The structural forms of five-axis machining centers are diverse. They mainly achieve complex curved surface processing through the combination of three linear axes, namely X, Y, and Z, and two rotational axes. Their mechanical design directly affects the processing flexibility and accuracy.
Double swing head structure : Both rotating axes are integrated on the spindle head, directly controlling the direction of the tool axis. It can achieve swing within an inclination range of ±120°, suitable for efficient processing of spatial curved surfaces, and is commonly found in vertical five-axis machining centers.
Double turntable structure : All the rotating axes are set on the worktable, and the posture is adjusted by the rotation of the workpiece. The structure has high rigidity and is suitable for processing large workpieces. It is typically applied in gantry-type five-axis machining centers, such as the design of a gantry frame with a moving crossbeam.
One-swivel structure : One rotating axis acts on the tool (such as the swivel head), and the other acts on the workpiece (such as the turntable), combining the advantages of double swivel heads and double turntables, and can flexibly adapt to the requirements of turning and milling compound or multi-angle processing.
Pendant structure : It includes pendant swing head type (the rotation axis is not perpendicular to the linear axis) and pendant worktable type. The structure is simplified by tilting the spindle or worktable, but the numerical control system is required to compensate for the offset of the tool tip point trajectory. It is suitable for specific Angle processing scenarios.
Composite structures : such as cradle type, vertical and horizontal conversion type, etc., expand the application range by integrating functions such as turning and milling. For example, the combination of a cradle turntable and a ram structure enables integrated turning and milling processing.
