasive. However, forgings are a little different animal. Machined some titanium forgings that and been struck, were bent, so they were struck again. They sounded like glass when I banged them together. Titanium bar plays much nicer.
I know nothing about these processes but i cant stop watching them. Simply fascinating. Question, ive seen processes use cutting oil and was wondering why its not used on the initial rough cut? Edit: also, what becomes of the chips created? Do they still have industrial value?
I think the chips are just sold back to the supplier to be melted and re-used. I wouldn't know what else to do with bags and bags of titanium flakes.

Is it possible to reduce the rate of wear/failure of the inserts by using a lubricant or cutting fluid while machining? I don't know much at all about work like this, and really would like to know. It seems to me, as a layman, that having the insert get red hot like that can't be good for them. It doesn't seem like the chips are taking much or any of the heat with them, as you so often see when machining softer and less tough materials. Often the chips are glowing when they fly away, while the inserts seem not to heat up much at all, especially compared to this.
It depends on the the material the inserts made of. If it is Tungsten then yes cooling it with water is the way to go. But if the inserts are ceramic then cooling them does more harm than good. Ceramic is incredibly heat resistant so you ignore the heat build up. That heat resistans has a drawback that is if you cool it the sudden heat difference makes the inserts brittle und brake.

hmm, been way too long ago that I worked as a machinist. But I seem to remember that oil and water based coolant was not a good idea with titanium alloys. its been over 30 years so... (went into IT when it was still in the cowboy years back then)
The problem with running coolant on a heavy cut like this is that cooling the inserts too fast can crack them due to thermal stress. Compressed air is gentle enough, though, and helps a bit.
@Chad Guess I believe for the initial pass you need to get below the hard, uneven outer layer, so a slow, deep cut works best on the inserts. Taking a nice deep cut transfers most of the heat into the chip I believe.
Is that surface covering the oxide layer? Or is it covered in mud? Never worked with titanium before and never seen its corrosion. ...now 5mins in I see its the titanium's forge scale...weird lookin oxide layer 👍
That thing is half as wide as my car, but about as heavy when raw. The thing that always baffles me is the weight of these metals, even when they look light they are heavy, or look heavy and be light.
Used to work on a G&L Orion 1250 Premier making jet engine casings for Pratt and Whitney and Rolls Royce amongst other things. Fascinating work but the company didn’t pay worth a %#£€*^ do I had to move on. Kinda miss the work though.
I'd love to know that too! If I have to guess; the blocks of titanium comes in like this from the foundry and then the rough, unusable outside is milled off. Then it goes to another place where it will be sawed into "disks", and then sent off to machines that makes parts for jet engines, aircraft, satellites, robots, and such.
Just curious what gets made from that solid chunk of titanium. That looks like a metal you have to be very patient with! Cool video, thanks for sharing!
All the chips of cuted metal are re-melted an reused? or all is trash? because is a lot of meterial in lathe work with small pieces i know this doesn't matter but this is realy big
i feel liek even tho this does the job well if there was a high flow coolant nozzle it would make it so the tool tips dont heat up as much and it would save tyour parts a huge part of there life span

Titanium wasn't commonly used for very large pieces at that point unless I'm mistaken. But then if the firearm industry was having trouble as well that's probably not the reason unless they were making barrels for heavy artillery.

It would be a similar speed, the coolant takes the heat away and helps to extend tool life.
Cooling would destroy the turning plates. The hot spot is on the cutting edge
Always love the way titanium chips glow as they’re being cut
It gives me the creeps
They'll also combust, magnesium style, if they get too hot.
Very neat to watch, how many times during the roughing did you have to change the inserts? Charles
Great video, no babbling voice-overs like every other YT channel. Great stuff!

Why is no cooling fluid used when cutting this , does it cause the titanium to harden ? When you cut other metals cooling or cutting fluid is used ?
he turns it off when filming, he uses allot of coolant when cutting titanium to save the inserts.
What brand of shell mill is that?
what's the reason for the lack of coolant? can believe the amount of heat those bits must be tolerating

Why wasn't coolant used on the deep cut passes?
That's more treetrunk than round bar, but cool 😂

All i have to ask. How many inserts does this kind of job use.
How much mo.ey would you get for the scrap chips...or what would the price be for that huge peice.

Wonder what that block of titanium cost?
What would you use that big of a piece of stock for?

About how much would a chunk of titanium like this cost??? I could only imagine.

@@ashtonpadilla5269 I just saw, a titanium forging weighing several hundred pounds recently!! It was obviously a very basic about the size of a55 gallon drum as I recall!!!
Do you just listen for the inserts to wear?
Something tells me the 10pack of inserts for $26.28 on ebay matching that part# isn't the same quality of the ones you use.
How many cutting edges died during cutting?
How much for the chips? What do you do when them?
فوق العاده👏👏👏❤️❤️❤️
What is titanium made of?
Has Thaitanium anything to do with Chinesium?
The spindle is at 135rpm, what are the actual inserts at work such a larger dia than the spindle
what would this be used for?
At $130/kg those chips could easily be worth over a grand. Wow.
They don't hold the same value as chips
Titanium scrap is currently 25¢/lb.
What was all of that for what was it used for???
Почему вы обрабатываете титан без охлаждающей жидкости и почему такая высокая скорость резания при черновой обработке?
Is coolant not recommended for this
Are are the inverts? Carbide?
what part is this going to be?
I think i would be running the coolant on the spindle bearing housing...
I don't know a thing about titanium machining. I've (luckily) never had to work with it, as I mostly just stick to mild steel. Seems like a pain in the ass, but then again, I'm mostly used to using old machines with bends in the bed and no DROs...
That's the sound my bed makes 🤔
I need a 10 speed auto transmission made of that
why didnt you use a coolant or spray lube during the cut. the chips looked red when cutting, they can start a fire.
Интересно, это стружка до красна раскаляется или пластины?
Titanium is not good for carrying the heat away in the chips usually heat stays in the insert
Can someone say why there was no coolant liquid in this process?
I was wondering that myself.
Carbide runs well dry and hot
Certain grades of titanium can be adversely affected by some coolants especially if they contain chlorine.
Well that's a big ol' piece of titanium
Hi James, you need one more vertical lathe more (:
how much are those chips worth when its all said and done? im sure they can be recycled
What do you do with the chips?
Can it be gathered and melted
Sold to a scrap dealer. Currently at 25 cents a pound in NJ.
