Fanuc G76 screw cutting Cycle

Hi everyone,

I am currently looking at purchasing a CNC Lathe for a screw cutting
application.

I understand that there are special G7? instructions for screw cutting on
the Fanuc OTA controller.

Having searched everywhere for details of these I have now given up.

Can anyone help me, by sending me details of the codes.

I wish to test any machine before purchase, to ensure I can do screw
threading automatically.

The machine I am currently considering is a Colchester 2000 L with a Fanuc
Ota controller.

We need to thread lengths of Monal metal between centres (6 inch lengths
approx)

Then take out the thread from the centre with a button tool.

Thanks for your help.

Regards

Mark
