"For instance, I've seen MANY operators set into the cut in cold (or hot) weather and take off as fast as the mill will go from the start. That in my opinion isn't good, it causes flat spotting on teeth because the tips aren't at a decent temp yet. I was taught its always a good idea to load a truck or two going a little slower then full out to get the drum warmed up and then hammer away as fast as possible. "
I was taught the exact same thing, still follow it to this day
"Another For instance is the amount of people that have no idea if the back tracks are out of calibration causing the machine to crab, which wears out end ring teeth and holders, I doubt I've seen anyone in the last 10 years that pays attention to such things. Its usually pretty obvious by looking at the side walls of the cut, the one that has no material left in trail usually means the @ss end of the machine is kicked off in that direction."
machine crabbing to one side=HUGE pet peeve of mine, the old pr-800's were friggin notorious for that crap
"And milling people just don't like being told those little cruddy details, they don't care and they resent hearing it at all."
Again, I completely agree. I As far as keeping the machine level...another pet peeve, I even put a little stick on bubble level on my machines for the groundmen too lazy to back up and look, haha I'm anal I know.
" In another thread here, I saw some pictures and mentioned that it is a good idea to try to run a mill as level (front to back) as possible, the reply was....they didn't care and it didn't matter....end of story. Let the company owners replace the parts worn out because the crews aren't interested in taking care of the equipment. Not me....I'll quit before I go out like that
"
I have fired more people for that attitude
"Bean, I ain't never seen a Sandvik drum at all, saw a few holders once with a tooth sales rep down in Texas this year, never run a Sandvik holder either. Lotta folks don't care anything for Sandvik but I think they are aight and better than some others I've used. This year in the Midwest we ran those Sandvik teeth with the double ring of carbide on it, they were excellent on Interstate 94, held up better than Kenametal teeth we had.[/QUOTE]
The one time we were given a sample of sandvik's to run on a pr-800, I was not impressed at all
