One of the most important parts in the kitchen is a knife. With it, we can cut vegetables into the shape we want, which is more convenient to make. Therefore, the role of knives in the kitchen is very important. Where's the diamond knife? What are the selection methods of diamond tools? Let's introduce it to you.

First, what about diamond tools?

1. Diamond tools have the advantages of extremely high hardness and wear resistance, low friction coefficient, high elastic modulus, high thermal conductivity, low thermal expansion coefficient and low affinity with non-ferrous metals. It can be used for precision machining of non-metallic hard and brittle materials such as graphite, high wear-resistant materials, composite materials, high-silicon aluminum alloys and other ductile non-ferrous metal materials. There are many kinds of diamond tools, and their performances are significantly different. Different types of diamond tools have different structures, preparation methods and application fields.

2. Natural diamond tools are mainly used for ultra-precision mirror machining of precious metals such as copper and copper alloys, gold, silver and rhodium, and special parts, such as VCR disks, optical plane mirrors, polygon mirrors and secondary mirrors. However, its crystallization is anisotropic and the tools are expensive. The performance of PCD depends on the content of diamond particles and cobalt, and the tool life is 10 ~ 500 times that of cemented carbide (WC matrix) tools. It is mainly used for turning various non-ferrous metals such as aluminum, copper, magnesium and their alloys, cemented carbide, fiber plasticizing materials with strong wear resistance, metal matrix composites, wood and other non-metallic materials.

Second, how to choose diamond tools?

1. Anyone who has used a knife knows that the sharper the blade, the easier it is to decompose food. Therefore, when selecting tools, check whether the blade is sharp, straight and seamless. At present, there are many kinds of cutting tools on the market. According to the material, it can be divided into steel, stainless steel, carbon steel, ceramics and so on. Actually, the higher the hardness, the higher the sharpness. Because the "speed" of a kitchen knife also depends on the degree and softness of the cutting edge.

2. For kitchen knives, high hardness is the first condition. The tool removes material from the workpiece, so the material of the tool should be harder than that of the workpiece. Secondly, the tool has the characteristics of high strength and toughness. The material of the cutter has great cutting force and impact force when cutting, so the cutter must have high strength and toughness. It is very important for the tool material to have wear resistance and heat resistance, because the tool is used to cut other things and must have higher wear resistance than other things, and heat resistance is a good embodiment of its deformation factors.

Many people don't know much about the materials of knives in the kitchen. Diamond knives are better, so how to buy diamond knives and how to buy them? I want to see the introduction of the above small series. Everyone knows this.
