How do diamond tools make your work more effective?

In the natural stone industry and related industries, diamond tools are widely used for cutting operations. One of the most widely used processing methods for diamond tool is called "sawing", which is not only widely used in the field of stone, but also in civil engineering. Therefore, turning tools must be used in the processing conditions of these industries. Diamond materials are also used in other processing in this field.

What are the characteristics and performance advantages of diamond tools?

The characteristics and performance of diamond tools are unique and especially suitable for processing hard and brittle materials, especially non-metallic materials, such as stone, wall and floor tiles, glass, ceramics, concrete, refractory materials, magnetic materials, semiconductors, gems, etc. It can also be used to process golden metals, alloys, woods, such as copper, aluminum, cemented carbide, composite wear-resistant wood boards, etc. At present, diamond tools have been widely used in building materials, petroleum geology, metallurgy, machinery, electronic ceramics, etc. According to their different uses, diamond tools are mainly divided into several categories: diamond grinding tools, diamond sawing tools, diamond cutting tools, and diamond drilling tools.

 

Take diamond cutting tools as an example to introduce the influence factors of diamond tools on work

In the front of the diamond tools particles during processing, the tension is caused by the tangential force. In this area, chips are generated due to stretching and pressure. This mode is called the initial formation of the diamond cutting tools, and the diamond tool cutting debris overflows through the front groove and the middle of the particle.

 

① The physical material properties of stone, such as: particle size and strength

② Force between diamond tool and material

③ Tension distribution in stone

④ Tool temperature of workpiece contact surface

⑤ The cutting edge is deformed due to the elasticity of the plastic workpiece

⑥ Friction between stone and diamond tool

⑦ Friction between stone and substrate

⑧ Friction between cutting chips and substrate

 

During the cutting process, the stone shows its expansion and contraction performance to increase the maximum tension, and the most important thing is to achieve the minimum cutting thickness. The material removed by the diamond tool is deformed due to the pressure derived from the lower part of the diamond. After the diamond particles consolidated on the tool are removed, elastic recovery will occur, resulting in critical stress, which will cause the hard shape to break. The pattern arising from the tensile pressure is named the chip tip formation of the second diamond tool. The result of the cutting process is the appearance of a large amount of chips, which play a cooling role for the machining process.

 

How to improve efficiency when working with diamond tools of different materials?

Natural gold drama stone (ND) knives

Natural diamond is the hardest substance in the known minerals, and it is mainly used to prepare cutting tools and turning tools. After fine grinding of natural diamond tools, the cutting edge radius can reach 0.01~0.002um. The cutting edge of the natural single crystal diamond tool is still observed to be smooth after a high magnification of 1500 times.

 

Polycrystalline diamond (PCD) tools

PCD diamond tool is a polycrystalline material synthesized by agglomerating and sintering diamond powder through a metal bond such as a drill under high temperature and high pressure conditions, also known as sintered diamond. The polycrystalline diamond tool is sintered into a milling cutter as a whole, which is used for milling processing. The PCD diamond tool crystal grains are arranged in a disordered state, and they are isotropic and have uniform hardness. The graphitization temperature is 550°C. The tool has high hardness, high thermal conductivity, and low heat. Coefficient of expansion, high modulus of elasticity and low coefficient of friction.

 

Artificial polycrystalline gold cluster stone composite (PDC) cutter

In order to improve the toughness and weldability of PCD blades, PCD and cemented carbide blades are often made into synthetic polycrystalline diamond composite blades (PDC). That is, a layer of 0.5~1mm thick PCD is sintered on the surface of the cemented carbide substrate. The bending strength of the composite diamond tool blade is basically the same as that of cemented carbide, and the hardness is close to PCD, so it can be used instead of PCD.

 

CVD diamond film (TDF) welding tool

The diamond thick film welding tool is to weld the laser-cut CVD diamond thick film to the substrate (usually K-type cemented carbide) to form a composite sheet, then polish the composite sheet, weld it to the cutter body twice, and sharpen it as needed The shape and cutting edge.

 

Diamond coated tools

Diamond-coated cutting tools are directly deposited with a layer of 1~25μm diamond film on cemented carbide (type K cemented carbide) or ceramics by CVD method, without isotropic cleavage surface. The hardness of the thin-film coating tool reaches 9800~10000HV. The thermal conductivity is high, and the thermal conductivity is as high as 2000Wm·K at room temperature, while the thermal conductivity of cemented carbide tools is only 80~100W/m·K.

 

An introduction to the attractive development prospects of diamond tools in my country.

l The gap between cities and towns is potential. The biggest development potential in the country in the next few decades lies in urbanization.

l The development of mechanical processing is a powerful driving force for the development of diamond tool

l Mineral exploration and railway construction are a powerful driving force for the development of diamond tools

 

The prospect is attractive, how should a journey of a thousand miles begin with a single step?

① Increase investment in the diamond tools industry, pay close attention to the development of new products and the promotion of new technologies and new processes, promote sincere cooperation between technical teams and production enterprises, and support some technical consulting and service units.

② In recent years, the demand for diamond tools in the processing fields of machinery, gems, medical equipment, wood, glass steel, stone crafts, precision ceramics and composite materials has increased year by year.

③ Strengthen the internal management of the enterprise, continuously improve the production process, take the road of groupization or joint enterprise, establish a leading enterprise, rely on the vast technology research and development team, guide the creation of national brands, and actively participate in international competition.

④ Accelerate the construction of authoritative testing institutions, gradually establish testing and inspection centers in various provinces and cities, and strictly control product quality in accordance with European, American, Japanese and Korean standards.

⑤ To improve the overall technical level of the diamond tools industry, we must start with high-quality materials, advanced technology and equipment.

⑥ Reasonably divide labor, organize large-scale production, and improve international competitiveness.
