Gotta appreciate how detailed yet digestible Tyson explains everything 💪
I'm not a machinist but love these videos. Production level and information is awesome!
❤️❤️❤️❤️❤️
I could watch this stuff all day. I’ve never been addicted to anything but I finally understand how it feels
The hell is the video finishing the part?? Blue ballin us man?? One of the best videos I’ve seen on the channel and I can’t find one where you finish the part??
Thanks for explaining how the center works. Charles
Pretty sweet center! I've never used a spring loaded one.
Not sure how complicated this is. 17-4 machines like a dream,could do this job in a manual lathe and mill in about 6 hours max
This guy does a great job for a CNC But you're right way faster manually. Because of the large shoulder. I would have run the threading tool upside down-and-out. Another Ted bit. take a kiss on the OD easier to indicate in
Yep I agree . I would have that part resting on the inspection table while they were still programing that $200,00 machine. .. At least the first one.
I think I would have pre opped the back side and bored soft jaws, and then did the threads and the OD in one op. Regardless, I definitely would have done the threads and OD in the same operation. I’d also program the OD as a taper with some comp in the tool. Then adjust the comp and taper and bring it right on with a second finish pass.
Threads that far out without a steady would want to vibrate and chatter like fuck. At least on my lathe (11tonne semi CNC Broadbent).
Agree with the prepping operation and using softjaws. Because that rough bar end could be the same center with a bit of mellot help but not sure how cylindric the rest of the already turned bit with it
sorry didnt see your reply till I posted. Your 100% correct. You would chuck this up drill hole, put small chamf. run the center in and run all operations.
I remember, back in the day, programming in BASIC on my Commodore 64 at night for fun. Then cutting threads on an old manual engine lathe at my day job. . and the boss telling me we don't need fancy machines , just good machinist.
I used to use the small amount of linear movement from the jaws clamping to set the live center pressure. put the live center in position and then pull the part out and set it on the center, then close the jaws. Eliminates the indicator and the possibility of operator error. I don't think it'd work well with the spring center though.
Love this channel and awesome explanation! I just waiting for Titans to go in sheet metal, that would be great
Nice series Tyson. Thank you.
Centers are drilled with a turning spindle ( or part ). Drilling centers with a live tool means the drilled hole is not concentric to the rest of the turning job.
I agree, with not using a live tool for the center and .002" TIR isn't bad, but if it's not right it's wrong...
Well if your live tool with your center in is clocked perfectly true as well you'd be ok but I agree with its better to use the main spindle in general. He never shows him clocking his live center which is kinda suss. This part of the job can be make or break so it's important to talk about.
@@cygnascent He clocked the live center in the previous video, it doesn't show it for very long but it does show it.
Just Curious, did you run a de-burring pass on the threads? After running the threading tool we used to come back and run the turning tool again along the O.D of the thread using the same tool path but faster feed rate and then come back in with one more pass of the threading tool to remove burrs, which would give us a much cleaner thread.
love your videos Tyson and the way you explain things makes sense to me. what coolant are you guys using
Hey bro, I wanna ask this;
1. Why would you drill then center drill to make the chamfer and not center drill then drill?
2. Why did you thread that shaft before turning, I think if those threads are to be mated to another part that requires concentricity of them two those threads will make it out of concentricity?
3. That hole you drill I don't trust to be concentric with the entire length of the shaft unless it has other processes on it?
Other wise great video, thank you.
1 idk maybe to not brake the center drill by going in to deep, some drills don't need a center drill
2 probably because he wouldn't have clearance to thread afterwards, he is using the turet to hold the center
3 because he indicated the hole it should be fine , I guess they have good machines.
Where I work someone hit the turet so bad that it became out of center 0.4 mm or so
Carbide drills dont need a pilot hole.
@@apostolrobert5810 1✓
2? He still would go ahead and turn while holding with center, though I checked the kind of threading he has. Cool
3. May be you can say the material provider checks the trueness of the product for such consumers when needed, other wise mmmmmh nay.
@@johansrensen3291 for carbide I believe they are cool, so that part dropped if so. Thank you.
1. ....solid carbide drills do NOT like zu open holes.... i would even turn the chamfer or mill it instead of using a centerdrill
2. thread turning with overhang like this, even with livecenter, will result in shatter in the cut....at least at the finishing cut
3. it is true becaus he has hammered his part to run true to the turning center
i would even recommend to get ur part running true to center an THEN set ur G54 ...
Awesome! O love cnc latch content.
No point in knocking out the runout when you're just gonna use a steady rest. It will just throw it out if the steady isn't on center.
I own a shop this is not how I would advise making this part. But it does work for a one off PC. In production we would prep the backside, fac and turn slugs and use soft jaws to load these blanks and do this all in one setup.
CNC brilliant, but just gose to show how skilled the engineers and machinist at the beginning of the industrial revolution turned out all the parts for industry on line lathes, milling machine, drill press ect free hand. I used to cut threads on lathes freehand .005 in .0025 lead repeat, not easy but enjoyable at the time.
Am I missing something or what makes this part extremely complicated?
Should have said "extremely basic" nothing complicated about this part
BOOM!
For real this isn't even close to complicated
Havent checked the drawing.
