橡胶压延机的主要零件轧辊,其工作表面相对于热装其上的轴承内圈的外圆,圆跳动量要求小于0.005mm(见图)。为了达到这项精度,特殊订购的轴承内圈不是成品,而是外圆留有一定余量的半成品。经过加热到150℃以后,套装在轧辊轴颈上,然后同次磨削轧辊工作面和轴承内圈的外圆。由于被磨削的工 Rubber calender main part of the roll, its working surface with respect to the thermal load on the bearing inner ring of the outer circle, circular runout requirements of less than 0.005mm (see photo). In order to achieve this accuracy, the special order of the inner ring is not a finished product, but leave some margin of semi-finished products. After heating to 150 ℃, the package in the roll journal, and then the same time grinding the roller face and bearing the inner circle. Due to the grinded workers
