Abstract:
PROBLEM TO BE SOLVED: To provide a cutting processing device capable of easily positioning a processed object and a cutting nozzle, capable of uniformly and efficiently cutting the processed object in safety by jet injection corresponding to the outer shape of the processed object at all times, and surely and efficiently executing the entire processing process to an article including an ignitible hazardous substance.SOLUTION: A nozzle unit 10 includes a first nozzle moving mechanism for moving the cutting nozzle 11 on a pathway along a tangential direction of the circumference of a swiveling locus, a second nozzle moving mechanism for moving the cutting nozzle on a pathway along the direction orthogonal to the tangential direction, and a measuring device for measuring the outer shape of the processed object in association with the swiveling. A control device drives and controls the first and second nozzle moving mechanisms in swiveling for cutting on the basis of a result of the measurement of the outer shape of the processed object measured by the measuring device in swiveling for measurement in advance, to adjust an injection axis of the cutting nozzle on a position to intersect a central shaft of the processed object and to keep a constant distance to a surface of the processed object at all times.

PROBLEM TO BE SOLVED: To provide a peening tool, capable of intensively peening a specific processing area in the peripheral direction at a work surface, and capable of miniaturizing a retainer for retaining a pressing body for performing peening.SOLUTION: The peening tool 1 includes: a mandrel 10 having an operation section 13 for driving a ball 7 that is a pressing body in the diametrical direction; a supporting member 20 having a retainer 40 for movably retaining the ball 7 in the diametrical direction. The ball 7 driven by the operation section 13 performs peening for an opening edge 4a of an inner-peripheral surface 4. The supporting member 20 includes: a body 21 having first and second support sections 31, 32 that rotatably support the mandrel 10; and a rotation prevention section 36 fixed on a jig 60 to prevent rotation of the retainer 40 and the body 21 during rotation of the mandrel 10. The retainer 40 extends from the body 21 in the axial direction and retains the ball 7 at a position distant from the first and the second support sections 31, 32 in the axial direction.

PROBLEM TO BE SOLVED: To provide a water-jet cutting device and cutting method for an explosive article, for reliably holding an object rotatably around a major axis and easily cutting the object even when the shape of the object is distorted. SOLUTION: In the water-jet cutting device for the explosive article, a holding means for holding the object to be cut on a working table includes one or more cylindrical members each having a plurality of bolt members screwed into female screw through holes formed on one outer circumference at equal angular intervals and screw-fastened movably forward and backward along a radial direction, and the object to be cut is sandwiched by the distal end portions of the blots, and held in the cylindrical member. The object to be cut is rotated around a center axis of the cylindrical member together with the cylindrical member to which a clamp portion communicating to a rotating drive mechanism is fitted.

Abstract:
PROBLEM TO BE SOLVED: To provide a collision apparatus capable of achieving higher atomization performance by making the most of the impact force of a high-pressure jet. SOLUTION: The collision apparatus sprays a high-pressure jet of a slurry raw-material liquid from a single spray nozzle onto a hard plate member arranged in the chamber body through the shortest collision distance and has a means of causing a passage resistance Pd meeting the following condition to act with respect to the spraying pressure Pi of the high-pressure jet. The condition: 10 9 ×(d×V/υ) -1.35 7 ×(d×V/υ) -0.97 (wherein, d is the caliber of the spray nozzle; V is the flow rate; and υ is the kinematic viscosity of the raw material).

Abstract:
PROBLEM TO BE SOLVED: To provide a tool and a method for 3D abrasive jet processing, capable of executing 3D abrasive jet processing inexpensively and efficiently. SOLUTION: A catcher 6(b) disposed around a side wall portion of the tool body 3 is constituted by storing a spherical member 5 located higher than a lowest position of a workpiece 7 therein. Accordingly, an abrasive jet 18 can be dampened by the spherical member 5 located higher than the lowest position of the workpiece 7 in the catcher 6(b). Thus, the abrasive jet 18 can be jetted through a slit 8(b) formed corresponding to a processing locus L2 in processing a side portion of the workpiece 7 and the side portion of the workpiece 7 higher than the lowest position can be processed.
