The processing of some semiconductor or insulator hard and brittle materials such as monocrystalline silicon, ceramics, sapphire and the like is always a difficult problem in mechanical manufacturing, due to the characteristics of the materials, the high hardness makes a general cutter difficult to cut into a workpiece, and the high brittleness makes the materials extremely easy to break in the processing process, so that the processing requirements are difficult to meet, and meanwhile, due to the poor conductivity of the materials, the processing is difficult to be carried out by using an electric spark machine tool.
In recent years, a type of machine tool for hard and brittle materials, i.e., a wire saw machine, has appeared. The wire saw machine tool according to the type of the saw wire can be divided into a fixed saw wire saw machine tool and a free abrasive wire saw machine tool; the wire saw machine tools according to the cutting mode can be divided into a horizontal push cutting wire saw machine tool, a swing cutting wire saw machine tool and a rotary point cutting wire saw machine tool; the cutting machine can be divided into a single wire saw machine tool and a multi-wire saw machine tool according to the number of the saw wires participating in cutting; the sealing of the saw wire can be divided into an open wire saw machine and a ring wire saw machine, fig. 1 is a schematic view of a fixed abrasive wire saw (in which a saw wire matrix 1 and abrasive grains 2 arranged on the saw wire matrix are shown), fig. 2 is a schematic view of a free abrasive wire saw (in which the saw wire matrix 1 and the abrasive grains 2 and an abrasive nozzle 3 are shown), fig. 3 is a schematic view of a push-pull cutting wire saw (in which a saw wire 4 and a workpiece 5 are shown), fig. 4 is a schematic view of an oscillating cutting wire saw (in which a saw wire 4 and a workpiece 5 are shown), fig. 5 is a schematic view of a rotating point cutting wire saw (in which a saw wire 4 and a workpiece 5 are shown, arrows indicate the direction of rotation of the workpiece), fig. 6 is a schematic view of a single wire saw, fig. 7 is a schematic view of a multi-wire saw, fig. 8 is a schematic view of a ring (closed) wire saw machine, and fig. 9 is a schematic view of an open wire saw machine, in which a wire storage tube 6, a wire storage tube, a tube, and a tube are shown in the two tube, A wire releasing and storing cylinder 7.
When the saw wire of the existing fixed abrasive wire saw machine tool is used for cutting, only the lower half part of the saw wire participates in cutting processing, the number of abrasive particles participating in cutting processing in unit time is small, so that the cutting efficiency is low, and after the saw wire is worn for a period of time, the saw wire needs to be replaced, so that only half of the abrasive particles of the saw wire participate in cutting processing each time, and the utilization rate of the saw wire is low.

Referring to fig. 23, the cooling unit 70 includes a cooling liquid tank 700, a nozzle 701, and a cooling liquid recovery tank 702, the cooling liquid tank is fixedly mounted on the through hole of the bed body through bolts and nuts, the cooling liquid is contained in the cooling liquid tank, when cutting processing is performed, the cooling liquid is sprayed to the cutting position of the saw wire through the nozzle to realize cooling and flows to the cooling liquid recovery tank for recovery, and the cooling liquid recovery tank is placed on the concave table.
In the invention, the torque of the motor is transmitted into the saw wire circumferential rotation motion unit through the synchronous unit and the synchronous belt, the synchronous belt drives the synchronous belt pulley to rotate, and the saw wire, the centering guide wheel and the cutting shaft rotate together along with the synchronous belt pulley. Because the two cutting shafts can synchronously rotate through the synchronizing unit, the saw wire cannot be twisted and integrally rotates.
The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any way. It will be understood by those skilled in the art that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
