浇铸切削工具生产的发展,就是节省高速钢、金属切削机床、和人力;而这些对于加工用的成型材料和鍜件制成的工具是需要的。由于缺乏关于如何得到优质铸件的论述资料,因此阻挠了这种工具的产量的发展。本文根据工厂经验,研究了封闭浇铸系统(见译者注)的计算和选择。封闭浇铸系统是用于在乾砂型中浇铸切削工具。为了获得优质的切削工具铸件,要正确的计算内浇口切面和冒口重量。 [图一]至[图三]示浇铸三面铣刀和端面铣刀的切削部分所采用的封闭浇铸系统。为了获得封闭浇铸系统,便要使浇铸系统的每 The development of the production of casting cutting tools is to save high-speed steel, metal cutting machine tools, and manpower; these are required for the processing of molding materials and tools made of silicon. The lack of information on how to obtain high-quality castings has hindered the development of this tool’s output. Based on the experience of the factory, this article studies the calculation and selection of a closed casting system (see Translator’s Note). Closed casting systems are used to cast cutting tools in dry sand molds. In order to obtain high-quality cutting tool castings, it is necessary to correctly calculate the in-gate cut surface and riser weight. [Fig. 1] to [Fig. 3] show the closed casting system used for the cutting part of the cast face milling cutter and face milling cutter. In order to obtain a closed casting system, it is necessary to make each of the casting systems
