What are the requirements to pay attention to when selecting cutting materials for tunneling machines?

For those engaged in coal mining, cutting teeth are familiar equipment, because in coal mining, cutting teeth are the main tool for mining, which can ensure the quality and efficiency of coal mining. There are many types of picks, and different picks complete different tasks. However, the picks of the tunneling machine are mainly used to excavate coal mines and achieve mining.
Why are excavation machine picks so popular among numerous picks? I think many people have great doubts about this. So, let's take a brief look.
The reason why the cutting teeth of tunneling machines are so popular is mainly due to the quality and performance of the cutting teeth, but it has better quality and performance because of the selection of materials. For the production of picks, the selection of picks is crucial. Only by selecting high-quality materials as pick materials can the quality of picks be guaranteed.
The material used by the rotary excavator cutter manufacturer is stainless steel, but there are various types of stainless steel materials, and the performance of different types of stainless steel varies. Therefore, when selecting cutter materials, careful selection is necessary. So, what standards do we need to meet when choosing cutting materials?
1. Strong hardness
Cutting teeth play an important role in coal mining, so when selecting materials, attention should be paid to their hardness. The hardness of the coal mine being mined is very high, so the cutting teeth used should also have corresponding hardness. If the hardness of the cutting teeth is not good, how can coal mines be excavated? Meanwhile, the efficiency and quality of mining cannot be guaranteed.
II. Good resilience
The material selected by the rotary excavator cutter manufacturer must have good toughness to ensure the quality of the cutter. During the production process, materials will be made into corresponding shaped cutting teeth according to equipment requirements, so good toughness is required to produce good cutting teeth. But if the material has poor toughness, it will only affect the production of the cutting teeth.
III. Good wear resistance
Good wear resistance is also one of the standards to pay attention to when choosing materials. Because there will be friction between the cutting teeth and the coal mine during mining, if the cutting teeth are not wear-resistant, it will definitely affect the performance of the cutting teeth during mining. Therefore, when selecting cutting materials, it is important to pay attention to their wear resistance.
