    Abstract: The present invention concerns a method for sharpening a worn removable machining tip (3) and the corresponding sharpened tip. The tip having a first cutting edge (7) damaged after a first use (u1), said tip having, in the state prior to the use of same, specific dimensional and geometrical parameters within a defined tolerance range and said first undamaged cutting edge (7) having a defined sharpness, the method involves sharpening the cutting face (9) by removing material from said cutting face on said first damaged edge (7), in order to make said tip (3) match said specific dimensional and geometrical parameters within said defined tolerance range, having a second cutting edge (7′) of said defined sharpness.

    Abstract: A method for manufacturing a cubic boron nitride cutting tool including a base metal and sintered cubic boron nitride compact at a corner portion of the base metal, capable of improving the accuracy of the center height and reducing the angle of inclination or width of a negative rake face; and the cubic boron nitride cutting tool. The method includes grinding the compact by pressing it against an end face of a grindstone of a grinder to form flank and rake faces on the compact while the base metal of the cutting tool is held by a chuck of the grinder, so that the compact is substantially ground. The rake face is formed to be recessed from a top face of the base metal or only a portion of the compact that protrudes from a base-metal rake face is ground while the tool is continuously held by the chuck.

    Abstract: A knife and scissors sharpener with a guard for the former. The scissors sharpener has an opening for each blade of the scissors with a cylindrical sharpening stone extending across them. The stone may rotate about an axis perpendicular to the openings to allow its positioning parallel to the cutting edges of the scissors to effectuate the sharpening of the blades. A spring normally keeps the cylindrical stone in one position, but the force exerted on the scissors' handles will cause the stone to move to its proper orientation. The knife sharpener employs two tungsten carbide sharpening elements crossed to form two V's. The sharpening elements in one V have a configuration for effectuating knife sharpening. In the other V, the elements will hone a previously sharpened knife blade. A circular disk holds the crossed sharpening elements in the handle. Rotating the holder 180.degree. permits a change between the sharpener and the honer. A guard attaches to the holder and can rotate between opened and closed positions. In the open position, it permits the use of the sharpener and honer. To use either of these involves holding the edge of the entire mechanism on a surface. In its open configuration, the guard drops down and protects the surface from a knife undergoing sharpening. In its closed position, it rotates up against the holder so that it will occupy minimal additional space.

    Abstract: A method of treating a cutting edge of a tool to reduce deterioration of the cutting edge during a subsequent machining operation. A brush having a plurality of bristles is rotated about an axis of rotation and positioned relative to the cutting edge whereby the brush axis is oriented perpendicular to the cutting edge or at an angle of up to about plus/minus 20 degrees with respect to the perpendicular orientation. The brush is then brought into contact with the cutting tool in the presence of an abrasive material. Preferably the cutting tool is a cutting blade for cutting toothed articles such as gears and the like wherein the cutting edge is formed by the intersection of a front face and a cutting side profile surface of the cutting blade. The rotating brush effectively polishes a portion of the front face and cutting side profile surface which is adjacent to the cutting edge while producing the rounding-off of the cutting edge.

    Abstract: An apparatus for producing or forming surfaces at the cutter blade head portion of a cutter blade formed of hardened steel. The hardened steel blades, provided with a cutter blade head portion, are contemplated to be used in the cutter head of a gear cutting machine. In order to form the surfaces of the cutter blade head in a relatively short amount of time, without impermissible heating of the cutter blade steel, there is formed during a first step a pre-profile of the blade head by means of a cutting-off device containing a cutting-off grinding disk. During a further step the preformed surfaces of the pre-profile are ground into cutter blade surfaces at the heretofore conventionally used grinding machine. The apparatus for performing the method contains a rotatable hearing or support unit, adjustable into different positions, in which there is mounted the cutting-off grinding disk.
