【摘要】：不锈钢是不锈耐酸钢的简称,因其具有抗空气、抗蒸汽、抗水分以及抗酸等腐蚀的优良特性,被广泛用于航空航天、交通运输、石油化工以及核工业等领域。由于不锈钢中含有Cr、Ni、Ti和Mn等铁族元素,与硬质合金刀片中的Co元素属于同族元素,切削过程中容易产生刀-屑粘结和元素扩散等问题,是典型的难加工材料。首先对不锈钢的材质进行阐述;通过分析不锈钢切削加工特点,明确其难加工的本质原因;从刀具-工件匹配性、刀具结构-切削工况匹配性以及切削参数匹配性等方面进行研究,总结不锈钢高效切削刀具设计原则;最终,提出不锈钢车削专用刀具设计方法,研究数据以期为难加工材料的高效车削提供参考。
[Abstract]:Stainless steel is an acronym for stainless steel, which is widely used in aerospace, transportation, petrochemical and nuclear industry because of its excellent anti-air, anti-steam, anti-moisture and anti-acid corrosion characteristics. Due to the existence of iron group elements such as Cr-NiNI-Ti and mn in stainless steel, which belongs to the same group of elements as Co elements in cemented carbide inserts, it is easy to produce problems such as knife chip bonding and element diffusion in cutting process, so it is a typical refractory material. First of all, the material of stainless steel is expounded. By analyzing the characteristics of stainless steel cutting, the essential reason of its difficult to be machined is made clear. The design principle of stainless steel cutting tool with high efficiency is summarized in this paper. Finally, the design method of special tool for turning stainless steel is put forward, the tool structure and cutting condition matching and cutting parameter matching are studied, and the design principle of stainless steel cutting tool with high efficiency is summarized. The research data are expected to provide a reference for the efficient turning of difficult processing materials.
