Which One is Better, Silicon Carbide Sandpaper or Diamond Grinding Disc?

In the wide range of consumables, there are many consumables with the same function, such as silicon carbide sandpaper and diamond grinding disc. These two consumables are used for the rough grinding of samples. Many newcomers are confused about the selection of sandpapers with similar functions. RMC ABRASIVE will introduce how to make the right choice between the sic sandpaper and diamond grinding disc.


Ⅰ. How to choose silicon carbide sandpaper and diamond grinding disc?


In the preparation of consumable samples, in addition to cutting and inlaying, the key step is the grinding and polishing process. In this way, the cutting does not produce deep, irremovable defects, and the mosaic is also correct, then the key lies in the grasp of the grinding and polishing process. In the case of proficient sample preparation techniques, the quality of sample preparation depends on whether the consumables selected for each grinding and polishing process are appropriate. Silicon carbide sandpaper and diamond grinding discs are both used for the rough grinding process, but there are still differences in application. If you understand these differences, you can choose them appropriately.


Ⅱ. The characteristics of silicon carbide sandpaper and diamond grinding disc


The grinding particles of the diamond grinding disc are diamonds, the particle size is from 240μm-6μm. It is especially suitable for the preparation of samples of high hardness or superhard materials such as ceramics, glass, thermal sprayed metal coatings, cemented carbides, etc., for materials with hardness higher than 150HV. A diamond grinding disc can replace at least 100-200 pieces of silicon carbide sandpaper. Thus, the advantages of the diamond grinding disc can be demonstrated. Generally, when using a diamond grinding disc for rough grinding, different from using silicon carbide sandpaper, which at least needs 2 to 3 marks for the grinding process, it only needs one step. The removal rate is high, wear resistance and good grinding performance are maintained. With good durability, it is easy to obtain samples with perfect edge retention and flatness. And this is the application characteristic of the diamond grinding disc.


The abrasive particles of silicon carbide sandpaper are are silicon carbide particles, with a particle size ranging from 260μm-5μm. For materials with a hardness of less than 150HV or a slightly harder material with good ductility, it is appropriate to choose silicon carbide sandpaper for coarse grinding. It is easy to remove the material to obtain a uniform surface finish.


To sum up, compared with the diamond grinding disc, silicon carbide sandpaper is different in the rough grinding application depending on the hardness of the material. The diamond grinding disc is suitable for the preparation of material samples with a hardness range of 150HV and above, and the hardness range is below 150HV, or the hardness is high but the ductility is better, it is best to use silicon carbide sandpaper for sample preparation.


Dear customers, if you understand the characteristics of silicon carbide sandpaper and diamond grinding disc, you can use them properly in actual work. We hope that what we just shared can bring you some help.
