Actually yes, this specific issue is a Haas problem. However, chip issues in general aren't by any stretch confined to Haas machines. There are plenty of higher end machines with chip removal problems, some of which are far more serious than the Haas chip basket issue.
For starters, the job has to be paired with the right machine. In your case, your machine could work for running smaller parts with less material removal, but probably not the parts you're currently running in a lights out setting. You'd probably want a different machine, maybe a horizontal that does a lot better with high volumes of chips.
Second, lights out can mean a lot of different things. It could mean 100% unattended production, or it can simply mean that the machines run without the supervision of highly skilled labor, but lower skilled maintenance personnel can check up on the machines every few hours to manually clear chips, swap out chip bins, top off coolant, etc.
That makes sense, never thought about it like that, always thought it was unattended.
I think something like a small pallet changer would allow me to run an extra 3hours, if I do a probe tool break detection and figure out the chip tray issue. I'm not there yet, but I'll start thinking about it.
