    摘要： A saw blade has a plurality of teeth with each tooth formed by a beveled leading face, a beveled trailing face and a chamfered surface located on the trailing face of each tooth. The trailing and leading faces are beveled in opposite directions in alternate order throughout the saw blade prior to the forming of the chamfered surface. The beveled leading face of each tooth intersects the chamfered surface on the trailing face of each tooth to form a curved cutting edge having a negative rake angle. The beveled faces are manufactured by first forming a plurality of rough-formed gullets. The rough-formed gullets are then finished-formed into beveled gullets by a cold-forming operation prior to the grinding of the chamfered surface to form the curved cutting face of the tooth.

    摘要翻译： 锯片具有多个齿，每个齿由倾斜的前表面，斜面的后表面和位于每个齿的后表面上的倒角表面形成。 在形成倒角表面之前，后缘和前导面在整个锯片上以相反方向以相反的方向倾斜。 每个齿的倾斜的前导面与每个齿的后表面上的倒角表面相交，以形成具有负前角的弯曲切削刃。 通过首先形成多个粗糙的齿槽来制造斜面。 然后，在研磨倒角表面之前，通过冷成型操作将粗糙的齿槽精加工成倾斜的齿槽，以形成牙齿的弯曲切割面。
