安徽What are the standards for selecting materials for non-standard cutting tools?

Non standard tools refer to tools that do not meet general standards and are often customized according to specific needs. They have a lot of attention to material selection. Below, we will introduce the relevant issues of non-standard tool material selection from three aspects: tool usage environment, tool performance requirements, and material characteristics.

Firstly, the tool usage environment is one of the important factors in selecting materials.

Tools may be used in different environments, such as high temperature, low temperature, humidity, acid and alkali, and other special environments. In high-temperature environments, cutting tools need to choose high-temperature alloy materials, such as tungsten molybdenum alloy, tungsten titanium alloy, etc., to ensure the stability and lifespan of the cutting tools. In low-temperature environments, cutting tools need to have good low-temperature toughness and cold brittleness resistance, and low-temperature alloy materials such as alloy steel and stainless steel are often chosen. In humid environments, cutting tools need to have corrosion resistance, and materials such as stainless steel and high-speed steel are generally chosen. In acidic and alkaline environments, cutting tools need to choose materials with good corrosion resistance, such as special alloys, high hardness alloys, etc.

Secondly, the performance requirements of the cutting tool are also important factors in selecting materials.

The performance requirements of cutting tools involve aspects such as hardness, toughness, and cutting performance. Hardness determines the wear resistance and cutting performance of the cutting tool, and the hardness of the material needs to be considered when selecting materials. Generally speaking, materials with higher hardness have good wear resistance, but lower toughness and are prone to fracture; Materials with lower hardness have better toughness, but poor wear resistance. Therefore, it is necessary to weigh and consider selecting appropriate materials based on specific cutting requirements. The cutting performance of the cutting tool determines the cutting efficiency and quality. Generally, materials with good cutting performance are selected, such as high-speed steel, hard alloy, etc. Toughness is one of the important properties of cutting tools, especially for some non-standard tools, which require a large amount of customized processing, cold processing, etc. Therefore, toughness is particularly important for non-standard tools.

Finally, the characteristics of the material are also important considerations in selecting the material.

Different materials have different characteristics, such as strength, plasticity, magnetism, thermal conductivity, etc. According to the specific use of the cutting tool, it is necessary to select materials with specific characteristics. For example, for tools that need to withstand very large forces and vibration loads, it is necessary to choose materials with high strength and vibration resistance; For tools that require high-precision cutting, it is necessary to choose materials with good hardness and rigidity. In addition, for some special purpose knives, such as medical knives, food processing knives, etc., non-toxic, odorless, and harmless materials need to be selected to ensure the safety of the product.

In summary, the material selection of non-standard cutting tools needs to consider factors such as the tool usage environment, tool performance requirements, and material characteristics. When selecting materials, it is necessary to comprehensively consider various factors, weigh the advantages and disadvantages of various factors, and select the most suitable material to ensure that non-standard cutting tools have good performance and lifespan.
