I recently picked up a PM1440 lathe and I noted it has a coolant tank and pump so that I can run a continuous stream on a cut. I see this used all the time on enclosed CNC lathes, but how many of you guys are using something like this on your manual lathes? In the past I have just used a few drops of Tap Magic (all metals formula) for turning most things, and some stuff I got in an old free oil can that smells like bug poison for really hard stuff like metal and tubing bending rollers.
While the lathe is intended to make money I just don't see me running it continuously every day. More along the lines of -> when all the CNC mills are cutting and the CAM for the next jobs is done I'll make some other parts on the lathe. I may only use it a few days a week. So coolant sitting on the tank will dry up. I can always add water if I used a water soluble coolant of course, but...
Then there is the other thing. The mess. I can see this sort of application throwing coolant everywhere, and there is no shield over the cutting tool. Just over the chuck. On an enclosed CNC lathe its no big deal. It hits the door and runs down into the splash pan, but on an open manual lathe I can just see me being soaked and the tank being empty in no time. Any experience? Suggestions?
