The first cutting roller 4, the second cutting roller 5 and the 6 winding rollers 6 are all arranged on the front panel of the rack 1. The first cutting roller 4, the second cutting roller 5 and the plurality of winding rollers 6 comprise the same rollers, and V-shaped grooves are formed in the rollers; the annular diamond wire 11 is an annular steel wire which is flexibly plated with diamond particles and has the diameter of 0.1-0.6 mm, and the annular diamond wire 11 surrounds the first cutting roller 4, the second cutting roller 5 and the plurality of winding rollers 6 and is arranged in the V-shaped groove.
The groove type of the V-shaped groove of each roller is the same, and the starting groove of the V-shaped groove is positioned on the same plane. The annular diamond wires 11 in the V-shaped grooves all rotate at high speed in the same plane, and the annular diamond wires 11 only work in the grooves.
The first cutting roller 4 and the second cutting roller 5 provide advancing power for the annular diamond wires 11, and the same-direction rotating power of the first cutting roller 4 and the second cutting roller 5 rotates to drive the winding rollers 6 to rotate in a driven mode, so that the annular diamond wires 11 circularly rotate in the anticlockwise direction.
In the present embodiment, the first cutting roller 4 and the second cutting roller 5 are driven by a high-speed motor respectively.
In order to ensure the synchronization at high speed, a first cutting roller 4 is set as a driving wheel, and a second cutting roller 5 is set as a following wheel; after the first cutting roller 4 is driven by a given high-speed rotation speed value, the second cutting roller 5 acquires feedback of the high-speed rotation speed value and corrects the rotating speed of the first cutting roller 4, so that the high-speed synchronism of the two rollers is ensured, and the requirement of the linear speed of 50-100 m/s or more is met.
The swing device 2 is arranged on a front panel of the frame 1, the swing device 2 comprises a vertically arranged swing fixed disc 3, a first cutting roller 4, a second cutting roller 5 and a winding roller 6 are distributed on the swing fixed disc 3 in an isosceles triangle shape, and the first cutting roller 4 and the second cutting roller 5 are horizontally arranged; a liquid outlet of the cutting liquid supply system 10 is disposed above the annular diamond wire 11 between the first cutting roller 4 and the second cutting roller 5, and is used for cooling the workpiece 12 and the annular diamond wire 11 and cleaning chips.
The swinging device 2 is characterized in that a swinging fixed disk 3 in the swinging device 2 is controlled by a servo motor to rotate back and forth clockwise and anticlockwise within a preset angle range by taking the center of the swinging fixed disk as the center of a circle, and a cutting roller I4, a cutting roller II 5 and a winding roller 6 which are arranged on the swinging fixed disk 3 are driven by the swinging fixed disk to drive an annular diamond wire 11 to swing; the servo motor controls the swing angle, the swing speed and the left-right swing frequency of the swing fixed disc 3 to realize the integral swing motion of the annular diamond wire 11 in the sawing area, so as to realize the cleaning of the cuttings in real time and the lubricating and cooling effects in the cutting area.
Specifically, the rotation angle of the swing fixed disc 3 takes the center as a symmetry axis, and the swing fixed disc rotates 5 to 45 degrees in the clockwise direction and the anticlockwise direction respectively. The specific setting of the rotation angle should be determined by the width of the part size to be machined, and the rotation angle should be such that the long annular diamond wire 11, which is more than half the width of the part to be machined, is rotated out of the part machining position to achieve the chip carrying out of the cutting parameters and to perform cooling and lubrication. Meanwhile, the rotation angle should be adaptively adjusted along with the change of the cutting depth.
For example, when cutting small-sized jewels waiting for machining parts, a rotation angle of 10 ° should be selected, and as the cut progresses, the feeder pushes the part to be machined like the center of the rocking fixed disk 3, and the rotation angle should increase to 15 ° as the pushing progresses. When roughly dividing a part to be machined or machining parts such as large raw stones, an initial rotation angle of 30 degrees should be selected, and as the cutting deepens, the rotation angle should be increased to 45 degrees along with the advancing process.

The breaking tension T of the annular diamond wire 11 is marked by the manufacturer when the factory leaves the factory.
In the present embodiment, the tension device 7 drives the winding roller 6 provided on the tension device 7 by a servo motor to apply a required process tension to the endless diamond wire 11 to ensure cutting accuracy and a service life of the endless diamond wire 8.
