CNC Myford S7 Lathe - Cutting Left-Hand thread M19*1.75mm

Hi
Back to the threading!
This example shows a left-handed thread being machined (M19*1.75mm). As you can see, it works just as well for left-hand threads as it does for right-hand ones. Again, virtually any pitch thread can be machined easily. It might be worth noting that, if a thread milling or grinding attachment were to be added to the lathe, then even greater accuracy could be achieved as well as being able to produce large diameter threads.
There is no undercut provided at the start of the thread in this example, although, tougher steels may require one. I was using EN3B.
Take a look at some of my other channel videos for further information on my CNC Kit that has been added to this 1969 Myford Super 7 lathe.

Thanks for taking a look at my video
