要提高劳动生产率首先必须靠繁重的手工劳动的机械化。这种要求使技师们想到必须用磨削来代替极其繁重的蒸汽透平机汽缸接合面以及其他类似件的刮的工序。 必须设计出磨削长达4公尺宽达2～2.5公尺的零件的工艺方法及施工设备。利用同一的刀架又作刨加工又作磨削加工。工作物3刨 To raise labor productivity must first rely on heavy manual labor mechanization. This requirement makes technicians think of the need to use grinding instead of extremely heavy steam turbine cylinder joints and other similar scraping processes. Must design the process method and the construction equipment which grinds the part which is up to 4 meters in width to 2 ~ 2.5 meters. Use the same tool holder for sharpening and grinding.
