me. What are you going to do? Roland also asked him to bring three blacksmiths and their respective apprentices to learn the use of milling machines in the yard. It is impossible for him to personally operate these machine tools every day, so he must train a group of professional workers. After everyone gave their salutes respectfully, Roland began to demonstrate how to use a milling machine to machine gears. He didn’t mind being a senior fitter in front of everyone.

Whether it is a steam engine or a machine tool, there will be no such thing as a phenomenon that shops are scrambling t
