Since the development of the super-hard materials industry in China, experts in the industry have been working tirelessly to study the method of sharpening the diamond saw blade. The sharpness and longevity of the road are the ultimate pursuit of the diamond saw blade. How to effectively improve the sharpness of the diamond saw blade?
The core of the performance of the diamond saw blade is the adjustment of the carcass structure performance, so that the carcass structure has sufficient mechanical holding force for the diamond, and also has the synchronous wear performance matched with the diamond. cut off disc for stainless steel
There are many factors affecting the sharpness of the diamond saw blade. The fundamental reason is that it is due to the adjustment of the tissue properties, and the quality of the tissue properties depends on the quality state of the metal powder and the sintering process.
Therefore, in essence, improving the sharpness of the diamond saw blade is to improve the quality of the metal raw material and the corresponding sintering process. From the current status of the diamond saw blade industry, the following measures can be taken:
1. Selecting iron powder with high purity, low oxygen content, uniform particle size distribution and high sintering activity;
2. Uniformity must be ensured when mixing, so as to ensure the uniformity of the microstructure of the diamond saw blade sintered body;
3. Reasonably match the particle size of the powder, and the coarse and fine powders cannot be piled up;
4, the formula design is reasonable, determine the appropriate copper-tin ratio design, control the mechanical properties of the sintered body;
5, theoretical density calculation and feeding amount should be controlled accurately to ensure the compactness of the carcass.
