Precision CNC machining for the processing of more parts, according to its structural characteristics of the processing part into several parts such as endomorphic, shape, surface or plane. Generally, first processing plane, positioning surface, and then processing hole; first processing simple geometry, and then processing complex geometry; first processing low precision parts, and then processing strong precision parts.
To rough and finish machining sub-sequence method. According to the processing accuracy, stiffness, deformation and other factors of the parts, can be divided according to the principle of separation of roughing and finishing, that is, first preliminary machining and then finishing, and then can use different machine tools or tools for processing; for easy deformation of the parts, must be calibrated, because the deformation may occur after the preliminary machining. Therefore, in general, any parts that require roughing and finishing should be separated.
Precision CNC non-standard parts processing generally selects the stamping process for products with sheet metal as the key raw material. Some choose the casting process and then cut the blank. Products are generally installed after surface treatment. Small hardware products with plastic as the raw material, choose extrusion, injection molding, blow molding, combing or surface treatment.
