Hi All

Anyone been able to cut left hand threads on an Orac cnc ?

Marcus

I cant see why it would not be possible.

The thread routine would have to cut from the chuck towards the tailstock to keep the spindle direction the same and use the same tool.

Quick Turn 2D writes threading routines this way for LH threads.

Hi Steve

Thanks for your reply.
I should have added "using the original programming method", the threaading cycle G33 doesn't give provision to thread from the chuck to tailstock,
also no G95 available to just do a cylic program.

I wanted to use the Orac for this job but will have to run it on my Compact 5 cnc which will do LH threads as standard programming.
