如图所未的圆弧刃铰刀,不仅工效高,并且铰孔质量稳定。这种铰刀的工作部分做成旋转椭圆体的形状,切削刃为圆弧刃,铰刀工作部分的长度L_1通常等于它的直径尺寸d(L_1=d),其轴线则与铰刀自身轴线一致。为了消除铰刀工作时和被铰孔之间的不同轴度,它不采用普通标准铰刀所常用的浮动装置,而是利用刀具工作部分是圆弧刃的特点促使刀具能相对于被加工孔定心,而中
As the unrecorded arc reamer, not only high work efficiency, and reaming quality and stability. The working part of the reamer is made in the shape of a rotating ellipsoid, the cutting edge is a circular arc edge, the working part of the reamer has a length L_1 generally equal to its diameter d (L_1 = d) Consistent. In order to eliminate the reamer work and reaming hole between the different axis, it does not use common standard reamers commonly used floating device, but the use of the working part of the tool is a circular arc edge features to promote the tool can be processed Hole centering, and in
