Doug Grieve sent this link to me. Quite a machine, hey?

Nice machine SSS, little rich for my needs in our shop.
This is one we have. Saw it on You Tube and had to have one.

It's nice, and better yet Clint has to program it not me. :-D.

I don't think I could use that machine, Johnnie -- the music would drive me nuts. :roll:

Is this machined from round stock crank superior to one made from a forging? I always thought the forging process aligned the crystalline structure in a manner that gives the crank steel more strength.
-
Fascinating.
I have zero knowledge about machining. Why is lube/coolant used for some cuts and not others?
-
I'm no expert but anytime I've seen CNC machines in operation you can hardly see anything for the spray of coolant. I imagine that the coolant was turned down or off where they felt they could for visibility purposes for the video.

Slim- I was more impressed by a German machine that is "total" metal shaping- not just removing, but adding material. It uses laser-deposition, but beyond that I don't know much about it.
-
Some of the carbide inserts are designed to run dry. If you put coolant on them they will fracture due to the high heat and rapid cooling caused by the coolant.
-
Apparently an exersize in machining, not a crank for a real engine but definitely slick.

I noticed that the various crank throws were something like 90 degrees apart -- not 180. Not a flat plane, not a X-plane -- so what was it?
-
looked like single journal on the ends and a double with offset journals in the middle = V6.

Looked like an odd fire V6 on one end, a common 2rod pin in the middle & a single rod pin on the other end. I'd like to see that 5cyl engine! :-D

Slim, I think that most machines are sold to men, thus the Porno music is to help loosen up your wallet and spend some money. :-D
If they didn't turn off the coolant you'd never see the machine doing it's thing.

"Porno music"? Is that what you call that stuff? You must go to different porno shops than I do - or maybe it's just Texas porno music. :-D

Super cool machine. Super expensive.
If you are a low volume engine manufacturer that might make sense. The total machining time would be very long.
Several machines doing the different jobs speeds up the process. Causes dimensional stack up problems too.

Accuracy is the best justification for these types of machines. The more times you have to set up a part, the more chances to screw up. We have parts that take 5 setups to machine with conventional machines that we do in 1 on the HQR 200. In no time, all things considered, the extra cost of the machine pays for itself.
