消音防振铰刀，如图1所示。硬质合金（YG3）刀头1焊接在刀齿体2上，刀齿体的背面铣有数条纵向肯槽，压入铰刀体的齿槽中，齿槽配合面轴向倾斜3”，既方便刀齿体的装卸，又在自锁角的范围内，故可保证铰刀工作中的轴向、径向定位要求。每对铰刀齿都呈中心对称分布，以便修磨时能 Silencer anti-vibration reamer, shown in Figure 1. Carbide (YG3) cutter head 1 is welded to the cutter body 2, a plurality of longitudinal flutes are milling on the back face of the cutter body, and are pressed into the alveolus of the reamer body with an axial slant of 3 " Convenient knife body loading and unloading, but also in the range of self-locking angle, it can ensure reamer work in the axial and radial positioning requirements. Each pair of reamer teeth were symmetrical center distribution, so that when grinding
