哈尔滨电机厂的yK16米立车是我国最大的立式车床,该机床为苏联40年代产品,最大加工直径达16米,加工重量180吨。我国重点建设工程葛洲坝上马后,必须用它来加工水电站用的水轮机。但此机床只完成部份加工任务,导轨即发生严重研伤事故,研伤面积达40～50%,局部深达0.5mm,机床精度完全丧失,润滑油每月流失损耗达数吨,油温超过警戒温度(50℃),起动电流达150A,超过额定最高电流达50%,机床无法证常运转,不得不停机维修。为了保证国家重点建设项目葛洲坝工
Harbin Electric Works yK16 meters vertical lathe is China’s largest vertical lathe, the Soviet Union for the 40’s products, the largest processing diameter of 16 meters, 180 tons of processing weight. Gezhouba key construction projects launched in China, we must use it to process hydropower turbine. However, the machine only completed part of the processing tasks, the rail that a serious accident, wound area of 40 to 50%, the local depth of 0.5mm, the complete loss of machine accuracy, loss of lubricating oil loss per month up to several tons of oil temperature More than the warning temperature (50 ℃), the starting current of 150A, exceeding the rated maximum current of 50%, the machine can not permit the normal operation, had to shut down maintenance. In order to ensure that the state’s key construction projects Gezhou dam workers
