Method and device for cutting transparent material by using ultra-short pulse laser

The invention provides a method for cutting a transparent material by using ultra-short pulse laser. The ultra-short pulse laser output by an ultra-short pulse laser generating device is condensed by a condensation device so as to form a bunching laser beam; the bunching laser beam enters from the surface of the transparent material to be machined, so that the center refractive index at a laser application point is increased to form a waveguide structure along a laser emitting direction; the laser is transmitted to the inside of the transparent material along the waveguide structure, and continuously generates a waveguide structure along the laser emitting direction in a transmission process until the entire waveguide structure and the laser penetrate through the transparent material; and therefore, the laser moves in a direction which is vertical to the surface of the transparent material at uniform speed, so that a waveguide plane is formed in the transparent material. The invention further provides a device for cutting the transparent material by using the ultra-short pulse laser. The method and the device for cutting the transparent material by using the ultra-short pulse laser provided by the invention have the advantages of fast cutting speed, small cutting seam, no material consumption and no powder pollution. When the machined material bears a suitable external force, the material is cracked only along a stress fault surface; the broken surface nearly has no conical degree; and the roughness is good.

Diamond bead string and manufacturing method thereof as well as rope saw without base body supporting layer

The invention discloses a diamond bead string and a manufacturing method thereof as well as a diamond bead string rope saw without a base body supporting layer. The manufacturing method of the diamond bead string comprises the following steps of: uniformly mixing metal powder, diamond and an organic binding agent; manufacturing a rough blank of the diamond bead string through a pre-hot-pressing modeling or metal injection molding (MIM) process; and obtaining a finished product of the diamond bead string by placing the rough blank in a high-temperature furnace for one-step sintering modeling process after degreasing. The manufacturing method of the diamond bead string provided by the invention can be used for sintering the rough blank in one step to form an entire cylindrical bead string without a bead string base body layer; the external diameter of the bead string becomes smaller, so that the bead string can be directly stringed into a steel wire rope to obtain a diamond rope saw with a smaller external diameter; the bead string is molded through one step without a last-stage permeation process, so that the production cost of the diamond bead string is greatly reduced. Furthermore, the diameter of the diamond rope saw is smaller, and a cutting seam of a stone material to be cut is smaller, so that the yield of rough stone block is improved. The manufacturing method of the diamond bead string is beneficial to large-range popularization and utilization of the diamond rope saw.

Diamond wire saw and manufacturing method thereof

The invention discloses a diamond wire saw and a preparation method thereof. The diamond wire saw comprises a bending-resistant flexible multi-strand rope. The preparation method comprises the following steps: a, removing oil from the surface of the flexible multi-strand rope and coating high-temperature resistant inorganic glue onto the flexible multi-strand rope at intervals, so as to form an isolated coating layer after the glue is cured; b, adding metal soldering materials into the organic glue to prepare a pastry mixture; c, coating or impregnating the pastry metal soldering materials onto the spaced parts of the flexible multi-strand rope, and then spreading diamond abrasive particles onto the rope; spraying or cold-pressing a layer of metal soldering materials onto the surface of the rope after the organic glue is cured; d, putting the obtained flexible multi-strand rope into a vacuum brazing furnace for sintering, taking the rope out of the furnace and then removing the inorganic glue; after heat treatment, coating a layer of rubber-plastic material protection layer onto the spaced parts of the flexible multi-strand rope; after the glue is cured, obtaining the diamond wire saw. The diamond wire saw can effectively prevent a braze-welding material from entering into gaps of the flexible multi-strand rope so as to solve the problem that the conventional diamond wire saw manufactured by taking the flexible multi-strand rope as a centre line is too inflexible and is entirely unusable.
