We have MiG welding robots. We grease, and change all the batteries once A year. There are specific procedures to follow for greasing. The instructions say that some axis be greased every year, others every 2 years.
When I say greasing, you are really changing the grease. We change the grease on all axis every year, even if says every other year. If you order A grease kit from Lincoln for your specific robot. You will get
Detailed instructions included in the kit they will send you. There can be damaged caused to the seals if the instructions are not followed. -
It all depends on the robot model, but it is usually around 1 year and half.
The procedure for greasing robots doesn't change much, but the recommended angles for every grease inlet is different between models. So it's better to follow a Maintenance Manual for the desired robot. Also the type of grease varies, so you really need the manual or someone with the knowledge for a correct maintenance.
As for a detailed explanation on how it is done:
- Before starting the maintenance, do a full backup (All of Above and Image).
- We always replace robot batteries and controller with the robot completly energized (not recommended by Fanuc, but we do think it is safer this way to don't lose information).
- After replacing the batteries, we do a backup, All of Above backup and Image backup.
- We move the robot's axis in a easy to reach way (depending on the cell) and also trying to follow the manual as much as possible.
- Then we remove the outlet bolts, when we don't have the correct tools, we put something like a transparent plastic bag and tape around the outlet for all the grease that will be coming out (also the transparent bag is to check on the grease color).
- Use your grease fitting on the inlet and start pumping, it may take a few to start seeing the grease on the outlet, whenever it starts looking clean you stop pumping.
- After you are done greasing all inlets, do not put the bolts back to the outlets, do a small routine which moves all robot's axis atleast 60°, this is to let the air trapped inside to go out, after running the routing for around 5 minutes, you can put the bolts on the outlets back without problem.
- As for bearing greasing, we use a syring on the small inlets, and just keep inserting until it throws it back.
It is a very raw explanation, but atleast you can get an idea how it is usually done. -
The kit that you can order from Lincoln will have diagrams that show the exact position the arm should be in to grease the various axis. It also includes 2 small syringes for where there are no fittings.
It will also show you where each inlet, and out for each axis are located. As far as backup goes, we back up every time A new program is loaded, or created. Just tell them what arm you have to get the
right instructions, they will send pages from that arms manual. -
- After replacing the batteries, we do a backup, All of Above backup and Image backup.
I would always do the backups before starting, especially changing the batteries!
To get advice more relevant to your robots, post the model(s) you have.

I plan on calling in fanuc for it, i just need to set a time line and everything, my biggest problem is my fanuc only runs 2.5-3 weeks a month on one shift. so im trying to figure out when to have them pm based off of that.

Ah, yes. Totally skipped that part. But yeah, do back ups before starting the whole maintenance process.
-
The exception to doing the backups before the batteries are instances where the batteries are already dead, in which case cycling power for an image backup may be wise to wait until the batteries are replaced.

We have A p-50iB robot and i'm curious to if anyone knows much about where to get a maintenance kit for one.
-
If it is a paint robot (which is is since it's a P-50), Fanuc America is the go to choice if you don't know what to order. Once you know what order, use google.
