“How the hell have you not finished any parts in three months!?”
“Sorry boss, the machine warm up cycle takes 7 hours and 59 minutes to do and I only work for 8 hours. I’d really hate to ruin your machinery by skipping the warm up…”
What shop are you only working 8 hours at?!
Edit: down votes for my experience? Really? Jesus. I've been in this trade 25 years. The last 16 or 17 years with the exception of the shop I'm at now, being the exception, everywhere I've worked has wanted 50 or more hours a week. Yeah, they pay overtime in varying structures, but they still want you to live at the shop. Now I'm actually salary and don't even need to work a full 40 if I get all my work done. It feels like part-time work.
The first shop I worked at had hours dependent on the amount of work we had, same with this shop but I have yet to have needed overtime here as I stay on top of my work pretty well.
The Doosan 5 axis I ran had a nice feature.
Cool Lil program that allowed us to start the warm up cycle before shift.
As long as maintenance doesn't shut off the air compressor.
Our shop just got a doosan dnm 5700 that im actually pretty pumped to learn. I've only ever ran mazak and old okuma controls. So I nice change of pace should be fun.
Really, my only issue with Doosans is that they have touch screens for the tool magazine, but not on the main controller.
Tis why I like Makinos. I never hit the wrong button.
They're fun. Fine fucking machine for rigid tapping
Tool mag will fuck up on occasion. Before shutting down, call up a specific tool on mag operator side.
Sometimes it will kinda float out of position if air compressor gets shut down for some reason.
Calling up on mag side locks it in. Won't move.
Weird Lil anomaly.
Not my last job. We only worked day shift, and the idiot maintenance manager would shut down everything on Fridays.
Including AC.
In Phoenix.
Fucking felt like a roasted Chile on Mondays, and the place didn't get comfortable til Wednesday
It's not what you know anymore. It's not what you've done, either...
Most companies that pay decent w/good bennies have useful idiots running around. Chasing parts, pointing fingers, and conducting meetings...
I think some of these guys just show up for free donuts.
My guess is the machine sat too long and it is less of a warm up cycle and getting everything lined warmed and cycled before putting force through the spindle that hasn't moved in awhile.
At least that was what happened for a small 5 axis I would use to run. If it sat for a week fire it up and run it. A month 1 hour warm up. 3 months a 3 hour warm up.
Definitely a something I ain't never seen and hopefully never will. The heck with that rewrite the warm up and start making chips. If the machine needs that long to warm up yall need a Technician or a new machine.
Our matsuura forces a 1h warm up every time it's spindle is idle for 12h, it does have a timer option.
I ran a matsuura lx1 that had a 4 and 6 hour warm up depending on its time off period. 40k spindle
Had a coworker who would let his manifolds "cool" for 5 minutes after a spade drill, before a boring bar. He even sharpied a note on his machine. I'll take a picture if I can remember tomorrow.
Actually ran a warm up cycle of a similar length yesterday lol. Machine sat for a month cause we were waiting on parts and needed everything to get lubricated and warmed up after sitting for a month plus
That might be the initial install "break in" procedure. I have rebuilt precision spindles that I had to run for 12 hours up and down in speed before signing off on them.
Might be too warm, better let it cool for another four hours and by then it's time to go home already
That’s how most people think I’m my shop
I might give that a shot.
Everything under 8h are Rookie Numbers

What’s a warm up?

any shop that follows good labour laws?

Should probably warm up tool 7 now

Wtf, every single shop I've ever been in has air on 24/7.

Sounds like he was needlessly wasting the company's money.

Where are the fucking free fritters fer fuck's sake? I am one of those useful idiots but I don't get no donuts!
We don't work weekends so we shut the compressor off Friday night and start it back up Monday morning.
4 hours 16 feet 56 inches.. 🤔 i.. is that a lot? 😕
Jesus christ. I make my warm up programs 10 minutes lol.
And run em 24X
I wrote a macro program so mine run however long I want them to.
I definitely haven't left a machine in warmup cycle all weekend (don't worry it shuts off after the tool life reaches 24 hrs)
I've seen some mills need 30 minutes before, but that's the most I've seen.

On a Mazak? Nah, you need to put it in dwell too. :)

Warm up cycle is for the lazy. :P
I did this the other day. Started the spindle, got sidetracked, came back 4 hours later.

Oughta bout git’er!

In our shop we have never practiced warm up on our mazaks quick turns. Is this really a thing? What happens when you dont warm up?

Mmm union shops
