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.
Claims10
A processing machine capable of performing additive manufacturing and subtractive manufacturing for a workpiece, the processing machine comprising:
- a splash guard that defines and forms a processing area;
- a tool spindle that holds a rotating tool for the subtractive manufacturing for the workpiece and is movable inside the processing area in an axial direction of a first axis parallel to a horizontal plane and an axial direction of a second axis parallel to the horizontal plane and orthogonal to the first axis;
- an additive-manufacturing head that is connected to the tool spindle, discharges material powder to the workpiece, and irradiates the workpiece with a laser beam;
- a workpiece spindle that holds the workpiece and rotates the workpiece about a rotation axis parallel to the first axis;
- and
- a line body that extends from the additive-manufacturing head, is drawn from an inside to an outside of the processing area, and supplies the material powder and the laser beam to the additive-manufacturing head, the line body including an optical fiber guiding the laser beam and including a gas pipe serving as a flow path of inert gas,
- wherein
- a maximum movement amount of the tool spindle in the axial direction of the second axis is shorter than a maximum movement amount of the tool spindle in the axial direction of the first axis, and
- a drawing direction of the line body from the inside to the outside of the processing area is a direction intersecting the axial direction of the first axis in top view.
