CK5 - The Full-Size GM Off Road Community

chect this part out, its some kind of manifold air craft part from a solid piece of Titanium. we coat and finish grind the two bigest bores on the part. I dont work on this part at all when it comes in the shop but I allways look at it everytime it comes in the door. who ever the programmer that programmed this and if he was also the machinist that machined it is one bad ass programmer/machinist. the number of operations to do this part I bet was alot. there is so much profile machining on this thing. and everything is close tollerence too.

more pics. pictures do not do this justice.

That is incredible. Thanks for sharing.

that is a damned cool looking part

how much would one of those cost? lol!

j

That's a LOT of hours behind a computer.

That thing is sick, whatever it is.. Definitely a work of art....

I bet its a mil component. Probably only cost 8mil.

More like how much do those guys get paid :eek1:

Man that's beautiful!

and to think I thought I was getting pretty good with a crescent wrench.....



awesome

holy crap i have done a little cad and machiening, but crap i wouldent know where to start, that thing is daunting!

very cool!

Nice. Looks like the body of a turbine engine fuel control. Dunno which engine, but it's a newer electronically-controlled one, judging by the markings at the various ports.

I like the old-school CK5 mousepad, and CK5 up on the monitor at work, too...:D :D :D

DOE!, busted :doah: :haha:

You need to change your desk blotter also.....It's not March anymore!!! :D

thanks, just did that :waytogo: had to get the important phone numbers first.

Incredable

It definately looks like an aircraft part of some kind. Yeah, it does look like some engine part or a hydraulic systems part. I've seen some pretty weird parts working on jets all day, but most of the parts I see are painted and covered in oil and hydraulic fluid. That thing is shinny and clean. I'd like to work with parts like that all day. I'm not a machinist but I work next to the machine shop every day and I have nothing but respect for someone who has the skill and patience to produce a part like that.

Awesome!

You can bet that part was designed, programmed, and machined by several different people. None the less, completely awesome!

only a f'n engineer who has never cut or machined anything in his life would design something so complicated like this. ofcourse they think "you just push some buttons in a computer a hit start on a cnc machine and is done, whats so hard about that?"

I know I have worked with alot of them and that is the general concencess from an engineer about machining. "Disney Imagineers" engineers are some of the worst. I have seen and worked on parts where a surface or diameter that touches air meaning no mating part, its just the exterior of a pump body that could be plus/minus .03 or more has a plus/minus .0003 tenths :eek1: .

a good cnc machine that has not been crashed will hold incredable tollerences. I did a bunch of parts for Disney that the parts were so big that the design of the part would allow the part to flex just from its own weight once it was machined. the concintricity of 4 bores that were supposed to be in line was so tight it could not be held to the .0002 tenths concintricity they required. the part moved in the machining process from the stress in the material and the removal of so much material that it was imposable to hold. only after we tried five parts and were able to hold .0005 to .001 at best did we call the engineers at Disney and say theres no way we can hold that tollerance. then they said no problem we will do a engineering order change and let it out to .002 will that work for you. they told us the mating part was way smaller then our bores so it did not matter if it ran out .002 at all. :eek1:

these parts started out as 350 pound blocks of steel and weighed about 78 lbs after machining and EDM work. they took four setups to machine and about 17 hours of machine time per part not including EDM time. sorry rant off. :D

or you could take it another way... as a compliment. They simply assume that you have the mad skillz to machine pretty much anything, which allows them to design stuff however they want. :thumb:

I've worked in the toolmaking/machining field for a bunch of years and if I had a dollar for every time an engineer said..." It didn't look like that when I drew it" I'd be a rich man!

We have two MoriSeki 6 Axis mills that machine similar parts to what are pictured, pics don't show how truly complex that part is! :bow:

I believe they refer to them as "fuel dispersion manifolds" , might just be what we call it?

I love your pics rdn2blazer, just don't get caught put'n them on the net ,
my employer made the entire R&D dept. sign confidentiality agreements!!

Nothing quite like 5 thou on a sheet metal screw hole!!!

Engineers are a funny bunch. We are always bickering with them at work.
