What exactly does an ordinary lathe worker do?

Turning is a method of machining with lathe. Lathe is mainly used to process all kinds of revolving surfaces, such as inner and outer cylindrical surfaces, conical surfaces, forming revolving surfaces and end faces. Lathes can also process threaded surfaces. If the hole processing tools (such as drill, reamer, etc. ), the inner circular surface can also be processed. Lathes account for the largest proportion of metal cutting machines in general machine tool plants, accounting for about 40% of the total number of machine tools. There are many kinds of lathes, which can be divided into horizontal lathes, vertical lathes, turret lathes, multi-tool lathes, copying lathes, single-axis longitudinal cutting automatic lathes, multi-axis bar automatic lathes and so on. In addition, there are crankshafts, A-axis lathes, shovel lathes and other lathes. Among all kinds of lathes, the common lathe is the most widely used universal machine tool, and its transmission and structure are also very typical. Therefore, this chapter mainly analyzes the common lathe cA6 140, and learns the general method of analyzing machine tools. Almost all kinds of general machine tools have their corresponding CNC machine tools, and the requirements of the two types of machine tools are also different. CNC lathe is a widely used CNC machine tool at present.
