摘要： The present invention relates to a honing method and apparatus which provides greater control over the edge shape, as well as reductions in the effort required to hone multiple edges on workpieces. The invention accomplishes these improvements by controlling the speed of the abrasive wheel, as well as the orientation and position of the workpiece prior to and/or while it is in contact with the abrasive brush. This provides for greater control over the hone shape, hone size, and hone distribution along all the cutting edges of the tool.
摘要翻译：本发明涉及一种珩磨方法和装置，其提供对边缘形状的更大控制，以及削减在工件上磨削多个边缘所需的努力。本发明通过控制砂轮的速度以及工件在与研磨刷接触之前和/或之间的取向和位置来实现这些改进。这提供了对刀具的所有切削刃的磨削形状，磨削尺寸和磨削分布的更好的控制。

摘要： A throw-away tip comprises a tip body with a rake face and a flank face; a generally plane chamfered surface formed at and along a cutting-edge-forming ridge where the rake face and the flank face cross each other; and a phantom radius surface formed at a crossing ridge between the chamfered surface and the flank face, the phantom radius surface being constituted, as in section perpendicular to the cutting-edge-forming ridge, by a plurality of lines connected to one another to provide a generally convex shape. A throw-away tip is provided which has an improved wear resistance and a tough cutting edge, prevents occurrence of fins, and enables suppression of chipping and breaking.

摘要： Fluid passageways are defined by the top plate, tool holder body and the cutting insert to permit the optimum cooling of the interface between the insert and the work piece reducing degradation of the cutting edge of the insert. A number of top plate designs with channel configurations are disclosed to provide the desired coolant flow distribution and accommodate the desired flow rate.

摘要： A cutting insert for a metalworking operation includes a polygonal body of hard wear resistant material. The body has a top surface and a bottom surface, and therebetween a peripheral wall including adjacent first and second wall portions. The intersection of the first wall portion and the top surface forms a first cutting edge, and the intersection of the second wall portion and the top surface forms a second cutting edge. The first cutting edge and the second cutting edge meet to form a high point which is adapted to engage a workpiece first during the metalworking operation. In one embodiment, the top surface of the cutting insert has a topography that promotes chip control. The topography includes a plain adjacent to the cutting edges, and a plateau on the plain, which is, located inward from the cutting edges. The plateau is elevated relative to the plain and has a sloped side.

摘要： An indexable insert having a tip body formed of a polygonal flat plate. An upper surface of the tip body serves as a rake face, and edges are formed along ridges defined by sides of the rake face. Nose portion edges are formed at corners of the rake face at which the edges adjacent to each other intersect. The nose portion edges each have a rake angle varied between both ends of the nose portion edge.

摘要： A cutting insert comprises a rake face, a plurality of flank faces including clearance faces having a positive clearance angle. A cutting edge is formed at an intersection between the rake faces and the flank face and a convex wiper cutting edge formed on the cutting edge. A method for forming the cutting insert comprises the steps of placing a powdered material into a die and pressing the powdered material in the die to achieve a form having a convex portion on the rake face and at least one substantially flat clearance face having a positive clearance angle. Next, the form is removed from the die and sintered.

摘要： A double negative cutting insert has opposite top and bottom sides between which transverse flank surfaces extend, adjacent to which cutting edges are formed. There are at least four useful major cutting edges, which separately extend from an active operating corner towards a nearby first inactive corner. Each major cutting edge co-operates with a minor cutting edge with the purpose of face machining the surface, that is left after material removal. The cutting insert has an octagonal basic shape, the top and bottom sides thereof having an identical shape with four spaced-apart supporting projections, which are placed near the four inactive corners and have plane abutment surfaces located in a common plane. An individual land adjacent to the major cutting edges has a concavely arched shape in order to provide a positive cutting geometry during operation.

摘要： An indexable insert for metal cutting having an upper surface, a bottom surface and side surfaces. At least a portion of the intersecting lines between the side surfaces and the upper surface generates a main cutting edge, a secondary cutting edge and a corner cutting edge. The corner portions of the upper side are provided with recesses. The corner cutting edge including at least two radiused edges having different radii. The first radiused edge, having a larger radius, being located adjacent to the main cutting edge and a second radiused edge, having a smaller radius, being located adjacent to the secondary cutting edge. Furthermore, the secondary cutting edge includes a radiused edge having a larger radius than the two aforementioned corner radiused edges and the recess includes a rear plane being so arranged that the chips hit a rear plane of the upper surface and break against the rear plane.
