The invention discloses an annular superhard abrasive wire and a manufacturing method thereof. The base body of the annular superhard abrasive wire is a wire rope, the wire rope is connected in an end-to-end mode to form an annular shape, superhard abrasive particles are uniformly consolidated on the surface of the wire rope so as to form a superhard abrasive layer, the superhard abrasive layer is a single particle thickness layer, the wire rope comprises a core and compound yarns spirally wound on the core, the initial end and the tail end of the core are connected to form an annular shape, the length of the compound yarns wound on the core meets the requirement that the compound yarns can be wound on the core for six turns, after the compound yarns are wound on the core for six turns, the compound yarns are connected in an end-to-end mode, and joints of the compound yarns are disposed at one side of a core connecting point. The annular superhard abrasive wire is narrow in joint cutting, high in efficiency and good in cutting surface quality, and also has higher anti-fatigue strength.

The invention discloses an ultrafast femtosecond laser cutting machine. The ultrafast femtosecond laser cutting machine comprises a bearing platform, wherein multiple support rods are arranged at the lower end of the bearing platform at equal intervals; damping devices are arranged at the lower ends of the support rods, and a connecting rod is connected between every two adjacent support rods; a bearing plate is arranged at the upper end of the bearing platform, first electric sliding rails are arranged on two sides of the bearing platform, second sliders are mounted on the first electric sliding rails, mounting blocks are arranged at the upper ends of the second sliders, first vertical plates are fixed at the upper ends of the mounting blocks, and a mounting plate is arranged between the two first vertical plates. The ultrafast femtosecond laser cutting machine had the remarkable advantages of being high in machining speeds, high in accuracy, simple in parameter setting and the like through femtosecond laser cutting; a product obtained through femtosecond laser cutting does not have the problems of microcracks, breaking or fragments in the aspect of appearance quality; no contamination or edge breakage are caused, and the edge breakage resistance is very high; washing and polishing are not required, the manufacturing cost is reduced and the ultrafast femtosecond laser cutting machine is suitable for popularization.

The invention discloses a portable wire cutting saw and relates to the technical field of wire cutting. The wire cutting saw comprises a saw body, universal spray pipes, a wire electrode, a front wire winding mechanism, a front wire guiding mechanism, a rear wire guiding mechanism and a rear wire winding mechanism, wherein the saw body is fixedly connected with a handle, the front wire guiding mechanism is arranged at the end of the saw body, which is far from the handle, and the rear wire guiding mechanism is arranged at the end of the saw body, which is close to the handle; the front wire winding mechanism is located above the front wire guiding mechanism, and the rear wire winding mechanism is located above the rear wire guiding mechanism; one end of the wire electrode is wound on the front wire winding mechanism, the wire electrode sequentially passes through the front wire guiding mechanism and the rear wire guiding mechanism, and the other end of the wire electrode is wound on the rear wire winding mechanism. The using steps of the wire cutting saw comprise preparing the wire electrode, mounting the wire electrode, adjusting the tensioning force, spraying a working solution, starting wire cutting, dismounting for standby use after the cutting is finished. The wire cutting saw can realize narrow-slit cutting, cutting of workpieces with large thicknesses, good cutting surface texture and any curvilinear cutting.
