图示的万能滚压工具,可用于轴类表面或端面的精整加工,根据工件尺寸的大小,可随意选用适当直径的钢球。以小轴2将滚珠轴承3装在刀体1上,在座圈5上装有若干直径不同的钢球6,座圈可绕小轴回转。为保证各不同直径钢珠的底部,都能与滚珠轴承的外圈保持接触,座圈5的外圈与内圈要有一偏心 The illustrated Universal Rolling Tool can be used for finish machining of shaft surface or end surface. According to the size of workpiece, the ball with the proper diameter can be chosen at will. A small shaft 2 will ball bearing 3 mounted on the body 1, the seat ring 5 is equipped with a number of different diameter steel ball 6, the seat can be rotated around a small axis. In order to ensure the bottom of the different diameter steel ball, ball bearings can be kept in contact with the outer ring, the outer ring and the inner ring 5 have an eccentric
