When the device is working, the sample is fixed on the platform, and the material cutting is completed by the high-speed rotating cutting piece, and the spray head arranged at the fixed position is used to continuously spray cooling liquid to the cutting area to reduce the local temperature and reduce the thermal damage. This structure is relatively mature, easy to operate, and suitable for the preliminary cutting processing of various hard materials.

Especially when cutting high-hardness materials such as tungsten carbide at high speed, the local heat accumulation is serious, and the spray system cannot effectively follow up the cooling, which easily causes local overheating in the cutting area, and further affects the sample edge quality and analysis accuracy.

[0029] Working Principle: When using a supersonic tungsten carbide coating sample rapid cutting device, first open the protective glass cover 3 located on top of the device, and accurately place the tungsten carbide coating sample to be cut between slider 7 and slider 10. Slider 7 and slider 10 are precisely matched by guide rails to achieve stable positioning of the sample. Then, the operator activates the clamping mechanism to firmly clamp the sample, preventing it from shifting or being damaged due to vibration during the cutting process. Next, start the motor 15 located on one side of the device. The output shaft of motor 15 drives the saw blade 16 to rotate at high speed, completing the efficient cutting operation of the tungsten carbide coating sample. Because tungsten carbide material has extremely high hardness, a large amount of heat is generated during the cutting process, so the cooling system is activated simultaneously. To prevent overheating of the cutting area from causing sample ablation or deformation, coolant is pre-filled into the water collection box 5 at the bottom of the device. Driven by the water pump 20, the coolant is transported to the nozzle 22 through the water pipe 21. To improve cooling efficiency, the device is equipped with a dynamic spraying mechanism. At this time, the motor 14 starts and drives the rotating shaft 24 to rotate. The outer wall of the rotating shaft 24 is equipped with a connecting block 23, the end of which is connected to the connecting plate 18 on which the nozzle 22 is installed. The connecting plate 18 swings left and right under the drive of the rotating shaft 24, so that the nozzle 22 sprays the cutting area repeatedly for cooling, which greatly increases the coverage area and uniformity of the coolant, ensuring that the temperature of the cutting blade and the sample surface is controlled within a safe range, thereby improving the stability of cutting and the quality of sample processing.

[0030] Furthermore, to meet the batch cutting needs of tungsten carbide coated samples, the device is specially designed with a convenient saw blade 16 replacement mechanism to reduce maintenance downtime. The saw blade 16 is installed on the outer wall of the fixed block 3 28, which is connected to the output end of the motor 2 15 via the fixed block 4 29. When the saw blade 16 is worn and needs to be replaced, the operator only needs to rotate the fixed block 1 17, which is connected to the fixed post 2 26. The fixed post 26 is installed inside the fixed block 3 28 and is fitted with a return spring 27. By rotating the fixed block 1 17, the fixed post 26 is rotated and moved outward, so that it moves out of the fixing groove of the fixed block 4 29. Once the saw blade 16 is disassembled from the 30 slot, it can be easily removed and replaced. After replacing the saw blade 16, it is reinstalled on the outer wall of the fixing block 3 28. Then, the fixing post 26 is pushed into the fixing block 3 28. By rotating the fixing block 1 17, the fixing post 26 is re-engaged into the fixing groove 30. At this time, the spring 27 on the outer wall of the fixing post generates a rebound force under pressure, pushing the fixing block 1 17 to axially press the saw blade 16, thus achieving a quick and stable installation of the saw blade 16. This structure is simple in design and efficient in operation, significantly reducing the time and labor intensity required to replace the saw blade 16, thereby improving the overall working efficiency and continuous processing capacity of the equipment.
