Now the wide range of electrical applications, technology in these years is how the use of it, with the development of the industry is now faster and faster, in many ways, now the role of precision machining is still very obvious, demagnetizer is used to eliminate the residual magnetism generated by machining of a device, it is generated by the electromagnetic coil magnetic lines, directly or indirectly through the magnetic lines of the original workpiece magnetism to interfere with the workpiece demagnetization. The main demagnetizers in our country are platform demagnetizer and frame demagnetizer. The platform type demagnetizer is mainly used to demagnetize the workpiece by introducing the magnetic flux of the coil to a flat surface through the iron core. Frame demagnetizers are mainly used to demagnetize the workpiece by passing the magnetic lines through the workpiece inside the coil to cut the remanent magnetism of the workpiece. The demagnetizer requires an AC current to magnetize the coil. Demagnetizer can be used as a demagnetizer and other equipment after modification. I hope the above precision machining related to the introduction can help you, in the machinery industry market competition is increasingly white today, choose a high-tech, high-precision processing, high service quality, high reputation of machining partners is an important part of future development! The main appearance of the finishing process, such as grinding, honing, fine grinding, rolling processing, etc., should be placed at the end of the process route stage. The development of precision parts machining process route general principles, precision parts machining process procedures, can be broadly divided into two links. First is to develop the process route of parts processing, and then determine the process size of each process, the equipment and process equipment used, as well as cutting specifications, work quotas.

In the future, with the development of China's construction machinery industry, to provide users with high performance, high reliability, high mobility, good maintenance and economy of the equipment gradually become the goal of manufacturers to chase. Therefore, in order to meet the user's individual needs, manufacturers production should take a multi-species, small batch production method, to the fastest speed to develop new products of high quality and low cost. The most effective way to achieve the above requirements is to use modular design principles, methods and technologies. Now the application of mechanical spare parts processing is also more and more, and in the parts these above, the application to the range is also very wide, no matter how to say, improve the safety of man and machine, driving comfort, convenient for the driver to operate and technical maintenance, so as to improve the working conditions of the driver, but also improve the production efficiency, some countries on the construction machinery vibration, noise, exhaust emissions and anti-rollover and falling objects to develop a new The range of mechanical spare parts processing, and precision must also be high, why, because the customer's demand for quality is also quite high. Do you think the quality of mechanical spare parts processing, customers will choose, from the point of view of our choice of products, all choose a good product, which is now a lot of people's ideas.

Precision machining industry has become more and more competitive in recent years, many small businesses and OEM workshops have withdrawn from the market stage, while the companies left behind unless they have been transformed and innovative, most are still struggling. In such an environment, precision machining factory how to make salesmen looking for customers, access to a steady stream of orders, we need to abandon the inherent thinking. Welding: also known as fusion, fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by means of heat, high temperature or high pressure. Welding achieves the purpose of joining in three ways. 1, fusion welding - heating the workpiece to be joined so that it melts locally to form a molten pool, which is joined after it cools and solidifies, and can be assisted by adding molten filler if necessary, it is suitable for welding processing of various metals and alloys, and does not require pressure. 2、Pressure welding - the welding process must apply pressure to the welded parts, and it belongs to the processing of various metal materials and some metal materials. 3、Brazing - using metal materials with lower melting point than the base material as brazing material, using liquid brazing material to wet the base material, fill the joint gap and realize linking weldments by diffusing with each other with the base material. It is suitable for welding and processing of various materials, as well as for welding and processing of different metals or dissimilar materials. There are various modern sources of welding energy, including gas flame, electric arc, laser, electron beam, friction and ultrasonic waves. In addition to being used in factories, welding can be performed in a variety of environments, such as in the field, underwater and in space. Wherever welding is done, it can pose a hazard to the operator, so proper precautions must be taken when welding is performed. Possible injuries to the human body from welding include burns, electric shock, vision impairment, inhalation of toxic gases, and excessive UV exposure.

Casting properties: refers to whether the metal or alloy is suitable for casting some process properties, mainly including flow properties, the ability to fill the mold; shrinkage, castings, mechanical parts processing The ability of volume shrinkage during solidification; deviation refers to the chemical composition unevenness. Welding performance: refers to the metal material by heating or heating and pressurized welding method, two or more metal materials welded together, the interface can meet the characteristics of the purpose of use. Top gas section performance: refers to the performance of the metal material can be granted top forging without rupture. Cold bending performance: refers to the metal material at room temperature can withstand bending and not break performance. Bending degree is generally used to bend the angle α (outer angle) or bending center diameter d on the ratio of material thickness a, a larger or d / a smaller, the better the cold bending of the material. Stamping performance: the ability of metal materials to withstand stamping deformation processing without rupture. Stamping at room temperature is called cold stamping. The test method is to test by cupping test.   Forging performance: the ability of a metal material to withstand plastic deformation without rupture during forging and pressing processing.

