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 |
20100031799 | Method and Tool for Producing a Surface of Predetermined Roughness - For producing a cylindrical surface that has a surface structure of predetermined geometry suitable for application of material by thermal spraying, a geometrically predetermined groove structure of minimal depth and width is introduced into the surface by a tool embodied as a follow-on tool in that a groove cross-section is processed successively to a final size. In order for the surface to be producible in mass production with constant quality, the groove structure is worked in such that first a base groove is introduced with a groove bottom width that is smaller than the groove bottom width of the finished groove. Subsequently, at least one flank of the base groove is processed for producing an undercut groove profile by a non-cutting action or cutting action wherein the introduced groove structure is deformed in such a way that the groove openings are constricted by upsetting deformations of material. | 02-11-2010 |
20120082523 | ROTATIONALLY DRIVEN MULTI-BEVEL STEP TOOL - The invention relates to a rotationally driven multi-bevel step tool, particularly a step drill for drilling into solid material, comprising a plurality of one-edged or multi-edged cutting steps which are arranged in a staggered manner in the cutting and advancing directions and each have a number of flutes that corresponds to the number of edges. Flutes ( | 04-05-2012 |
20120189397 | DEVICE FOR SEALING - The application describes a device for sealing a coolant and/or lubricant channel, wherein the coolant and/or lubricant channel extends through a first tool part, a second tool part, and the device, wherein the device comprises a first section, a second section, and a center section. The first section can be connected to the first tool part. The second section is arranged in such a way that the second section can protrude into the coolant and/or lubricant channel of the second tool part, wherein the outer diameter of the second section is greater than or equal to the inner diameter of the coolant and/or lubricant channel of the second tool part. The center section is arranged between the first section and the second section. | 07-26-2012 |
20120321402 | MULTI-BLADE CUTTING AND DRILLING FINISHING TOOL - Described is a multi-blade cutting and drilling finishing tool, in particular a reamer, for machining deep, especially stepped bores. Said tool comprises a set of blades having a predetermined nominal diameter and blades that are distributed in a substantially regular manner along the circumference. In order to make it easier to guide the tool along the central axis, a set of guiding strips in the form of very accurately placed and preferably cylindrically ground cutting inserts is located behind the set of blades in the advancing direction. Each of said cutting inserts is axially flush with the blades of the adjacent set of blades in the advancing direction of the tool and has a nominal diameter which is smaller than the nominal diameter of the set of blades substantially by twice the size of a lubrication gap forming when the tool is used. | 12-20-2012 |
20130045059 | FACE MILLER AND USE THEREOF - The face miller is equipped with a plurality of plate-shaped hard material cutting inserts that are distributed over the circumference. The hard material cutting inserts are located on a graduated circle in pockets of a blade carrier and have a main cutting edge, which is adjusted at a cutting edge angle smaller than 90° relative to the working plane of the miller. In order to ensure maximum machining performance at a good service life, the cutting edge angle is selected to range between 10° and 30°, wherein the main cutting edge at the same time has a slightly convex design. The main cutting edge transitions into the secondary cutting edge via a transition radius having a value that ranges between 0.5 and 1.5 mm. The axial rake angle ranges between 20 and 30°. According to an advantageous further development, the radial rake angle ranges between −6° and −10°. | 02-21-2013 |
20130084141 | ROTATABLE CUTTING TOOL - An expanding tool comprising: an outer cone for radially expanding a portion of a cutting head, wherein the portion has a cutting edge for machining a workpiece. Furthermore, the description shows a rotatable cutting tool for machining a workpiece, wherein the cutting tool comprises: a cutting head with a recess, wherein the recess has a portion which is formed as an inner cone. | 04-04-2013 |
20130089385 | COLLET CHUCK - The description shows a collet chuck 303 for clamping a tool for the purpose of machining a workpiece, comprising: a cutout for receiving a collet 301, wherein the collet chuck 303 has a cutting edge 306 for machining the workpiece. | 04-11-2013 |
20130164089 | DRILLING TOOL - The invention relates to a drilling tool comprising a clamping shaft and cutting element contiguous with said clamping shaft. The cutting element comprises at least one flute having a flute surface that has a concave cross-section. The at least one flute has a cut-in section in the chip-forming zone adjacent to the main cutting edge in the area of the flute front and/or the back segment to enlarge the flute cross-section. | 06-27-2013 |
