Let's see some machine work

And i thought you were my friend.

"Were" is the key word here. And that's what you get for thinking.  

[mklotz70]

cool!! Thanks!

Asshat.

I just tooled up our new (new to us) Kitamura Mytrunnion5.

 

Used all Lang quick change withholding like I do on all our 5axis machines.

 

96mm Quickpoint set into a machined sub plate.

 

 

I then machined a plate with locators on the bottom and mounted 3 52mm Lang plates. On top is 2 Lang77 vises. This configuration allows one or two vises mounted in like 20 different configurations. I made more tooling that i don't have pics of.

 

 

 

First piece of stock I cut. 4"x7"x17.5" 6061-T6. I'll post pics of the finished part tomorrow.

Man, you guys get to work with some pretty cool machines.....we just got a brand new Chinese made live tooling vtc/vt/vbm, and it tore the tool changer off of its self the first time we ran it.

[captaingamez]

damn thats fucked up. lol, I have been running dual HAAS horizontals on this crazy 4 axis setup for the last week, the parts run should finish up on tuesday.

[Josh K.]

Here's the part I made. These are for a F35 assembly jig.

 

All the holes are at different vector angles.

 

Parts are done in one Operation and I leave a 0.010" skin that allows me to break the finish part off and remove the skin with a file.

What's up with the red tag. That tells me it didn't pass inspection. Impressive part...

I was going to say the same thing. :lol:

[Josh K.]

The tech that installed the machine missed the rotary centerline by 0.003" in the x-axis.

 

That was literally the first part off the machine and the holes have a true position of 0.008" so it was bad.

 

It was practice ;)

 

The machine is great though. I'm super stoked. I flew back to dc to inspect it when we were interested in buying it. Its got a 20K Big Plus Cat40 spindle and 100 tools :)

[mklotz70]

That's a pretty big chunk of AL!  Do you guy order it to size or cut it in house?

[Josh K.]

It was a 4"x7"x10' bar of extrusion. We cut it to length.

 

Its funny I thought the machine might be too big for us and the first part was a challenge to make because it was too big...... had to do some creative stuff to fit the part within machine travels and avoid collisions...

[q-tip]

I wish parts that were too big form us to do were that small...in reality they're the size of Bertha the tunnel boring machine (seriously they asked us to quote fixing it, but it was too big)

[mklotz70]

Thanks Josh.  For some reason, I was thinking it was a good bit bigger than 4x7.  Looking at the red tag and Rockauto mag now, I can see the size perspective better.  Cool part!!!

A little award I did for the ZCON this weekend. It's for the head designer of the 240Z Mr Matsou.

The Z car Club of San Diego asked me to come up with something. This is all I could come up with.

[mrbigtanker]

Where's my award dick.

[TENDRIL]

 

 

what would you pay for this? unknown hours at this point

 

its listed at 4k obo

[Mattndew76]

Come with 4000$ in your pocket. Inspect it for run out and tilt with some indicators. offer 2000$ to start. Have a price in mind though, and don't be scared to walk away.

[captaingamez]

Frankly the prices on Knee mills lately are astronomical, I wouldnt pay any more than 2000, and I myself honestly wouldnt even be looking at it for that price unless it says Bridgeport on it. Auctions are your friend too with this stuff, see if you can find local equipment auctions of industrial places that are going out of business.

 

Check all the ball screws, as Matt said test XYZ axis with indicators, check the spindle for runout, turn it on if possible, inspect the bearings (make sure they dont sound like a cement mixer)

[dr.feltersnatch]

It has a dro, power feed and a few accessories but I dont see $4k sitting there. Personally I would be looking at around $2500 for that setup.

Maybe worth 4k if it was a series 2 Bridgeport, but I agree with the Dr. $2500 is all I see. If it comes with a tone of GOOD cutting tools might be worth the $4k

damn really?  boss musta been pissed.

Will they ( chinese company ) replace it?

They broke it :lol:, they installed the machine and were testing things and it literally just fell off. That good quality sub standard non graded Chinese hardware

[RatVonDude]

I worked for a guy a long time ago that kept giving me shit for only using air tools. My air hammer was made in Italy and has been a trades standard for over a hundred years, he kept saying it was loud and useless, he also thought this electric "flexible shaft" p.o.s was superior to the air driven pencil grinder that I had. Idiot, the thing literally blew up in 2 minutes and whipped around the shop for another minute, I finally got a boot on it like it was a snake and killed the power

 

 

 

THIS ^^^^^^^^^^^^^^^^        

vs. THIS  ^^^^^^^

[q-tip]

I hear you. These machines are total pieces of shit. On the mill the slots taper .030 from one end to the other and they are .015 from being square to the edges of the table.
