Title:
鋸刃の歯形及びそのための方法
Document Type and Number:
Japanese Patent JP3720362
Kind Code:
B2
Abstract:
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.
