Excellent, love the chuck creating a vacuum sucking the smoke away early in the video. Thanks for sharing.

[@neilrobinson1956]

Real old school centre lathe work with the added extra of NC, takes me back to my apprenticeship days at ICI, and you never forget how easy it looks, but in practice...well that's another story. Thanks for sharing a great piece of work.

Perfecto amigo Chris Saludos que tengas un excelente fin de semana 👍👍

[@HybridiHippo]

That was good idea to come out off the chuck with vnmg ships were nice that way. Nice flange it came out.

[@bones357]

That was a lot of material to remove, and as usual the surface finish was excellent, even on that bore!👊👍

Yeap whole 535 lbs went in the bucket.

@@ChrisMaj Have you ever thought about recording your CNC machine's input screen while you program a part? That would help me alot and maybe other inexperienced machinists! Kind regards

@@mjmj5224 the thing is that lots of my programming is done in FANUC manual guide.

Your hands are good for measuring and good tool selection

[@Michaelsloncehammr]

I would have went with a 55 degree instead of the 35 degree finisher, but I don’t what’s available. Also looks like a custom made boring bar. 🔮🪄

[@douglaspierce7031]

Have you ever tried wiper inserts for finish turning? You can feed twice as fast and achieve the same finish.

[@danielkalinowski5994]

theyre good if you dont have to turn into shoulders. usually id use sandvik mild steel inserts and use higher surface speed. en24t id use 300sur with a finish depth cut of 0.3mm. bit in mind, the longer the part leave on a little more material with slower sur or carbide / dampened bore bars

[@userwl2850]

At 2.43 I've seen these slip off with the G-clamp not tight enough and people underestimate the weight. Did you mean 5 thou tolerance or was it really half thou . That is really honed tolerance. That lathe is a beauty. Nice video again. 👍

[@ChrisMaj]

I do tighten these fuckers hard and there was only 215 lbs (97kg) left, not that heavy. I think 0.001" tolerances it's pretty standard .i.imgur.com/xucPHHS.jpg

Hey Chis how do you set you tool off sets on that lathe?

Take a test cut, measure it, enter into the tool offset.

How is the variable spindle speed controlled?

[@ChrisMaj]

It's controlled by G-code (G96 constant surface speed)

[@adilsongia]

Como faço pra ir trabalhar aí? 😁😁😁

[@pcbondart]

bore tolerance half a thou . . . at what temperature!?! That's a BIG part!

[@ChrisMaj]

+/- 0.0005 at about 70 degrees Fahrenheit

[@Mister_H.]

Coolant merely a suggestion 😂

[@Barkeraquaticss]

Turned the coolant off momentarily so that we as viewers could actually see the cut. You thought you were being clever with your comment, but it just shows that you are not.

[@Icutmetal]

Not always necessary; especially in something like 1045, but there will be a fair amount of heat buildup with that amount of stock being removed.

[@fraziercrawford]

I have a question about the final surface finish on the flange! Was it just as fine as in the bore/ on the OD? We're always having trouble with pressure marks from the jaws at work, and our solution has always been to switch to different, softer jaws for Finish OPs. But whitg such a big chuck as you use I can't imagine that's as feasible as with a HAAS's SL20 jaws. Do you used the same jaws through all OPs, and have a trick for keeping bite marks out of the flange? Or do you indeed switch jaws for the finishing op?

[@ChrisMaj]

The finish on the flange wasn't that critical and the jaws are smooth and they have a radius on them so they don't really leave any marks. On this chuck I can't switch to soft jaws so if I have to I'll use some aluminum/ brass shims to eliminate any marks.

[@user-dk8os5yw9p]

Мне одному интересно кто и как сделал радиус около 20мм?

[@kisspeteristvan]

around 200kilo material removed... how long did it take ?

[@ChrisMaj]

Yeah 240kg to be exact. Rough and finish about 9 hours not including rest time after rough turning.
