@@ChrisMaj don't get me wrong, I'm glad he is learning new stuff like heat treating and what not but sometimes you wanna sit down and watch some heavy cuts being taken
Very true ... when he worked on the big stuff it was very cool. But one day I swear he just spray canned a cabinet one day for one of his videos. That’s the day i realize it was time to move on.
you are a real inspiration. I have a small lathe, and watching you go at it makes me want to create something. I learn a lot watching your vids. I did CNC (wood router) for 23 years, running a cnc lathe has always been my dream. bravo.
Spent my career looking to make smaller and smaller more precise parts, ended up as a grinder hand making laminate and connector mold inserts. A part 1/3rd the size of a pencil would have been considered huge, and + -.0002 would have been considered an open tolerance. I'll be seeing this in my nightmares tonight.
@@heir6289 surface speed could be increased as its on the low side if its mild steel, change roughing insert for an edge saver, which will allow to increase depth of cut
@@andrewtaylor5962 Is it mild steel? Can you tell the surface speed from this video? I admit I have no idea what an edge saver is but it seems to me they have the material chipping nicely for each cut depth we see here. The main roughing uses most of the insert cutting edge so if there are two roughing passes you would need to double this depth in order to get your 50% reduction in time. I'd say these people know their job very well. I'd still be interested in knowing what an edge saver is though - maybe it's called something else here (Australia).
@@andrewtaylor5962 It's 4150 Q&T at around 320 Brinell. You do realize this thing weighs 3000 lbs (1360 kg) and I don't know about you, but at this weight I like to keep my rpms on the lower end and this lathe only has 600 rpm max, so you can't really go crazy. The DOC is 0.350" (8.89mm) FEED 0.020 IPR (0.508 mm/rev). You said you could cut about 50% man, I'm listening.
Awesome job, we use to make printers rollers very often, most of them with a rubber layer on the surface, but instead of using a solid steel bar we use a hollow bar.
I'm still trying to figure out how it's turning so true with pre-drilled center holes. At first I thought you'd run it thru the spindle to finish the opposite end but was surprised to see it finished all that way opposite of the chuck, especially without a steady rest. Impressive stuff dude.
I don’t know diddly about this, but it looks like those spindles are too small for that piece. Great video!!!! I wonder why it’s satisfying to watch a piece of rusty metal being turned into a shiny piece of metal being made to do stuff.
@@Thebalkan84 I don't know what kind of lathe you have, but sometimes just getting a different live center can help a lot. I really like Skoda live centers, they worked better for me than the Royal or Riten live centers.
I guess you turn over alot of these to have it programmed for cnc.. im just a hobbiest with asian manual machines. Dont make much more than occasional beer money.. would like to learn how to program though
How did yo7u put the center hole in the shaft? Did you do it by hand or on a horizontal boring mill? Great videos by the way. Just liked and subscribed.
Chris everything looked ok until I saw you facing the end using a triangular insert creating birds nest.I would normally machine from small end to big end and finish at the chamfer since the barrel was already finished unless you have a valid reason.Otherwise a nice job.
If you're running NC with a manual toolpost, don't you have to touch the tool on the post? How can you take NC to a finish dimension with a tool that hasn't made a cut yet?
@@ChrisMaj awesome work man. I've never done big work like that, almost a foreign world. So, you take the stock to the boring mill, face it off there and put the center in. Then turn what you can, then back to the boring mill for the bolt holes on the recessed face?
@@ChrisMaj lol thanks for reply . is it even possible to fininsh one part with one insert ? What precision is needed for such parts ?( tolerances ). how u know that part is well centered in that chuck? looks like fun job :)
It's not clear that's actually a CNC lathe / turning center. Pretty doubtful. If it is, then it's a fabuous waste of CNC because the same job could be done so easily with a manual machine. There's no good justification for using CNC for simple stuff that can be so easily jigged and done by hand.
0:35, 3:23 if that's not clear I don't think I want to argue with you. By the way, we only have couple manual machines, large lathe and a vtl. So I'm using what I got.
@@ChrisMaj I see nothing telling at 0:35. I see a big DRO at 3:23. I see a giant manual lathe that may or may not have been "CNCized" but that (if it has been) could easily be operated manually, as it was designed to be operated when it was built. Me, I believe I'd decommission the CNCization if it's been done and set it up to use jigs instead. It's just so much simpler and doing so costs nothing. But that's me. Maybe you have something more profitable to do with your time.

Awesome job, we use to make printers rollers very often, most of them with a rubber layer on the surface, but instead of using a solid steel bar we use a hollow bar.
Tube
I used to make them, they were known as rolls.
We swapped to plugging and machining pipes too, way lighter and cost effective.
you have got to respect the bearings in those tailstocks, all that load on the tiny little live centre cantilevered out from the base.
Yeah, we just recently replaced the bearings first time in like 15 years.
darn straight billits for forging
I'm still trying to figure out how it's turning so true with pre-drilled center holes. At first I thought you'd run it thru the spindle to finish the opposite end but was surprised to see it finished all that way opposite of the chuck, especially without a steady rest. Impressive stuff dude.
You can't see it on a video, but I did flipped that part four times and turning between two centers also helps.
I don’t know diddly about this, but it looks like those spindles are too small for that piece.
Great video!!!! I wonder why it’s satisfying to watch a piece of rusty metal being turned into a shiny piece of metal being made to do stuff.

They look like the rollers I made for the steel rolling mills in Cleveland, Ohio.
I know they are used in steel rolling mills, but where they go I have no idea.
How did yo7u put the center hole in the shaft? Did you do it by hand or on a horizontal boring mill? Great videos by the way. Just liked and subscribed.
All done on a horizontal boring mill.
Could you expect any runout from not supporting it in the middle?
Chik!!!!!!!
You can show how you make the center mark before turning
Was there an indicator used to help mount the work piece in the chuck??? Always like to see that.
Yeah that's the first thing I do, check the runout before I do anything else.
Chris everything looked ok until I saw you facing the end using a triangular insert creating birds nest.I would normally machine from small end to big end and finish at the chamfer since the barrel was already finished unless you have a valid reason.Otherwise a nice job.
I do it both ways, but you do get better finish going backwards (large diameter to small diameter)

High RPM
Slow feedrate

Would it be more precision, should you turn between center ( not using a chuck)....I am just an armature.
There is a center in the spindle, but when you take big cuts you have to have a good grip on your part.

This is very easy job.
Where does it say that it's complicated?
