An extremely accurate manufacturing machine - Video

Captain here: that thin stub is a cantilever hanging out of the chuck. Cutting force deflects an unsupported lathe part with the cube of the stick-out length, which is why it bent instead of cutting cleanly. Machinists usually keep unsupported length under about three times the d

My disappointment is immeasurable and my day is ruined

I had hoped for that outcome!

Amazing run out

Couldn't get hard. Happens to the best.

Engineer was excited at the beginning though!

It manufactures disappointment.

Floppy milling for more kinetic energy

As a professional in this field, I got cancer from this video.

Material too far out. Speed too high. Cutting depth too high. Tool not perfectly set. Working with thin parts is a annoying to work with every time. So you learn some quirks but even then... like i said annoying.
