Machine is a 94 VF-1. I bought it used and havent tried using the rigid tap untill now. The processor went bad and we had to install a new processor & board so it lost all the parameter settings and such.
When i tap with it, you get 3 or 4 good parts then all of a sudden it will break the tap while tapping. Whats happening is the spindle and feedrate arent staying 100% in sync with eachother. It varys just enough to snap the tap. Im thinking there is a parameter setting somewhere that has to do with keeping them in sync with eachother. But i dont have the manual for this machine, and the manuals we do have are for 96 and newer machines and dont explain the paramater settings.
Any suggestions apreciated.
