I have always had problems getting enough coolant pressure on this machine to use an index-able drill even have one of the wash down ports plugged. Today I had to tear into the small block on the turret housing where the coolant goes thru and meets up with the backside of the turret. Needless to say it had its fair share of crap in it.
While I had it apart it appears that the inlet side of block has an Allen head screw that I think holds the brass bushing on the other end that holds the Teflon? seal that touches the back side of the turret. There doesn't seem to be much room for the coolant to go around the screw head and enter the port, real screwy design. Also, on the top of the block there is another setscrew that has a sharp point on it but doesn't seem to be holding thing, could this be a pressure adjustment?
I didn't have time to monkey around as I needed to get a job finished but now think I should have left that screw backed out some to see if I could get a little more pressure. I need to make a new seal for the turret and was thinking about making one out nylon.
For those that have QT-8 and have probably had similar issues what do you think? I'm sure open to ideas