But i would stick the part out completely already (second part here) with schunk teeth jaws on max pressure , cut the face gently small steps, drill with it a centerdrill with the C axis on (drill turning). Put the center in the hole, and do all the cutting.
Then turn around and do the other side with cut cut soft material jaws.
This is possible on my machine, turret cnc lathe.
Maybe not on this one.
Amazing thanks for explaining everything!!
CNMG432 is life.
why not machine it sticking out the whole length then, face, centre and drill, load the tailstock, then turn and thread the whole shaft in one opp without the need for manual loading and clocking?
I run a machine making shafts about 350mm long with around 200mm sticking out and they work greath like that all day. You can even rough turn, remove the tailstock and recentre if needed for runout, then reload the tailstock and finish turn and thread.
Interesting centre though. We use a centre without the spring and the machine is capable of pushing the centre in with a set force
Glad someone said it.
What would you like for percentage of tool/tip wear in production run condition suit this application
Good good Tyson!
Upload the continuation of the machining
Are depth of cuts listed per side or material off diameter?
Always curious about the rubber mallet hitting to get the last little bit of tolerance in place. Does it really stay in position once you turn the machine on? Surely tiny knocks on the material don't compare to all the forces involved once it starts spinning, right?
You have it slightly tightened when hitting it with the hammer and then you fully tighten it when its true?
Where do you find this live center tool?
Is that a Ford electric motor axle?
Did everyone get all that?
A Bolton lathe and a Enco milling will do it too... 😁
No blunt start or stop on the thread. Beginner 😂😂😂👍🏼
Can you clarify the drill feed. Wouldn't both cutting edges on a drill see the same amount of material? You said .008/rev or .004/tooth.
There is 2 cutting edge on a drill.
Both flutes get .004, those add up to the drill being .008
I understand what you mean but 0.008 is simply the feed for each single rotation. If you think about it, if there are 2 flutes and the tool progressed 0.008" each rev, then each cutting edge/flute will have to take equal parts of that 0.008" aka 0.004".
And to your point they certainly do see the same amount of material
👍👍👍
Next time you get an smx, see if they'll put a komet u axis on it
I wanna see big parts that are so big that they go from the floor all the way to the roof or mill 12 000 mm long thin plate from super duplex without bending it
Looks good and all but NEVER use center drill as a driving tool in center, x axis is never 100% true to centerline, use spindle to do the work and get rid of that variable.
it's true if you true it up properly, which is easy when you have Y axis on the turret
Whatever he is doing in the video, center hole will be concenteic to the thread, it wouldn't be whith my suggestion.
My thought exactly.
this part would be so much easier with a steady rest
I was thinking the same thing.
No thread clipping…..?
why hold run-out to .002? why would you not want that as perfect as you can? say .0002?
What makes this extremely complicated?
Basic stuff, idk..
It’s a video in a series of video on this part. .0001 on the long shaft and the parts hanging way out etc… and it’s 17-4. Butter for some but most have never done anything close.
@@TITANSofCNC When I think of an "Extremely Complicate 9 axis part" I think of something that has multiple angular and non angular work faces and features that come from a single datum point. All of which is tight tolerance with dozens of tools. Not trying to be insulting but it seems click bait"ish" like some of your other videos.
Omg I thought the exact same thing. On a MANUAL machine a MACHINIST could do this in less than a day. Including the grinding. And a quarter of the price probably. Hilarious.
Working with the imperial measure system.
So weird, looks like your spindle direction is wrong and your cutting with the back side of the insert when you were threading, judging from the direction of the coolant spray and chip evacuation. Also the look of the rotation of the chuck .
Kennametal makes a threading insert that finishes the major diameter of the thread that looks almost identical to the insert you used, saving the need for the finish pass before threading.
Nice Am in sir lanka ❤️
Have fun with sir Lanka :)
Well, are you a machinist?
@@arkadas3797 yes 🤗
@@arkadas3797 you are
@@chalanahettiarachchi yeap man
Зачем выставлять торцовое биение? Если все равно задним центром идёт поджим.
ハンマーで引っ叩かなくてもチャック掴みを少なくすればいいんだぜ🤣🤗
I dont see the 9 axis but then again I dont work with these machines :)
: D : D : D 👍👍👍
Interapid DTI’s are the best not Mitutoyo
What the hell is thst kennametal?!
I don't see it. What is so extremely complicated on this part? It's a screw. I program every day more difficult contours on my 3 axis lathe (also a puma) with out any CAM Software in two steps.
You lost me at Hi.
This is a very bad commercial for a mitutoyo caliper.
Metric!!! Metric!!!!!!!!!!
Режимы резания просто смехотворны. И технология не правильная.
Lol what's with these titles?
Nothing about this part is even slightly complicated. Like 90% of it can be done in two canned cycles, ~10 lines of code or so..
Tolerances might be tight, but that doesn't make the part itself complex
.0001 on the long shaft and the parts hanging way out etc… and it’s 17-4. Butter for some but most have never done anything close.
@@TITANSofCNC I believe you in that it can still be a really difficult part to machine, but from the videos it doesn't look complicated at all.
Your octopus, or that huge titanium part you did in that huge horizontal a while back, now those are complicated.
