Robin, I wonder if a boring bar with thru coolant blasting away would help?

The grooving bar and the 55º bar have through coolant. Not high
pressure though. Our coolant pressure does nothing against this chip
nest. Totally useless.

I'm wondering about forcing the coolant through a small nozzle to
increase pressure. We just installed a fine stainless steel mesh
filter after the pump as the tool holders were showing up with chips
in them after several hours of production. If a chip ever made it
through, it would plug a smaller nozzle. Would not result in a crash,
but rather scrapped parts. Not sure if our pump can keep up with this,
though I should really just try and see.

Robin, I also had to put a fine mesh filter on both lathes and mills. I was surprised at how large a chip could get run through the coolant system.

On a general coolant note these guys have a huge selection of coolant nozzles:

I use these a lot on my lathe: http://www.qpmproducts.com/p-blackeye.htm
