通过对威克萨斯克冶金工厂（BMg）生产的铁路整体辗钢轮的研究，发现了许多感兴趣的特点。在与生产水平开始下降的最近几年多少有些不同的1988年，在轮钢机械加工（还未完成形面加工、各种切割工序）时的废品为6426件。在其他车轮辗压车间也有类似的情况。这种废品是由于刀具磨 A number of interesting features were discovered through a study of the railway rolling wheels produced at the BMX plant. In 1988, somewhat different from the recent years when the level of production began to decline, there were 6,426 wastes used in the machining of wheel steel (not yet finished surface processing, various cutting processes). In other wheel rolling workshop there is a similar situation. This waste is due to the tool grinding
