20120061924 | TOOL HOLDER FOR USE IN A MACHINE TOOL AND METHOD FOR OPERATING SUCH A TOOL HOLDER - A tool holder has a first holder part for inserting into a receptacle in the machine tool and a second holder part for holding a tool. The tool holder has a conduit for directing a coolant and/or lubricant to the tool from a coolant and/or lubricant source. The tool has a conduit section for the coolant and/or lubricant for directing the latter to a machining point, and wherein, in the fitted state of the tool in the tool holder, the conduit is in contact with the conduit section at a coupling point. Provision is made for there to be an air feed line which directs compressed air from a compressed-air source into the region of the coupling point in such a way that the compressed air acts on the outer circumferential surface of the conduit and of the conduit section. Furthermore, methods for operating such a tool holder are described. | 03-15-2012 |
20120014760 | Modular Drill - The invention relates to a modular drill including a shank part with an end side. A cutting part can be connected to the shank part at its end side. The shank part has at least one torque transmission element which projects on the end side and has at least one torque transmission face for transmitting a torque in the rotational direction from the shank part to the cutting part. The cutting part has at least one torque receiving region for receiving the torque. The at least one torque receiving region has at least one torque receiving face which corresponds with the torque transmission face. The cutting part has at least one centering element for radially centering the cutting part in relation to the shank part. The cutting part is clamped to the shank part via a clamping element which acts at least predominantly in the axial direction. | 01-19-2012 |
20110211925 | Method for Generating a Thread by a Tool machine, Coupling Device and Tool Machine - The invention relates to a method for generating a thread by a numerically-controlled tool machine (or: machine tool) using a thread generation tool, the thread generation tool being rotated by a tool spindle and simultaneously advanced according to the thread pitch in the axial direction, in order to generate a thread in a borehole of a workpiece. In order to increase the working velocity of the thread generation, the invention provides that the rotational velocity (ω | 09-01-2011 |
