Description

Technical Field

[0001] The present invention belongs to the technical field of target processing, and relates to a processing method for molybdenum targets. Background Art

[0002] Usually, cutting fluid is used for the processing of molybdenum targets. The cutting fluid can play a role in cooling and lubricating during the processing, thereby improving the processing efficiency and quality. However, this method has some problems. First, the use of cutting fluid will cause environmental pollution. The use of cutting fluid will also increase the processing cost, reduce the production efficiency, and cause difficulties in the recovery of molybdenum chips and low value. Therefore, how to achieve efficient and high-quality processing of molybdenum targets without using cutting fluid is an important problem faced by the current technology. Summary of the Invention

[0003] To solve the above technical problems, the present application provides a processing method for molybdenum targets. This processing method can achieve efficient and high-quality processing of molybdenum targets without using cutting fluid, avoid the environmental pollution caused by the use of cutting fluid, and improve the recovery value of molybdenum chips.

While the composite air source can make the cooling speed of each surface of the molybdenum target similar during the processing, improving the processing effect; at the same time, the air source in the other direction can increase the diffusion channel of the cross-direction air source, improve the heat dissipation speed, and further improve the cooling effect, so as to achieve a cooling effect similar to that of the coolant and avoid the use of the coolant.

[0068]

[0069] As can be seen from the test results in Table 1, for the processing method of the molybdenum target material provided in Embodiments 1-5 of the present application, without using cutting fluid but using air cooling, the processing qualification rate can be as high as 100%.
