Learn a small grinder and find a job later. No, what is the difference between a small mill and a grinder?

What kind of small grinder are you talking about? There are internal and external grinding machines, surface grinding, centerless grinding, tool grinding and so on! Look what you've learned! Generally speaking, the job of grinder is still very easy to find! But small grinders are not as good as large and medium grinders after all! Although the operability of small grinders and large and medium-sized grinders is basically the same, there are differences! You have studied, but you may not be able to do large and medium-sized ones! I recommend you to learn a medium size! Medium operability is basically the same as others! I hope I can help you solve it. I wish you a good journey!
