由于对发动机提高功率、降低油耗和废气排放的要求不断强化以及自动装配线的工艺要求,都对其零件的尺寸精度提出了更高的要求,为此,我们研制出一种新型曲轴磨床。利用这种曲轴磨床基本上达到了所要求的加工精度,并且在大量生产时,可使加工误差和工时都减少一半。该机采用了多砂轮 Due to the ever-increasing demands on the engine to increase power, reduce fuel consumption and exhaust emissions, as well as the technological requirements of the automatic assembly line, all of these places higher demands on the dimensional accuracy of their parts. Therefore, we have developed a new type of crankshaft grinder. This crankshaft grinder basically achieves the required machining accuracy and, in mass production, can reduce machining errors and man-hours by as much as half. The machine uses a multi-wheel
