摘要： A cutting tool is rotatable about an axis line, and includes a main body portion, a cutting insert, and a plurality of anti-vibration members. The main body portion has an inner circumferential surface and an outer circumferential surface opposite to the inner circumferential surface. The cutting insert is attached to at least one of the inner circumferential surface and the outer circumferential surface. Each of the plurality of anti-vibration members is provided at the main body portion. Each of the plurality of anti-vibration members includes a weight member composed of a material having a specific gravity larger than a specific gravity of a material of the main body portion.

摘要： A tool holder is provided which enables the coupling of a tool holder body (11), regardless of the size of its outside diameter, to a tapered shank (10), which is hardly influenced by centrifugal force generated at the time of high-speed rotation, and which can cause elastic deformation of the tapered shank (10) effectively. The tool holder comprises the tapered hollow shank mounted on a machine tool spindle (100) and the tool holder body (11) coupled to the tapered shank (10). The tapered shank (10) and the tool holder body (11) are coupled to each other in the state where a part of the tapered shank is inserted in the tool holder body.

摘要： A throw-away tip (1) has cutting edge (5) being so tilted as to place a height from a position of the bottom surface (3) of the tip higher on the side of a cutting edge portion than that on the side of a base portion for forming a tilted surface (2a) descending from the cutting edge portion to a center portion. Flank surfaces (6) on side surfaces along the cutting edge portion is convex arc-shaped surface bulging outwardly from a perpendicular line extended from a peak of the cutting edge to the bottom surface position of the tip on the side of the cutting edge portion of the cutting edge, at least on the side of the cutting edge portion, and continuously and gradually inclined toward inside of the tip from the perpendicular line from the side of the cutting edge portion to the side of the base portion. In the position installed on a throw-away type cutter (10), the throw-away tip forms large positive angles of axial rake angle and radial rake angle to certainly provide high cutting ability, high strength of the cutting edge and high fixing strength onto a cutter body. The tip permits increasing of rigidity of the cutter body by mounting at high axis position. Also, the tip facilitates production.

摘要： A tapper mechanism has a tapper body (30) driven to rotate and having an incorporated clutch (31), the mechanism further having a driven shaft (32) rotatably held in the tapper body. An engageable claw (33) connected to and carried by the driven shaft (32) releasably engages with the clutch (31) so as to transmit a torque from the tapper body (30) to the driven shaft (32). The driven shaft (32) is movable in an axial direction of the tapper body (30) a predetermined stroke such that the claw (33) is disengaged from the clutch (31), to thereby intercept the torque and switch the driven shaft (32) into a neutral state. The tapper mechanism further has a slipping means such that the claw can quickly disengage from the clutch when it is shifted into the neutral state.

摘要： A cutting insert has a seating surface, an outer peripheral surface, a top surface, and an attachment hole. The cutting edge includes a curved cutting corner edge portion, a first cutting edge portion contiguous to one end of the cutting corner edge portion and extending linearly, and a second cutting edge portion contiguous to the other end of the cutting corner edge portion and extending linearly. The top surface includes a first rake face contiguous to the first cutting edge portion, a second rake face contiguous to the second cutting edge portion, and a third rake face contiguous to the cutting corner edge portion and also contiguous to the first and second rake faces. The third rake face has a first region contiguous to the first rake face and a second region contiguous to the second rake face. The first rake face and the first region each have a rake angle which is a positive angle. The second rake face and the second region each have a rake angle which is a negative angle.
