In hydropower products, the extra large ring parts of the bulb tubular turbine and the axial flow turbine need to be processed on the numerical control equipment, and the processing range is large, the profile is complicated, the cutting amount is large, the processing is difficult, and the problems are many. Especially in the case of insufficient processing capability of CNC vertical lathe, the traditional model processing method is particularly important and effective. There are many such examples, and only one of them is used to illustrate the problem. The processing of the runner room of Hunan Lingjintan Power Plant is due to the high height of the workpiece (4270mm), which cannot be used on the 12.5m CNC vertical car.
