In order to improve a lathe includes a machine frame, a workpiece spindle unit arranged on the machine frame and having a workpiece spindle housing and a workpiece spindle rotatingly drivable about a workpiece spindle axis in the workpiece spindle housing. A supporting unit which is arranged on the machine frame and in which a workpiece receptacle rotatable about the workpiece spindle axis can be supported on the machine frame radially to the workpiece spindle axis, in such a manner that rotary machining operations other than longitudinal turning are possible in a simple manner. It is suggested that the supporting unit have a bearing member receptacle, in which a guide bushing for longitudinal turning can be supported in the area of its workpiece receptacle in a longitudinal turning version of the lathe and the workpiece spindle unit can be supported in the area of its workpiece receptacle radially to the workpiece spindle axis in a short turning version of the lathe.

Lathe

A lathe is provided that can produce complex shapes. The lathe includes a turret movement system with a B axis, which can be activated by a control. The turret axis may be designed as an H axis, which extends in a place at right angles to the B axis and can be activated by the control.

Machine tool

In order to improve a machine tool comprising a first spindle for accommodating a workpiece and a first carrier for machining units movable along an X axis, which can be moved relative to one another along a Z axis, a second carrier which is movable along an X axis and with which machining units can be moved into or out of a functional position associated with the first spindle in a transverse direction extending transversely to the X axis and transversely to the Z axis, as well as an additional carrier for machining units in such a manner that it offers optimum possibilities for the machining of a front side of a workpiece and a rear side of a workpiece, it is suggested that the second carrier bear a second spindle, that as a result of movement of the second carrier the second spindle be movable in the direction of the Z axis and the transverse direction between a workpiece takeover position and at least one workpiece machining position and that the additional machining units be arranged in a spatial area, in which machining of a rear side of a workpiece can be carried out with the second spindle located in the workpiece machining position.

A slide system for machine tools is provided, comprising a base member, at least one guide rail held on the base member and extending in a longitudinal direction, and a slide on the guide rail with at least one guide carriage. The guide rail has a guiding area and a base area. One of the base area or the base member has a receiving means extending transversely to the longitudinal direction of the guide rail and the other of the base area or the base member has an insert member insertable into the receiving means in a direction transverse to the longitudinal direction of the guide rail. A clamping element is provided for clamping the insert member in the receiving means. The insert member is fixed in a form-locking manner by the receiving means and the clamping element in all directions extending transversely to the longitudinal direction.

Slide system

In order to improve a machine tool comprising a tool carrier with a tool carrier head which is mounted for rotation about an axis and has a support member with a plurality of tool receiving means, into which drivable tool units can be inserted such that gear wheels for driving all the tool units insertable into the tool receiving means are arranged and can be moved in an interior of the support member on an orbital path extending around the axis, in such a manner that some of the tool units can be driven selectively, it is suggested that a drive wheel be rotatable about a drive axis which is arranged non-coaxially in relation to the axis, that teeth of the drive wheel move on a flight path which extends such that in a drive section of the orbital path the distances between this and the flight path have the lowest values and are greater in all the other sections of the orbital path and that the teeth be in drive engagement with a gear wheel located in the drive section and extend without contact in relation to each gear wheel located outside the drive section.

The present invention provides a lathe, comprising a machine frame, a first working spindle with a first workpiece receiving means, at least one first tool slide with a tool carrier, a second working spindle with a second workpiece receiving means which faces the first workpiece receiving means, and at least one second tool slide with a tool carrier, The machine frame has an elongated machine base member, having a first support section and a second support section arranged to follow the first support section. Each support section has a base side, a spindle support side located opposite this and two slide support sides located opposite one another and between the base side and the spindle support side. The first working spindle is arranged on the spindle support side of the first support section and the second working spindle is arranged on the spindle support side of the second support section.
