The main topic on porous drilling spindle box of modular machine tool for design. In this design, the data calculation based on standard parts to do a careful selection, and on the basis of the feature of processed parts, machining parts size precision, surface roughness, and a positioning clamping means, process and processing in the course of cutting tool, productivity, and design reasonable structure of box.Key words: modular machine tool, spindle, process flow 朗读 显示对应的拉丁字符的拼音 组合机床是以通用部件为基础，配以按工件特定形状和加工工艺设计的专用部件和夹具，组成的半自动或自动专用机床。组
