A dust collection assembly for a computer numerical control (CNC) cutting machine includes an adapter configured to couple to an arm of the CNC cutting machine and a head telescopically coupled to the adapter by a plurality of nested members. The CNC cutting machine includes the arm supporting a spindle and a tool holder coupled for co-rotation with the spindle. Each of the plurality of nested members are collapsible relative to each other. The head is movable between an extended position in which the nested members are configured to surround the tool holder and a tool bit, and a retracted position in which at least some of the nested members are telescopically received in the adapter. The head defines an inlet fluidly connected to the plurality of nested members when the head is at least in the extended position. The inlet is configured to fluidly connect to a vacuum.

A machine tool has a splash guard and a guiding section. The splash guard has a first sidewall portion on which an end portion of a telescopic cover abuts, a slope portion slanting from the first sidewall portion along an expansion and contraction direction of the telescopic cover, a second sidewall portion perpendicularly extending downward from the slope portion, and a bottom portion horizontally extending from the second sidewall portion more inward than a lower end of the slope portion in the splash guard. The guiding section is disposed more inward than the lower end of the slope portion in the splash guard and configured to guide the cutting fluid falling from the slope portion, toward the bottom portion.

A sheet material bending system includes a tool changing apparatus that changes tools between a press brake and a tool stocker. The tool stocker is arranged behind the press brake. To change tools from the front and rear of the tool stocker, the front and rear of the tool stocker are opened. The tool changing apparatus has a pivot that is movable in front-rear, left-right, and up-down directions and is rotatable around an axis extending in the up-down direction. A front end of the pivot is provided with tool holding units to hold tools.

The invention relates to a machining device for the machine-assisted production and machining of dental workpieces (16), particularly of artificial teeth and/or other dental replacement parts, the at least one workpiece (16) being clamped in at least one workpiece retainer (11) which can be raised, lowered and rotatably driven, is positioned on a rotational axis (9), and, for the purpose of machining, feeds said workpiece (16) to at least one tool spindle (4, 5, 6) that is rotationally driven and has a tool (7) secured thereto, an additional tool retainer (2, 2a, 2b) with a plurality of tools (7) arranged thereupon being associated with said workpiece retainer (11, 11a, 11b) and lying opposite on one side thereof, and a workpiece changer (22, 22a, 22b) which receives the workpieces (16, 16a, 16b, 16c) to be machined, such that they can be exchanged, being arranged on the other side of said workpiece retainer (11, 11a, 11b).

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 machine tool includes a bed, a column, a rotary main spindle, a tool magazine, a tool changer, and a controller. The tool changer includes a body provided on the bed so as to be movable in a direction orthogonal to a movement direction of the column, a changing arm rotatably provided on the body, and a door provided on the body to open or close an opening formed in the body, and configured to partition an area on the column side from an area on the tool magazine side by closing the opening. The controller is configured to move the body in parallel with at least one of an operation of opening the door and an operation of closing the door.

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 machine tool, which has a tool magazine for storing multiple tools and is for machining a workpiece with a tool held on a main shaft by moving the main shaft relative to the workpiece, wherein the machine tool is provided with: multiple feed shafts for moving the tool relative to the workpiece; a tool magazine drive motor for driving the tool magazine; and a manual pulse generator, which is for sending a positive or negative command pulse to the multiple feed shafts or tool magazine drive motor, the manual pulse generator being provided with a selection switch for selecting one of the multiple feed shafts or the tool magazine drive motor as the destination to which the command pulse is to be sent.

This machine tool comprises a machining chamber in which machining of a workpiece is performed, and a tool storage chamber in which a plurality of tools are stored. The machine tool is further provided with a partition which partitions the machining chamber and tool storage chamber from one another. The machine tool is positioned on the front side of the machining chamber, and is equipped with a first sliding door that moves in the width direction, and a second sliding door that is positioned on the front side of the tool storage chamber and that moves in the width direction. The first sliding door and second sliding door are positioned in such a manner that one of the sliding doors is positioned on the front side of the other sliding door, and when one of the sliding doors is opened, said door overlaps with the other sliding door.

Machine tool including a workpiece carrier assembly including a workpiece carrier for supporting a plurality of workpieces, the workpiece carrier assembly being supported on a workpiece carrier support for horizontal movement in a first direction parallel with a horizontal Z axis, a tool carrier configured for carrying a plurality of tools corresponding to the plurality of workpieces and for machining the workpieces, the tool carrier being supported on a tool carrier support for horizontal movement in a second direction parallel to a horizontal X axis, the X axis being perpendicular to the horizontal Z axis, where the tool carrier is displaceable on the tool carrier support in the second direction between an operative position in which the tools are arranged for the contacting the workpieces and an inoperative position in which the workpieces are not contactable by the tools, where the workpiece carrier is arranged to be rotatable around an axis parallel with the X axis, and where the workpiece carrier includes a workpiece support area for supporting the workpieces and arranged substantially in parallel with the X axis.
