小型铸造阀体的材料大多采用铸铁或铜合金,切削性能比较良好,但是一次工序的加工时间很短,对加工中心说来就要频繁地调换工具。以前,日本国内多数是引进西德DIEDESHEIM公司的铸造阀体专用机,这种机器基本上符合了上述各种技术要求,但是主要的缺点是调换刀具困难,而且工位也只有3个至6个。日本三协精机制作所推出了一种新型的立式加工中心,它极适合于多品种小型铸造阀体的加工。文中列出了该加工中心的照片以及该机器的主要规格。利用一个典型的阀体铸件将西德专用机和日本的加工中心作了比较。原来的机器需用时100小时,而日本的加工中心只需46.8
Small cast valve body material mostly cast iron or copper alloy, cutting performance is relatively good, but a process of processing time is very short, it is necessary to change the tool frequently to the machining center. Previously, the majority of Japanese domestic companies were the casting valve special machines from West German DIEDESHEIM, which basically met the above technical requirements, but the main drawback was the difficulty in changing tools and the fact that there were only 3 to 6 work stations . Japan’s Samick Seiki introduced a new type of vertical machining center, which is very suitable for a variety of small cast valve body processing. The paper lists the machining center photos and the main specifications of the machine. A typical valve body cast was used to compare the West German machine with a Japanese machining center. The original machine took 100 hours, while Japan’s machining center only 46.8
