本文对电炉常用的几种特殊金属材料的机械性能和物理性能以及它们在切削加工过程中出现的各种现象进行了分析。 根据这些材料的加工复杂性能,介绍了切削加工的刀具材料和刀具几何角度的选择。电炉行业在现有的机床设备条件下,如果采用这些刀具材料和几何角度,不但能解决切削加工难的问题,而且能使每只零件达到原设计的精度要求。 In this paper, the mechanical properties and physical properties of several special metal materials commonly used in electric furnace and their various phenomena in the cutting process are analyzed. According to the complex machining performance of these materials, the cutting tool materials and tool geometries are introduced. Electric furnace industry in the existing machine tool conditions, if the use of these cutting tool materials and geometric perspective, not only to solve the problem of cutting difficult, but also to make each part meet the original design accuracy requirements.
