From the description and pictures I can see a few problem areas:
1) Grease is entirely the wrong lubricant to use. It is too thick and will never liquefy enough to do any good. Use either real ways oil of ATF as Taig suggests.
2) Coolant. If your cutting plastic I would suspect that an air blast system would provide enough cooling without the negative effects of the water. If you must use a liquid then try finding some water soluble cutting oil. This will be no messier than plain water and will actually provide a bit lo lubrication.
3) Keep your machine clean. If your machine if plugged up with that amount of gunk you will tear it up, period. A small shop-vac,a small brush and a few rags are all that is required to have it looking like new at the end of each use. Spending the 15 minutes it take for a good cleaning job will save you lots of time later.
4) If you cutting any plastics with fillers like glass or ceramic then you need to clean up really good as that stuff is like sandpaper.
