The difference between marble saw blade and granite saw blade
Publish Date:2020-11-09
Regarding the difference between granite saw blades and marble saw blades, to talk about this issue, we have to start with the stone properties of granite and marble.Both granite and marble are popular stones and are widely used in construction, from floor tiles to wall panels, from exterior walls to interior walls, as well as door covers and window grilles, background wall art decoration, etc., both of which are widely used. Natural stone, it can be said that these two types of materials will definitely be involved in high-end furniture decoration.
But many people can't distinguish the difference between granite and marble, but the difference between granite and marble is quite big. Experienced stone processing personnel can easily separate the two types of stone. For example, from the perspective of patterns, the lines of granite are spots-like, and the lines of marble show colorful patterns, which are particularly beautiful. To use a metaphor, granite is like embroidery, with little patterns forming beautiful patterns, while marble is like ink painting. The color is more integrated and the picture is more natural. It can also be distinguished from the hardness of the rock. Marble is a soft stone, and granite is a medium-hard stone. In terms of hardness, granite is higher than marble. The hardness determines the water absorption and structural stability of the stone. So outdoor people I like to use more stable granite, while interior decoration is decorated with more natural-colored marble. Of course, in terms of rock types, marble is metamorphic rock, while granite is magmatic rock. In addition, the colors of marble are diverse and colorful, while most of the granites are relatively single in color, mostly gray and white, and few yellow, red, and green stones.
Having said so much, they are actually talking about a problem. Marble is different from granite. Marble is a carbonate-like rock that is degenerated or deposited. The structure is fine, solid, polishable, and has a wide variety of colors, with beautiful natural colors and low radiation. Because it is not resistant to weathering and is rarely used outdoors, small-diameter marble saw blades are usually used for interior decoration, and medium-diameter saw blades are used in stone factories. Because marble is more beautiful, its patterns are rich, the color is soft, etc., after laying it and disposing of it, it will appear high-grade, rich and gorgeous. This puts forward higher requirements for the processing of marble, and the cutting requirements for marble saw blades are much higher than those for granite saw blades. Because marble is expensive, it is not allowed to collapse or drop corners.
Granite is harder and easier to maintain. But it gives a feeling of coldness, and it is generally used on the ground and walls of outdoor or public areas. Therefore, most customers have less requirements for the cutting accuracy of granite saw blades than marble saw blades. However, there are many varieties of granite. In order to better adapt to the granite varieties in various regions, the types of granite saw blades are extremely wide. The hardness of granite ranges from soft, medium, hard to super hard, and the hardness spans a large range, generally based on the quartz composition of granite and calcium carbonate to determine the hardness of granite.
So what is the difference between a marble saw blade and a granite saw blade?
First: Marble saw blades are more expensive. The price of marble is more expensive, but with low hardness, it has high abrasiveness, so a sharper segment is needed, so the cost of the segment will increase.
Second: In order to enhance the cutting effect of marble saw blades, there are changes in the number of cutting teeth, especially for mid-diameter saw blades. The difference in saw teeth is very obvious.
Third: Marble has high abrasiveness, so the thickness of the blade is generally higher than that of granite blades. Therefore, compared with granite saw blades, marble saw blades have the characteristics of higher efficiency but faster loss.
So what happens if you cut granite with a marble saw blade? It may not be able to cut, because the Mohs hardness of the marble segment is not high, the loss of matrix bond will not keep up with the loss of diamond in the granite cutting process, and naturally it will not be able to cut. The life of the blade is rapidly shortened. How about cutting marble with a granite saw blade? Because of the abrasiveness of marble and the low sharpness of granite saw blades, it will cause stone breakage, chipping, and stone scratches and stone injuries.
