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： The present invention provides a cutting tool insert capable of realizing a sufficiently large axial rake angle, exhibiting improved cutting ability, and conducting stable processing with little cutting vibrations, and also provides a cutting tool onwhich this insert is mounted. Specifically, an insert 1 and a cutting tool 100 on which the insert 1 is mounted are provided. The insert 1 is in a substantially plate form and of polygonal shape and is provided with a major cutting edge 16A (or 16B) extending from one corner 14A (or 14B) toward the other corner 15A (or 15B) as viewed from above. The major cutting edge 16A (or 16B) comprises a first edge line and a second edge line that meet to form an obtuse angle, which causes the area where the first and second edge lines meet to protrude slightly outwards, as viewed from above. The first edge line slopes down towards the second edge line so as to make the distance with a seat face 11 decrease gradually as viewed from the side, and the first edge line forms an obtuse angle with the second edge line causing the top face area to dip down towards the seat face, and, further, the first edge line is shorter than the second edge line.
