A combined machining apparatus includes a tool holder, a first automatic exchanger capable of containing at least one laser machining head and mounting the at least one laser machining head on the tool holder, and a second automatic exchanger capable of containing at least one mechanical machining tool and mounting the at least one mechanical machining tool on the tool holder.

This tool exchange device for a machine tool uses an exchange arm to exchange tools between a processing area and a tool accommodation area which are partitioned by a partition wall provided with an opening and a shutter capable of opening and closing the opening. In the tool exchange device, an imaging device is used to capture an image of a tool in the tool accommodation area, the length of the tool is calculated from the captured image of the tool, the opening width of the shutter is determined in accordance with the length of the tool, and the shutter is opened to the determined opening width.

A universal rotating chuck system capable of accommodating multiple small-batch or one-off machining jobs, involving workpieces of different diameter and composition, comprises a rotating chuck having multiple jaws that may be adjusted positionally inward or outward towards the longitudinal centerline of the workpiece or removed entirely. The chuck is rotated by a dual-motor system driving an inner and outer shaft, where the inner shaft is selectively coupled to the outer shafts to rotate independently and adjust the jaws, or rotate alongside the outer shaft to rotate the chuck. In operation, the system is capable of conducting numerous machining operations independent of direct user intervention, including loading/unloading workpieces, loading/unloading tools, measuring tools and workpieces for quality control, and storage.

A machine tool includes: a turret configured to hold a tool through a clamp mechanism; a workpiece main spindle device configured to rotatably hold a workpiece; a switching unit configured to change a clamp state of the clamp mechanism by using rotation torque of the workpiece main spindle device; and an in-machine robot configured to move the switching unit. The clamp mechanism includes a torque input hole to which rotation torque is applied to change the clamp state. The switching unit includes an input shaft coupled with the workpiece main spindle device, an output shaft coupled with the torque input hole of the clamp mechanism and configured to output torque to the torque input hole, and a transmission mechanism configured to transfer, to the output shaft, the rotation torque of the workpiece main spindle device input through the input shaft.

A tool transfer system includes: a machine tool; a tool storage section in which a plurality of tool holders are able to be stored; a workstation for a worker to perform work for the tool holders; a transfer device for transferring a designated tool holder among a tool holder in the machine tool, a tool holder in the tool storage section, and a tool holder in the workstation, to a designated transfer destination, which is one of the machine tool, the tool storage section, and the workstation; and a controller for controlling the tool transfer system. If a tool holder to be removed from the machine tool includes a tool holder holding an unusable tool, the controller controls the transfer device so as to transfer the tool holder to be removed, from the machine tool to the workstation.

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 cutting blade supplying apparatus includes a cutting blade stocker that stocks a plurality of cutting blades; a carrying unit that carries out the cutting blade from the cutting blade stocker and carries the cutting blade to a cutting apparatus, a transferring unit that transfers the cutting blade carried by the carrying unit to a cutting blade replacing unit of the cutting apparatus, and a control unit. The cutting blade stocker includes a cutting blade case that accommodates the cutting blades each of which includes a mounting port formed in a center thereof to be mounted to a spindle and a cutting edge formed at an outer periphery of the mounting port, and a cutting blade case mounting unit on which to mount the cutting blade case.

The invention relates to a tool magazine (1) for a manipulator (4) comprising a plurality of tool holding fixtures (2) which are distributed in a preparation area (7), especially in a substantially vertical preparation plane (11). The tool magazine (1), on one side (9) of the preparation area (7), comprises a first access opening (10) facing the manipulator (4) and, on the other side (15) of the preparation area (7), a second access opening (16) facing an operator (13) and the first access opening (10) is associated with a first protective device (17) and the second access opening (16) is associated with a second protective device (18).

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.
