Does anyone have a sample program for a Miyano BNC-12S that is utilizing the main and sub spindles including pick off?
We have this machine that they want me to get going. I read the book and got the main doing a bar feed, turning, grooving, and cut off. But the book is less helpful for the sub spindle. The operation command and then the B axis start after that? Weird.
Also, will we be able to pick up, pull out partway, turn on main (still connected), pull more, turn, etc... then re-pick up closer and cut off?
Thanks

WARNING: this is NOT for your machine! This is g-code used on a Mazak but I think it is reasonably generic and might still be of use when compared to your manual.

does the machine have a Fanuc control or some weirdo non-standard thing?

Maybe this will help. It's for a BNC-34S, but the code should be identical.

Hi folks, I have a problem with the threading cycle control of a lathe with SINUMERIK 810 T, the problem is this, when I start the cycle is poised to start with threading passes but remains in that position and the cycle begins , the funny thing is I do it my way SKB does, do I program the internal thread to run smoothly, the problem has to do only external thread, the failure started suddenly after making more than 2000 threads. From already thank you very much and sorry for English.
