What's wrong with this picture

[Shotout]

OK I saw this in the shop today. After making certain it wasn't for one of the jobs I had released I tried to talk to the fellow about what he was doing. Keep in mind we have an R8 collet to fit this end mill. Since I wasn't convincing enough I'd appreciate it if the rest of you chimed in on this setup.

He's the bosses son?

At least he didn't have the quill all the way extended.

Is he still working there tomorrow?

He just bought stock in Albrecht Chuck Company?

Ignorance is bliss. I have stripped down another's setup to discover straight double angle style collets crushed up inside ER (taper collet) chucks...

the problem with the set-up is that the paper print he has is too close to the oil and it does not have a plastic job folder around it, its always embarressing to have to go to the customer asking for another print cause you destroyed the org he sent.
I would take him into the office and and explain quietly how and why plastic job folders are a MUST, if you have a black board make him write 100 times

" I will always use a plastic job folder from now on"
he will most definately not forget it

Quill: Only 3 inches but the picture was to blurry to post

Let me guess, he just might be in the top five of the best machinist in your state?

Ladies and gentlemen, let me introduce you to the all-sixteenths adjustable collet holder! Available soon at a tool dist. near you. Hehehe.

It looks a bit like the self-tightening chucks that have an integral shank; I.E. no Jacobs taper to come loose.

I have used this type of chuck for holding small end mills and they work perfectly well; really there is not any risk involved provided they are the integral shank chuck, the endmill is small and you go modestly with the depth, stepover and feed.

Grabbing hold of a 1/2" two flute and plowing full width two diameters deep at 10,000 rpm and 100 ipm could be a different story.

Is he an experienced guy?

That air nozzle isn't exactly OSHA approved is it.

[fatal-exception]

All it takes is to destroy that part, and he will use the correct holder next time...unfortunately at your expense.

I have found that a novice can get away with this kind of thing time and time again, yet an experienced guy (who knows better) will smash things up in no time at all...sort of like a 'Murphy's Law'

Instead of

'If something can go wrong, it will'

it would be

'Something will go wrong, once you KNOW that it can'
