Five-axis machining center is also used in civil fields such as wood mold manufacturing, bathroom trimming, automotive interior parts processing, etc., and the following factors should be considered when choosing:
1. Structure
The five-axis machining center has a variety of structures, the structural design of the machine tool determines the performance of the equipment from the basis, determines the rigidity, machining accuracy, stability, operability, etc. of the machine tool, and pays attention to the selection of whether the linear axis is not merged and superimposed when moving, the rigidity of the equipment with a short cutting loop, the motor used in the inclined rotary axis, whether it is the five-axis linkage, the proximity of the five axes, etc.
2. Accuracy of inclined axis of rotation
The machining accuracy of the machining center is directly affected by the accuracy of the rotary axis, and the higher the accuracy, the smaller the machining error.
3. Interference and collision avoidance
Interference collision avoidance is a problem that cannot be ignored in 5-axis machining, in addition to the use of computer software interference checking, a good 5-axis machining center also has the function of manual mode to prevent interference, and can check in advance for possible tooling errors or tool length setting errors before machining, so as to reduce the emergency stop in operation to a minimum.
4. Rotation center correction
The change of the rotation center caused by changes in the environment and temperature will affect the accuracy of the 5-axis machining, and it should be automatically corrected by the probe, and the 3-axis/indexing/5-axis machining accuracy verification machining should be processed, and the tool connection error should be <±4μm.
5. Linkage accuracy
The linkage accuracy of a five-axis machining center is the result of multiple factors, including processing equipment, workpiece material, workpiece size, tool used, etc.
6. Process support
The machining process of the 5-axis machining center determines whether the performance of the equipment can be maximized. For example, the use of special-shaped tools can greatly improve the processing efficiency.
