- In this video I walk through the lubricantions to avoid and which to use on your CNC machine to keep it running.
Staying on top of vital maintainance with your CNC is essential if you want to avoid expensive damage and maybe considerable down time. This is the first in a two part video on this subject, the next video being about an essential routine you need to do, every time you start your machine from cold.
Bonus comment, a solution to the clicking backlash nuts problem.

Agreed on the rankings, although I have "way oil" instead of "machine oil" but it does not seem much different. I recently purchased a used (and abused) CNC machine. There was a ton of grease (hard to determine exactly what, but I suspect the "red and tacky" automotive grease) and even more grime on the outside of the bearing blocks. After disassembly of those bearing blocks, the bearing balls themselves were entirely dry. Even though they were in poor condition, the wipers on the blocks were still able to reasonably effectively kept the grease outside of the moving parts. It does not seem that many people know that the grease zerks on the bearing blocks are there for a purpose.
Sounds like you were lucky, I hope it was a bargain, they're the best buys, ones that only need minimal TLC to bring back to life!
I'm going to give 3 in 1 a try
Some new machines will appear lubricated, but this is only a preservative grease that should be removed and replaced with the recommended grease. Not enough users do this and the machine slowly wears out.
I generally just find a manufacturer I trust (in this case, hiwin) and take their recommendation. Hiwin g05 (their standard grease) is an ngli 2 grease. I dont think most routers qualify as high speed in their eyes, but their g04 grease says its grade 260-280, which I assume means the ngli worked penetration test, which puts it in ngli 2 grade as well.
They also do say that you should choose the lubricant that makes the most sense, whether it be grease or oil, and they say not to use ptfe, silicone, or graphite.
Ive seen a lot of people recommend mobilux ep1 as a good lighter weight alternative as well, but I wouldnt be afraid to use a high quality ngli 2 grease.
As I mention, if your machine comes with a recommendation then you should follow it. My only caveat and the same with all the types you mention, which I confess I know nothing about, the lubricant needs to be addative free.
Slideway oil is even better as it has specific bearing lubricant additives and will stay longer attached to metal linear bearings and the lead screws, they also have the benefit of coating exposed metal to help prevent corrosion and it does not seem to leave a residue that holds onto dust so another win on that front.
Slideway oil and machine oil can be the same thing, depending on the grade of machine oil, but yes it is another name for it.
😂some people used vegetable oils 😊
Really?
