高速钢杆形工具淬火后的校直原理通常认为,是利用钢的塑性和组织内存在塑性好的奥氏体。我们在拉刀校直的探索中,感到以上的说法没有触到实质,而只是问题的次要因素。现将我们的看法和生产经验介绍如下。 High-speed steel rod-shaped tools after quenching the principle of straightening is generally believed that the use of steel and plasticity in the organization of plastic good austenite. In the exploration of broaching and straightening, we felt that the above statement did not touch upon the substance but only a secondary factor in the problem. Now we view and production experience are as follows.
