Cold-pressed sintered diamond segment is a kind of diamond cutting tool prepared by cold-pressed and sintering process, so how to improve the sharpness of this kind of diamond segment? There are mainly the following 18 ways to solve:
1. Choose the right diamond particles: The shape and size of the diamond particles will directly affect the sharpness of the diamond segment. Choosing diamond particles with a sharper shape and smaller size can improve the cutting performance and sharpness of the diamond segment.
2. Optimizing the sintering process: The control of parameters such as temperature, pressure and time during the sintering process has an important impact on the performance and sharpness of the diamond segment. By optimizing the sintering process, a better combination of diamond particles and metal bonding phase can be achieved, and the hardness and sharpness of the diamond segment can be improved.
3. Structural design of the diamond segment: Reasonable design of the diamond segment structure can improve the sharpness of the diamond segment. For example, increasing the number and density of cutting edges and reducing the gap between cutting edges can increase the contact area of diamond particles during cutting and improve sharpness.
4. Use appropriate tool grinding technology: For the manufactured diamond segment, the sharpness can be further improved by using appropriate grinding technology for subsequent processing. By choosing a suitable grinding process and grinding material, the surface of the diamond segment can be effectively ground to make the cutting edge of the diamond segment sharper.
5. Regular maintenance and repair: The diamond segment will gradually wear out during use, affecting the sharpness. Regular maintenance and repair of the diamond segment can restore the sharpness of the diamond segment. For example, grinding, barasive or re-sintering of the diamond segment can be carried out, so that the diamond segment can regain better sharpness.
6. Surface coating of the blade: By applying a coating on the surface of the blade, the hardness and wear resistance of the blade can be increased, thereby improving the sharpness and service life. Commonly used coatings include titanium coating, TiN coating, TiCN coating, etc.
7. Select appropriate cutting parameters: cutting parameters include cutting speed, feed speed, cutting depth, etc. Adjusting these parameters can optimize the cutting process, reducing heat and wear while cutting, thereby maintaining the sharpness of the cutting edge.
8. Using advanced processing technology: Using advanced CNC machine tools, grinding equipment and cutting machinery, combined with high-precision processing technology, can achieve more precise tool manufacturing and cutting processes, thereby improving sharpness.
9. Choose high-quality diamond particles: High-quality diamond particles have better crystallinity and shape, which can provide higher hardness and sharpness. Choose diamond grains that are screened and sorted for more consistent cutting performance and sharpness.
10. Continuous tool improvement and innovation: Through continuous research and development and tool improvement, explore new materials, new processes and new tool designs to meet the needs of different industries and applications, and improve the sharpness and performance of the diamond segment.
11. Optimize the distribution of diamond particles: During the preparation process of the diamond segment, through reasonable diamond particle distribution design, the cutting edge of the diamond segment can be made more uniform and the sharpness can be improved. This can be achieved using layered assemblies or specific diamond grain arrangements.
12. Appropriately increase the content of diamond particles: increasing the content of diamond particles can improve the hardness and sharpness of the diamond segment. However, it should be noted that too high diamond particle content may cause the diamond segment to be brittle or difficult to process, which needs to be controlled within an appropriate range.
13. Adopt advanced sintering process: The sintering process has an important influence on the sharpness of the diamond segment. By optimizing parameters such as sintering temperature, holding time and pressure, the bonding degree of diamond particles and the compactness of the diamond segment can be improved, thereby improving the sharpness.
14. Strengthen the blade design of the diamond segment: Optimizing the geometry and structure of the blade can improve the cutting efficiency and the sharpness of the diamond segment. For example, adopting a serrated blade design can increase the cutting edge and improve the cutting effect.
15. Choose the right segment shape: Different shapes of diamond segments are suitable for different cutting tasks. According to the specific application requirements, choosing the appropriate shape of the diamond segment can improve the cutting efficiency and sharpness. For example, choose a slimmer segment for finer cuts, and a wider tip for faster cutting.
16. Use appropriate cooling lubricants: Using appropriate cooling lubricants during the cutting process can reduce the cutting temperature, reduce the wear of the diamond segment, and improve the sharpness. Cooling lubricants can effectively reduce friction and heat build-up, keep the cutting surface clean, and thus improve the cutting effect of the diamond segment.
17. Optimize the matching between the diamnd segment and the workpiece: different types of workpieces may require different characteristics of the diamond segment to achieve the best cutting effect. According to the hardness, shape and characteristics of the workpiece, select the appropriate diamond segment material and blade design to achieve better cutting effect and sharpness.
18. Maintain a good working environment for the diamond segment: When using the diamnd segment, ensure that the working environment of the diamond segment is clean, stable and at an appropriate temperature. Keep the diamond segment away from hard objects or harmful substances, which may damage the diamond segment or lose its sharpness.
