Description

Technical Field

[0002] A CNC milling machine, also known as a CNC milling machine, means a milling machine controlled by digital signals of an electronic computer. A CNC milling machine is an automatic processing device developed on the basis of a general milling machine. The processing technologies of the two are basically the same, and the structures are also somewhat similar. CNC milling machines are divided into two categories: those without a tool magazine and those with a tool magazine. Among them, the CNC milling machine with a tool magazine is also called a machining center.

[0003] With the development of science and technology and the rise and continuous maturity of the world's advanced manufacturing technologies, higher requirements are put forward for numerical control processing technologies. The application of technologies such as ultra-high-speed cutting and ultra-precision machining puts forward higher performance indicators for the numerical control system, servo performance, spindle drive, and machine tool structure of CNC machine tools. At present, when machining multi-face parts, it is necessary to manually flip the workpiece. Such an operation method is not only more cumbersome but also requires repositioning, thus seriously reducing the use effect of the CNC multi-face machining device. For this reason, we propose a CNC multi-face machining device with a flipping structure to solve the above problems. Content of the Utility Model
