洛阳东方红拖拉机厂继1975年大量采用液体静压技术改装各类旧磨床成功以来,最近又成功地改造了两台3160A曲轴磨床,并用于流水生产线上,获得了显著的效果。原两台3160A曲轴磨床用于75发动机曲轴的半精磨和精磨两道工序上,加工工时共需13分多钟,现用一台采用静压轴承改造磨头的机床,两道工序合并磨削仅4分钟完成,功效成倍增加,并提高了精度,光洁度比前提高一级多,达(?)9～(?)10。
Luoyang Dongfanghong Tractor Factory Following the success of the extensive use of hydrostatic technology in 1975 for various types of old grinding machines, the company recently successfully rebuilt two 3160A crankshaft grinders and used them in streamline production lines to achieve significant results. The original two crankshaft grinding machine 3160A crankshaft for 75 crankshaft semi-precision grinding and refining two processes, processing time is a total of more than 13 minutes, now using a static pressure bearing renovation grinding head machine, the two processes combined Grinding only 4 minutes to complete, the effect multiplied, and improve the accuracy, finish more than one level, up (?) 9 ~ (?) 10.
