When I do a tool change on my vf-2 it makes sort of a popping noise. Any ideas or solutions?

Sounds like the tool release mechanism in the spindle. My tm-1 will do this
if things get a little dry, sticky, rusty up in there. Try the following...
1.) Spray some wd-40 or the like up into the spindle using the the long red nozzle included on the can. Then do a couple of manual tool changes. Spray some on the pull stud also and into the spindle each time. This usually loosens things up after a few times. To oil it up good I sometime hold the tool release button and float the tool on the air pressure coming out of the spindle to try and force some of the wd-40 furthur up into the spindle. I sometime do this before and after I use the machine. I also leave one of my tools in the spindle if I leave the machine for a long time.
2.) Make sure your compressed air is dry. Make sure you not getting water in the air line.
Water in this area may cause some rust to form.
have you noticed it only happens when the tool has been in the spindle a long time..like over night? if you put the next tool in the pop doesnt happen any more....right?
if so the tech told me that the solution is to not leave the tool in the spindle over night or when not in use...
I dont know if it is pressure build up or just a suction fit because the tool gets "sealed" in that taper contact...because that is a lot of surface area!
hope that helps

We have a new TM-2 that is only 6 months old. It started doing the same thing as you described. Haas tech came to install new mocom board and noticed the poping sound. He said that it was from a dry pull knob. He recomended that i keep the bore and tool clean and keep the pull knob greased. i've followed his advice and have not had any poping. I also think that some coolant may wick up between tool holder and bore. I make it a habit to wipe down all tool holders and the bore after running a job and haven't had any problem.
