High-precision numerical control machine tool

Abstract

The invention relates to the technical field of numerical control machine tools, in particular to a high-precision numerical control machine tool comprising an integrated portal frame. The integrated portal frame comprises a body. The body is provided with a cross beam portion and two supporting leg portions. The cross beam portion is provided with an upper supporting table, a lower supporting table, a motor seat, a main end bearing seat and a tail end bearing seat, wherein the upper supporting table and the lower supporting table are provided with an upper sliding rail portion and a lower sliding rail portion correspondingly, the upper supporting table and the lower supporting table extend in the horizontal direction, a plurality of rib portions shaped like the Chinese character 'mi' are arranged between the upper supporting table and the lower supporting table side by side, every two adjacent rib portions shaped like the Chinese character 'mi' are mutually connected, and a reinforcing rib extending vertically is arranged between every two adjacent rib portions shaped like the Chinese character 'mi'. The motor seat, the main end bearing seat and the tail end bearing seat are provided with installation holes correspondingly. Each supporting leg portion comprises a hollowed portion and a leg portion, wherein the hollowed portion comprises two portions shaped like the Chinese character 'mi', the two portions shaped like the Chinese character 'mi' are parallel to each other, and a connecting rib is arranged between the two portions shaped like the Chinese character 'mi'. The high-precision numerical control machine tool can absorb certain vibration, reduce the influence of the vibration on machining precision and improve the machining precision.
