The present disclosure relates to an automatic tool changer for a machine tool which can change a tool mounted on a tool post by moving both of a magazine and a tool post to be concentric in order to change a tool in a horizontal type machine tool such as a lathe or a horizontal type turning center; a method of controlling the automatic tool changer and a machine tool including the automatic tool changer.

A machining apparatus includes: a shuttle unit (3) that holds a differential case (10) and rotates the differential case (10); a pair of opposed right and left machining units (4); and a tool support (6) that supports a tool (40) for machining the differential case (10), in which the pair of right and left machining units (4) each include a slide mechanism dedicated for uniaxial sliding in right and left directions, the shuttle unit (3) is movable in up and down directions and front and back directions, a tool attached to each of the pair of right and left machining units (4) enables machining an end portion of an inner surface of the differential case (10) and a flange hole of the differential case (10), the end portion surrounding a through hole, and a cutting edge of the tool (40) supported by the tool support (6) enables spherically cutting the inner surface of the differential case (10) held and rotated by the shuttle unit (3).

Provided is an apparatus for detecting a failure in holding a tool of a machine tool that includes, in each of a plurality of tool holding mechanisms in a tool magazine, a locking member provided to have different self-displacement positions for a case where a tool is held at a proper held position between tool gripping portions of a pair of holding arms and a case where the tool is held with deviation from the proper held position, and that detects a holding failure state of the tool in the tool holding mechanism by detecting the position of a detection target portion that moves integrally with the locking member with a predetermined detector provided in the machine tool. The apparatus makes it possible to effectively prevent a risk of a breakdown of and damage to the machine tool.

The present disclosure relates to a tool magazine for a machine tool, and more particularly, to a tool magazine for a machine tool, wherein tool receiving units of a tool magazine are provided in multiple stages in a vertical turning center, such that a spindle head may easily change internal diameter machining tools and external diameter machining tools while moving in a horizontal direction and a vertical direction.

The application describes a machine tool adapted and arranged to carry out removal and addition of material on a work piece located in a work station, the machine having a first head arranged to remove material from the work piece and at least a second head arranged to process the work piece, each of the first and second heads being arranged to be moveable in at least two axes and preferably in 3, 4 or 5 axes and wherein the machine is arranged to control an environment of the work station. The work station is at least partially sealable. The machine has a clean side and a dirty side. Novel processing heads particularly adapted for use in the new machine tool are disclosed. These may also be retrofitted to CNC machines. The novel heads include heads adapted to carry out two processes simultaneously. Heads adapted to carry out heat and pressure treatment are also disclosed. Use of the processing heads to carry out analysis in manufacturing steps is disclosed as is the provision and use of heads that can carry out analysis as well as processing.

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.

On an inner peripheral surface defining a through hole of a first rotator, provided is a positioning member for bringing the center axis of a contact tip, housed in the through hole, into alignment with a rotational axis, or making the former axis proximate to the latter axis, by coming into contact with an outer peripheral surface of the contact tip.

A machine tool has a clamping device for clamping in workpieces to be machined, a work spindle which is movable relative to the clamping device, a tool magazine wherein tools for machining the workpieces are held available, the tools being selectively clamped into the work spindle, and a spindle gripper to be selectively clamped into the work spindle and being self-holding in its gripping position, said spindle gripper being held available in the tool magazine and being movable between a transfer position to the work spindle and an unloading station in which the spindle gripper releases a work piece remnant received from the clamping device.
