We didn't want to put guarding around the machine, and we were told the robots would work well in the application. Now we are told that the coolant is a problem, and it doesn't appear that UR robots has a coolant sleeve solution for the robot that doesn't wrap up. It appears their customer service doesn't have a headquarters shop where they can repair robots either because they are not offering a US headquarters based solution but are instead suggesting distributors handle the repairs for them- when in this case the robot was sold by a customer of a distributor so essentially there may not be a customer service party to address the repairs?. The UR robot is seeming like a toy robot advertised to be an industrial robot.

I think industrial in this industry is a definition that means long term durable, and this product doesn't seem to belong in that category.

No the product does not belong in that category.

If you do make a change from the UR you could look into area scanners/an area scanner to protect the robot zone instead of guarding. Depending on how your safety team evaluates it, but their are plenty out ther like that.

I wonder how is the coolant hitting the robot, Are you flushing the fixture or part as the robot picks it?

When we do machine tending applications yes some coolant gets to the arm, but not to much unless the part needs to path above the arm and coolant from the part drips down into it.

Coolant and chips are always the unknown variable for us to manage. Its a pain sometimes.
