Nice proof of performance in using 3d printing in parallel at work. It speeds things up! Even if you were to make a delrin test part, 3d printing makes more sense for rapid prototyping and less waste of expensive materials, especially in a home shop. No one wants to buy a do-over slug of steel. 3d printing saves you from kicking yourself in the coin purse. Appreciate the work you do for the community in sharing your knowledge, thanks again.
it's nice to see some actual machining. It seems like most machining on YT is all light cuts. Babying their machines. Turning like this seems like you actually want to make money. While I don't recommend turning like Titan, using your machine and your inserts to make you money is the only way to go.

Hello. I have 5 years of experience on 2 axis CNC lathe, I usually do piece and small series production, choosing tools, inserts, setting up the machine, writing program, making the parts according to documentation, occasionally steel (from mild to about slightly hardened to 35HRC), most often stainless from martensitic, 1.4305, 1.4301, 1.4404 to 1.4571 (316 with bit of titanium I believe), 1.4462 and rarely various alloys like inconel, arcap, hastelloy and a lot of aluminum-based soft alloys. I machine from palm-sized parts up to 45kg stainless chambers and 120kg 0.75m shafts. I am very interested in this trade, sadly there are very few communicative and helpful people with dozens of years of experience who could I ask and they would answer my questions correctly. After watching this video, my views on machining are very confused. I usually run parts in claw-jaws, on big parts I set hydraulic chuck on max. 2MPa (99kN) so it doesn't just slip or fly away. The turret lathe (26kW spindle probably) usually allows me 4.5mm D.O.C in very soft aluminum-based materials, 3.5 in softer steels, 2.5 in medium materials and 1-2 in very hard materials. The problem doesn't seems to be stalling of the engine or tearing the part out of the chuck but rather low rigidity of the machine. Anyway I thought that the part is forced "against the cutting force of the tool" or out of axis, so it just tears itself out of jaw opposite to the tool and flies away - that's why you need centerdrilled the big chunk because the force away from the chuck multiplies the force perpendicular to the axis by the lenght of lever, so you need live center to "hold the force perpendicular to the axis by centerdrilled area" and to push the part back to the chuck. For example if you try to turn small rod at the end of the machine, it also just bends and starts flapping around (hopefully not hitting you). Now imagine this force but on the bit part that doesn't bend but just gets pulled out of jaws. Then how is it possible that you: -don't have center drill, just "push" the part into the axis, so it won't oppose any force perpendicular to the axis multiplied by the lever -hold the part in manual chuck that you tighten "by hand" -hold the about 400mm long part just by about 40mm long jaws without any "claws" that "bite" into the material And take 12mm D.O.C with atleast 0.3-0.4mm/rev which equals to force of like 4-5 small cars pushing on the part and the part doesn't just get torn out of the chuck and fly away..? I once came with hangover to work, forgot to change pressure on the chuck, left it about 0.7MPa which is about 30kN static force, took 3mm D.O.C, 0.3mm/rev into 304 stainless steel and the part just flied away. How.. how is this possible..? Where is the trick..? Several times, I tried searching for some machinist technology handbooks on how to calculate force of the chuck and compare it to the force of machining, the DOC, feed, cutting speed, distance from the chuck, etc. and calculate if the part is safe to machine or not, but there is nothing like this. Could some guy who works in this trade explain this to me or direct me the right way, please..?
I don’t know much about CNC so I don’t know where I can provide insight but usually when I do heavy turning, I like to make sure I have tailstock support so maybe that would help you. I’m not really sure what’s going wrong on your end. Also the rigidity of the machine I’m using far exceeds most CNC machines unless they’re really large ones so that could just be the issue there. The beauty of having a computer run the program is you can take lighter cuts and walk away so efficiency is a little less important.
@@VanoverMachineAndRepair Yes, I fully understand that you have machine for heavy turning and its rigidity is far superior to mine, especially due to the turret. The CNC and classical machine differs only in that on CNC machine, you have computer that controls servomotors which move the toolbed/turret for you and instead of having trapezoidal screw they have ball screw so the movement is more accurate as you don't measure the workpiece after every pass. Otherwise the principle is the same. My question is more general machining related - how do you calculate the clamping force and force of tailstock so you can be sure the workpiece just doesn't fly away and kill you? We had some basic calculations about frictional force between the workpiece and jaws must be greater than cutting force but nothing really specific. Or do you just tighten the chuck and hope something doesn't fuck up and kill you..?
@@VanoverMachineAndRepair So do I, I just don't tighten it by force but increase pressure on the hydraulic chuck. I was just asking if there is any better option than "let's just try it, either it flies away, destroys the machine and kills me or it will work".
Generally speaking for roughing in steel I like to run it at around 180M/min at .3-.4mm/rev and about 4-6mm on the radius. If you're not looking for a decent surface, give her some feed, makes the chip really small and easy to work with.
His insert would last longer if he was to use coolant yes (generally speaking), does he "need" coolant? absolutely not. You can generally tell if your speeds and feeds are wrong by the heat generation of the part and by the chips, i learned if your chips turn blue and the part isn't getting that hot your speeds/feeds are right. And generally speaking the faster you can remove the material the less heat you generate (because it is in the chips). !!!And i have to note here that some carbide insert manufacturers recommend using NO coolant because of the thermal shock (rapid cooling and heating), which could cause the insert to crack on you.!!! Yea he is tacking big healthy cuts not like other machine channels who baby their machines..
Thanks guys I’ll get coolant on the lion. It def be nice for certain operations but for now no coolant. I wish I had it for drilling but od turning not as necessary.
I would have cut the piece first and then worked in the lathe, obtaining essentially maximum rigidity and concentricity, without tail support. I also would have bored everything in one piece, from the back side. The additional dial-in at the end for chamfers would not require maximum accuracy. And actually could be done through hole.
After you teach it to sing Kyle you'll then need to teach them dance! Good going Kyle on making some nice chips. P.S. You want to see some chips fly, checkout HAL engineering. He's in Australia and he's some monster bars.

