Abstract: Reducer sleeves are described herein. Reducer sleeves described herein comprise a reducer sleeve body having an axial forward end and an axial rearward end. The reducer sleeve body defines a longitudinal axis. Reducer sleeves further comprise a flange disposed at the axial forward end of the reducer sleeve body. The flange defines a first nozzle disposed at a first radial distance from the longitudinal axis and a second nozzle disposed at a second distance from the longitudinal axis. The reducer sleeve body defines a first trough extending from the axial rearward end to the axial forward end. The first trough is in communication with the first nozzle and the second nozzle, whereby coolant is able to enter the first trough and flow along the first trough and into the first nozzle and the second nozzle such that the coolant is ejected by the first nozzle and the second nozzle.

Abstract: A reducing sleeve for fastening a machining tool in a tool holder is described. The reducing sleeve includes a reducing sleeve body, which has a first tool-side end and a second tool holder-side end. In addition, at least one coolant supply channel is provided in the reducing sleeve body. In one embodiment, a safety unit with a pull-out safety geometry has a sealing element, such as an O-ring, to selectively direct coolant through coolant holes in the safety unit and the at least one coolant supply channel or alternatively through a central coolant channel. In this embodiment, a multifunctional interface, and additional O-ring and a sealing unit are not required. A modular reducing sleeve assembly includes a reducing sleeve and a safety unit as separate parts. In addition, a machining assembly including a tool holder, a reducing sleeve, and a machining tool is described.

Abstract: The invention relates to a sealing piston, which is designed for use in a hydraulic expansion chucking device. The sealing piston comprises a pin that extends in an axial direction (A), and a seal that adjoins the pin and likewise extends in said axial direction (A). The seal comprises a sealing shaft that adjoins the pin and has a shaft radius (Rs). The seal further comprises a sealing head that adjoins the sealing shaft, wherein the sealing head comprises a circumferential sealing lip, which has a sealing radius (Rd) that is greater than the shaft radius (Rs). The sealing lip forms a contact surface in radial direction (R) for abutment and sealing against an inner wall of a bore in the expansion chucking device, and, measured in axial direction (A), has a sealing length (Ld) that is greater than the difference between the sealing radius (Rd) and the shaft radius (Rs). The invention further relates to a corresponding expansion chucking device.
