Dear masters..
How can I cut a large diameter thread (female and male) on a mini milling machine?
Tools?
Steps?
Methods?
Pictures?
Thanks a lot

Single point thread milling.
Mach 3 does it and you can make your own cutter or buy a insert and make a holder.
Youtube has a few videos.
Thank Arizonavideo,
My machine is not CNC. Its a manual machine similar to harbour frieght.
What is larger?
For a mill you can buy a tap or find a lathe if the part can be mounted on a lathe.
Their my be a way to make a jig to allow you cut a known pitch on a round stock but I have not seen one.
Large like 60mm diameter. Any thread type will do because I will do the same for the male and female side. I dont have a lathe machine and no tap that size.
Form tools or jig? I have not seen one too.
Do some research on Joseph Brown of Brown & Sharpe and his universal milling machine.

Basically you need some kind of gearing between a rotary table/indexer and one of the slides, probably the Z axis.
In Brown's time that gearing had to be mechanical and in some cases it could get very complicated (variable length drive shafts, universal joints etc.) but today it would be a lot simpler to put a servo/stepper motor on the rotary table and the Z axis and do the gearing in a computer.
Thanks all,
I guess its either electonic control (CNC) or motorise the z axis and rotary table. Otherwise it is too complicated.
