I don't think it's necessary to be an apprentice in your situation. You were absolutely right to go to the last training class. The programming of CNC lathe is very simple, you only need to know the programming code and principle systematically, and you can master it quickly with your lathe work experience. Many people who have just graduated from CNC lathes can't find jobs, not because they haven't studied, but because they have no lathe work experience and poor hands-on ability. After all, you have six years of lathe work experience, and you only need to systematically learn the theoretical knowledge of CNC lathe programming, and you will soon be able to master CNC lathes skillfully. Don't know where to study. I suggest you go to the field and see for yourself. First of all, it depends on the proportion of teachers and equipment and students in this training course, as well as the age of teachers and the history of running training courses. Don't believe the nonsense of the admissions teacher. You asked the master to take you there. He didn't teach you the basics of lathe work. You have to do a lot of work for him. As a master, you should know how the apprentice learned it, right?
