You probably don't know Jack (O'lantern)!

Best four minutes and eight seconds you'll spend online today. This is a five-axis horizontal machining center (it might even be a six-axis +...they didn't show a good side view of the spindle head).

Very sweet!!
I would like to have seen the multiple tool changes and how they were done and know the overall time from beginning to end.
I know the video was 4 minutes but I'm guessing the whole CNC process was at least 60 minutes minus design time of course.
Good stuff, what does a rig like than run? Any idea?

We live in amazing times. I watched a similar video with a solid block of aluminum being machined down to a complete polished billet cylinder head. Just needed valve guides and seats. Each copy was $6000.00.
In contrast and just as amazing - how they did it old school in 1935:
edit - for some reason the video won't link.

They're not polishing bits. I"d bet the farm that they're very likely CBN cutters (cubic boron nitride). CBN is man-made, and is one step below diamond in hardness. They leave a beautiful finish.

I trained in a three-man tool and die shop, and I was doing things "old-school" on my apprenticeship back in '86 through '90. Our shop didn't get its first CNC until 1991, and it was only a 2-axis Bridgeport Mill retrofit.

Honestly, for the first ten years of my career (including high school and trade school) it was rotary tables, sine bars and practically every other manual tool and setup/layout procedure that was still being used as far back as the 1800s, if not earlier.

And as Miranda Lambert would say....."back before everything became automatic".

Had I been able to peer into a crystal ball and watch this video as a high-schooler back in the 80s, I would have never believed it.

What really caught my attention is this:

In 1935? One of my friends that owns a machine shop just got a Oxyfuel cutter in 2022 to punch out base plates from 1" mild steel. I've been trying to talk him into getting one of those CNC plasma cutters (Arcdroid CNC) for a while now (not so I could play with it, mind you) but no luck so far.

Oxy-fuel cutting has been around a very long time. Those old machines were essentially tracers that followed a template, which is shown on the left side of the photo. They were used heavily in the ship yards, machine building and architectural industries.
