Abstract: A chain link includes a base area, confined by four sides, and first to third link portions respectively on first to third sides. The first and second link portions respectively receive first and second connection elements for connecting the chain link to first and second adjacent chain links, and respectively and relatively define first and second rotational axes of adjacent first and second chain links. The third link portion receives a third connection element for connecting the chain link to a tool receptacle and defines a third rotational axis of a rotary motion of the tool receptacle in relation to the chain link. The first and second axes define a first plane, the first plane is parallel to the chain link base area, and the third axis lies outside the first plane. A tool magazine for a machine tool includes a link chain from chain links for the tool transport.

Abstract: A machine tool having a machine frame which has a stand and a machine sub-structure, a workpiece carrier arrangement which can be moved on linear guides, and a machining unit which is arranged on the stand. The machining unit can be moved along at least one coordinate axis and comprises an exchangeable cutting tool. The linear guides and the linear drives of the workpiece carrier arrangement are covered by longitudinally continuous, stationary cover elements and are thus protected against chip deposits.

Abstract: A tool chain magazine, in particular for program-controlled milling machines and machining centers, comprising a stationary supporting structure to which linear guiding devices, chain wheels, and a drive assembly as a rotary drive for at least one of the chain wheels are mounted. The tool chain comprises an endless magazine chain consisting of a series of chain links connected in an articulate manner to one another, wherein supporting and guiding elements are provided on each chain link, and each chain link has a respective socket as a holder for a tool taper. The base bodies of the chain links of the magazine chain are formed by the tool stations centrally disposed therein, and the front and rear connecting joints of the chain links are arranged in the longitudinal center axis of the magazine chain.

Abstract: A tool changer for machine tools, the tool changer having at least one rotatable tool gripper, a supporting column for the tool gripper which can be lifted and lowered and rotated about a rotational axis, a mechanical cam gear for generating the lifting and rotating movements of the tool gripper, all driven by a drive motor connected to a cam barrel and intermediate gearing. The cam barrel has a tappet for the rotational drive of the tool gripper on its upper front and a cam curve or groove on its peripheral surface for the lifting movement of the tool gripper. The tappet drives a Maltese wheel supported on a shaft parallel to the rotational axis of the tool gripper. The Maltese wheel, the cam barrel, and the supporting column of the tool gripper are successively supported in a manner parallel to the axis.
