The idea of using two bolts to clamp the part down is just purely genius. It's even more when those two bolts are not on the drawings. lol

[@ChrisMaj]

Haha, it worked prety well 🤣

Great machine that can do both turning and milling. Nice bit of machining mate. Whistling guy must be happy which is good to see👍happy Easter

[@ChrisMaj]

I have enough turning work so they usually take the milling to other machines.

Nice use of clamping on the eye bolts. Minimal jaw clamping force and that is a recipe for very round diameters.

[@kyledombrowski7051]

Interesting part! I use wood occasionally on set ups on HBMs, but I would worry on a VTL the coolant softening up the wood to throw the wood and maybe the clamp out, but it dosnt look like you needed any safety meetings, so all good :)

[@sambembs]

Great vid! But why not clamp on the I.D, then you could've machined the whole O.D in one go rather than flipping it and doing it again?

[@canonicaltom]

That wouldn't save you any steps.

[@FuzzyPanda53]

I'm guessing you use the bolts to not have to worry about warping the part due to clamping? If so that's really clever.

[@ChrisMaj]

Yeah, that was the idea and it worked pretty darn good 👍

[@nicolaschampagne8988]

just food for though, wouldn't it have been less oval after machining if not retained by the 2 bolts ? Or do you use the bolts because you don't want the piece to get out of the jaws? I'm asking this because when I was machining molds, we would unclamp after roughing and clamp less hard without down forces so the mold sits "naturally" after taking out that much material from the big piece we beginned with. I know it was just a couple how Thousandth, but i just wanted your input on this and share my experience. Thank you for the video :)

[@ChrisMaj]

The part was 20" tall and I was holding it only by 3/4" so yeah I used the clamps to hold it in place. The jaws were barley touching.

[@173roberto]

It looks like that lathe is able to index and drill but not milling contours. I'm I wrong?.... at the end of the video it milled! 😱😱😱

[@mattcaesar5781]

Customers be like its not a big deal cut the OD and ID at the same time then flip it over. I got $175.00 for machining lol

Even worse are those who want to provide their own material.

13:40 - Threaded holes as chip-breakers!

[@ChrisMaj]

I was worried that it would break the inserts, but it went pretty well.

[@currentbatches6205]

@@ChrisMaj That insert didn't have the same yellow (TiN?) color as most of the others and I wondered if it were some sort of 'resilient' carbide. Neither you (pro), nor me (strictly amateur) can avoid *all* interrupted cuts. I can usually scrounge some HHS bit from the days of my old lantern-tool-post lathe and 'shim' it into the QC tool holder, but I'll bet you simply don't have any HHS bits around. BTW, that old lathe wasn't rigid enough to use carbide; most all cuts were 'interrupted' on that thing.

[@ChrisMaj]

@@currentbatches6205 It is about selecting the optimal insert for the application and applying it properly in an efficient manner. If the insert has an advanced coating technology specific to the application and it is applied effectively, maximum productivity is ensured.The larger the cutting edge angle the better.

[@currentbatches6205]

@@ChrisMaj "...The larger the cutting edge angle the better..." IOWs, you prefer the cutting edge of the bit to address the hole as far as you (practicably) can from parallel to the C/L of the hole? To keep the entire cutting edge from hitting the cutting surface? If I got that right, dunno what your native language is but please convert "thank you" to that.
