Q

If your machine is equipped with stop pins, they are merely a guideline to placement

A

Nope, put that sucker tight against them, they are not just for show

20
Q

An universal truth about CNC machinery they tried to hide on the last page

A

They all use a computer to direct the tooling (hence COMPUTER numeric control) and have way better speed, accuracy, repeatability, and productivity compared to other machinery and people, AI is coming for us babes
