According to calculations, the contribution rate of technological progress to energy conservation reaches 40% -60%. Therefore, during the 12th Five Year Plan period, how to promote energy conservation and emission reduction will become a top priority for the development of China's economy and social harmony.   In recent years, with the booming development of the server industry, high-performance circular blades have become an important tool for the rapid development of various industries in society. High performance computing and other high energy consuming applications have also become prominent areas of social energy consumption resources, and have become the focus of attention for major enterprise users. The growth rate of high-performance industries shows an upward trend every year, especially in the circular blade market. The immature server industry has already occupied an important high ground, and the circular blade market is becoming the fastest growing and most prominent field in the overall server market.   From the perspective of development trends, how to align the use and development of circular blades with the energy-saving and emission reduction goals of the 12th Five Year Plan has become a focus of consideration for the high-performance industry. According to industry research experts, circular blades are currently extending from the high-end market to the low-end market, and a situation of comprehensive penetration into the aggressive server market is gradually forming. As an important market for server applications, China has seen an increasing number of brands entering the Chinese market. Whether it is a well-known foreign brand or a conservative domestic server manufacturer, energy conservation and low consumption have always been important considerations for many manufacturers in their design and research and development.

In addition to good tool coatings and cutting fluids, there is also a new process of cutting off the thermal current circuit.   As is well known, during the metal cutting process, high temperatures are generated in the cutting area due to chip deformation and friction. At the same time, due to the different materials of the tool and workpiece, the two poles of the thermocouple are formed, generating thermoelectric potential and direct current. Thermoelectric current can easily enhance the oxidation process on the working surface of cutting tools, accelerating tool wear. Under certain conditions, thermoelectric potential - thermoelectric current - will also be generated in the contact areas between the tool and the machine tool, the workpiece and the machine tool, and the contact areas between the friction pairs of the machine tool itself. During the cutting process, thermal magnetic and electromagnetic effects are also generated, and electron emission discharge phenomena occur on the surface of the high-temperature contact area.   In recent years, research by domestic and foreign scientific and technological personnel has shown that the thermal current generated during the cutting process and the thermoelectric current caused by other factors both form a circuit through the machine tool tool workpiece machine tool system. At the same time, there is also local thermal current circulating in the limited contact area between the tool and the workpiece, which exacerbates the wear of the tool. Therefore, in addition to the basic methods mentioned above, a new approach can also be adopted to improve the cutting performance and durability of cutting tools, which is to combat the thermoelectric current effect that enhances tool wear by cutting off the thermoelectric current circuit.   The method of cutting off the thermal current circuit is very simple. Even if the tool is insulated from the machine tool or the workpiece is insulated from the machine tool, the thermal current cannot pass through the cutting area and form a circuit. This can reduce the affinity between metals, reduce the generation of chip deposits and scales, and improve the cutting performance, durability, and machining quality of the tool.   How to cut off the thermal current circuit. For machinists, use a rubber wood pad or plastic pad on each of the upper and lower surfaces of the turning tool to insulate the upper and lower planes and sides of the tool holder from the square tool holder on the machine tool; For milling and planing workers, if a flat jaw clamp is used to clamp the workpiece, a rubber board or rubber sheet is placed between the clamp and the workpiece to insulate the workpiece from the flat jaw clamp; For drill bits and end mills, high-strength plastic handle drill bits and plastic handle end mills can be used to insulate the tool holder from the spindle hole of the machine tool.   Through production practice, it has been proven that cutting off the thermal current circuit is particularly suitable for processing high-strength, high hardness, and difficult to cut materials in order to demonstrate its effectiveness, usually improving tool durability by 1-2 times. Therefore, it is the simplest and easiest to implement effective method.

To have a better understanding of this type of shearing machine blade, one needs to have a certain understanding of its material. However, for such a question, I don't know how much you know, and for those of us who are not familiar with this type of machine, we may not be very clear. Now let professionals introduce us to the materials of shearing machine blades.   1、 The blade can be made of carbon bonded tool steel   This type of carbon steel can usually be made from two types of steel materials, and the hardness that can be adapted to this type of blade is also within a certain range. It is generally suitable for use in some ordinary low-carbon cold-rolled plate processing. It also has the advantages of low cost and low price for this type of cutting machine blade, which is an important reason why many small processing workshops choose this type of blade.   2、 Selection of Low Alloy Tool Materials   There are many choices for the material of low-alloy tool steel. For blades made of this material, they have undergone heat treatment processing, and the hardness range they can use is relatively wide. In addition, for blades made of this type of shearing machine, there are also many industries that can be applied, and it can adapt to the processing and cutting of plates of different thicknesses during the cutting process.   The materials of the above shearing machine blades are also the most widely used materials nowadays. With the continuous development of our industry, the use of these shearing machine blades is also increasing. Therefore, many improvements have been made for this machine to better adapt to more developments. This can be seen from its material, and we hope that it can continue to innovate and improve to better serve us.

What are the reasons that affect the effectiveness of the slitting machine blade? How to use the pneumatic slitting machine, corrugated cardboard slitting machine, and metal slitting machine correctly in the production process to improve the efficiency and lifespan of the blades?   The material used for making knives is a key factor in the durability of slitting machine blades; Ordinary cutting blades for paper, plastic, and film should be made of SKD-11 alloy steel with high chromium content; High speed slitting machine blades require high wear resistance, so high-speed steel is the best cutting material;   In general, the durability of a blade is directly proportional to its heat treatment hardness; Therefore, high-quality slitting machine blades can achieve a hardness of HR55-60 after quenching treatment, while blades made of high-speed steel materials also need to undergo vacuum heat treatment to achieve ideal hardness and toughness.   The precision of blade grinding and the angle of the blade edge are also factors that affect the lifespan. Generally, slitting machine blades adopt a single blade edge design, with a grinding angle of around 30 °. Usually, the angled surface of the blade bears a relatively large frictional force during the cutting process. Under the friction of the paper edge, the inclined surface of the blade is quickly worn out. Considering the size of the cutting object's resistance to cutting force, the angle of the grinding edge should be minimized as much as possible.   When choosing a blade, the texture of the cutting material should be taken into consideration; The speed at which the cutting edge becomes blunt during the cutting process is related to the wear resistance of the material being cut. When cutting materials with harder texture and greater toughness, the texture and hardness of the selected slitting machine blades should be better.   Cutting machine blades are specialized blades used in the printing and packaging industries, and the cutting accuracy, sharpness, and service life largely affect the production efficiency of products; Reasonable selection of cutting machine blades can better increase the production efficiency of finished products and shorten the cutting time.