@ramentaryramblings dude You have no idea.... I work at a plant where they use Metric and imperial and caveman and some other stuff I've never seen all toghether on a operating nuclear plant. Pressures flow rate temperature everything mixed and matched all over the show.
You seriously don't realize that almost every manufactured item US or not is usually a combination of both? Good Lord I'm 63 and we were converting to metric when I was in my teens. If manufacturing for a world market metric is required. Get a metric ruler and learn how to count to ten and you'll be good big guy.
@@matthewmoilanen787 lmao yeah sure, I work in industry and still haven't converted with zero talks of it. we're not going metric any time soon and you sure as shit don't need to know it to make global shit. never in a million years

Take that chuck key out! I know apprentices that were sacked for leaving the chuck key in a lathe chuck, I've also seen one embedded in a stud wall from someone turning the lathe on with the chuck key still in the chuck.
Mike the customer is yet to be determined. He needed the part to make an incomplete bucket complete to sell. My point there was it is unlikely that he will care about the looks so it will most likely sit outside and rust which is fine as it is just heavy equipment and is unpainted. Who ever buys the bucket won’t care.
you should run for president with all that useless word salad, or do you get more money if you say the same thing 25 times.... could have cut this down to a short..

lol hilarious
And it was at this moment that mini lathes didn't seem so cool anymore. That American is a BEAST. Amazing work.
you got that right
Unless Quinn is using the mini lathe, it’s indeed hard for them to be cool
@@jamesriordan3494 good point.....
Thanks. I watch Quinn, and artisan makes. I like big stuff but small stuff can be cool too. I like Stephan from Europe too. Just to name a few.

Morning Kyle,
Great video producing a part with some heavy material removal while preserving material needed for a second project.
Thanks for sharing.
Deletes wasteful chucking allowance.
Thanks appreciate it
Nicely behaved chips, alway a plus.
Good call on large billet, versus wasting chucking allowance.

26:00 would it be a good idea to hit it with a neutral insert to make a groove for the blade to follow?
Maybe. My steady rest wasn’t that big though so that’s why I didn’t use it.
You should always remove the chuck key, can be dangerous if you start the lathe

@@adamsevcik7708 in manual machining you don’t calculate clamping force. You just tighten it by feel.
