The invention relates to the technical field of numerical control planer type milling machines, in particular to a high-accuracy product processing method for a numerical control planer type milling machine. The method comprises the following steps of: 1, processing a reference: processing a lateral reference surface; 2, replacing / rotating an accessory head: replacing / rotating the accessory head for a hole I; 3, mounting an edge finder: mounting the edge finder on the accessory head; 4, executing processing of the reference: executing a measuring procedure for a positioning surface to measure the positioning surface; 5, automatically compensating data of a milling head, wherein the accuracy of the relative position of the hole I and the reference surface is guaranteed; and 6, continuously processing through the main procedures: continuously processing a hole II and a hole III through the main processing procedures 2-5. In the high-accuracy product processing method for the numerical control planer type milling machine, the edge finder and related software are additionally provided; during processing, the edge or the center of the reference is found by using the edge finder each time after the accessory head is replaced or rotated; and the current state of an accessory is subjected to coordinate compensation through the software, so that extremely high accuracy required by the position is achieved.
Description
technical field [0001] The invention relates to a processing method, in particular to a processing method for high-precision products of a numerical control gantry milling machine. Background technique [0002] The CNC gantry milling machine must use the attachment head for five-face machining. The attachment head is often replaced and rotated. Its accuracy is greatly affected by the meshing accuracy between the end face of the ram and the positioning surface of the attachment head. There are also tolerances in the manufacture of the attachment head. Therefore, in the process of product processing, Due to the replacement or rotation of the attachment head, the relative position and size are unstable, and the replacement is inconvenient, which reduces the production efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is: due to the replacement or rotation of the attachment head, the relative position and size are unstab...
