Crankshafts being made in Pakistan

doublebase said:
That machine could take his entire body and wrap it around that crankshaft and spin it until every single piece of him hit the ceiling. And there’s unfortunately videos out there to prove that.

The only chance this guy would have is his shirt is a button done with what looks like very light material...perhaps it would tear, but if that were a Carhart sweatshirt? he’d be disintegrated. Scary stuff.

As someone who runs a lathe, you must absolutely respect them because they don’t care if you don’t care. We had a guy not catch a programming mistake on a brand new Okuma CNC lathe and slam the turret (programmer put a G0 aka rapid/as fast as possible instead of a G1 aka feed) into the chuck at 1400RPM… it ripped the turret off its mount.

Thank you for your outdated and myopic comment.

What you're likely describing is the decline in manufactuting's overall contribution to GDP and it is a worldwide condition. As economies mature other sectors become much more valuable than manufacturing.

Can you help me understand why this is an issue?

So I zoomed in but still can't tell what's being manufactured in these pictures.. What is being made here?

Electronic components for the television/film business.

High end signal conversion gear, recorders, I/O cards for editing systems....

The one rack unit converters here are about 9K a piece. (sorry about the orientation)

Well we didn’t need those machines here because we don’t make anything in this country anymore.

No those machines are usually old and outdated from ww2 thru the 60's. Most modern machines are CNC and provide much more accurate and complex machining but are very expensive and require a highly trained workforce that knows CAD/CAM and more computer skills. The Cinncinati Machine tool company was dissolved in 1970 so the machine being used is at least 50 years old. Nobody even makes parts for these machines.

Ok … since you mentioned that … when I was a youngster - got a new 56” Bullard and the programmer found me doing manual rough cuts on some horrible valve bodies. Said he’d add a step.
I was on second shift right at 3PM hand over and both of them said you are ready to hit go.
It was set up in reverse - lost all perspective and line of site … crashed the turret block. 😳
Datum was also programmed wrong …
 
Cincinnati Milling Machine, later renamed Cincinnati Milacron, built a lot of long lasting machine tools that are still in use today, which is amazing because they stopped making most of their machine tools in 1970, over 50 years ago.

After they became Cincinnati Milacron, they sold the machine tool business to Unova in the '90s. There's plenty of older factories still using them, go on a random factory tour-you'll see at least one. A LOT of them made their way overseas when the factories they were in were bought out & closed.

Ran their indexing chuck CNC lathes .., and yes, first time it indexed while rotating I got behind that brown Kennedy stack up …
 
Video shows pretty much how crankshafts are made anywhere. Different construction of the buildings the operations are in. It not rocket science, like people seem to believe.

Absolutely agree, the machine doesn’t care one bit...and the operator wouldn’t know what’s happening until it’s too late. Scary stuff.

Yea, those look like V6 cranks, either that or it is a very heavy-duty 3 cylinder with massive con-rods.

3 cylinder Perkins diesel engines. Low RPM, low power.

Really there are a bunch of steps they either skipped showing, or just didn't do. I suspect these are cheap, knock-off parts, that will have nowhere near the longevity of OEM parts.
