Abstract
PURPOSE: To transfer chips to a space at a side of a saw blade used in finishing, by making a diameter of a bottom of a tooth of a circular blade at a side near a chipping blade, smaller than that at an opposite side, and smaller than a rotation diameter of a point of the chipping blade by a length of one chip. CONSTITUTION: A diameter of a sawdust gap of a circular blade 3 that is, a diameter of a bottom 6 of a tooth space 5, is determined to be smaller than the rotation diameter of a point 4 of a chipping blade 2. The difference between both diameters is determined to be at least equal to a length of a chip. Whereby the cut sawdust is discharged to the void cut by the chipping blade 2 without any restriction. In ordinary cases, it is not easy for the sawdust to move in a lateral direction from a tooth space 5, so that the bottom 6 of the tooth space is inclined at an angle α in the direction of the chipping blade 2, and this inclination makes the movement of the sawdust easy. This inclination is also effective in a view point of the abrasion of the circular blade 3. That is, the sawdust is discharged through the bottom 6 of the chip gap 5 without abrading a side part of the tooth, so that the life of the blade can be elongated.
