Division of the processing stage of the machining center

For processing on a machining center, the division of the processing stage is mainly determined according to the accuracy requirements of the workpiece, and also needs to consider factors such as production batch size, blank quality, and processing conditions of the machining center.

(1) If the part has been roughed, the machining center only completes the final finishing after *, so there is no need to divide the processing stage.

(2) When the machining accuracy of the parts is high and the rough machining has not been carried out before the machining center, the rough machining and finishing should be carried out separately. Rough machining is usually carried out on ordinary machine tools, and only fine finishing is carried out on the machining center. Processing. This can not only give full play to the functions of various machine tools, reduce processing costs, and improve economic benefits. It can also allow parts to have a natural aging process after rough machining, eliminate residual stress generated by batch processing, and restore cutting force and clamping force For the elastic deformation caused by the cutting heat and the thermal deformation caused by the cutting heat, artificial aging can be arranged when necessary, and various deformations can be eliminated by finishing processing to ensure the machining accuracy of the parts.

(3) The requirements for the machining accuracy of the parts are not high, and the quality of the blanks is high, the machining allowance is not large, and the production batch is small. The good cooling system of the machining center can be used on the machining center to remove the rough and static parts. The processing is combined to complete the entire content of the processing procedure, but the rough and finishing processing should be divided into two procedures to be completed separately. In the process of processing, for parts with poor rigidity, corresponding technological measures can be taken, such as arranging a pause command after roughing, and the operator will slightly relax the clamping elements (devices) such as the pressure plate to restore the elastic deformation of the parts. Then use a smaller clamping force to clamp the parts, and then perform finishing.
