Description

Technical Field

[0001] The present invention relates to the technical field of precision machining of machine tools, and particularly relates to a precision machine tool integrating turning and milling. Background Art

[0002] During the processing of energetic special materials, due to the particularity of the materials themselves and the strict requirements of the processing environment, the processing equipment needs to be operated inside a sealed glove box. However, the limited space of the glove box poses new requirements for the volume and functions of the processing equipment.

[0003] Currently, the machine tools used for processing energetic special materials usually can only achieve a single processing function, such as only being able to perform one of rough milling, finish milling or turning. For workpieces that require multiple processes, the operator has to transfer the workpiece between different devices multiple times, which not only increases the operation complexity but also significantly reduces the processing efficiency. In addition, due to the limited internal space of the glove box, traditional machine tools often cannot take into account the integration of multiple functions while meeting the volume requirements, resulting in low processing efficiency and increased costs.

[0004] In the prior art, although there are some multi-functional composite machine tools, these devices are usually large in volume and cannot meet the requirements of the narrow space of the glove box. At the same time, due to the high requirements for precision and stability in the processing of energetic special materials, traditional composite machine tools also have deficiencies in function switching and precision maintenance. Therefore, developing a machine tool that can achieve multi-functional integration within a limited space and at the same time meet the high-precision processing requirements has become an urgent technical problem to be solved in the current field of processing energetic special materials.

[0035] The technical features not disclosed in this embodiment are the same as those in Specific Embodiment 1.

[0036] In this embodiment, the servo motor 12 drives the ball screw 14 to rotate through the coupling 13, thereby driving the X-direction movement of the lathe X-axis moving platform 81 and the Z-direction movement of the turning and milling machine Z-axis moving platform 91.

[0037] When turning processing is carried out, the workpiece is adsorbed and fixed on the lathe spindle module 11 by the lathe vacuum chuck 7 (vacuum degree -90 kPa).
