I have a Haas Super Mini mill, and the tool changer clip is delaying a bit at the end.
In the process of diagnosing the problem I discovered that it even happens when there is no tool in the spindle.
I did clean the draw bar on the top with some scotch bright, and then cleaned it real well and applied a little of oil, but the delay still happens on about every 2nd or 3rd activating of the clip.
I did discover that I had excessive moisture in my compressor tank ( I've fixed that issue.... but there is a good chance that there was moist air entering into the draw bar system )
I have attached a link to a short video showing a close up of what's happening.
Any thoughts or suggestions?
