一九七七年十二月七日至十二日,湖北省少无切削加工经验交流会在麻城召开。这次会议的内容有精密铸造、粉末锻造、精锻、冷镦冷挤、温挤和工程塑料压制等。会上有14个单位介绍了经验。锻压方面有:温挤异形零件3Cr13不锈钢阀瓣(武汉锅炉厂、华中工学院),提高工效20～30倍;伞齿轮和元柱直齿轮粉锻(湖北农机学院、武钢)。此外,还有非标准螺钉类零件的冷镦冷挤等。会议还举办了实物展览。会议最后讨论落实了湖北省一九七八年推
From December 7 to December 27, 1977, the exchange of experience in machining without cutting in Hubei Province was held in Macheng. The contents of this meeting are precision casting, powder forging, precision forging, cold heading cold extrusion, temperature extrusion and engineering plastics and so on. There are 14 units at the meeting introduced the experience. Forging aspects: temperature extrusion shaped parts 3Cr13 stainless steel valve (Wuhan Boiler Factory, Huazhong Institute of Technology), to improve work efficiency 20 to 30 times; bevel gear and column spur gear forging (Hubei Agricultural College, Wuhan Iron and Steel). In addition, there are non-standard screws cold heading cold extrusion and so on. The meeting also held a physical exhibition. The final discussion of the meeting was implemented in 1978 in Hubei Province
