硬质合金可转位刀具是刀具技术发展的一个重要方向。推广应用硬质合金可转位刀具的关键技术之一是刃磨硬质合金可转位刀片。一般都要求刀片的精度要高,互换性要好,尤其是可转位铣刀片和数控机床用可转位刀片。图1所示为正方形可转位铣刀片,有十八个面,它们的尺寸精度、形状精度、位置精度和 Cemented carbide indexable cutting tool is an important direction for the development of tool technology. One of the key technologies to promote the use of cemented carbide indexable cutting tools is the sharpening carbide indexable insert. Generally require the blade of high precision, interchangeability is better, especially indexable milling inserts and CNC machine tools with indexable inserts. Figure 1 shows a square indexable milling insert, with 18 faces, their dimensional accuracy, shape accuracy, position accuracy and
