摘要： PROBLEM TO BE SOLVED: To provide a rotatable tool for chip removing machining including two parts of a holder part 1 rotatable around a geometric center axial line C, and a replaceable cutting part 2, in which the cutting part can tightly be connected to the holder part by male-female couplings of a taper seat 5 in the holder part and a taper male member 14 protruded from the cutting part. SOLUTION: A seat slot 6 separates protruded parts 7 and 8 which elastically offset and the protruded part is tilted inward when the male member 14 is fastened to the seat 5. The male member comprises a sheath-shaped body 14 and a guide groove seat 5 opened along radial direction side surface. Since the sheath-shaped body is laterally moved outward or inward the guide groove, at least one outside wedge surface of the sheath-shaped body 14 tilted to the center axial line C is disposed to get in contact with an inner wedge surface 25 to regulate the guide groove. The sheath-shaped body and the guide groove include means 26 and 27 to position the sheath-shaped body.

摘要： PROBLEM TO BE SOLVED: To provide a coated cutting tool for chip forming containing at least one layer of an alumina (Al2O3) which is formed by a film featured by fine equi-axed grain. SOLUTION: At least one layer substantially consists of α-Al2O3 and a body at least partially coated by a plurality of heat resistant layers is provided. The layer of Al2O3 is formed of substantially equi-axed grain having an average grain size of 1 μm or less and has bimodal grain size distribution consisting of coarse grains having an average grain size of 0.5-1 μm and fine grains having an average grain size of up to 0.5 μm. Further, a layer of Al2O3 contains a groove-form region containing titanium (at least 5 at.%) but containing neither nitrogen nor carbon. The special microscopic texture is achieved by temporarily stopping gas necessary to growth of a layer of Al2O3 and introducing TiCl4.

摘要： PROBLEM TO BE SOLVED: To provide an assembled cutter body, a method of assembling cutting inserts onto the cutter body, and the cutting inserts themselves. SOLUTION: Respective cutting inserts 26 are built in the outer periphery of a tool holder 22 by respective fastening screws 28. Each insert 26 is mounted on a support surface, and each fastening screw 28 is passed through the center hole 29 in the insert 26, and screwed into a mounting hole 30 formed in the support surface. This mounting hole 30 is disposed in the non-vertical direction of the support surface, a fastening screw 28 forms a certain angle with the axial line of a through-hole 29 in the insert 26 to allow a screwdriver to more easily reach the fastening screw. The through-hole has a conical or spherical part for supporting a spherical head of the fastening screw 28.

摘要： PROBLEM TO BE SOLVED: To provide a drilling tool that includes a shaft releasably connectable to a cutting body with a cutting edge at the front end. SOLUTION: The drilling tool including a shaft 1 has, at the front end of the shaft 1, a seat bounded by interspaced projections 4 and 5, between which a bottom is present. The projection 4 has a tapped hole for a screw 8. The screw alone guarantees the fixation of a cutting body, and has a characteristic of prestressing the cutting body when tightened. The opposite projection 5 internally has a support shoulder 15, against which the cutting body is pressed when the screw is tightened to prestress the cutting body laterally. The projections 4 and 5 are displaced laterally from each other to expose the screw beside the projection 5 without obstruction.

摘要： PROBLEM TO BE SOLVED: To form a wedge unit surely automatically lockable in the case of clamping a tool, by providing one or a plurality of transverse grooves in a cone surface of a piston protrusion, and discharging hydraulic pressure oil from an interface between the cone surface and an inner surface side of a plurality of the wedge units in cooperation with the cone surface. SOLUTION: A piston device 14 for a tool holder consists of a piston main unit 16 and a piston protrusion 17 protruded to the forward. The protrusion 17, having first/second cone surfaces 33, 34, has a thin constrictive part 35 between the second cone surface 34 and the piston 16. Each of a plurality of wedge units 31 with a space apart in a tangential direction has an arch type surface 36 of recessed shape in an inner side intending contact with the first cone surface 33. A plurality of grooves 40 are formed in the cone surface 33. Each groove 40 is provided on a surface annular and vertical to a center axis of the protrusion 17. In the case that the piston device 14 is retracted, oil in an interface between the surfaces 33, 36 is discharged, contact is generated by rapidly increasing friction between both the surfaces, and the wedge unit 31 can be automatically locked with certainty.

摘要： PROBLEM TO BE SOLVED: To improve the toughness of the alloy while its sufficient deformation resistance and wear resistance are maintained by forming a binder of Co of a specified amt. contg. only Ni and Fe on impurity standards. SOLUTION: In the case of being circulated to ordinary finish turning and profile or finish milling or the like for steel including light discontinuous cutting, the content of Co in a binder is controlled to 9 to 12 mass %, preferably to 9 to 10.5 mass %. There is a need of sufficiently increasing the solid solution in the binder, and for this purpose, a hard layer is embodied by a method of dissolving W atoms into Co. In this alloy system, the binder is essentially composed of a Co-W solid solution. Ordinarily, the solid solution strengthening is directly measured as relative magnetic saturation. By reducing the content of carbon in the alloy, the solid solution strengthening increases, but it reaches the maximum at the relative magnetic saturation of about 0.75 and is no longer increased. The relative magnetic saturation shall most preferably be held to
