摘要： A disc-shaped tool 10 includes a plurality of virtual regions formed such that it is surrounded by two radius lines extending from a rotation center of a disc-shaped base metal 11 and two concentric circles on the base metal disposed around the rotation center. A central angle formed by the two radius lines is equal to or less than 90°, and the number of the virtual regions is 4 to 24. The concentric circle located in a center of an interval of the two concentric circles forming the virtual region is in a range of 0.6r to 0.8r with respect to the rotation center of the base metal when a maximum gullet bottom radius of the base metal is r. An overlapping of the virtual regions continuously adjoining each other is in a range of 0° to 12°. A minimum neighborhood distance between the adjoining slits is equal to or more than 0.05r. A ratio of a length of an arc of the central concentric circle in each virtual region with respect to the interval of the two concentric circles in the virtual region is 3 to 6.

摘要： A structure of circular saw in which the critical number of revolution is no t lowered even if the saw is made thin but can be doubled as compared with a conventional circular saw by solving the drawback of prior art that the critical number of revolution decreases as the circular saw is made thinner to cause buckling, and a method for fixing a circular saw to a main rotary spindle. Three slits are made in the body of a circular saw having a central hole to extend radially from the central hole or the vicinity thereof at a required angle, and the end of the slit is set within an annular range of 60 - 75% of the radius at the bottom of the circular saw. When such a circular sa w is fixed to a main rotary spindle, the circular saw is clamped from the opposite sides by means of a pair of flanges provided on the main rotary spindle such that movement of the body of circular saw is restricted in the thickness direction but radial enlargement/contraction incident to expansion/shrinkage of the body is allowed.

摘要： PROBLEM TO BE SOLVED: To solve the problem that in a hollow face type carbide tipped saw, a grinding length of a rake face is long, a grindstone can not be sent out to a tooth room side, grinding time is required, a biassed wear is generated in the grinding stone, a life of the grinding stone becomes short and cost is increased. SOLUTION: In the carbide tipped saw wherein the tip on which a recess is formed is fixed to a center in a tooth width W direction of a rake face in order to form a lateral rake angle of an angle θ equal to those of left and right side face cutting edges by seeing the tip of the tooth width W in a parallel direction of rake surface from a peripheral rake surface side, the rake surface has at least two rake surfaces of a first rake surface and a second rake surface. The saw contains the tip having the recess in both of the first rake surface and the second rake surface.

摘要： PROBLEM TO BE SOLVED: To make a circular saw usable in a high speed rotating region even if a base metal is thin by using the base metal which can be cut even in a rotating region being not less than the lowest critical number of rotations. SOLUTION: In a circular saw usable in a region being not less than the lowest critical no. of rotation when a work is cut and in two modes wherein the no. of knot circles of a base metal in the circular saw is 0 and the same number of knot diameters is n, when the inherent frequencies of the circular saw are fn1 (Hz) and fn2 (Hz) (wherein fn2>fn1), difference Δfn in the inherent frequency=fn2-fn1, the relative difference in inherent frequencies Δfn/fn1 is at least 3.0% at the knot diameter number n=3 and at least 3.5% at the knot diameter number n=4. As the thickness of the saw can be made thin as much as the base metal is made thin and cutting force per one tooth can be lowered by this, delivery speed can be set large and therefore, it is possible to improve work processing efficiency and efficiency.
