Who can tell me where I can get a grinding machine mechanic's license and what are the ways to get it?

Hello, there are generally two ways: one is to register with the local labor department, and it is best to attend one of their trainings; The other is to register in a local technical school or professional school with great influence. The advantage of registering here is that it is more convenient. I can give you some information when appropriate. The disadvantage is that the price may be high. Good luck!
