早在六十年代中期,联邦德国奥迪公司的曲轴专家们就认为,用传统的加工设备和方法来生产经久耐用、高性能的曲轴,其成本太高了。为此,该公司开发了一种可以加工新型曲轴的深滚机(图1)。
As early as the mid-1960s crankshaft experts at Audi AG in the Federal Republic of Germany believed that it was too costly to produce a durable, high-performance crankshaft using conventional machining equipment and methods. To this end, the company has developed a deep-crankshaft machine that can process new crankshafts (Figure 1).
