The present invention relates to a tool carrierfor a machine tool, in particular a lathe, having a rotary shaft drive for a numerically controllable rotary shaft B for rotating the tool carrier, a first tool turret headA carrying tools, rotatably mounted around a first turret axis, and a second tool turret headB carrying tools, rotatably mounted around a second turret axis, the first tool turret headA and the second tool turret headB being positioned on opposite sides of the tool carrierwith respect to the axis of rotation of the rotary shaft B. The present invention also relates to a machine tool, in particular a lathe, having a tool carrierof this type.

Tool carrier and machine tool having a tool carrier

The present invention relates to a machine tool, in particular a lathe, having a machine frame, a first work spindle, arranged on a face of a first carrier portionof the machine frame, for receiving a first workpiece W, a second work spindle, facing the first work spindleand arranged on a face of second carrier portionof the machine frame, for receiving a second work piece W, the spindle axis of the second work spindlebeing aligned parallel to, in particular coaxial with, the spindle axis of the first work spindle, and two displaceable tool carrier slidesandon each of which a tool-carrying tool carrieroris arranged. According to the invention, a third tool carrieris provided which is displaceable between the work spindlesandtransverse to the spindle axes and which is arranged on a tool carrier face WTSof a central carrier portionpositioned between the first and the second carrier portion

Machine tool

A disclosed example tool changer for changing a tool on a spindle of a machine tool comprises a tool drum having a plurality of tool holders to hold tools. The example tool changer also includes an axle carrier on which the tool drum is rotatably supported to align the tool holders with the spindle. A first coupling portion is rotatably supported on the axle carrier. At least one first gear stage is provided via which the first coupling portion is connected to the tool drum. The first coupling portion is adapted to be coupled or uncoupled with a second coupling portion rotatably supported on a spindle stock of the machine tool and connected to the spindle of the machine tool via at least one second gear stage. The tool drum is adapted to be driven, when the first and second coupling portions are in a coupled state, by the spindle of the machine tool via the at least one second gear stage, the second and first coupling portions and the at least one first gear stage to align the tool holders.

Tool changers for changing tools on spindles of machine tools and machine tools comprising such tool changers

The present invention relates to a machine tool, in particular to a lathe, comprising a machine frame, a first work spindlewhich is arranged on a spindle carrier face of the machine frameand is to receive a first workpiece W, a second work spindlewhich faces the first work spindle, is arranged on a spindle carrier face of the machine frameand is to receive a second workpiece W, the axis of the second work spindlebeing aligned parallel, in particular coaxially to the axis of the first work spindle, and comprising two movable tool carrier slidesand, on which a respective tool-carrying tool carrierandis arranged. According to the invention, provided between the work spindlesandis a tool carrierwhich can be moved transversely to the spindle axes, is configured as a tool turret and the turret axis of which is aligned transversely to the spindle axes.

The present invention relates to a machine tool, in particular a lathe, comprising a machine framehaving a first carrier side TSand a second carrier side TS, wherein the machine frameincludes a first carrier portion, a second carrier portionand a middle carrier portionwhich is arranged between the first and second carrier portions, a first spindle carrierwhich is arranged on the first carrier side TSof the first carrier portionand which holds a first work spindle, a first spindle carrier slidewhich is arranged on the first or second carrier side of the second carrier portionand on which a second spindle carrieris arranged which holds a second work spindlefacing the first work spindle, wherein the spindle axes are aligned in parallel, in particular coaxially, and wherein the second spindle carriercan be moved in direction W parallel to the spindle axes, and a second tool carrier slidewhich is arranged on the first carrier side TSof the middle portionand on which a tool carrierfor tools is arranged, wherein the second tool carrier slideis arranged on the first carrier side TSbetween the first spindle carrierand the second spindle carrier
