铸造高速钢刀具的应用,在很大程度上取决于材料的机械性能;即能否经受切削过程中的各种负荷。因此在铸造高速钢刀具的研究和实践中,对铸造高速钢机械性能的试验以及铸造试样的合理选取,是很重要的工作之一。对普通的碳钢铸件和合金钢铸件,在国外已有广泛的研究,试样有浇入湿砂型的,也有浇入干砂型的,例如在苏联就有国家标准明确规定。对于熔模精密铸造钢铸件的拉伸试样和冲击试样,近来很多国家也都进行了研究。但是国内对这方面的工作还不多,一般生产工厂对试样的选取,大多是浇成圆柱形试样或从
The application of cast HSS tools depends to a large extent on the mechanical properties of the material; that is, whether or not it withstands the various loads involved in the cutting process. Therefore, casting high-speed steel cutting tool in the study and practice, the casting of high-speed steel mechanical properties of the test and the casting sample is a reasonable choice, is one of the important work. Common carbon steel castings and alloy steel castings have been extensively studied in foreign countries. Specimens have been poured into wet sand molds and poured into dry sand molds. For example, in the Soviet Union there are clearly specified national standards. Tensile specimens and impact specimens for precision cast steel casting have recently been studied in many countries as well. However, the domestic work on this area is not much, the general production plant on the sample selection, mostly poured into a cylindrical sample or from
