T62 1 6落地镗是 1 977年上海第二机床厂生产的 ,首批采用了可控硅整流技术实现主轴和进给的无级调速。但其电气线路设计、元器件质量都有缺陷 ,严重影响到该机的使用性能。为此 ,我们用武汉重型机床厂生产的控制电柜 KTB- 5 0 A对其电气进行改造。在施工调试和以后的运行中 ,
T62 1 6 floor boring is the second machine tool factory in Shanghai in 1977, produced the first batch of SCR rectifier technology to achieve spindle and feed stepless speed regulation. However, its electrical circuit design, component quality are flawed, seriously affecting the performance of the aircraft. To this end, we use the Wuhan Heavy Machine Tool Plant production control cabinet KTB-5 0 A to its electrical transformation. In the construction and commissioning of the operation,
