Abstract: A clamp device includes: a tool spindle including a protrusion; an additive-manufacturing head having a recess into which the protrusion is inserted in a first direction, the additive-manufacturing head being detachably coupled to the tool spindle; and a clamp mechanism portion that clamps mutually the recess and the protrusion inserted into the recess. The additive-manufacturing head includes a pin member. A pin insertion hole into which the pin member is inserted in a second direction intersecting the first direction is made in the tool spindle.

Abstract: A processing machine includes a splash guard that defines and forms a processing area, a tool spindle that is movable in a Z-axis direction and a Y-axis direction inside the processing area, an additive-manufacturing head connected to the tool spindle, and a line body that extends from the additive-manufacturing head, is drawn from an inside of the processing area to an outside, and supplies material powder and a laser beam to the additive-manufacturing head. A maximum movement amount of the tool spindle in the Y-axis direction is shorter than a maximum movement amount of the tool spindle in the Z-axis direction. A drawing direction of the line body from the inside to the outside of the processing area is a direction intersecting the Z-axis direction in top view.

Abstract: A processing machine includes a splash guard, a tool spindle that is provided inside a processing area and holds a tool, and an automatic tool changer that is movable between an internal-side tool changing position inside the processing area and a standby position outside the processing area and changes the tool held by the tool spindle at the internal-side tool changing position. The splash guard includes a cover body that is coupled to the automatic tool changer, defines and forms the processing area when the automatic tool changer is positioned at the standby position, and enters the processing area when the automatic tool changer moves from the standby position to the internal-side tool changing position.

Abstract: A processing machine includes: an external cover that forms an appearance of the processing machine and defines and forms an internal space; and a safety belt connection portion that is disposed in the internal space and to which a safety belt is connectable. The external cover includes an openable lid. The safety belt connection portion is exposed to an outside of the internal space through an opening that is generated in the external cover when the lid is in an open state.

Abstract: A processing machine performs additive manufacturing processing for a workpiece with a molten material. Processing machine includes a first cover having a first wall and a second wall that face each other in a horizontal 5 direction and forming a processing area between first wall and second wall. First wall is provided with a first opening allowing air to flow into processing area. Processing machine further includes an induction flow generator that generates an air flow flowing from below to upward along second wall. First cover is provided with a second opening allowing the air to 10 flow out of processing area.

Abstract: A machine tool capable of eliminating a laborious attachment/detachment work of a cover member is provided. The machine tool includes a door device 5 having a first door 6 to cover a machining-area opening 3e when machining a workpiece and a second door 7 to cover the machining-area opening 3e when not machining the workpiece and formed to be visible an inside thereof, in which the first door 6 and the second door 7 are arranged in a movable manner between a position-in-use covering the machining-area opening 3e and a position when opened opening the machining-area opening 3e.
