I have 2 issues with my tool changes and tool holding.
1. After a tool spends a significant amount of time in the spindle being used it makes a loud "pop" when it is changed and returned to the turret. It seems like excessive air pressure builds behind it during use. This also happens if the machine is completely off over night and the air is shut off to the machine. The first tool change results in a big "pop" sound like too much air behind the tool in the spindle.
2. Recently the machine began sounding like something internally is shorting out during tool changes. Sometimes after the machine is shut down it will not do it during the next use, but it seems to be getting more common. See video and listen to the sound during the tool change.
Any suggestions are appreciated. Thanks.
