re Spindle Lube and Lube Pump

[paynebros]

I could use some help with auto oilier issues I am having on my tree mill journeyman 325. I noticed that the large pool of oil dried up under the Bijurn pump on the side,so I assumed the motor went out and have been lifting the pusher to manually lube, but then I got to checking the spindle oilier system ( Parker) located on the rear and noticed the bulb on top was not moving any oil. I took a job at a machine shop to supplement my Eng. degree skills so i know what a properly working oilier looks like. I took the unit apart and connected it to air supply off the machine and it flowed great. hooked it back up and it returned to not circulating oil. I disconnected a drain down the line a few inches and it flowed again. So is there a fuse, switch or other shut off valve blocking the flow, or just a clogged line I must track down? There is a long silver dial that comes out of the black "controller" but It turns freely with no end or result. I don't want to run the machine without the oil flowing freely so any help will be greatly appreciated!! I see the + - adjuster directly next to the bulb and it did not help the flow.

Whoa, the Tree J325 is a grease pack spindle. YOU DO NOT LUBE IT. The air oiler in the back is only for the pneumatic unclamp for the draw bar. It will only oil when you eject a tool. The Bijur pump supplies the ways and ballscrews only, if there is a puddle under it, either the plunger is leaking, a line is leaking, or someone spilled. The ballscrew support bearings have Zerk fittings, and all you need is an EP2 grease, like shell retinax. Those really don't need to be greased very often, the trees don't move that fast.

Any idea what the little toggle switch on the back of the cabinet does? It is the same as the coolant pump but directly on the other side of that cabinet and it does not stay switched it springs back,but I did not notice anything. Thanks for the lube info, I don't know where I would be without this forum. Well, I guess a ripped apart machine and a empty wallet, Well the wallet is already empty, but machine works.

Sure do. The spring return switch allows you to open the electrical cabinet without it shutting off the machine.
