Abstract:
A tool holder for non-positively holding a rotatable tool by a receiving body containing a receiving opening with slits extending radially from the inner wall towards the exterior and running in the longitudinal direction of the receiving body. To permit a simple production process, the receiving body has an insert fixed into a receiving section.
Abstract:
The induction coil unit for heating a component that is rotationally symmetrical relative to an axis (7), in particular a tool holder (5), comprises a plurality of coils (19) arranged about the axis (7) of the tool holder (5) with pole elements, which are movable radially with respect to the axis (7), which are connected to one another by a common yoke ring (17). Upon excitation of the coils (19) with alternating current, the latter produce a magnetic flux running in the peripheral direction in the tool holder (5) for the inductive heating of the tool holder (5). The induction coil unit (1) can be moved in an oscillating manner by means of a drive (87) in the direction of the axis (7), the pole elements (21) moving in an oscillating manner along the tool holder (5). An induction coil unit of this type is in a position to heat a comparatively large region of the tool holder (5) despite a comparatively small energy requirement and comparatively small dimensions.
Abstract:
A balancing or measuring adapter, which includes a main body having a holder for the component to be balanced or measured and a clamping device assigned to the main body having a movable clamping element for clamping the component to the main body and releasing it therefrom. A braking device for generating a constant advance speed of the clamping element as it moves is arranged on the movable clamping element for precisely positioned clamping and jerk-free release of the component.
Abstract:
The invention relates to a tool holding device comprising a tool holding body for securing, in a fixed manner, a rotary tool comprising a shaft, provided with a clamping section and a receiving opening for the shall of the tool, a coolant feeding device for pressurized fluid, at least one coolant guiding device for guiding the coolant into a clamped tool shaft. The coolant guiding device is designed as at least one flat groove on an inner side of the receiving opening, joining to the front side on a free end of the tool holding body and directly adjacent to the tool shaft in the surroundings of the tool holding device or a coolant storing chamber and or collecting chamber is provided in the region of the free end of the tool holding body, to which the at least one coolant guiding device joins. The coolant storing chamber and or collecting chamber is connected by means of an annular gap to the surroundings of the tool holder device. The coolant storing chamber and/or collecting chamber and the annular gap are defined at least partially by the work shaft.
Abstract:
A collet chuck with a chuck body, a collet, and a clamping nut in which the chuck body has a coupling section for coupling the collet chuck to the working spindle of a machine tool and has a collet holder embodied in the form of an inner cone and at least one thread groove for the screwing-on of the clamping nut; the collet has an outer cone, which is complementary to this inner cone, as well as a cylindrical tool holder; the collet chuck is embodied so that by tightening the clamping nut, the collet can be driven far enough into the collet holder that the tool shaft is held in a rotationally secured fashion; and the clamping nut has at least one thread groove; where rolling elements are inserted between the thread grooves of the chuck body and the clamping nut so that the clamping nut and the chuck body constitute a rolling element screw drive.
Abstract:
A tool holder with a main part, a deformable receiving portion for clamping a tool, and at least one blocking element which is designed to engage into a corresponding counter element on the tool in order to prevent the tool from moving axially out of the tool holder. The at least one blocking element is integrally formed with the receiving portion. A clamping system having such a tool holder and a method for producing a receiving portion for such a tool holder are also described.
Abstract:
The invention relates to a tool holder (1) for clamping tools by shrink fit. The tool holder, due to its specific shaping in the area of the shrink-fit head (6) and the shrink-fit base (5) of the tool holder, is less prone to oscillate than known tool holders, therefore allowing inter alia higher speeds so that the cutting capacity, determined by the speed of the tool, the tool feed and the cutting depth of the tool, can be increased and the machine running times required to produce a workpiece can be reduced. The tool holder (1) of the present invention allows to produce and machine workpieces in a substantially more efficient and economical manner.
Abstract:
The invention relates to a device for drying a work piece, preferably in the form of a shrink fit chuck, that has previously been subjected to an application of a liquid and is essentially rotationally symmetrical around a longitudinal axis of the work piece; the device has at least one air-conducting device that encompasses the work piece in order to convey an air flow in the direction along the longitudinal axis of the work piece and has at least one blower device that directs a radial air flow at the work piece.
Abstract:
The present invention relates to a low-vibration tool holder (1) with a tool holder base body (2, 3, 4, 6) and a tensioning arrangement (5) which provides axial tensioning of the tool holder base body (2, 3, 4, 6) and which is simultaneously tensioned in a radially flexible way with respect to the tool holder base body (2, 3, 4, 6). This tool holder (1) is less susceptible to vibration than previously known tool holders, which ensures better true running even during operation and in particular when heat-induced expansion of materials occurs, since the clamping arrangement (5) which is integrated in the tool holder (1) is continuously centered with respect to the tool holder base body (2, 3, 4, 6). Furthermore, such a tool holder (1), in particular within a modular design, can be adapted very flexibly to different types of tools and workpiece machining processes.
Abstract:
The invention relates to a device for cooling an object that was previously subjected to a heat application, generally a multi-piece composite, particularly in the form of a shrink-fit chuck into which the shank of a tool was chucked or from which it was removed (cooling device), wherein the device comprises a pump, by way of which it generates a carrier gas flow, particularly an air flow, which is charged with a liquid cooling medium, particularly water, so that a coolant flow, the majority of the volume of which consists of the carrier gas, is created, which then spreads over at least the section of the object to be cooled.
