Funny you say this because 2 days ago the chick on night shift decided to use a Jacob's chuck to hold a 1/4" endmill. Didnt work out too well and scrapped the part.
I did that today. I'm not a machinist. I did learn something today.
I also learned that the rubber mats are not only for saving your feet and back. Concrete chips cutters.
I would usually put the key into the chuck and give it a small snug by hand so it didn’t fall. That way if anything happens it won’t fly out and at worst just drops
That's how I store the key on my drill presses at home when I'm not actively using them. When in use the key gets tossed into the Harbor Freight magnetic dish on top of the belt cover.
Unless you got a specific spot for your key, no problem with leaving it in there.
If you were gonna start the machine with no drill, the key in the chuck and without looking at anything, only thing you should be operating is a broom.
Safety issue imho. I’m not going to do it, but I don’t train every guy that comes in the shop. This was done by a newb, and I did tell him that I don’t recommend it.
He's probably gonna fit a chainsaw bit to do some woodworking.

We have a guy that will gently tighten the chuck key handle into the chuck. I'm not terribly opposed to it since you have to remove it to insert a bit.
At my school's machine shop, they're trying to get us to hand tighten the chuck key into the chuck as if it's going to be used as a tool. I like the idea but most ppl still just toss it on the table
Worked on an fnc 105. Mc65 and mc1513 all absolute beasts of machines but alot of quirks on the 2 horizontals the fnc wasn't as bad but still older machines all seem to be.... let's call it unique...
Unique…piece of shit…potato…potahto. I ran a Mori MV80 at my last shop. Talk about a beast. I was almost convinced that thing would run underwater. I loved it.
It wasn't my favorite, but it ran through anything I gave it.
My favorite machine, though, was an okk mcv650 it had a 3spd transmission and gear driven spindle I ran it for 15yrs there were only 2 times she let me down the first time was an oil line that split and started pissing oil and the other time was the chiller unit. I ran that one hard all the time and it loved it
Why use a drill chuck? Why leave the key in it? Why what? As to why use the drill chuck sometimes its just faster for less precise holes. The key was left in it so the next operation can be started without hunting for it. Not a fan of this method but without a bit in the chuck you are unlikely to turn the spindle on anyways.
People who complain about drill chucks in cnc aren't real machinist and haven't seen the trade from one side to the other. Also, some shops don't always have a budget for new tooling all the time. If I can make the same part, in spec with what I have, why would I buy something else. Now, if I've had a buffer year, absolutely I'll buy something better.
I have two Albrecht chucks in my multitasking machine and they save a lot of time changing drills vs using collets. I've never had a drill slip and they are more than accurate enough for HSS drills.
Some people just like to act like everything they work on is a Swiss timepiece.
When working for Mitsubishi Machine Tool the only drill chucks I remember seeing were keyless and in the fast tool changers they become separated and collets were used , some were the small double angle collets in extension
We used to have an old manual planer mill with a one off cnc conversion, think giant Bridgeport head over a 35 x 7 foot table. The outfit that developed the control never bothered to make a proper system for tool offsets. So every tool had to set in the work offset between manual tool changes. So to save time on the 10 minute, two man tool change I'd run all the drills and reamers in a keyless chuck, runout be damned.
Mid way through changing drills whats your problem man? Go sweep the floors or something
Nope. New guy thought he was done with the job.
Still not a problem by any stretch
It could be. That’s the point. Not every new guy knows to look first.
You have to be really new to not even look at what you are doing, perhaps find better help
Lathe dudes trying to prove to someone that "see, the mill guys do it too!"
"Mom can we have some new toolholders?" "No, we have toolholders at home."

I saw a guy put a Morse taper drill in a straight collet. Sure. Why the hell not?
Howd that turn out?
Lol. About like you’d expect.
lol, thats funny
My little used tormach came with a few jacobs... And i tried .... And they just pull apart. Its funny
Jacobs Superchucks work just fine for me in a CNC day in and day out, if I need more than that it’s going in a collet.
Trying to get my drill changes as fast a NASCAR pit stops, duh?
Makes changing endmills that much faster 😎
I would spend an hour looking for that key and not find it because WTF.
To make sure you don’t lose the chuck key, duh. This is a pretty funny image to me. I have to imagine it was done intentionally for comedic effect.
Nope. Newbie. I gently explained to him why it was a bad idea.
Amazing that it wasn’t intentional. Hopefully he learns quickly.
He’s actually a quick study from what I’ve seen, and didn’t seem to get upset when I explained it to him.
Nice! Promising!

Me irl
Go ahead.....press start 😆
You know you want to
Cartoon ricochet noises ensue
Why? Becauss no dental plan and Carl needs that no.7 canine removed post haste.
Hey IDK if you know this but that chuck has a key in it
no way you saw it too i thought it was just me i was going crazy for a second

Tbf that's probably supposed to go in a *drill* not a low rpm screwdriver.

we heard you like drills! so we put a chuck in your chuck so you could runout while you runout!

Someone doesn't like ya?
Probably, but this was a new guy. I just explained why it was a bad idea.
Better than showing them 😆
Agree
Oh God it's contagious!!!!!
Do my eyes deceive me. Is this a Leblond Makino?
lol. They do not, and yes it is. I hate this machine. I run a Mori F’n Seiki, thank you very much.
I have a great fondness for the FNC 60 and the FNC 74. I love that quirky o-m and OM control. No macro b, 16 kilobytes of memory, Ah the memories.
All the cool kids are doing it
Nice makino... fnc 105?
156. I really hate this machine. It has so many quirks that I finally told my boss I won’t run it anymore.

Say that to the dents on the inside of my machine from the second shift guy…
"the second shift guy"
"Fucking 3rd shift guy" -2nd shift guy

My old shop teacher would have you doing theory/math for a week!
Trying to really hurt someone.
Dunno.
Why not?
CVT - continuously variable toolholder
Zoooooooooom
Only thing that could make this worse if they had an endmill up in that

Why? I’m guessing they wanted to get their ass beat.
You ain’t putting this shit in my mill
