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.

The invention belongs to the technical field of metal flame cutting processing and provides an oxyhydrogen flame numerical control punching and cutting process. The oxyhydrogen flame numerical control punching and cutting process is characterized in that oxyhydrogen is adopted as cutting gas of a numerical control flame machine tool, the oxyhydrogen is delivered to a cutting torch (6) of the numerical control flame machine tool through a busbar (5), the pressure of the cutting gas is controlled to be in a range from 0.1MPa to 1.6MPa in a numerical control manner, and is gradually increased from low to high. The oxyhydrogen flame numerical control punching and cutting process adopts the oxyhydrogen and a gradually pressurizing mode to perform metal cutting, and solves the problem of serious pollution and potential safety hazards of the traditional process.

A method for preparing a large-area super-thin stone material by use of small circular saw blade includes such steps as cutting on the big stone slab according to the sizes of needed small stone slabs to form multiple ditches, fixing the big stone slab to the bench of a horizontal cutting machine, sucking the first needed small stone strip by a sucking unit, using small circular saw blade to saw the big stone slob for separating the first small stone strip from the big one, repeating said steps until all small stone strips are separated to obtain a large-area super-thin stone material and several small super-thin stone strips. Said horizontal cutting machine is also disclosed.

The invention discloses a diamond wire saw and a manufacturing method thereof. The diamond wire saw comprises a bending-resistant flexible multi-strand rope, wherein the flexible multi-strand rope has the diameter of 0.5 to 2.0mm, and is fixed with at least two diamond braze-welding layers with the thickness of 0.1 to 2.0mm that are spaced apart from each other. 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.
