Hello there again,
I think I got all the possible unluck with this Kitamura machine.
I am not sure if this happened to someone before m I personally never heard of it...
After running the machine 10 hours yesterday, and fixing another issue thanks to the help of this forum, today I have run 1st part, fine second part then I heard one of those noises you don't want to hear, run to the machine, stopped it, and then realize spindle was spinning but the tool wasn't clamped properly.
I haven't really noticed any dent on either vise/spindle nose, the 6mm end mill snapped, I am "glad" this happened with this tool, as the tool before that one, on the program is a 3" shell mill, I have used the same tool holders before many times, even on more "heavy-duty" work, never had any problems.
I think there is only 1 drawbar gripper left.
I think I am getting all the possible unluck with this machine as it has been 1 year of nonstop problems.
It seems there are no scratches on the spindle taper either, I checked with the tenth clock spindle taper, and run out seems to be less than 1 micron, however, if I push the spindle nose from the side there is a 0.002mm play, not sure about this.
I will have to call the engineer in again, do you know what could have caused the drawbar grippers to snap? Drawbar tension?
Spindle has been refurbished and refit 2 weeks ago
