    摘要： In a rotary cutting tool for use with at least one cutting tip, a cutter body has its forward end whose outer periphery has mounted thereto the cutting tip. A chip suction device is arranged outwardly of an outer peripheral surface of the cutter body for drawing chips generated by the cutting tip. The chip suction device includes a generally cylindrical cover unit having a wall for covering the cutter body. The cover unit is supported by the cutter body for rotation relative thereto. A chip accommodating chamber is defined between an inner peripheral surface of the cover unit and the outer peripheral surface of the cutter body. A suction port unit is provided in the wall of the cover unit and communicates with the chip accommodating chamber. A chip guide unit is arranged at the forward end of the cutter body in facing relation to the face of the cutting tip for guiding the chips generated by the cutting tip to the chip accommodating chamber.

    摘要： There is disclosed a ball end mill which has a hemishepherical portion formed at a front end of an end mill body. A pair of tip mounting seats are formed at the hemishepherical portion. A main throw-away tip and a second throw-away tip are secured on the tip mounting seat respectively such that the axial rake angle of the main tip is set at a negative angle and the axial rake angle of the second tip is set at a positive angle. There is also disclosed a second ball end mill. In the second ball end mill, only a main throw-away tip is secured on a tip mounting seat. The axial rake angle of the main tip is set at a negative angle. One or more chip breaker grooves are formed on a rake face of the tip.

    摘要： A cutter insert for a ball end mill is disclosed which includes a plate-like insert body having a front face and a side face extending from the front face. The front face has a generally convexly curved marginal ridge defined by the intersection of the front face with the side face. The marginal ridge serves as a cutting edge. The front face serves as a rake surface for the cutting edge while the side face serves as a relief surface for the cutting edge. The cutting edge has a leading portion to be indexed in the end cutting position and a trailing portion to be indexed in the peripheral cutting position. A land is formed on the rake surface so as to extend along the cutting edge. The land has a width gradually increasing in a direction from the leading portion of the cutting edge toward the trailing portion thereof.

    摘要： A digital camera stores captured picture data and E-mail address data inputted from a key entry unit in a flash memory so that they are associated with each other and then transfers the picture data and the E-mail address data to a personal computer via an I/O port or an infrared communication unit. The personal computer receives the picture data and the E-mail address data transferred from the digital camera via an I/O port or an infrared communication unit. The received picture data is then transmitted to a destination terminal on a computer network on the basis of the received E-mail address data.

    摘要： A cutting insert wherein cutting edges are formed on a pair of ridge portions of an upper surface and a pair of ridge portions on a lower surface in a staggered position relative to the ridge portions of the upper surface in a direction along the peripheries of the upper and lower surfaces. Rakes are formed on side surfaces of the insert body connecting to the cutting edges. Each rake has an inclination such as to be closer to a center of the upper or lower surface at a position remoter from the corresponding cutting edge. Each rake is formed of a curved surface which is formed along the side connecting to the cutting edge and which is curved along the peripheral direction so as to round out in an outward direction from the insert body, and a flat surface which obtusely intersects the curved surface and connect to a ridge portion opposite from the cutting edge formed along on the side of the rake. The positions and the shapes of the curved surface portions and the cutting edges are determined on the basis of the flat surfaces and the upper and lower surfaces. The insert can be prevented from shifting and the working accuracy can be improved by accurately forming the cutting edges and other portions.

    摘要： A throw-away cutting tool is disclosed. The tool body of the cutting tool consists of a rod-like shank and a bit mounting component arranged at the front end of the shank. The shank is made of cemented carbide, and is formed with a mounting wall extending toward the front end of the tool body. The bit mounting component is made of steel or sintered metal, and is formed with a bit mounting seat defined by a bottom wall and side walls. In the above cutting tool, high resistance against the cutting force produced by cutting operation can be obtained and separation of the shank and the bit mounting component can be prevented; and high rigidity of the tool body is ensured, the damping capacity of the tool body is increased, and therefore vibration and chatter of the cutting tool can be effectively prevented.
