上海工具厂磨工钮荷生同志,创造性地运用了砂轮开槽磨削硬质合金的方法——间断磨削法,使硬质合金磨削做到了效率高、质量好、能防止裂纹,为硬质合金磨削开辟了一条简易有效的新途径。同时,这种方法不仅可以顺利地磨削各类硬质合金,也可以扩大推广到其他砂轮上磨削淬硬钢料,同样收到了良好的效果。由此看来间断磨削是磨削工艺上的一个飞跃。间断磨削法在国内曾经有过,但没有能显示出显著的效果,而被搁置了下来。钮荷生同志的这一发现,对当前我国机器制造业扩大硬质合金的使用有着重要的意义。过去,磨削质量问题一直是个关键,虽然采用金刚石砂轮,电加工等方法可以解决,但这不是所有工厂都能马上实现的。而间断磨削法具有简单易行,立竿见影的特点,这就为各地工厂扩大硬质合金使用,创造了非常有利的条件。间断磨削法发现以后,立刻受到了各级领导的重视和支持,通过了反复实践,反复认识,加之在推广过程中群众对它的不断丰富、不断发展,就目前看来,人们已在一定程度上掌握了这一事物的规律。间断磨削法看来似乎很简单,只不过是在原来的砂轮上开一些槽就行了,并没有甚么太多奥妙之处。其实要真正掌握它的规律也并非容易。间断磨削法过去没有能够收到应有效果,恐怕关键也就在这里。因此我们在学习推广这一先进经验时,不要认为它简单好学,一知半解就自我满足。在这个问题上,我们应该按照毛主席的教导:“学习的敌人是自我满足,要认真学习一点东西,必须从不自满开始”。我们相信,随着这一经验为广大群众所掌握,人们将会在广泛的实践中,进一步地丰富它、发展它,使我们能够更加全面地、深刻地掌握它的规律性。当然好经验中也会有缺点,问题在于我们只有全面地认识它,才能更好地使用它。 Shanghai Tool Factory mill workers Hok Ho students, creative use of grinding wheel slotted carbide grinding method - discontinuous grinding method, the carbide grinding to achieve high efficiency, good quality, to prevent cracks, hard Alloy grinding has opened up a simple and effective new way. At the same time, this method not only can successfully grind various types of cemented carbide, but also can be extended to other grinding wheels for grinding hardened steel, and also received good results. It seems that the intermittent grinding is a leap in the grinding process. Discontinuous grinding method has been in the country, but failed to show significant results, and was shelved. This discovery by Gunjong Hojo is of great significance to the current expansion of the use of cemented carbides in the machinery manufacturing industry in our country. In the past, the problem of grinding quality has always been a key issue. Although diamond grinding wheels and electrical processing can be used, this is not something that all factories can achieve right away. The intermittent grinding method has the characteristics of simple and immediate, immediate, which for all parts of the factory to expand the use of cemented carbide, and created very favorable conditions. After the discontinuous grinding method was discovered, it was immediately valued and supported by the leaders at all levels. It passed repeated practice and repeated understanding. In addition, the masses continued to enrich and develop it during the promotion process. At present, people have been certain To a degree mastered the law of this thing. Intermittent grinding seems very simple, but only to open some slots on the original grinding wheel on the line, and there is nothing too much mystery. In fact, it is not easy to really grasp its laws. Discontinuous grinding method in the past did not receive due effect, I am afraid the key is here. So when we learn to promote this advanced experience, do not think it is simple and studious, little understood on self-satisfaction. On this issue, we should follow Chairman Mao’s teachings: “The enemies of learning are self-satisfied, we must conscientiously study something and must never begin with complacency.” We believe that as this experience is mastered by the broad masses of the people, people will enrich and develop it further in a wide range of practices so that we can grasp its regularity more comprehensively and profoundly. Of course, there will be disadvantages in good experience. The problem is that we can make better use of it only if we fully understand it.
