If you over fill with grease it comes out and the same is true with oil. The trick is to regulate the flow or pulse small quirts at regular intervals so just enough to coat the bearings with fine smear on rails. It's not difficult really.
My mill as got programmable lube system which can pulse the pump and it just oils the bearings and ways nicely with very little to no excess, certainly not enough to contaminate anything.
You can buy these cheap enough now and they even do ones which will pump grease.

Same thing could easily be made with an arduino cycling a pump.
