The invention relates to a machine tool including a main spindle, a machine frame, a first tool changing system for tools having a first diameter, a second tool changing system for tools having a second diameter, wherein a minimum second diameter of the tools of the second tool changing system is larger than a maximum first diameter of the tools of the first tool changing system, and wherein the second tool changing system is integrated into the machine frame.

An apparatus for provisioning, in particular automatically, a complete tool having a toolholder and a tool, in particular a drilling and/or milling tool. The apparatus has a spindle that can be driven in rotation by a driving device. The spindle has a holding device for holding a toolholder. A measuring device, in particular an optical measuring device, measures a complete tool, held on the spindle. A heating device in the region of the spindle heats a shrink-fit chuck of the toolholder held on the spindle. A cooling device, in particular a cooling device associated with the spindle, enables the spindle and/or the complete tool held on the spindle, to be cooled.

A loading device for a loading of an installation, in particular a multi-clamping and measuring and/or presetting station for tools and/or tool holders, and/or a machine tool, in particular includes at least one handling robot, having at least tool holders and/or tool assemblies, having a rollable undercarriage unit and having a storage unit, arranged on the rollable undercarriage unit, for a storage of the tool holders and/or of the tool assemblies,

wherein the storage unit has at least one holding device at least for an oblique-positioned holding of the tool holders and/or of the tool assemblies relative to a put-up direction of the storage unit.

A machine tool is disclosed. The machine tool includes a robot which is compact and which enables easy use of different end effectors for respective purposes. An internal robot includes a plurality of joints that are composed of a base joint and parallel joints, and a plurality of links. The distal end is split into two or more branches, each having a tool changer. An end effector is detachably attachable to each of the tool changers. Rotation of the base joint causes a change between a first tool-following position and a second tool-following position, so that different end effectors are used for respective purposes by using an end effector attached to a tool changer in the first tool-following position and using an end effector attached to another tool changer in the second tool-following position.

The invention relates to a machine tool, in particular a milling machine for dental purposes, with a workpiece magazine for receiving workpieces, optionally with the aid of a housing. The workpiece magazine (22) is also moveably mounted with respect to the machine tool (10) and has a fitting position (30) for fitting a new workpiece (18) in the magazine (22). The machine tool also has a housing (40), in particular a partial housing, for each workpiece (18), the housing at least partially receiving the workpiece (18), and/or has a lifting platform (32), which is arranged adjacent to the fitting position (30) and on which the housing (40) together with the workpiece (18) can be received and displaced. The invention also relates to a system comprising a machine tool and a workpiece.
