Hello,
Mazak SQT10MS
machining a bar only to come back to a red flashing light. The T32-3 control said something to the effect 'low hydraulic pressure'.
So, I checked the hydraulic oil and sure enough, it was low. Topped it off and started running.
Upon pulling the parts from the tray, I noticed that they seem to be oily. So, putting two and two together,
I assume that the hydraulic oil is somehow finding its way into the coolant tank.
There was a leak (looks like coolant, but wondering if it is coolant/oil) coming from the back edge of the turret. Leaks
slightly when running and a big leak when the turret rotates.
So, I pulled this little block off the bottom side of the turret head thinking that maybe I had a bad o-ring. Replace the o-rings and started running.
Seems to have helped the leaking a little bit, but wasn't long before I the hydraulics started making noise again.
Dang it! Low hydraulic oil.
So, I filled it back up and now trying to diagnose where the oil could be going to.
Does anyone know if the hydraulics have anything to do with this coolant block? It seems a rubber nose on the front of this block is supposed to close the coolant
passage when coolant is called for and then open when it is not called for or there is a turret rotation to a new tool. Do hydraulics push this rubber
nose in and out? Or, is it the coolant pressure that does this?
Where else could there be a hydraulic leak? Inside the turret somewhere? What rotates this turret? Hydraulic or electric?
Please let me know what other ideas you might have that I can look at. Need to get this machine up ASAP.
thx much
Mike
