Choosing the best diamond saw blade for cutting tiles

Ceramic tile is a common decoration material in our daily life. It is widely used in the construction industry. When using ceramic tiles, it is often necessary to cut it to achieve the best.

The general name of the saw blade for cutting ceramic tiles is the diamond saw blade. The diamond saw blade is a cutting tool that is widely used in the processing of hard and brittle materials such as concrete, refractory materials, stone, and ceramics.

When processing ceramic tiles, the skill of the workers affects the quality of the processing, and the quality of the diamond saw blade also affects the quality of the ceramic tiles.

Then Choosing the best diamond saw blade for cutting tiles, generally speaking, different types of diamond saw blades are used for different materials, and different powder formulations are suitable for the characteristics of different materials, which directly affect the quality, effect, pass rate, and even cost-effectiveness of the material . product.

Choosing the best diamond saw blade for cutting tiles, as follows:

1. The choice of diamond particle size

When the diamond grain size is coarse and single grain size, the saw blade tip is sharp and the sawing efficiency is high, but the bending strength of the diamond agglomeration is reduced;

When the diamond particle size is fine or coarse and fine particle size are mixed, the durability of the saw blade bit is high, but the efficiency is low. Considering the above factors, it is more appropriate to choose a diamond particle size of 50/60 mesh.

2. Selection of diamond distribution concentration

Within a certain range, when the diamond concentration changes from low to high, the sharpness and cutting efficiency of the saw blade gradually decrease, while the service life is gradually extended;

However, if the concentration is too high, the saw blade will become dull. However, with a low concentration and coarse particle size, the efficiency will be improved.

Using the different functions of each part of the cutter head during sawing, using different concentrations (that is, the middle layer can use a lower concentration in a three-layer or more layer structure), and the middle groove is formed on the cutter head during the sawing process. It is helpful to prevent the saw blade from swinging, thereby improving the quality of stone processing.

3. The choice of diamond strength

The strength of diamond is an important indicator to ensure the cutting performance. Too high strength will make the crystal not easy to break, the abrasive grains will be polished during use, and the sharpness will decrease, resulting in deterioration of tool performance;

When the strength of diamond is not enough, it is easy to break after being impacted, and it is difficult to bear the heavy task of cutting. Therefore, the strength should be selected at 130~140N.

4. The choice of binder phase

The performance of the saw blade does not only depend on the diamond, but depends on the overall performance of the composite material of the cutter head formed by the proper cooperation of the diamond and the binder.

For soft stones such as marble, the mechanical properties of the cutter head are required to be relatively low, and copper-based binders can be used. However, the copper-based binders have low sintering temperature, low strength and hardness, high toughness, and low bonding strength with diamond. .

When adding tungsten carbide (WC), use WC or W2C as the framework metal, with an appropriate amount of cobalt to improve the strength, hardness and bonding characteristics, and add a small amount of Cu, Sn, Zn and other metals with low melting point and low hardness for bonding The particle size of the main ingredients should be finer than 200 mesh, and the particle size of the added ingredients should be finer than 300 mesh.

5. Selection of sintering process

As the temperature increases, the densification degree of the carcass increases, and the bending strength also increases, and with the extension of the holding time, the bending strength of the blank carcass and diamond agglomerates first increases and then decreases. 120s sintering process at 800℃ to meet performance requirements.
