随着切削条件的变化,尤其是切削速度的不断提高,10年来,刀具材料有了巨大的发展。表1为刀具材料发展的简明年表,本文主要说明表中粗线以下部分的发展情况。图1是按耐磨性和韧性这两个基本特性来衡量各种刀具材料的相应位置。图中表明,任何一种刀具材料,较之研制初期,耐磨性和韧性都有不同程度的提高,空白部分为初期性能,斜线部分为提高后的性能;近10年来性能提高最显著,且大量投放市场的材料为涂层硬质合
With the change of cutting conditions, especially the continuous improvement of cutting speed, the cutting tool material has undergone tremendous development over the past 10 years. Table 1 is a concise chronology of tool material development, this article mainly describes the development of the following part of the thick line in the table. Figure 1 is based on two basic characteristics of wear resistance and toughness to measure the corresponding position of various tool materials. The figure shows that any tool material, compared with the initial development, wear resistance and toughness have varying degrees of improvement, the blank part of the initial performance, the slash part is to improve the performance of the past 10 years the most significant increase in performance, And a large number of materials on the market for the hard coating cohesion
