I took in a nice job with 304SS truebar. Since it ran slow I split the delivies. 1st of 3 ran fine...when I went to release the 2nd material was no longer available...from them or anyone...except Parker Steel had a metric crossover that was close...but it's a premium plus shipping.
With little choice I had to have 304SS plate sheared and edged...wonderful stuff to be drilling, tapping and milling.
A good amount of dialing in the speeds, feeds and edge prep on tools to get it to run consistently. But by days end I'd be running lots of 8 parts in two machines trouble free. I had warning a drill was on its way out when a squall turned to a squeal...end of that cycle just change drill out and continue. Easily 1000 tapped holes between changing a tool with a telltale notification from tool that it needed to be changed.
Now comes the part I do not understand. I come in next morning, warm up machine 15-20 minutes, cycle through program with no parts a few times as the guys come into work. They load up machine and I go in to get office work started only to have them standing at my door, drill broke, which took out the tap. Sure enough the tip twisted off on the drill.
Now I hear the drill in the other machine squealing like a pig and both machines are down. New tools are put in and they just don't last I have to start tweaking the programs speeds and feeds dialing it in again...finally both machines are producing parts again consistently.
End of the day it's running good I stay a fewours to get up to speed, change out tools for fresh before I leave so in the morning All is fresh. Run a few parts all is good.
Next morning drill is squealing on the first part, tap breaks in the other machine,
This went on every day for a week...ran great at the end of the day and wasted at least an hour or two the following morning till machines just ran...
So, any ideas why?
I thought machine being colder it may have lagged a few split seconds hardening work surface...material work hardened very easily.
Yes, with every worn or broke tool I pulled out all just the parts, replaced with new blanks
But machine was warmed up and my playing around trying to dial it in didn't have machine doing much warming up with my changing tools and tweaking program.
