Analyze the changing concept of turning and milling combined machining

　　In order to win in the fierce market competition, the integration of the added value functions of the turning-milling compound machine tool is developing. Representing this trend is the use of one machine tool for compound processing and different methods of processing, as the trump card of the era of production that can achieve multi-variety, small-batch production, and different varieties and different yields. More than half of the original machining centers and CNC lathes will be replaced by turning-milling compound machine tools, which is expected to achieve a production and sales scale comparable to all machining centers.

　　The changing concept of turning and milling machine tools

　　 Today's manufacturing industry, especially in the machining site, has the following characteristics. ①Multi-variety, small-batch production ②Short delivery time ③Reduce cost ④Products with complex shapes are added with lighter weight and performance compound ⑤Lack of skilled operators and skilled personnel. In order to adapt to this status quo, it succeeded in the fierce market competition and appeared as a compound processing machine tool.

　　A machine that has several processes and different processing capabilities for processing complex-shaped workpieces is called a compound processing machine. In order to achieve the same purpose, there are also ways to use multi-axis control coordinates, expand processing functions, and multi-function. In short, the method of process integration is used to improve production efficiency and increase the added value of machine tools. Therefore, here, the former machine tool that realizes different types of processing in one machine and the latter's multi-coordinate control machine tool are generally called compound processing machine tools.

　　 The functions of the turning-milling compound machine tool have changed with the changes of the times. In the past there was a period when the machining center was called a compound processing machine tool. However, due to the limitation of the types of tool exchange processing and the inability to go out of the field of cutting processing, the general machining center is no longer called a compound processing machine tool. . Similarly, the era when the current compound machining machine is no longer called a compound machining machine may not be far away.

　　 The development and production of turning-milling composite machine tools are continuously advancing, and the number of sales of machine tools that combine turning functions and rotary cutting functions is rapidly increasing. In the future, it is expected to reach a production and sales scale comparable to machining centers.

　　At the beginning, Japanese compound processing machine tools were based on lathes, with milling functions and enhanced. This is because almost all workpieces processed by lathes must undergo secondary milling and hole processing. The compound processing machine tool was originally developed for the purpose of synthesizing these processing procedures.

　　 However, the recent turning and milling compound machine tools have changed from the original turning process to the milling process, instead of machining centers.
