Автор: Kazuya Maekawa, Keisuke Tominaga
Принадлежит: Mitsuboshi Diamond Industrial Co Ltd

A cutter with which a diagonal crack can be created without fail deeply within a brittle material substrate is provided. The cutter has such a form that two cones or truncated cones are joined through the same bottom so as to share the same rotational axis, and the circumference of the above described bottom is used as the blade edge ridge line. In addition, grooves that incline at a predetermined angle relative to the direction of the rotational axis are created around this blade edge ridge line at predetermined intervals. Furthermore, the angles between the sides of the above described two cones or truncated cones and the above described bottom are different from each other.

Front feet are provided at a lower part of a cutting-machine main body via a foot holder. Furthermore, a slider positioned on a front side relative to the front feet is provided at the lower part. When a workpiece to be cut is to be cut by a blade, the cutting-machine main body is tilted so as to let the blade go down. When the cutting-machine main body is tilted, a state where the front feet are in contact with the workpiece is switched to a state where the slider is in contact with the workpiece. Then, by moving the cutting-machine main body forward while sliding the slider on the workpiece, the workpiece is cut by the blade. In the cutting operation, the front feet can get away from the workpiece. Therefore, damage of the front feet can be prevented, and the running cost can be suppressed.

The present invention relates to a blade for a cutting tool of a ceramic cutting machine that improves the stability and quality of the cut made on ceramic tiles by means of said cutting machines, due to its specific geometric features. Said cutting tools of ceramic cutting machines are commonly known as “scoring wheels” and the blade they comprise is commonly known as “scoring blade”.The invention is applicable to the field of the metal tool manufacturing industry and the handling ceramic material industry.Current ceramic cutting machines that are manually operated typically comprise a bench where the tile or ceramic piece to be cut is placed, a positioning element of said tile in the bench, and a sliding lever that slides on rails, having a tool carrier element in which a cutting tool (or “scoring wheel”) is inserted, which is in turn formed by a handle and a disc-shaped blade (or “scoring blade”). By means of the pressure exerted by the lever, a certain pressure is exerted by the scoring wheel on the tile to be cut. While exerting said pressure, and by advancing the lever with its tool carrier along the rails, a cut is progressively made on the tile.In ...

A system for processing diamonds claim 1 , comprising:a helium-silver ion laser configured to emit a beam at a wavelength of 224 nm;and a gem holder configured to hold a diamond in a path of said beam. The present invention relates generally to a method and device for cutting, shaping and polishing diamonds by a laser beam of wavelength identical to the peak absorption wavelength of diamond, or slightly shorter, with minimal damage to the specimen thus processed, due to the ability to use minimal laser power.Laser processing of a large variety of materials is replacing conventional mechanical processes, due to the high accuracy, speed and flexibility provided by laser cutting, sawing and shaping and polishing machines.Laser processing is based on the ability to focus the laser light beam to an extremely small focal spot, thus concentrating the beam energy to an extremely high power density, which can ablate very accurately a very small region of material, thus making it possible to produce very narrow and accurate cuts and slits in nearly every material.This, however, is based on the existence of an interaction mechanism between the laser beam and the processed material.

A wafer is produced from a compound single crystal ingot having end surface. A separation plane is formed by setting the focal point of a laser beam inside the ingot at a predetermined depth from the end surface. The depth corresponds to the thickness of the wafer to be produced. The laser beam is applied to the end surface to form a modified layer parallel to the end surface and cracks extending from the modified layer, thus forming the separation plane. The ingot has first atoms having a larger atomic weight and second atoms having a smaller atomic weight, and the end surface of the ingot is set as a polar plane where the second atoms are arranged in forming the separation plane. After producing the wafer from the ingot, the first end surface is ground to be flattened. 1. A wafer producing method for producing a wafer from a compound single crystal ingot having a first end surface and a second end surface opposite to the first end surface , the wafer producing method comprising:a separation plane forming step of holding the second end surface of the compound single crystal ingot on a chuck table, next setting a focal point of a laser beam having a transmission wavelength to the ingot inside the ingot at a predetermined depth from the first end surface of the ingot, which depth corresponds to a thickness of the wafer to be produced, and next applying the laser beam to the first end surface as relatively moving the focal point and the ingot to thereby form a modified layer parallel to the first end surface and cracks extending from the modified layer, thus forming a separation plane containing the modified layer and the cracks;a wafer producing step of separating a plate-shaped member having a thickness corresponding to the thickness of the wafer from the ingot at the separation plane after performing the separation plane forming step, thus producing the wafer from the ingot; anda flattening step of grinding the first end surface of the ingot after performing the ...
