    摘要： A METHOD OF FORMING A TUBE REDUCING TOOL COMPRISING THE STEP OF FORMING A TOOL BLANK OF STEEL HAVING A ROLL PORTION AND DRIVE SHAFT PORTION. THE ROLL PORTION IS PROCESSED TO FORM A SERIES OF SPACED ROLL BLANKS ALONG THE LENGTH OF THE TOOL WHICH IS THEN HEAT TREATED TO A HARDENED STATE. THEREAFTER, ELECTRODES ARE POSITIONED IN THE LATERAL TANGENCY TO AND GENERALLY BESIDE THE STELL ROLL BLANKS TO BE MACHINED. THE ELECTRODES ARE THEN CAUSED TO EMIT AN ELECTRICAL SPARK DISCHARGE WHILE CAUSING A TANGENTIAL SURFACE OF THE ROLL BLANKS TO MOVE ALONG THE LENGTH OF THE ELECTRODES ESTABLISHING A CUTTING ZONE ALONG THE TANGETIAL SURFACES OPPOSED TO THE ELECTRODES FORMING TAPERED GROOVES EXTENDING GENERALLY IN ARCUATE DIRECTIONS THEREIN.

    摘要： Provided is a cutting insert configured to be able to realize downsizing of a cutting tool. A cutting insert includes: an upper surface and a lower surface facing each other and having a plurality of corner parts; a side surface connecting the upper surface and the lower surface and forming intersecting edges with the upper surface and the lower surface, respectively; and a through hole that has a central axis extending from the upper surface to the lower surface and that is formed for penetration from the upper surface to the lower surface. A corner cutting edge arranged at a position corresponding to a corner part of the upper surface, a minor cutting edge connected to a first end of the corner cutting edge, and a major cutting edge connected to a second end of the corner cutting edge are formed on the intersecting edge between the upper surface and the side surface. A flank of the corner cutting edge and a recessed part located on the lower surface side of the flank of the corner cutting edge are formed on the side surface.

    摘要： An improved solid cemented carbide ball nose end mill is provided which enables a cutting of a quenched or hardened difficult-to-machine material without any chipping or break of edge under the condition of a high speed and high load cutting. The improved end mill comprises a substantially semi-spherical ball nose portion provided with such cutting edges as to form a virtually S-shaped symmetrical configuration as viewed from the tip end and a tool body integral with said ball nose portion and having a peripheral cylindrical portion being provided with no peripheral cutting edge and a shank at the rear end thereof. The cutting edges extending from the tip end of the ball nose portion to the respective terminals positioned at the furthest at the vicinity of the border between the ball nose portion and the tool body are formed in the ball nose portion only. Preferably, each of a rake angle and a relief angle of the cutting edge is set between 0.degree. and -10.degree., and between 6.degree. and 16.degree., respectively, further the cutting edges are coated with a titanium-aluminum nitride based material film.

    摘要： A milling tool includes a tool body having a longitudinal axis and a first end. A plurality of flutes are provided in the tool body and extend to the first end of the tool body. A plurality of cutting edges are provided. Each cutting edge is associated with a respective one of the plurality of flutes, each cutting edge being substantially identical to each other one of the plurality of cutting edges except that at least one but not all of the cutting edges is a recessed cutting edge and at least one but not all of the cutting edges is a non-recessed cutting edge. Each recessed cutting edge begins at a non-zero distance from the first end of the tool body and each non-recessed cutting edge extends to the first end of the tool body.
