Diamond cutting saw blades |
摘要 |
In a diamond cutting saw blade, a plurality of slits 1 are formed at regular intervals on the outer periphery of a disc-shaped iron substrate 2, and a plurality of segment chips 3 are fixed onto the outer periphery of the disc-shaped iron substrate 2. Two trapezoidal concave portions 4 which expand outwardly are formed on both sides of the outer periphery of each segment chip 3. Further, a trapezoidal concave portion 5 is formed at the intermediate position of the segment chip 3 on a joint surface of the iron plate 2 so as to expand toward the joint surface. At the corner where a bottom surface 4a and a tapered surface (side surface) 4b of the concave portion 4 formed on the outer periphery intersect, there is formed a curved surface 4c having a radius of 1.0 to 2.5 mm. Similarly, in a concave portion 5 formed in the inner periphery of the segment chip 3, there is formed a curved surface 5 c having a radius of 1.0 to 2.5 mm at the corner where a bottom surface 5a and a tapered surface (side surface) 5b intersect each other.
