在金属切削加工领域里。目前不重磨式刀具占主流。CBN、陶瓷等刀具材料的不断研制和性能的提高,都取得了显著的成就.但如图1所示,切削加工中,切屑排除量的大部分都是碳钢、合金钢、铸铁等主要材料在一般切削过程中产生的.硬质合金和涂复材料是当前主要的刀具材料(1978年日本的不重磨刀片中,这两种材料占20%以上),这种状况,在今后短期内也不会有大的变化,因为金属切削加工生产率的提高,并不单纯取决于刀具材料的性能,而是和被加工材料,机床系统(转速、功率、刚性、精度)、工具系统(材质、形状、刀杆等)以及其他各种因素的综合性能密切相关的.
In the field of metal cutting. At present, heavy-duty tool is the mainstream. CBN, ceramic and other cutting tools continue to develop and improve performance, have made remarkable achievements.But as shown in Figure 1, cutting, the majority of chip exclusion are carbon steel, alloy steel, cast iron and other major materials Carbide and coating materials are the main tool materials currently used (more than 20% of the non-refurbished blades in Japan in 1978). This situation is expected to be achieved in the near future There is no big change because the improvement of metal cutting productivity does not depend solely on the performance of the tool material but on the material to be machined (machine speed, power, rigidity, accuracy), tooling system (material, Shape, arbor, etc.) and other various factors are closely related to the overall performance.
