Description

Technical Field

[0001] The utility model relates to the field of machining machine tools, specifically to the field of turning and milling machining, and in particular to a multi-station multi-axis machining center. Background Art

[0002] Milling and turning machining centers are highly integrated, multifunctional, high-precision, and automated CNC machining equipment. They are widely used in automotive, aerospace, electronic equipment, and machinery manufacturing, and can meet the processing needs of complex parts. While single-station milling and turning machining centers have certain applications in the mechanical processing field, they have some significant drawbacks, as follows:

[0003] (1) Low production efficiency: A single processing station means that only one workpiece can be processed at the same time, which limits the production capacity of the machining center; when a large number of workpieces need to be processed, a single-station machining center may require a longer processing cycle, thereby reducing overall production efficiency.

[0004] (2) Limited flexibility: A turning and milling machining center with a single machining station may need to frequently change tools and tooling when machining different workpieces or performing different processes, which increases the complexity and time of machining preparation; limited flexibility is also reflected in the difficulty in processing multiple types of workpieces at the same time or performing multiple processes at the same time.

[0005] (3) Low equipment utilization: In single-station processing mode, the equipment may be idle while waiting for tool change, workpiece replacement, or other preparatory work, resulting in low equipment utilization. This not only reduces processing efficiency but also increases equipment operating and maintenance costs.

[0006] (4) Limited scalability: Single-station milling and turning machining centers have limited scalability. For example, it is difficult to add additional machining stations or specific functional modules to improve production efficiency and processing capacity. This limits the possible upgrades and expansions of the machining center in the future, making it difficult to adapt to changing market demands and process requirements.

[0007] In summary, the turning and milling machining center with a single processing station has certain defects in production efficiency, flexibility, equipment utilization, and scalability. Utility Model Content
