| 20080206001 | CUTTING TOOL - A tool for cutting machining, such as drilling, milling, or friction machining preferably includes a tool head, and a tool shaft having a clamping section for housing in a tool support. The tool head includes a plurality of tool cutting edges that are arranged circumferentially about the tool head and that consist of the material of the tool head. The tool head can be fitted to the to the tool shaft as a separate part or can be intregally formed as part of the tool shaft. The tool head consists of, in one piece, a hard material and at least one functional layer comprising cubic boron nitride or polycrystalline diamond. | 08-28-2008 |
| 20080240869 | Reverse tipped router bit - A router bit with an elongate body having a shank end and a cutter element support head. The shank end projects outwardly from the body to facilitate mounting the router bit on a rotating machine, and the cutter element support head extends in the opposite direction from the shank end and has an axis of rotation (A) which is coaxial with the shank. The cutter element support head is formed with two flutes in a diametrically opposed relation, each flute having an outer surface and a cut-away inner surface with a groove being formed in the outer surface of the flute along the longitudinal length of the cutter element support head. An elongate cutter element is affixed in the longitudinal groove of each flute. The cutter elements are configured such that they form a hook angle (α) that is greater than or equal to 35 degrees. | 10-02-2008 |
| 20090245946 | CUBIC BORON NITRIDE RADIUS END MILL - A cubic boron nitride radius end mill includes a sintered cubic boron nitride compact bonded to an end of a main body, and a cutting edge provided on the sintered cubic boron nitride compact. The wedge angle θt of the cutting edge is constant over the entire region of the cutting edge. A negative rake face is disposed on a face so as to extend over the entire region of the cutting edge, and the rake angle θn of the negative rake face satisfies the relationship −30°≦θn≦−50°. A joint cutting edge is disposed between an end cutting edge and a radius cutting edge in the cutting edge, the joint cutting edge having a concave angle γ0 which is smaller than the concave angle γ1 of the end cutting edge and which satisfies the relationship 0.5°≦γ0 ≦2°. | 10-01-2009 |
| 20100014927 | INCREASED PROCESS DAMPING VIA MASS REDUCTION FOR HIGH PERFORMANCE MILLING - A cutting tool incorporates a body terminating in cutting edges distal from a chuck mount and having an axial bore for reduced mass to raise the natural frequency of the tool. In certain of the embodiments, the body is preformed from a steel or carbide blank into a cylindrical pipe forming the hollow bore prior to grinding of the cutting edges. Filling of the bore with a light weight polymer to further absorb vibration can also be employed. | 01-21-2010 |
| 20100290845 | CARBIDE ROTARY TOOL - A cutting edge portion intermediate form that is a pre-sintered body of the cutting edge portion and a supporting portion intermediate form that is a fully sintered body of the supporting portion are manufactured separately. Full sintering is then performed where front end portion of the supporting portion intermediate form is inserted into an insertion hole of the cutting edge portion intermediate form. During sintering, cobalt particles in powdered materials are converted into a liquid phase, and contracting occurs. Because the supporting portion intermediate form has already been fully sintered, only the cutting edge portion intermediate form contracts. The front end portion of the supporting portion intermediate form is squeezed by the cutting edge portion intermediate form. The carbide tip is therefore created in which the cutting edge portion and the supporting portion are strongly bonded. | 11-18-2010 |
| 20110020079 | COATING PROCESS, WORKPIECE OR TOOL AND ITS USE - The invention relates to a process for coating a substrate composed of cemented carbide, a cermet, steel or ceramic with at least one Ti | 01-27-2011 |
| 20110188950 | COATED CUTTING TOOL AND A METHOD OF MAKING THEREOF - The present invention relates to a cutting tool for metal machining with improved wear properties, comprising a cutting tool substrate of cemented carbide, cermet, ceramics or a super hard material, and a wear resistant coating, wherein the wear resistant coating comprises a PVD Ti—Si—C—N layer with a compositional gradient, and a method of making thereof. | 08-04-2011 |
| 20130209183 | FABRICATION METHOD FOR DIAMOND FILM COATING OF DRILL BIT - Tungsten carbide drill bits for removing material from alloys and other hard materials are disclosed. A conventional drill bit is modified by removing material from the forward portion of the bit to increase the radius of the cutting edge. The drill bit is then coated with a nanostructured diamond film using a chemical vapor deposition process. | 08-15-2013 |
| 20130236254 | TWO-MATERIAL ONE-PIECE CUTTING TOOL - The invention relates to a cutting tool, more particularly to a monobloc carbide cutter comprising a rod shrunk within the body of the cutter and extending to the so-called front end of the cutter having cutting edges. The shrunken rod enables bending vibrations to be damped through friction. Each cutting edge is formed directly and continuously from the material of the rod and the material of the body. As those parts of the cutting edges formed in the material of the rod rotate at lower speeds than those parts formed in the material of the body, the material of the rod can have cutting speed performance lower than that of the material of the body. | 09-12-2013 |
| 20130315680 | MILLING CUTTER FOR HARD MACHINING - The invention relates to a milling tool (1) having a length I | 11-28-2013 |
| 20140169891 | Tool For The Cutting Machining Of Workpieces And Process For Coating Substrate Bodies - The invention relates to a tool having at least one layer of Ti | 06-19-2014 |