Aluminum alloy deep processing is a mechanical processing method that uses digital information to control parts and tool displacement, and it is the application of CNC machine tools to stop parts processing. What is deep processing of aluminum alloy? Processing of aluminum alloy parts 1、 What is aluminum alloy deep processing 1. Oxidation treatment of aluminum alloy, silver white surface of industrial aluminum profiles, oxidation, beauty, corrosion resistance 2. Aluminum alloy extrusion. Each aluminum profile with different specifications has a corresponding production and development mold, which turns the aluminum material into a mold and forms the required aluminum profile through continuous extrusion. 3. Aluminum alloy casting. The casting of industrial aluminum profiles is also similar to the ancient iron making technology. 4. Impurities in aluminum alloy smelting. The purity of aluminum is getting higher and higher, and the performance is better. Therefore, some impurities can be removed through various heating furnaces to improve the performance of aluminum profiles. 5. The composition of aluminum alloy increases the hardness of products. We know that industrial aluminum profiles are aluminum alloy profiles, including aluminum magnesium silicon alloy, aluminum zinc alloy, etc. This can increase the hardness and bearing capacity of aluminum profiles. Deep CNC processing of aluminum alloy 2、 Characteristics of aluminum alloy deep processing: Electrolytic coloring of aluminum profiles has been widely used at home and abroad due to its good decorative properties, especially in the surface treatment of architectural aluminum profiles. What are the three characteristics of aluminum alloy deep processing? 1. Low hardness of aluminum alloy Compared with titanium alloy and quenched steel, aluminum alloy has lower hardness. Of course, heat treated or die cast aluminum alloy also has higher hardness. The HRC hardness of ordinary aluminum plate is generally below HRC40. Therefore, in the case of aluminum alloy processing, the tool load is small. In addition, aluminum alloy has excellent thermal conductivity, so the cutting temperature of aluminum alloy milling is low, which can improve the milling speed. 2. Low plasticity of aluminum alloy Aluminum alloy has low plasticity and low melting point. When processing aluminum alloy, the separation edge problem is very deep, the chip removal performance is poor, and the surface roughness is also high. In fact, the main reason for processing aluminum alloy is that the effect of knife and roughness is not good. If the two problems of fixed blade and quality of machined surface are solved, the problem of aluminum alloy machining can be solved. 3. Tools are easy to wear Due to the use of unsuitable tool information, there are many situations where tool wear is accelerated due to problems such as rod edge and chip discharge when aluminum alloy is processed.

cnc machining multi workpiece methods include: drilling, turning and boring, milling, grinding and shaping. No matter the CNC machine tools are large or small, simple or complex, they can be divided into five categories. Auto parts processing 1. Drilling Drilling is the process of drilling holes in solid metal using a rotary bit called a fried dough twist drill. CNC lathe used for drilling is called drilling machine. There are also many kinds and specifications of drilling machines. In addition to drilling, the drilling machine can also perform other processing. When drilling, the workpiece is clamped and fixed. The drill bit rotates while drilling into the workpiece. 2. Turning The general lathe is the most commonly used machine for turning parts. Turning is the removal of metal from a workpiece. When the workpiece rotates, the tool cuts along the workpiece. Boring is a method of enlarging or further processing holes drilled or cast in metal workpieces. Boring on the lathe is completed by a single edge tool, which rotates while feeding the workpiece. 3. Milling Milling is the process of turning tools to cut metal. This kind of cutter has multiple cutting edges and is called milling cutter. Auto Hub Parts Processing 4. Grinding Grinding is a method of removing metal using a wheel called a grinding wheel. The workpiece is finished by grinding. The workpiece size after grinding is accurate and smooth. When grinding a circular workpiece, the workpiece rotates and feeds the rotating grinding wheel. When grinding a flat workpiece, the workpiece moves back and forth while the grinding wheel rotates. Grinding process is to finish the hard workpiece after heat treatment to achieve accurate size. 5. Shaping CNC processing: Single blade cutter is used for air gouging, gantry cutting and grooving machine precision plane. When the forming machine is used for processing, the workpiece feeds the cutter and the cutter moves back and forth on the workpiece. When using gantry cutting, the tool cuts or feeds the workpiece, and the workpiece moves back and forth under the tool. In order to meet the market demand, many CNC machining manufacturers are equipped with huge tool libraries to cover the precision and strength of machined parts. The method of batch cnc machining parts is to select the degree of precision and roughness of parts. What should we pay attention to in CNC small batch processing? CNC processing of auto parts 1、 Over cut inspection Over cutting is a frequent problem, which should be paid special attention to. The most important review method is to make the tool path look like a mold, and repeat the inspection in the top view and side view. The tool path without review is not allowed to be machined. In profile milling, if the lower tool position is small, it will also cut too much, which can be avoided by changing the lower tool point. 2、 Die tolerance The accuracy of parts processed by CNC lathe is very strict. Only when the required accuracy is reached, can the accuracy be used. The main reason to judge the accuracy is its ability to control the size. If the accuracy is within the specified range of tolerance fluctuation, the parts are qualified. If the accuracy exceeds the tolerance, the parts are unqualified. 3、 Fixing CNC machining tools: Before the cutter head is installed on the machine, its taper fitting position should be wiped clean with a cleaning cloth. The tool length shall be adjusted by the tool tip (in special cases, the tool shall be adjusted in the middle of the tool), and the instructions in the program sheet shall be checked carefully. When the program is interrupted or the tool must be adjusted again, pay attention to whether the depth can be connected with the front. Generally, the line can be raised by 0.1mm first, and then adjusted according to the situation. If water-soluble cutting fluid is used for rotating retractable cutting head, it shall be immersed in lubricating oil for several hours every half month for maintenance. High precision automobile parts processing 4、 Arrangement of CNC processing sequence: When arranging the CNC machining sequence, the basic principles must be followed, including "face first, then hole", "rough first, then fine", etc. In addition to these basic principles, the processing should be carried out according to the centralized process of tools to avoid repeated use of the same tool and reduce the number and time of tool change. For the hole system with high coaxiality requirements, the hole system at other coordinate positions shall be processed after the whole processing of the hole system is completed after one positioning, so as to eliminate the error caused by repeated positioning and improve the coaxiality of the hole system. The tool point and tool change point shall be determined. Once determined, they shall not be replaced.

