Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a column of a numerical control machine tool. Background Art

[0002] The column of CNC machine tools is one of the important parts of CNC machine tools. Its main function is to support and fix the workbench and saddle of the machine tool. It also provides a stable working posture and machining accuracy for the machine tool. The structure, material, and processing technology of the column of CNC machine tools will directly affect the performance and service life of the machine tool. Generally speaking, the structure of the column of CNC machine tools can be divided into two types: single column and double column. The single column has a simple structure and low manufacturing cost, but relatively poor stability; the double column has a complex structure and high manufacturing cost, but good stability, which is suitable for high-precision and high-rigidity CNC machine tools. The material of the column of CNC machine tools is generally made of high-strength and high-rigidity alloy materials, such as HT300 cast iron, 40Cr alloy steel, etc. These materials have high bending resistance and Torsional strength can ensure that the column has good stability and precision during the processing. The processing technology of CNC machine tool columns mainly includes casting, machining, heat treatment, etc. Among them, the casting process requires the internal structure of the column to be uniform, without defects such as pores and sand holes; the machining process requires the surface accuracy of the column to be high and the shape error to be small; the heat treatment process requires the column to have sufficient hardness and toughness to improve the service life of the column. In short, the design and manufacture of CNC machine tool columns are important links in the manufacture of CNC machine tools, and the quality of their performance directly affects the processing accuracy and service life of CNC machine tools. In the prior art, during high-speed cutting or heavy-load processing, the column will vibrate or deform, affecting the processing accuracy. Therefore, it is necessary to design a CNC machine tool column. Utility Model Content
