A horizontal machining lathe with a shock-absorbing braking mechanism includes a lathe body including a lathe bed, a chuck, a spindle box, and a slide box. The chuck is arranged on an output end of the spindle box. The lathe bed is provided with the spindle box at one end of and a tailstock base at the other end. The lathe bed is provided with a guide rail, and the slide box is provided with a tool holder assembly. An end of the inner shaft proximate to the chuck is provided with a brake disc, and the spindle box is provided with a spindle braking device including first and second brake devices symmetrically arranged on both sides of the brake disc and a reset device arranged therebetween.

A device is represented and described for machining, in particular for deep-rolling, shafts and other components, including two live centres for receiving a shaft to be machined on both sides, at least one drive for rotating the shaft to be machined, at least one pair of rolling tools for machining, in particular deep-rolling the shaft to be machined. The two live centres are arranged on a central axis, wherein at least one live centre is displaceable along the central axis. At least one pair of rolling tools is arranged on a movable axial slide, which is displaceable along the central axis. The rolling tools are displaceable in the radial direction relative to the central axis. In order to achieve efficient machining of components with different geometries, at least one changing apparatus is provided for changing the rolling tools. The use of a device of this type for deep-rolling shafts, in particular wheelset shafts of wheelsets for rail vehicles, is also represented and described.

A workpiece transfer device includes a base unit extending in a first direction, a housing unit disposed upright from the base unit in a second direction orthogonal to the first direction, a slide unit disposed at a housed position to be housed in the housing unit, a slide unit-moving mechanism configured to move the slide unit from the housed position, a linear guide unit configured to guide the slide unit in the second direction, and a workpiece grasp unit disposed on a first surface of the slide unit near an end of the slide unit remote from the base unit and configured to grasp a workpiece W. A separation distance between the base unit and an end of the workpiece grasp unit adjacent to the base unit is less than a separation distance between the base unit and the end of the slide unit remote from the base unit.

A material bar magazine for guiding material bars on an automatic lathe and a system having such a magazine and automatic lathe having at least one headstock that is displaceable along a longitudinal axis of the material bar magazine, where the material bar magazine includes a material bar-guiding channel system having a channel opening system. Further, the channel system of the material bar magazine has a first, outer guide channel and a second, inner guide channel mounted inside the first guide channel such that it can move relative thereto along the longitudinal direction, the second, inner guide channel couplable or coupled to the headstock of the automatic lathe so that it synchronously moves the second, inner guide channel as the headstock moves along a longitudinal axis of the material bar magazine, relative to the first guide channel.

Tool holding device (1) for a turning machine, the tool holding device comprising a housing (2) and a first oscillation mechanism (5), the first oscillation mechanism (5) comprising: a tool holder (12) with an oscillator bearing (26) for holding a tool (28); an elastic element (4) between the tool holder (12) and the housing (2); a pulse spindle (10) mounted in the housing (2) and abutting the oscillator bearing (26) with a lateral surface (21), which is substantially cylindrical and interrupted by at least one irregularity (22). The at least one elastic element (4) is arranged for pushing the tool holder (12) towards the lateral surface (21) of the pulse spindle (10), so that a rotation of the pulse spindle (10) generates an oscillation in the tool holder (12) due to the irregularity (22) in the lateral surface (21) of the pulse spindle (10).
