What is the difference between a manual and a CNC lathe machine?
A manual lathe uses electricity while a CNC lathe does not.
The main difference is that a manual lathe is operated by hand, while a CNC lathe is automated and controlled by computer programming.
Manual lathes are faster than CNC lathes in production.
CNC lathes are only used for small parts, while manual lathes can handle larger pieces.
