Great job.. I’ve only been doing CNC lathe work and programming for about 3 years, prior tool and die work, love watching your content… The feed and speeds content and DOC info along with the insert types is great information for newbies. Awesome job.
I'm just finishing up my first semester at my community college's machining course and it's fascinating to see blueprints come to life and actually be to understand it
Those are some fairly tight tolerances for such a large part. On something that size and more than likely full of stress, do you leave like 0.050 stock, let it cool, take a pass to sneak up on a one though tolerance? I would imagine 10 degrees and change 2 or 3 thou?
Looks like a good job. Keep the videos coming. Also please protect yourself with gloves when possible from exposure to metalworking fluids (coolant). It's documented that they cause kidney cancer at a higher than normal rates. I'm a 35 year machinist that has lost 1/2 a kidney to cancer. But I still love machine work.
I am also a Mechanical Turner and here in Brazil we have always been denied information about the dangers of coolants. Many friends have died without being aware of the dangers!

Problem of having gloves on is the risk of getting pulled into the lathe… I use a manual lathe many times and I don’t dare have anything on that can be caught up on and pulled into the lathe. The coolants may cause organ failure but having something on could cause parts being ripped off and or you getting pulled in a killed. Maybe can use some cheap latex or nitride gloves
Don't get me wrong, CNC milling is amazing work, but if I see these type of videos I miss the lathe. Especially the conventional lathe, so satisfying doing the manual labor. Thanks for sharing this!
Good work, and I encourage you to do more.. I am a metalworker like you, and not a few years ago, but I lost my job and became unemployed. I hope to find a place to work in this field
I would do it in the lathe but I'm the only guy running the big lathe and the vtl and we have more horizontal boring mill machines, so they help me out sometimes.
Thanks for the inspiration, I am trying to build my own large lathe because it seems the parts are way cheaper than the actual lathe and I don’t mind giving up some of my time to make something as useful as this
Find a good condition lathe with at least 250mm swing over cross-slide, at least 350 swing over the bed and ideally 1,5-2m between centers at the 5-10k price range, and just throw a Sinumerik kit on it. Fanuc might be more universal, but in terms of programming something in a pinch by hand, Sinumerik is miles ahead, albeit a bit intimidating in the first weeks or so. It totally compensated for that by allowing very advanced/complex machining/programming techniques to be easily implemented, using the tons of automatic functions of the controller (check out the use of NORM and KONTC/KONTT for example, or the very intuitive CIP arc programming).
I have found that making your own parts also gives you a better feeling of pride in your work and many times saves you more than money but usually you get a better part without the headache of dealing with what now seems outsourced support for ordering parts. I usually get some moron from India or the Philippines, I cannot stand talking to them as I do not trust them and can’t understand them, feel like I am going to be asked to buy extended car warranty insurance or scammed out of my money and or identity.
Holy Mazolla that's some serious metal moving right there. That new cutter is a monster. Always enjoy watching large chunks of metal being taught a lesson. Thanks again for posting.
CNC is old and cool to watch. Can be very close tolerance. But, I’m old school and I’d appreciate this a whole lot more if was done on a manual engine lathe.. that’s my world and that’s the way I still do it.
I have been doing mill most my life, I currently work in a 1 man shop with a small under powered lathe and CNC mill. So I do jobs like this on the mill. Unless there is a tight roundness call out, or it's too long , I will do it on the CNC mill regardless. I think it's just so much more efficient, regardless of my confert level to mill vs lathe. Am I correct?
Hola Chris,podrias hacer una comparativa de tiempos aproximada de la misma pza en un torno convencional???para conocer la diferencia de tiempos entre tú cnc y un convencional,saludos desde AGUASCALIENTES MEXICO
Something like this I can probably rough out 2~3 pieces with one corner. It depends on the type of material, size and how hard you want to push your machine.
there is really a lot of power at play on the larger diameters...limited area to clamp with manual chuck .. + heat in the workpiece ,, hydraulic chuck is better but also bad without pressure .. I have seen people turn off the machine and the workpiece falls out. .Normally there is an accumulator ball to keep the pressure up,, but it is dangerous with large workpieces if the hydraulic pressure drops what I wanted to say was manual chucks you can better feel how hard you are clamping contra hydrarlik which can clamp insanely hard and continue to clamp even if the workpiece gets very hot,,, I always always tighten 2-3 times when I rough turn when it's internal clamping so it doesn't come loose
Hello Chris! Can you please tell me how much material allowance do you allow for finishing on 5.25" and 12" diameters? 2:21 - 110% main drive load, right? Does it ruin the main drive?
I usually leave about 0.050" per side, but I always take two finishing cuts. Most of my work is one-offs so there isn't much room for error. I'm trying to keep the load meter around 100% when roughing and I haven't had any problems.
Who needs extreme sports when you have a couple dozen tonne metres squared per second spinning within centimetres of your face? Great looking part too.
We do get metric drawings but we only work in Imperial. All of our machines are set up for inches and all of our measuring tools are in inches. I was born and raised in Poland and I went to trade school with all metric machines, so it doesn't really make any difference to me, but US likes their INCHES.
Nice chips!! Great work by the looks of it, could be wayyy out though 😬😬 like my jobs!! What speed was you going to do internal bore? I'm back doing this again been out doing cars for 5 years. Fancy a change. What speeds and feeds are you boring at? I'm only doing 250mm bore depth, 45mm to 45.025mm hole diameter top size only.. I was struggling with chattering and vibration a high pitch wine too.. I've stopped noise and most of vibration.. running at 32sfm and feed is 0.13 fpr. Boring bar is dcmt .8 rad 28mm 1 tip tool.. 42mm drill (only good Sharpe one close to size) fucking hell I really chat some bollocks!! 😮
0:12 - Did you press that in and then center drill? 0:50 - Clean fingernails, sign of a machinist! 0:59 - One OD at +/- .0005" from the median; they don't know from Chris! 2:22 - I don't know from CNC (we pay for it), but looking at the screen gives me some idea what our suppliers see, and how to respond to questions. 6:12 - Leave no chatter. 6:53 - That's the +/- .001" dim; got an ax? I can do that. 10:46 - OK, but 11:07 - very nice finish. 11:26 - Most all of us here could easily deliver +/- .0025" from the median; you can do that in your sleep
@@ChrisMaj I understand 😊 I've seen alotta good return about that kennametal insert you guys have been using, top notch I must say, coming from a everyday production employee
@@ChrisMajHow do you get the same diameter on a different feed rate though? Did you have to program any tiny step on it or something or was it done in two passes?

