In the future, a little detail for those of us who have no idea what this is, or what was accomplished and why it mattered, would be greatly appreciated.

This is a cnc mill. The operator is very close to causing a collision between the spindle head in the top middle and the metal assembly on the left. Machine tools are generally quite powerful and fully capable of tearing themselves apart in the hands of careless operators.

The spindle in particular is quite vulnerable to such collisions and they're also expensive. Even on small cnc mills, a new spindle can easily cost more than a car. On large machines spindles can cost more than a house. Most likely this operator would not be allowed to run a large machine. Mildly surprising, given some of the comments, that the owners allow him to touch the controls at all.

This is by far not the closest i have machined. But usually i don't remember to take pictures of it or it's impractical to stop the machine at that close point.
Whats the closest you have come?

[–] Norman_Alexander 0 points 1 points (+1|-0) ago 

I don't come close. I crash the shit. Not bad enough that we have to replace anything or have a guy come in but we just have to reset all the damn turrets. That's probably why they put me in the office.

Ya that's to close. It's been quite a while since i had a bad crash. And it's most often just stupid mistakes. Situations where things get close i take my time and don't crash. If it's to close, i change the setup and programs.

@RAMASULE, @whipcracker, @obvious_throwaway1, the red cyrcle is where the machine came close.
And the river of milk is coolant for the milling cutter. Its a water oil emulsion that cools the cutter and part, lubricates the cutting edge, flushes away cutting chips, and provides a short term corrosion protection.

I know what coolant is, was just ribbin yeah.

Tool lube ;)

That's solid looking shaft you've got there.

[–] Germ22 [S] 0 points 0 points (+0|-0) ago 

Smallest shaft i machined at that job so far. Which is why we had worries with clearance.

[–] RAMASULE 0 points 1 points (+1|-0) ago 

All I see is a river of milk. Is the clearance between the left lathe bit and the big chuck bit?

[–] whipcracker 0 points 2 points (+2|-0) ago 

Yeah whats with the milk.

It's cutting fluid. Cools, lubricates and stuff.

[On small machines] there's a small aimable nozzle that just runs a continouos stream of the liquid.

Edit: "on small machines" added.

Hard to tell scale from picture, what's the diameter of that shaft?

[–] Germ22 [S] 0 points 0 points (+0|-0) ago 

Hmm... if i remember correctly it was around 8"
