Guys, on your new(er) machines - say 2016 or newer - does your coolant flow suck?
IOW.
I have some 2006 machines with the older style coolant pumps.
When it's turned on, the coolant appears almost full blast at the nozzle in no more than 1 second.
Same thing in reverse, when turned off the flow immediately begins to diminish, and in less than 3 seconds all there is a small drip here and there.
This is even on the VF4 with quite a bit of hose distance in the head.
Now on the new machines ( 2016 and 2018 ) there is the new black pump, and it works like shiit.
One of them takes 2-3 seconds for coolant to appear, and another 3-5 seconds to get to full flow.
When turned off it takes maybe 5 seconds or more for it to crawl to a dribble, another 3-4 to just drip.
The other is far far worse. I routinely have to turn on the coolant just after the toolchange, and give a few seconds of dwell in certain cases just to make sure
the tool doesn't just plow into the material with no coolant.
This didn't just start all of a sudden, it was like this from the word go.
I'm about to tear into the friggin' things and prepared to toss these shitty pumps if I have to, but wondering if others have noticed something like this.
Thank you!
