How long do milling apprentices usually study?

More than a year. Milling workers are skilled workers who process parts with milling machines (equipment for processing parts) according to the design drawings of parts, and are divided into junior workers, intermediate workers and senior workers. As an apprentice of milling machine, you need to know the basic knowledge of machine tools, including components, working principle, operating procedures, maintenance and so on. Apprentices should understand the functions and mutual cooperation of various parts of the machine tool through basic training such as drawing, parts processing and assembly. It is important to be familiar with the structure of milling machine. The structure of milling machine is not only the carrier of work, but also determines the different processing methods of workpiece. Therefore, apprentices of milling machines need to know the components, structural forms and working principles of milling machines in order to better carry out processing operations. Milling apprentices generally study for more than one year, and if they have high understanding, their study time will be shortened. We need not only theoretical study, but also practical study. It is very important to be familiar with the types and usage of common milling cutters. Because different milling cutters have different characteristics when processing different materials, it is necessary to select the appropriate milling cutter for processing according to different workpieces. Milling is one of the basic operations of milling machine. Apprentices need to master standardized milling operation flow, fixing and clamping methods of parts, and operating skills of milling machines. In addition, we need to know how to mill parts with different shapes and how to control the tolerance of size and shape during machining.