When we are processing metal parts with CNC, the surface is often scratched. What is the cause of aluminum alloy? What are the solutions? Today, Shenzhen Noble Smart Manufacturing Co., Ltd. will talk about the causes and solutions of scratches on the aluminum alloy surface. Processing of aluminum alloy parts 1、 Main causes of aluminum alloy surface damage: 1. There are sundries attached to the ingot surface or the ingot composition is low, so there will be a lot of segregation and floats on the ingot surface, which will lead to a certain amount of hard metal particles in the ingot when the ingot has never been homogenized or the homogenization treatment effect is not good. It is precisely because of these reasons that the aluminum alloy surface will be scratched; 2. Scratch caused by dragging on the swing bed; 3. Loss caused by friction or extrusion between profiles during transportation. Processing of aluminum alloy parts 2、 Solution to scratch on aluminum alloy surface: 1. Strengthen the control of ingot quality; 2. Properly place the profiles in the material frame to avoid mutual friction; 3. Handle with care during CNC processing and production to avoid dragging or turning profiles at will.

Nowadays, aluminum alloy is widely used in today's society. At the same time, CNC milling is also used. All kinds of products used by people are processed by CNC milling. In all CNC milling, aluminum alloy is the most widely used CNC machining material. Because it has many advantages, Nuobal will tell you why we choose aluminum alloy for CNC milling today. Processing of aluminum alloy parts 1、 Why do we choose aluminum profiles for CNC processing? Why did you choose it First of all, aluminum alloy itself is a light, non-magnetic silver metal, which can form metal parts of almost any shape. Aluminum is the third most abundant element in the crust, second only to oxygen and silicon. It is a relatively new industrial metal. That's why we chose it. CNC processing of aluminum alloy parts 2、 What are the advantages of CNC processing with aluminum alloy: 1. It is non-toxic, requires less heat than stainless steel or cast iron, and heats rapidly and evenly. 2. Aluminum is helpful to build buildings with corrosion resistance and low maintenance cost, and aluminum products are used for new construction and renovation. 3. The combination of light weight, strength and ductility makes aluminum CNC milling parts an ideal material for transportation applications.

The prototype model processing factory, starting from the prototype, has gradually become a project support service that can provide project support services including parts manufacturing and processing after years of experience accumulation, with up to ten years of work experience. Specializing in hand and CNC processing, plastic and metal processing, injection mold and formal mold processing. Processing of aluminum alloy parts 1、 There are three differences between CNC machining and 3D printing: Manual processing mainly includes CNC machining, 3D printing, copying, rapid tooling, etc. Today, Nuoba will tell you what is the difference between CNC machining and 3D printing. First of all, we should know that 3D printing is an additive technology, while CNC processing is a material reduction technology, so they are very different in terms of materials. CNC processing of aluminum alloy parts 1. Differences in processing materials The materials for 3D printing mainly include liquid resin, nylon powder, metal powder, etc. These three different materials occupy most of the industrial 3D printing market; The materials used for CNC machining are all sheet materials one by one, and the materials selected for CNC machining are more than those for 3D printing. General metal plastic sheets can be CNC machined, and the density of formed parts is better than that of 3D printing. 2. Different machining precision The 3D printed hand board is rough and low in accuracy; The precision of the hand board processed by CNC is high, which can generally reach ten threads. The precision of the metal hand board processed by high-speed drilling and tapping center can be reached. 3d printing model 3. Different processing ranges The 3D printing process is mainly made of plastic materials, such as photosensitive resin, ABS, etc., and its processing range is relatively limited, generally no more than 600mm. If it is larger than this size, it needs to be disassembled for printing. The cost of printing such a large prototype is also very high; The materials processed by CNC are quite extensive. It can process almost all plastics and metals, and the travel is also quite large. It is known that all of them are more than 1 meter. For example, gantry machine tools can even process the whole piece to a range of two to three meters.
