摘要： A facing head as well as a method for inserting a tool into and/or removing a tool from a tool holder device of the facing head. The facing head has a spindle coupling device for exchangeably coupling with a spindle chuck of a working spindle of a machine tool. The facing head has a housing body at which or in which a facing slide is moveably supported in a guided manner. The facing slide supports the tool holder device. The tool holder device is hydraulically controllable. A hydraulic coupling that is mechanically and hydraulically coupled with an associated hydraulic control coupling of the housing body in a tool change position of the facing slide. Remote from the tool change position, the mechanical and hydraulic connection between the hydraulic coupling and the associated hydraulic control coupling is interrupted. In the tool change position a switching of the tool holder device between a hold condition holding the tool and a release condition releasing the tool can be carried out by a respective pressurization with hydraulic pressure.

摘要： The invention relates to a clamping apparatus (1) for clamping a workpiece (100), which is or is to be toothed and has an axis of rotation, onto a spindle, which can be rotationally driven and has a spindle axis defining an axial direction (A), with a clamping mechanism (20), which converts an axial force (FA) transferred via a force transfer device (10) into a clamping force (Fg) directed radially to the spindle axis, wherein the force transfer device (10) has a first section (12) movably guided by a guide arrangement (30) in relation to a movement having an axial direction component, wherein the first section (12) is segmented into several transfer elements (12a, 12b, 12c, 12d) spaced apart from one another in a circumferential direction.

摘要： An expander unit of a cryogenic refrigerator device includes a moving assembly with a porous regenerative heat exchanger configured to move back and forth along a longitudinal axis. A magnetic spring assembly includes a stationary magnetic assembly fixed to the cold finger base that includes one or more magnetic rings fixedly arranged about a bore. A movable magnetic assembly includes one or more movable magnetic rings fixed to the moving assembly. An outer lateral dimension of each of the movable magnetic rings is less than an inner lateral dimension of the bore. The stationary magnetic assembly and the movable magnetic assembly are configured such that, when the moving assembly is displaced along the longitudinal axis from an equilibrium position, attractive and repulsive forces between the movable magnetic assembly and the stationary magnetic assembly yield a restoring force that is directed to restore the moving assembly to the equilibrium position.

摘要： An adjustable collet holder for use with a lathe is provided. The adjustable collet holder may include a set of hold down screws to hold it in place once adjusted. Adjustment may be achieved by adjusting multiple set screws to change both angular and concentricity orientations of a collet receiver relative to a body of the collet holder.

摘要： A chuck grip accuracy checking method includes a gripping in which the measurement target is gripped on the claws, a moving step, and a measuring step. In the moving step, a movable member provided with a measurement instrument capable of measuring a run-out of the measurement target is moved by driving a movable-member driver to a position at which the measurement instrument can measure a run-out of the measurement target. In the measuring step, a run-out of the measurement target is measured by the measurement instrument, while the chuck is being rotated by driving a rotation driver.

摘要： A tool holder includes a main body, a deformable receptacle for clamping a tool, and at least one blocking element which, in order to prevent axial migration of the tool out of the tool holder, is configured to engage in a corresponding counterpart element on the tool and is arranged at the receptacle. In order to allow particularly high concentricity of the tool holder and stable fastening of the clamped-in tool, and at the same time to ensure easy production, the receptacle has two spaced-apart clamping portions, between which the at least one blocking element is arranged.

摘要： The present invention provides a rigid modular holding with axial and radial compensation for multiple and universal application of all machining processes, engineering, machine building, and construction fields where ever applicable for rotary and static systems. Design of modular holding includes male and female portions (401,301) of joining parts machined to the required shape and clearances to accommodate modular locking rigidly with face butting (407, 308). Radial and axial run out adjustments is controlled by the grub screws (307, 306) and run out compensation can be achieved within micron. An Area used for clamping and designed within the area of joining parts results reduction in material and processing cost. Since, the material is not protruding out from the surface of the joining parts, esthetically looks good and convenient for designing multiple applications as it is not possible at present.

摘要： Disclosed is a tool system including a drive for driving a tool holder including an electromagnetic generator for generating electrical energy from inertial energy of the tool holder. The tool holder may be driven in rotation, wherein the electromagnetic generator comprises a rotor part, which is rotatably mounted on the tool holder, and a stator part on the tool holder cooperating with each other for generating a voltage by electromagnetic induction. Alternatively, an axially movable inertial mass can be used for utilization of an oscillating linear movement.

摘要： 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.
