I agree, a cutting …
I agree, a cutting tool is a cutting tool, a good machinist makes it work
The effective …
The effective differences between a boring bar and a regular OD turning insert are….uhh, nothing.
Hell I dont know …
I dont know why you all are so concerned about turning the OD with a boring bar I have used one as a substitute for a fly cutter in a pinch while milling on the lathe lol
What’s wrong with …
What’s wrong with ScubaSteveM45? So negative and arrogance?
Who said CNC had to be rapid? It is computer control regardless. If you are a home workshop, using stepper motor is the most ideal solutions!!
Anyway Payala, its good work. Which lathe model do you own? I’m thinking of retrofitting mine as well. Do you also have DRO fitted?
Did you replace leadscrew with ballscrews?
wow. lovin the …
wow. lovin the ghetto tooling. thats how we do it!
Thanks, it’s funny …
Thanks, it’s funny how everybody has noticed that I was using a boring bar. In a home workshop, sometimes, tools have to be used for tasks other than the ones they were designed for….
This video actually doesn’t do much justice to the whole system. Depth of cut is very shallow, since I was doing some tests… I should post a video with the machine doing some tough turning.
Thank you!
Nice video
Good …
Nice video
Good job with that boring-bar.
why are you using a …
why are you using a boring bar for that?
It is very nice …
It is very nice Ineed more information about cnc for my job, I am a techers. Thankyou.
be nice

I set a Hardinge GT SP fast and repeatable to a .0001″ we have a Haas as well not so quick but good for large stock
This is CNC, and …
This is CNC, and not NC. Check out CNC on wikipedia.
I have both a CNC lathe and mill which I have converted myself. The reason for it being so slow is the limitations of a homemade system. With servos you can get some preatty good rapids, but generally you will get more on a more professional machine.
And we do call it CNC in Denmark too (Jeg ved det sgu godt fordi jeg arbejder med disse maskinerne hver eneste dag). NC machines are a different thing.
Yeah mate i run a …
Yeah mate i run a okuma LB300M which is a sort of modern lathe and all u have to do is learn how to cover everything in the tool data and parameters. Programming is easy its the other stuff that can bring u undone if u dont know what your doing. Id say less than 2 months if u pay attention
i do like the …
i do like the boring bar. lol
The speed is so …
The speed is so slow and depth of cut is so shallow because it was my first test, and I didn´t want to push the limits. but i have achieved perhaps 2x-3x more speed and 5x bigger depth of cut.
You can call it …
You can call it whatever you want, it simply is a manual lathe with servo motors attached, and servo controllers powering the motors and receiving commands from a computer. If I had to, I would classify it as a home cnc lathe(it really is Numerically Controlled from a Computer).
The boring bar is just there becuse my normal turning inserts were unusable at the moment, and I wanted to make a test as soon as possible ( I was really excited to see it working, since I made it all miself).
its called a nc …
its called a nc lathe.its before the cnc came along thats why its slower.yea its ood they are using a boring bar for it.
Yeah and it looks …
Yeah and it looks like they’re using a boring bar for turning.
i heard it can be …
i heard it can be mastered in two months
pretty slow cnc …
pretty slow cnc machine
I`m taking a 5 …
I`m taking a 5 months CNC course I hope I learn this stuff I making it my career
Of course, when you …
Of course, when you turn in a manual lathe that’s the technique you have to use to compensate backlash. However, i have found that it is not easy to make the CAM program automatically generate toolpaths that make the tool advance always in the same direction (most important for X axis).
the missing …
the missing ballscrew isn´t that much of a problem if you make the program cut the same way all the time, this eliminates the backlash and the parts you turn will look as nice as parts from a “real” cnc lathe.
About the name i think it´s called a nc lathe, or at least we call it so here in Denmark.
True – main problem …
True – main problem is the missing ballscrew. At my workplace we have a “semi CNC”. No automatic tool change but CNC control.
