A machine tool system includes a machine tool main body for machining a workpiece supported on a table by using a tool detachably attached to a spindle, and an information processing apparatus. The machine tool main body includes a rotary tool magazine in which multiple grips each capable of holding the tool to be attached to the spindle are provided along the circumferential direction, and an image pickup device that is arranged in the tool magazine and configured to take an image of multiple members in a machining area of the machine tool main body. The information processing apparatus includes a geometric feature calculating unit configured to calculate the shapes and the arrangement state of the multiple members in the machining area, based on image data of the image taken by the image pickup device.

Provided is a tool magazine capable of automatically exchanging a tool holder between the tool magazine and a spindle. A tool magazine includes: a magazine body; an operation lever disposed to the magazine body, the operation lever reciprocable in the axial direction of the spindle with the operation sleeve in a supportable manner, the operation lever including, an operation sleeve receiving hole configured to receive the operation lever, and a hook portion disposed in the operation sleeve receiving hole to be hooked in the receiving portion, an operation lever guide configured to guide the operation lever in the axial direction of the spindle; and an operation elastic body configured to urge the operation lever toward a basal end of the spindle against an elastic force of the holder elastic body.

A cutting machine includes a holder located below a spindle to hold processing targets, and an adaptor connected to a rotation shaft to rotatably support the holder. The holder includes a first holder fixed to the adaptor and including a pin insertion hole to which a fixing pin attached to a processing target is fixed, and a second holder detachably attached to the first holder and including a pin insertion hole at a position facing the pin insertion hole. The fixing pin extends in a Y-axis direction. In the Y-axis direction, a distance between a processing target fixed to the pin insertion hole and a processing target fixed to the pin insertion hole is shorter than a length of the fixing pin.

A tool changing device for a machine tool comprises a handling unit comprising a handling robot, an interchangeable tool magazine, and a provisioning site for the tool magazine. The handling unit comprises a tool gripper for gripping tools. The tool magazine is configured as an upright disk magazine with a vertical rotation axis. The tool magazine is detachably mounted at the provisioning site on a rotary table that is rotatable to provide a desired rotational position of the tool magazine for a tool change in which a selected tool location in the tool magazine is accessible for the tool gripper of the handling unit. The handling unit is adapted to change tools between the tool magazine and a tool holder in a workspace of the machine tool. The handling unit and the tool magazine are arranged in a setup cell of the tool changing device, which is arranged to be coupled to the workspace of the machine tool via a closable setup interface. The handling robot is adapted to move the tool gripper through the setup interface into the workspace to change tools there. A manufacturing system includes a machine tool and a tool changing device.

A dental milling machine comprising a workpiece holder (2) and a changer arm (10) is characterized in that the changer arm (10) has a substantially U-shaped gripping attachment (12) and in that a tool (14) of the dental milling machine (1) has a tool fixation element (16). The tool fixation element has grooves (18) or holding projections at two mutually opposed positions which face away from each other, over which grooves or holding projections the U-shaped gripping attachment (12) of the changer arm (10) can engage, wherein parts of the U-shaped gripping attachment (12), more particularly the side flanks (12a, 12b) of the U-shaped gripping attachment (12), make contact with the grooves (18) or holding projections of the tool fixation element (16) under preload.

A tool cartridge for accommodating a processing tool is provided. The tool cartridge includes a cartridge base body, a tool holder for detachably holding the processing tool, and at least one first coupling device configured to be coupled in a form-fit and detachable manner to a second coupling device of a further tool cartridge, the second coupling device being complementary to the first coupling device.

An automatic tool changer includes a cover that partitions a machining area and a non-machining area, and an opening/closing member that opens/closes an opening of the cover by turning in synchronization with rotation of a tool changer magazine. The opening/closing member includes a plate section partitions the machining area and the non-machining area at a position of the opening of the cover. In a case where the tool changer magazine performs tool replacement with respect to a tool storage magazine, the plate section closes the opening of the cover by taking a horizontal posture. In a case where the tool changer magazine performs tool replacement with respect to a main spindle, the plate section opens the opening of the cover by changing its posture from the horizontal posture to an inclined posture or a vertical posture.

A cutting machine having a table with a working surface is disclosed. The working surface including a crossbeam above the working surface configured to be linearly positioned parallel to a first horizontal axis, a module, mounted on the crossbeam configure to be positioned parallel to a second horizontal axis, which extends perpendicularly to the first horizontal axis, a tool holder mounted in the module configured to move in a vertical axis and rotate about the vertical axis, and to accept one of a plurality of different interchangeable tools, and a control unit, wherein the tool holder has a connection device designed to supply the tool with power and a fluid, wherein the supply with the fluid is provided via a rotary joint, and wherein the power is provide via a rotary transmitter.
