A tool magazine includes a magazine arm and a gripper plate. The magazine arm has a tool pot to hold a tool. The magazine arm is pivotable around a pivotal axis such that the tool pot pivots around the pivotal axis. The gripper plate has at least one gripper to hold the tool at a holding position on a circular arc track along which the tool moves when the magazine arm pivots. The at least one gripper is open in a tangent direction of the circular arc track at the holding position.

A system for changing and inserting or placing tools on a machine tool, including: a tool changer with a manipulator which is configured to remove a tool to be introduced from a tool magazine of the machine tool at a removal position and to transfer it to a work spindle of the machine tool at a tool change position in an automatic tool changing operation, and a tool diameter measuring apparatus, which is configured to determine a tool diameter or a tool radius of the tool to be introduced that has been removed from the tool magazine of the machine tool by the manipulator.

The present disclosure relates to a tool magazine of a machine tool such as a moving column-type machining center, in which a magazine unit is installed on a saddle, a tool accommodated in a gripper part of the magazine unit is loaded or unloaded in a direction perpendicular to a tool axis, and a gripping part of a change arm directly grips a flange portion of the tool at the time of changing the tools by means of a tool changing part movably installed on the saddle and a tool changing part transfer part configured to move the tool changing part independently of a column, thereby reducing tool change time, improving productivity, minimizing a collision or mechanical interference, and improving stability and reliability in the medium-sized or large-sized machine tool having a length in a width direction.

A tool holding part holds two boring bars in a manner in which axes of the boring bars are parallel to a spindle axis. A tool change mechanism has a circular arc movement mechanism in which the boring bar moves from a tool holding position to a tool change position by at least a circular arc movement on a plane surface including an axis of the spindle in the tool change position and an axis of the boring bar positioned in the tool holding part.

A blade mounting and dismounting jig is provided for mounting a blade on and dismounting a blade from a flange of a cutting apparatus which includes a boss, a blade mount for mounting the blade fitted thereover, the flange having an annular end face for supporting the blade thereon and being fixed to a distal end of a spindle, and a holder that cooperates with the flange in gripping and securing the blade in position. The blade mounting and dismounting jig includes a cylindrical jig body, a grip coupled to the jig body and having a diameter larger than the jig body, a plurality of first air ejection ports defined in a distal end portion of the jig body, a plurality of second air ejection ports defined in the jig body at a juncture between the jig body and the grip.

A system is provided for changing and inserting tools into or presenting tools at a machine tool. The system includes at least n rotatable tool magazines for receiving a plurality of tools, where n2, which are arranged in tandem in the direction of a rotational axis. At least one of the n tool magazines can be driven independently of the other tool magazines to perform a rotational movement about the rotational axis. The system further includes a manipulator for removing the tools from the magazine. The tools are held in tool mounts along the circumference of the n tool magazines such that the longitudinal axes of the tools in each case of one of the n tool magazines are located in one plane and project from the circumference of the tool magazine, and the tools can be moved along the circumference of the respective tool magazine.

A method, non-transitory computer-readable storage medium, and tool changing system for changing tools on a machine. The tool changing system includes a tool magazine, a tool transporter, and an automatic tool changer (ATC). The ATC includes a tool holder and a tool changer. The tool magazine is configured to store at least one tool received at the tool loading station. The tool transporter is configured to transport a tool from the tool loading station or the tool magazine to a tool transfer position of the ATC, and to hold the tool at the tool transfer position during an automatic tool change process. The tool holder is configured to hold the tool at the tool transfer position during the automatic tool change process when the tool transporter is not positioned at the tool transfer position. The tool changer is configured to provide the tool at the tool transfer position to a tool change position of a machine during the automatic tool change process.

The present disclosure relates to a machine tool, such as a moving column-type machining center, and a method of operating the same, which are capable of shortening tool change time, improving productivity, minimizing a collision or mechanical interference, and increasing stability and reliability in a medium-sized or large-sized machine tool having a long length in a width direction by means of a magazine installed on a saddle, a tool changing unit movably installed on the saddle, and a tool changing unit transfer part configured to move the tool changing unit independently of a column.

The present invention relates to a machine tool 100 for machining a workpiece 12 by means of a tool 22, which comprises a clamping means 11 for clamping the workpiece 12 and a support means 21 for receiving the tool 22, wherein the clamping means 11 is mounted on a spindle head of a clamping means-carrying work spindle 10 and the support means 21 is mounted on a spindle head of a support means-carrying work spindle 20, and the machine tool 100 is designed to position the two work spindles 10, 20 by means of numerically controllable axes in relation to one another in such a way that the workpiece 12, which is clamped in the clamping means 11, can be processed by the tool 22, which is received in the support means 21.

A tool changer includes a tool magazine, a support shaft disposed to have a center axis parallel to an axis of a tool spindle, a drive mechanism for rotating the support shaft about the center axis and moving the support shaft in the axial direction, three tool change arms fixed to the support shaft and each having a tool holding unit, a tool transfer mechanism for transferring a tool pot from the tool magazine to a standby position, and a provisional placing pot disposed at a provisional placing position. The tool changer starts a tool change operation in a state where a tool to be attached to the tool spindle, a tool to be used next, and a tool to be used after the next tool are held by the tool holding units of the tool change arms.
