提高铸件表面光洁度的问题,首先要抓路线,解决思想认识问题,紧密结合实际,具体地分析原因,不断解决具体技术问题。 1959年以后,我厂推广了潮模、潮芯铸造工艺。由于当时还没有完全掌握它的规律性,因此废品率较高,表面不光,成品车间职工和喷漆工人多次向铸造车间提出意见和要求。但有人说:“毛坯件还要那么光干啥?”“表面要是光还要磨刺,打泥子干什么?”“电机也不是艺术品,要那么好看有什么用。”“进口的电机表面上也不怎么样”。上述看法反映了我们很多同志对提高铸件表面光洁度,缺乏足够的认识。
Improve the casting surface finish, we must first pay attention to the line, to solve the problem of thinking, in close connection with the actual, specific analysis of the reasons and continue to solve specific technical problems. After 1959, our factory promoted the tide mold, the tide core casting craft. Because at that time, it had not completely mastered its regularity, so the reject rate was higher and the surface was not only that the finished workshop workers and the spray painters made many comments and requests to the foundry. But someone said: “The rough parts are so dry?” “If the surface is light but also grinding, mud do?” “The motor is not a work of art, so nice to see what’s the use.” “Imported motor surface Not very good on it. ” This view reflects the fact that many of our comrades lack sufficient understanding of how to improve the surface finish of castings.
