国营虬江机器厂工程师曹存昌学习苏联火焰淬火法成功,解决了制造精密镗床的关键问题。虬江机器厂自1951年开始制造镗床以来,镗床的主轴“镗杆”老是容易弯曲和断裂,去年制造73根镗杆中,就报废了54根。这不但给国家造成了巨大损失,而且常常是镗床的其他零件都已装配好了,独缺一根镗杆,影响了全厂生产住务的完成。 Cao Cunchang, an engineer at the state-owned Qijiang Machinery Factory, learned about the success of the flame-quenching process in the Soviet Union and solved the key problems in the manufacture of precision boring mills. Since Jiangling Machine Works started making boring machines in 1951, the “boring bar” of the boring machine has always been easy to bend and break. Last year, among the 73 boring bars manufactured, 54 were scrapped. This not only caused huge losses to the country, but also other components of the boring machine were often assembled. The lack of a boring bar completely affected the completion of production of the whole factory.
