Description

Technical Field

[0001] This utility model mainly relates to the field of five-axis linkage machine tool, specifically to a five-axis machine tool and a cement foundation. Background Technology

[0002] Five-axis machine tools play a crucial role in high-end manufacturing industries such as aerospace, precision molds, automobiles, and energy equipment because they can achieve efficient and high-precision machining of complex spatial curved surfaces.

[0003] With the increasing demands for machining accuracy and efficiency, the dynamic performance (such as stability and vibration resistance under high-speed motion) and the maintenance of geometric accuracy during long-term operation of five-axis machine tools have become key limiting factors. Vibrations generated during machining (including spindle rotation vibration, vibration caused by feed motion, and vibration from cutting forces) directly affect the quality of the machined surface (such as surface roughness and waviness), dimensional accuracy, and shape accuracy, and may even lead to accelerated tool wear or chipping. Simultaneously, environmental vibrations (such as the operation of nearby equipment and ground traffic) can also be transmitted to the machine tool through the foundation, interfering with the machining process.

[0004] Ordinary concrete has relatively limited damping performance (vibration absorption capacity), and its attenuation effect on medium and high frequency vibrations (especially vibrations generated inside the machine tool) is not ideal. At the same time, the five-axis machine tool and the worktable are installed on the top of the same cement base, and interference will occur between them during operation, which will have a secondary impact on the machining accuracy of the workpiece.

[0005] It should be noted that the above content falls within the scope of the technical knowledge of the utility model owner. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content
