What happens here
The group then visits a manual grinder, which is one of Rottler's last manual machines still in use. This machine is used to grind highly precise spindles for large format machines, like the F80 series for big diesel engines. The attention to detail includes tracking each dimension of every spindle throughout its assembly to ensure compatibility with various tooling, including custom-made right-angle drives.
Goal: Showcase manual precision grinding for machine spindles
