Grease problems . . .

[Jig Maker]

I cut only aluminum with with my router, and even though I use a vacuum it's not doing what it should and I need to redesign it. In the meantime, the chips are building up on the grease of the worm screws and the x screw especially gets clogged. Coupled with the fact that the machine operates at whatever the outside temp is, the white lithium seems to get too gummy once the temps drop below the low 30s.

My question is what should I use to lube the worm screws, and should I use the same lube on the guide rails for the linear bearings for the x and z axes? I laid the x axis worm screw beside the y axis after I'd cleaned the x, but it was much worse than the y you are seeing pre-cleaning.







The x worm screw had so much gunk built up at the female part it rides on (sorry cannot find a manual for this machine don't know the nomenclature) that the servo was seeing enough resistance to trip the reset button on the back of the controller.

I'm thinking of trying tranny fluid. Bad idea?
