The wear resistant ceramic lining tile is generally made according to the mold during production, and the shape of the wear-resistant ceramic tile is relatively regular, so it needs to be cut during the construction process. However, it is difficult to cut alumina ceramic tile, because the hardness of alumina ceramics liner is high, and the Rockwell hardness of alumina ceramic linings with an alumina content of more than 92% is above 80, and the hardness of general grinding wheels is not as big as it. It cannot be cut, only with a diamond saw blade.
We use diamond blades with high hardness for cutting. There are large desktop and handheld cutting machines, as long as they are well protected during cutting, do not cut the skin by the cut pieces. Then talk about how to cut, this is the key point. But our technicians told us that when the high-speed rotating blade contacts the wear-resistant ceramic liner at the center, the ceramic plate will be broken due to the shear stress. Therefore, the knife must be cut from the end, so that the stress can be minimized and it will not affect the cutting of the wear-resistant ceramic liner.
The last thing is to pay attention to the cooling of the cutting blade. When cutting such a hard material, the temperature of the blade rises rapidly, which will lead to a decrease in the strength of the blade, so pay attention to cooling the blade with water. In addition, I would like to remind you: when cutting, we recommend decomposing the drawing, and then cutting the ceramic size, shape and angle we need according to the drawing
