对数控机床的用户来说,竞争的焦点是怎样能够快速地加工复杂工件,以降低机床成本。而数控机床及其部件的设计者和制造者,他们之间的竞争是怎样改进机床的性能,延长机床的使用寿命。新材料在机床部件上的应用机床在一定时间内的几何精度和尺寸精度与机床床身使用材料的稳定性有关。在传统的机床上,机床床身采用球墨铸铁或孕育铸铁,经热处理和精整加工制成。今天,随 For CNC machine users, the competitive focus is how to quickly process complex parts to reduce machine costs. The CNC machine tools and components designers and manufacturers, the competition between them is how to improve the performance of machine tools to extend the service life of the machine. The application of new materials in the machine tool parts The geometric accuracy and dimensional accuracy of the machine tool in a certain period of time are related to the stability of the material used by the machine bed. On traditional machine tools, the machine bed is made of ductile iron or cast iron, heat treated and finished. Today, with
