机床的发展大致有两个分支,其一是功能齐全的高精度通用机床,其二是功能高度单一的专用机床。日本丰和工业公司开发的高速DT中心即属后者,是钻孔与攻丝加工的专用机床。 1.开发初衷 丰和工业公司对已有的FTL的工艺种类进行的统计表明,在整个加工工艺过程中,钻孔与攻丝作业通常要占整个加工的2/3,其中,平均轴数为6轴,加工孔径在中10mm以内的孔约占96％。据此,该公司分析认为,如果开发一种高速、廉价的钻孔、攻丝作业专用加工中心,就可以使FTL中的多釉加工实现单轴化,从而可以避免繁琐的多主轴箱部件的设计,大幅度地降低FTL的制造成本。而且,由于单轴化机床结构单一,辅助件数
The development of the machine has roughly two branches, one is a fully functional high-precision general-purpose machine tools, the second is a highly functional single machine. The latter is the high-speed DT center developed by Japan’s Toyokawa Industrial Co., Ltd. It is a special machine tool for drilling and tapping. 1. Development of the original intention Feng and industrial companies on the existing FTL process types of statistics show that throughout the processing process, drilling and tapping operations usually account for the entire processing 2/3, of which the average number of axes 6-axis, processing aperture in the holes within 10mm about 96%. Accordingly, the company analyzed that the development of a high-speed, low-cost drilling and tapping operation dedicated to machining centers enables single-axis multi-glazing in FTL to avoid troublesome multi-spindle box components Design, significantly reduce the manufacturing cost of FTL. Moreover, due to the uniaxial machine tool structure, the number of auxiliary parts
