国产刀具和国外刀具相比,切削寿命有较大的差距,有人怀疑刀具材料不给力,不如国外好,于是从国外进口M42、M35等高性能高速钢甚至粉末高速钢,但刀具质量还是不如人家。行家们分析认为是热处理技不如人。以下就如何提高刀具寿命谈点切身体会,仅供参考。1.重视碳化物的核心作用高速钢热处理搞来搞去都在做碳化物的转变与转化工作。碳化物对高速钢刀具来说,是一把双刃剑,处理得好,它能保证高速钢有很高的硬
Compared with foreign tools, domestic knives have a big gap in cutting life. Some people doubt that the knives will not give force and are better than foreign ones. Therefore, M42, M35 and other high-speed high-speed steel or powder high-speed steel are imported from abroad, but the quality of knives is still not as good as that of others . Experts believe that heat treatment is not as good as people. The following on how to improve the life of the tool to talk about personal experience, for reference purposes only. 1. Attach importance to the core role of carbide High-speed steel heat treatment engage in the transformation and transformation are doing carbide work. Carbide is a double-edged sword for high-speed tool steel that is well-handled to ensure high-speed steel has a very high hardness
