UR5e wrist 3 replacement

Hello everyone,

I have a UR5e robot which I’m using for machine tending applications. To be more specific, the robot is responsible for the process of loading and unloading parts from a CNC machine. I had some issues with wrist 3 (the one near the tool flange) since the robot is permanently exposed to emulsion and swarf (CNC chips). I disassembled the robot’s wrist and took it to a service shop. I was told that the wrist’s bearings were very worn. Long story short, they sent me back the wrist and they said it is functional now. I did install it back on the robot and followed the instructions from the manual. However, my question is the following one. Do I must do anything specific such as calibration, joint zeroing or reconfigure the features/plans within my program? I hope all of these things are not necessarily since it would be a total headache. Like I said previously, the wrist was installed back on the robot and the robot’s movement is good.

Thank you,

Victor.

It is recommended to have the robot recalibrated (dual robot calibration) when replacing a joint, but it’s often fine not to do it.

You might have to adjust positions in the program, though, but you won’t know this before you run the program.

What about a software update? Is that necessarily if you replace a joint?

No. It could be on really old robots (<2012), but not the e-series.
