Very nice, thanks for sharing! Personally, I would have flipped the order of operations, and held the part for the 2nd op using an expanding mandrel inside the ID bore. That would have offered several advantages: (a) No custom workholding required. (b) Expanding mandrels are rotationally symmetrical, so no need to adjust the C axis offset every time that you change the subspindle chuck. (c) The entire OD would be machinable during the 2nd op, which would make achieving high cosmetics easier (no workholding marks).
What is runout to side1? Look like it must be big... even if on first part it ok, on others in can be big difference, according to dimensions from side1. During video i waited runuot check and modification of flat jaw to make it ajustable....
Wow nice solution!!! Im not a lathe guy. But What If you approached the part from the opposite side. The (flange side) first. And Made a nice fixture with 2 Precision guide pins to get the rotational accuracy perfect. Then bolt the part to the fixture. In my mind this could be Done on both the sub spindle and the main spindle as a op2! Well there are so many ways to skin a cat i guess🙂🙂 As a few people in the office know. I am a huge fan! Cool Idea on the fixturing guys! //crazy Swedish guy😛
We've made odd shapes with pie jaws all the time for our supspindle. All about jaw orientation. Tyson did a great job explaining this!!! If your boss ever let's you try it, I say go for it!! It will save you money on extra tooling and setups.
Since all 3 of them were likely printed at the same time any amount off they may be from 3D printing inaccuracies will be the same across all 3 of them so I think it makes sense
how do you know it was perfectly? I would like to see an indicator on the part to see what the runnout was. Or they did not test the runnout or it was not good enough to show. I guess the last.
I own a precision grinding company, with 30 employes and we could have ground that radius, on the "off the shelf" jaws in 20 minutes with a surface finish of 16 micro
Clever work holding solution for a one off part (indicator measurement when lining it up would have been nice to see) but for series production the work holding and therefore machining process might need to be changed
As a retired tool and die maker of 54 years you should try to program that manually then I would call you a real machinist. I’ve been programming multi axis machines before you were born. That said the solid works does make it easier and faster. Nice job
The spherical ones yes. But on a lathe you’d have to make all 3 of them spherical. I suppose you could just do that then remove the one and throw it out. Put a new flat one that you mill flat perfectly to spec and get that concentricity requirement

Good & exlent working bro
I am totally surprised Kennametal allowed you to get a capto spindle and not one of their garbage proprietary km spindles
100 points for overcomplicating it.
Mr Gilroy does machine automatically compensate for the insert wear as it is cutting just curious love your videos be safe and have a great day Sam

Real good.Great video.I cant wait to get my hand on a turn/ milling cnc.

Great job
No juicy chamfers? Those edges look burrrrry

I'm impressed those jaws got the centre aligned perfectly.

Tyson laying it down! Solid knowledge of solid models, jaws, and turning a masterpiece!
1.5 inch groove lock or camlock for hookup ? Opposite of flange
Perfection!
Tyson == OG. always love your videos. Love the way you teach, thank you
Hey, I'm building a America business I need a cad guy for the grant would you take the position
That chuck must have a huge clamping range
Solving problems. Looking forward to your next video Tyson 🔥

Odd that the chuck has drive keys instead of serations?
Good work Tyson. I like the creative work holding with the round printed jaws and 1 flat jaw👏
great use case for 3d printing. Cool looking part
Great technique! Tyson’s videos are the best!!
Beautiful part Tyson! I am glad the jaws helped with your second op. Great video!
i’ll never be a machinist, but i can sure experience the joy of it from this channel.
Picking your nose is similar to machining
Damn brother you must be a well seasoned machinist 😂😂👍👍
@ i’ll… uh… keep that in mind.
the slow feed at 1200 rpm might be a bit hard to replicate though.
Brother, aint nothing enjoyable about it
That’s a nifty work holding solution Tyson! Nice job!
Great video, Tyson!
Use metric
Wouldn't it have been smarter to make the flange side of the part first, and just use the holes in the flange to bolt it to a chuck or table?
Why haven't reversed the last operation as first on dial pins and the most of the openings to be for holding the part with screw nuts

Yeah, with plastic jaws don't use to high RPM and tool cut pressure.
Could you just machine a set of soft laws?
The spherical ones yes. But on a lathe you’d have to make all 3 of them spherical. I suppose you could just do that then remove the one and throw it out. Put a new flat one that you mill flat perfectly to spec and get that concentricity requirement
