Probably left by a visiting Japanese engineer , the metrology stuff is a bit less euro-centric.. they even have a HP laser interferometer..
The whole metrology area is temperature controlled to 20C

They have a class 1 room, which has a seperate outer room for the operator

A lot of the stuff they make is used at liquid helium temperatures, and high vacuum. They make their own
stainless steel bellows and cryo fittings.

This flexible stainless coupling is made up of rings of stainless and then manually tig welded.. one ring at a time.

A lot of difficult to weld parts are electron beam welded.

The last picture show a test piece indication the weld penetration vs the surface blow back, a lot of the
electron beam welding is difficult to weld stuff like copper.
That's it!

On the CNC vs Manual question, I think its mostly CNC, but the manual machines are still used every so often, in specific instances they can handle much larger parts on their manual machines, like that big planer/mill in earlier pictures.
They are inclined to outsource jobs that involve a lot of repetition, or are "run of the mill" type jobs, and they seem to go for the really specialized hard to do type of work... lots of x-ray'ing of welds and testing of parts to make sure they are going to be vacuum tight and work at liquid helium temperatures...
Amazingly skilled people and amazing place.

Ray

The thing in the spindle is a Spindle Taper Cleaner. Normally they are timber or plastic with strips of Chamois leather attached.

They are just being extremely Swiss, by leaving it in the spindle socket so dust doesn't get in there.

Nice.
I think my shed needs cleaning. Do you think they sweep their floors with a broom, or just use a feather duster?
I'd hate to pick up the tab on some of the stuff they make and do!
SimonGirl, I don't wanna know about your mild-mannered alter ego or anything like that." I mean, you tell me you're, uh, super-mega-ultra-lightning babe? That's all right with me. I'm good. I'm good.

Truly wonderful Ray. I reckon it's like being a six year old opening presents on Christmas Day when you encounter machines and equipment such as you have seen.
I would have been happy enough to have spent a day just in the Atelier Mecanique.
Fantastique!

Hi BT,
You're spot on, like a kid in a candy shop it's all a bit overwhelming, almost defies description..
Google has just released streetview of CERN, including a section of the underground ring, and the ATLAS detector.
Google Street View Lets You Take A Virtual Tour Of CERN | Fast Company | Business + Innovation
I've only got the link, so I'm not yet sure how to get streetview underground... If someone figures it out let us know.
Last couple of days we've seen the Computing Center, ( and witnessed a little bit of History.. ) and got a look at an interesting experiment to see if gravity affects anti-matter the same as matter...
Regards
Ray

I couldnt get it to work from your link, just pictures.
This one seems to work.

Adding some of my pictures into the mix.

There are some very nice rocks all over CERN, with a high density in the workshops, here is a nice 4x4' Swiss one.

A Machine very close to my interest; an in service Deckel FP2LB.
IMG_1594.jpg
HighRes
Interestingly it had pull dials ?? Which means the FP2LB was still being produced along side its very very close relative the FP3L.

Thats the end of my stills of the workshop but I have a time lapse video I will upload soon.
Next I will post some pics from the CLIC accelerator.

Hi Josh,
Thanks for the pictures.
Even at Cern the plates get used as coffee tables? or is that cup half full of Antimatter or some such?
To those that know about these things. Isn't that an awful lot of flaking on that crossrail?(but then one assumes that the person that put it there knew what they were doing........)

Yeah, but they have so many rocks and they keep everything so very clean.
On the scraping they are not in the habit of throwing out older gear in blind preference to modern cnc machines, which I like, it seems they would rather get their machines refurbished as soon as they wonder outside their required spec, every single machine they had in their workshop was in fantastic working condition.