This was the first time I've seen a diamond shaped insert. Certainly gives a nice finish.

Some of those tolerances look pretty fine for a hefty part, how do you deal with thermal expansion before finishing pass?
Those are some fairly tight tolerances for such a large part. On something that size and more than likely full of stress, do you leave like 0.050 stock, let it cool, take a pass to sneak up on a one though tolerance? I would imagine 10 degrees and change 2 or 3 thou?

That's so hot. The chips are lovely, both sound and appearance
I could definitely do with one of these tools for hard forgings!
I love tangential inserts, they last forever with 8 useable cutting edges.
Up until you get a bad one and it shatters for no reason lmao
Nice chip control Chris.
The work is interesting, especially when it is finished well.. but make sure to protect yourself as much as possible
So this guy uses tools the size of my lathe bed with bolts to hold them the size of my spindle.
And prolly removes more metal before 1st break than your lathe weighs lol... just learning coding and cnc lathes at my job
Great national work 💪
very good job chris maj
Nice Job 👍👍

Working really really well done, I'm curious. How many pieces you can make before changing insert corner??
Something like this I can probably rough out 2~3 pieces with one corner. It depends on the type of material, size and how hard you want to push your machine.

Not the most decimal places I've seen on your jobs, but challenging enough.
Not many tight tolerances, but a lot of chips though.
Another part that would have been better made out of a forging. Depends on stress to which it's subjected to. Also, expensive that way.
Well, maybe, but not if customer needs his part yesterday. Forgings are expensive and time is money.
How did you check to make sure you have the 8 finish?
