顶尖在机床上已得到广泛的应用 ,但由于被装夹工件的中心孔尺寸不易做得精确和保证较高的一致性 ,在车床或磨床上对工件的轴向尺寸链进行加工时 ,就需要进行多次重复对刀以确定刀具的参考原点 ;特别在使用数控机床进行大批量生产时 ,使用传统顶尖就很不适应 ,且浪费工时。新式
The top has been widely used on machine tools, but due to the fact that the center hole size of the workpieces to be mounted is not easy to do precisely and with a high degree of consistency, it is necessary to machine the axial dimension chain of a workpiece on a lathe or grinding machine Repeatedly repeated on the knife to determine the reference point of the tool; In particular, the use of CNC machine tools for mass production, the use of the traditional top is not suited, and a waste of man-hours.
