摘要： PROBLEM TO BE SOLVED: To make generation of a knife mark not conspicuous on a worked surface while generation of burrs are decreased without lowering working efficiency of a milling cutter and a tool life in a chamfering working method for forming a slant at a corner part of a material to be cut by using the milling cutter for woodworking. SOLUTION: A blade part 12 provided to a body periphery of the milling machine for woodworking 10 has a side cutting edge 13 wherein a cutting angle in a direction of expanding on an axis M side is within a range of θ=2 deg.-30 deg., and a rotary surface of the milling cutter cuts the slant at a position wherein a rotary surface of the milling cutter is inclined at an angle θ to a slant angle αof the slant 22 of the corner part of a material to be cut 20. Further, an inner peripheral edge of the side cutting edge is positioned in a state being not concerned in cutting, the outer peripheral edge of the side cutting edge is positioned to a side separating from the material to be cut to a surface which passes an apex at the corner before cutting the material to be cut and is parallel to a rotary surface of the milling cutter, and cutting is carried out.

摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing for a cutting edge tip that has a recessed and a projected part serving as datums for a cutting-edge point position and serving to prevent dislodgment and a fling when the cutting edge tip is secured as an inserted tip in a milling cutter for a wood working machine, and that is usable, without additional machining, in a state where it is cut from a rectangular parallelepiped of secondary raw material. SOLUTION: A rectangular parallelepiped 6 with at least one high-hardness layer 1 is cut continuously by discharge wire cut in a slant direction across the high-hardness layer 1 into a plurality of cutting edge tips 7. In the cutting, the high-hardness layer 1 and the cut face form a cutting edge 7f, and the cutting edge tip 7 is provided on its front and rear faces 7b and 7c with a recessed line and a projected line paired in aligned positions so as to extend in such directions as to prevent dislodgment.

摘要： PROBLEM TO BE SOLVED: To improve a cutting accuracy, to extend a life of a circular saw, and to economically control an occurrence of noise by removing a chattering vibration of a circular saw during cutting operation. SOLUTION: An arrested engagement gear train is constituted by disposing three or more odd numbers of intermediate gears which rotate synchronously and in circular engagement with a main shaft gear 29 fixed to a main shaft 26 of a circular saw cutting machine. A rotating power of an electric motor is transmitted to one of the intermediate gears 33, at least one of the intermediate gears 33 is movable, and load is imposed on at least one of the movable intermediate gears 33, thus removing a backlash of the arrested engagement gear train. The sum J (kgf.m.sec2) of a moment of inertia converted to a main spindle including the main spindle of each spindle which interlocks in a condition such that the backlash is removed from the main spindle satisfies an equation J>=F×(D/2)[1000×250×(N/60)2], where D (mm) is a diameter of a circular saw, N (rpm) is a number of rotation, and F (kgf) is a cutting force per blade as a compornent of force.

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.

摘要： PROBLEM TO BE SOLVED: To make the tip parts of a central cone and others which are fitted to the end of a rotary cutting tool having a cutting blade of high hardness sintered body resistant to breakage. SOLUTION: A boring cone D1 for wood working is cut out from an intermediate product in which an end part material formed by sintering a rigid backing layer L1, a high hardness sintered body layer L2, and a rigid backing layer L3 integrally is joined to a shank material by brazing. Namely, a central cone 10 is formed from a cemented carbide, round bristle draw blades 7, 8 and a bottom blade 9 are formed from a high hardness sintered body containing diamond particles and cubic boron nitride particles, and a supporting base material is formed from a cemented carbide.
