    摘要： A radial saw blade is formed of a flat disc having peripheral edge including circular peripheral portions and recessed stepped peripheral portions. The peripheral edge includes spaced apart, radially inwardly extending notches. Each notch has a flat, plate-like insert brazed to an L-shaped seat in the notch facing the direction of rotation. Each insert has cutting edges formed on side edges of the inserts which extend axially from both sides of the disc and on a crown edge extending radially from the peripheral edge of the disc. The side and crown edges each have beveled surfaces extending away from the direction of rotation to define a relief angle. A first set of the notches are positioned about the circular peripheral portion of the peripheral edge. The inserts in the first set of notches make the primary cut in both linear and non-linear passes. A second set of notches are circumferentially spaced along the recessed peripheral portions, or stepped portions, of the blade and are located at different radial distances from the center of the disc. The side cutting edges of the inserts in the second set of notches radially overlap the side cutting edges of radially adjacent cutting inserts in the second set of notches. The inserts in the second set of notches plane the raw cut edges cut by the first set of inserts on straight cuts. The inserts in the second set of notches also cut in the axial direction relative to the disc for curved and diagonal cutting to prevent the blade from binding in the kerf by providing axial relief.

    摘要翻译： 径向锯片由具有圆周边缘和凹陷阶梯状周边部分的周缘的扁平盘形成。 周缘包括间隔开的径向向内延伸的凹口。 每个凹口具有平坦的板状插入件，其在面向旋转方向的凹口中钎焊到L形座。 每个插入件具有形成在插入件的侧边缘上的切割刃，其从盘的两侧轴向延伸并且在从盘的周边边缘径向延伸的冠缘上形成。 侧面和冠部边缘各自具有远离旋转方向延伸的倾斜表面，以限定一个仰角。 第一组凹口围绕周边边缘的圆形周边部分定位。 第一组凹口中的插入件在线性和非线性通道中进行初级切割。 第二组凹口沿着刀片的凹陷的周边部分或阶梯部分周向间隔开并且位于与盘的中心不同的径向距离处。 第二组凹口中的插入件的侧切割刃径向地与第二组凹口中径向相邻的切削刀片的侧切削刃重叠。 第二组凹口中的插入物将由直线切口上的第一组插入物切割的原始切割刃平面。 第二组凹口中的插入件也相对于盘沿轴向切割以进行弯曲和对角切割，以防止刀片通过提供轴向浮雕而在切口中结合。
