In the coal mining industry, the working environment for coal mining equipment is usually quite harsh. As one of the main consumables, choosing a suitable cutter for the specific underground conditions is crucial for efficient coal mining.

In the coal mining industry, the working environment of coal mining equipment is usually quite harsh. As one of the main consumables, choosing a suitable cutting tooth for the underground working conditions is crucial for efficient coal mining.

1. The material is one of the important factors affecting the performance of cutting teeth. Therefore, it is essential to understand which material of cutting teeth is suitable for our coal mine's working conditions. The most common cutting tooth material on the market is hard alloy - 42CrMo, followed by other materials such as 35MnP.

2. The selection of cutting tooth models completely depends on the hardness of the coal rock and the model of the tooth holder of the coal mining machine or tunneling machine. Therefore, it is important to clarify these details in advance when purchasing! This way, the performance of the cutting teeth can be maximized, and operational costs can be reduced.

3. The technological process of the cutting teeth for coal mining machines is also one of the factors to pay attention to during the procurement process. The welding agent for the cutting teeth is generally determined based on the specific material of the tooth body and the working conditions. Additionally, the cutting teeth must undergo heat treatment processes, which are determined by the thickness of the wear-resistant layer, the amount of welding agent used, and the surface hardness requirements of the cutting teeth. These parameters need to be precise; if they are too large or too small, it will affect the hardness of the cutting teeth. Therefore, a mature manufacturing process is also very important.
