Numerical control five-axis machining center is a kind of high-tech processing equipment, mainly used for processing complex curved surfaces. It has five axis linkage, which can process various irregular shapes of parts in an all-round way and with high precision. The high-precision machining of numerical control five-axis machining center is mainly realized through the following aspects: Error synthesis method: By measuring the original errors of each axis of the machine tool, and using high-precision measuring instruments such as laser interferometer, after synthesizing the errors, measures are taken to eliminate or reduce these factors. Error Transfer Method: By transferring the geometric errors, force deformation and thermal deformation of the process system, etc., so that it does not affect the processing accuracy. For example, using a fixture to transfer the original error of the machine tool spindle to the aspect that does not affect the machining accuracy. Error Average Method: Using the mutual comparison and mutual correction between closely related surfaces, or using each other as a reference for machining, in order to achieve the purpose of eliminating machining errors. Direct Reduction of Original Error Method: After identifying the main original error factors that affect machining accuracy, try to directly eliminate or reduce them. For example, using the large feed reverse turning method, the bending deformation caused by axial cutting force is basically eliminated. The above measures have significantly improved the machining accuracy of the numerical control five-axis machining center. For more information, it is recommended to consult a professional.
