Hello,
I am continually getting a Tool Unclamp Alarm 247 on my Mazak 510C II. I can reset the ATC arm and we are monitoring the clamp and unclamp of the drawbar itself in manual mode and it seems to work great.
I have run the Tool change in MDI mode and the same alarm will pop up.
I have run the Tool change in MDI mode with-out tools in the spindle or "on-deck" pocket and the same alarm will pop up.
It is intermittent and I am suspecting the hydraulic valve is going to puke.
Any other thoughts? I will be pulling up the manual to determine if there is a drawbar finger / spring replacement I should be doing also.
Thanks in advance.
