I've been working to diagnose an intermittent chatter that our operator has been mentioning.

PUMA 10HC
Ser # PH100157

Upon inspection I found there to be a lot of play in the z-axis slide's y direction (up/down). I removed the wipers, hoping to find a gib screw to adjust the clearance but the only adjustment is for the z direction.

Looking more closely, I found the problem. The plastic friction material that the turret rides on in the carriage has been pushed out the top of the spindle side of the slide, see picture.



I'm at a loss as to what to call this stuff and where to get it. I do have a parts manual but the drawings are not very clear.

Anyone who knows what to call this stuff and/or where to get it would be appreciated
