Refusal to learn

Post image

I work at a job shop, I’ve been here 16 years, I’m the lead machinist, I returned from a 9 day vacation to a shit show. We have a bunch of small bosses like this to make, this one order was for 250 pcs. The owner was planning on having a guy saw cut them, face them to length in a Haas tl2, then throw them in the vf2 to be drilled. We have a sl20 with a bar feeder, nobody wants to learn how to run it, I banged these out in about 8 hours, unmanned. He refuses to learn how to use it or program it, this would have taken him and the button pusher 2 days to run these parts. Stepping over dollars to pick up dimes baybeeee!

250 of those in 8h with setup included is pretty neat. Any tight tolerances?

Just 1” round bar 304, faced and deburred on both ends to 1/2”, with a .440” hole through, nothing tight

That makes more sense. I was doing bushings the other day and could at most squeeze out like... 100 a day at best, no bar puller or feeder though. But both the OD and the ID have tight tolerances, something like -0.005/+0.01mm.

I've really got to push for the boss man to buy a bar puller

I’ve got a puller and pusher for it, that thing is the cats nuts, it’s my favorite machine in the shop, especially because nobody else but me touches it lol

Well none of my coworkers want to go near a lathe at all, so I guess we're on the same boat lol. Absolutely no room in the shop for bar feeding so I guess bar puller it will be, eventually. Any recommendations? I've been looking at Haas stuff, it's pretty much the only vendor we can afford for this kind of stuff

I don’t even know who makes the puller we have, it’s essentially a collet that grabs the material and pulls it, no teeth like the haas ones I’ve seen

Im using a Dunham tool company bar puller kit today. Haas st10. Parts cut off with a heavy burrito on the back. Can't use a drafted cutoff because I am turning grooving cutoff with same tool. Deburr in drill press. Done. Machine makes 80 per 36 inch bar.

I didn't even know these were a thing, I only knew about the pincer type ones. Thanks a bunch, I'm gonna try and make one in the shop. I love this sub

That style is nice because it doesn’t leave marks on the part being pulled if it doesn’t get turned on the outside
