haas tool changer

[petey]

my tool changer is mal-functioning , tool does not release from spindle , I wrote a small program to preform 10 tool changes

but I want it to automatically when it gets to the end of the program to restart so I can run the program for 30 minutes, I tried using m01 , m02 and m30 non worked even with they optonal stop off,is there a special code you use for this particallur machine , Haas TM3 vertical mill. if this is a improper question to post then please disreguard as I am new to this forum thaks petey.

Okay will it release the tool manually? You might just have a dirty spindle taper.

 

Wait I dont think I understan what you are trying to accomplish is a tool Stuck in the spindle, like it wont release? If so hold it with one one hand have someone press the release button and give it a few taps with a brass hammer.

I am way way far from being a g-code genius like many on this forum but I don't think you'll be able to get the program to restart automatically...

 

I would make your existing program into a sub-program and call up a bunch of repeats...

 

P.S. Welcome to the forum

ohhhhhhh loop it in a subprogram?

just change your M30 to M99 and it will run indefinetily until you stop it.

I used to have similar problems on a Haas and Fadal especially when the machines were doing heavy roughing.. To fix the problem I would clean the tool holders and spindle then apply a light coat of synthetic oil to the tool holders. Also taking the tool out at the end of the day so it does not sit in the spindle all night helps. As mold100 mentioned tapping lightly with a brass hammer can get a tool to release that is stuck. I know this does not answer your question directly but these suggestions may make your tool changer function properly.

put a little oil on grease on the tapers if there dry.sometimes they will taper lock when the machine warms up or after working the machine hard.

haas spindles use the coolant to cool it, if you do heavy roughing or cutting with a tool that is cutting dry it will also cause the tool to stick
