Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, and particularly relates to a turning and drilling compound machine tool for graphite processing. Background Technique

[0002] In modern manufacturing, graphite, as a high-performance non-metallic material, is widely used in the fields of electronics, metallurgy, machinery, chemical engineering, etc. due to its unique physical and chemical properties, such as high melting point, high hardness, good thermal stability and chemical stability, as well as excellent electrical and thermal conductivity;

[0003] In the processing of graphite materials, turning and drilling are two common processing methods. Turning processing is mainly used to remove the excess parts of graphite materials to obtain the required shape and size; while drilling processing is used to form specific holes in graphite materials to meet specific functional requirements. However, in current processing technologies, these two processing methods usually require the use of different equipment - a lathe and a drill press, for separate processing. The graphite material needs to be transferred between the two devices, which may cause damage to the material or a decrease in accuracy during the transfer process, reducing the processing efficiency. In view of this, a turning and drilling compound machine tool for graphite processing is proposed. Content of the Utility Model
