The whole time watching this, I could really only think of one thing.
That nub you get in the middle of every surface faced off, that's because your tool is below center...
Same.... I wanted to reach through the screen and adjust the tool post height so bad
In the interest of actually being constructive, instead of just pointing out issues, the technique for correcting this error is to measure the diameter of the nub.
Half of that thickness is the size of shim you need to slide underneath your tool in the toolpost, in the case your lathe's cross-slide doesn't have a built-in method to correct it.
I was thinking the same thing while watching lol
maybe he feels the finish is better having the tool bit slightly lower ?
Hello! Yes indeed the cutter is set below the center by 0.05 mm I do not see anything critical in it, worse if it will be above the center then the cut will not be complete.
Thats cool. Very nice work goofing off with machine tools. 😊
Thank you for your comment! It's very important to me 😊
Interesting and informative videos. Thanks !
Thank you!
Is that ever cool ❤ nice work. I'll have to try that out!
Great!
La Verdad,Un Capo En el Torno !!
Excelente trabajo ésta operación es una variante de como fabricar cube In a cube. Solo que aquí está sólido. Para cualquier operador de torno siempre es un reto. Cómo lo realizas en tiempo y forma saludos México
Muchas gracias por su comentario. Significa mucho para mí.
Du bist ein Künstler. Respekt!
Dankeschön!
Nice job!
Thanks! Glad you liked it!
Set your tool height properly!
Thank you. I will take your recommendations into consideration.
I’m completely lost!!! As an apprentice, I cannot comprehend how he’s cut “inside” without cutting the “cross” he’s left????
Good work though!
During the sharpening of the edges of the cube in three planes, such an effect is achieved.
Wow!
Thanks!
That’s not a cube
Well, at 3 and a half minutes in, it *_was_* a cube.
Aside from cleaning up the cube's faces, because their compound isn't centered, I'm not sure why they needed 9 more minutes to turn the work into something that's no longer a cube. 🤔
What would this be anyhow?
You CAN turn a cube in a lathe as long as you have a four jaw chuck and a way to check your stock alignment, usually a dial indicator.
Just need to surface at least four sides equal and true parallel, then hog away at the ends until you get the same measurement as the other two true and parallel sides.
Sadly, even I don’t know the purpose of the extra steps. Fancy cube is fancy, though!
Hi! Thanks for your comment! You can turn the cube on a four cam chuck, but not everyone has it, you can make a cube with an accuracy between the edges and parallelism of 0.01 mm, but it is not necessary for this particular part. In this video I showed that you can make this cube on a simple lathe in a three cam chuck.
That tool needs centered.
Hello! Thanks for your comment. When machining titanium, I place the tool slightly below the center, so the surface finish is better and the cutter does not dull longer.
in all the years ive been useing lathes started11 or12 ive never foumd the need to make a cube just for fun made rectangular parts they dont come out as good asmilling
Hello! You are right on a milling machine to make the cube and its similar parts easier and better, but not always have a milling machine so I have to turn on the lathe ingenuity.
Reversing the cross-slide without retracting the tool is not an ideal choice for a nice surface, I recommend changing this.
And unfortunately you left out the most interesting part. How to clamp the material across in a three-jaw chuck without it flying all over the shop. I had to pause the video and it still wasn't easy to see :-)
Hello! It is not necessary to retract the cutter at the intermediate stage, the main thing is to move it away from the surface during the final turning operation.
You have no idea what you're doing, after seeing you hold a four sided piece in a three jaw chuck. And have you ever heard of setting your tool height?
was impressed, then confused, then more impressed
Thanks!
