All kinds of raw materials, that is, all kinds of metal resources, use different machine tools or machines or be processed according to the requirements to make various parts with different performance and different types, that is, hardware processing. In life, there are too many products will carry out different functions of the operation, but in the process of parts operation, for the hardware processing are will have a certain function index, also will get different function test process. Hardware processing will also have a different development status.

Therefore, in the operation process of different functions, different hardware processing products will be used, and the operation trend of various processes will be carried out. The use of hardware processing will get different process realization, but in the operation process of different processing technology, it will also get more steps of operability, and will be assigned to the control, and will also get the use of appropriate processing technology. Among them, in the process of carrying out different processing processes, they will be based on different processing steps to get the appropriate engineering processing process.

But in the development process of hardware processing, will be based on different control process, to get the appropriate engineering processing trend, for the hardware processing enterprises, are will carry out different economic control process, ensure that all kinds of processing industry will get different process realization, also will get different control trend, among which in the enterprise In the development trend, will also be in accordance with the better development status quo, for the development trend of the enterprise, to carry out more process realization. Therefore, it is not only the need to carry out the reform of the economic system, for the institutionalization of hardware processing innovation process, there will be different trends

In fact, the metal processing is in accordance with the specified process to achieve, but in the process of different types of metal processing, will ensure the development of different operations. Then in the trend of ensuring the appropriate steps, more technical and functional implementation will be obtained. Therefore, in the process of getting more metal precision, it will also ensure the realization trend of more functionality. The development of precision hardware processing, will be based on the actual use of metal resources to get more technical innovation trend.

So in the process of processing different metal resources, we will control the process according to the actual ability to ensure the rational use of resources. In the control process of ensuring more processing technology, the implementation of better steps will be obtained. In the process of precision hardware processing, new changes and process utilization will be carried out for the modern processing trend. In the process of ensuring the processing steps, different performance will be obtained to carry out better ability control process. Among them, in the process of specified ability control, there will be the realization of new capabilities.

Among them, in the process of different utilization of metal, the society will carry out more metal utilization, to carry out the operation process of more metal products and equipment, among which, in the process of using more capabilities, all will have the control trend of appropriate functions, so in the process of using different properties, it will ensure that more and more metal products and equipment will be used More metal utilization process, then in the implementation process of the appropriate process, will ensure the actual ability of the utilization process. If you have more interest in precision hardware processing,

With the rapid development of the processing industry, some of our processing industries are also in continuous development. The precision hardware processing is the same, and the development is still very good. What are its advantages and why is it so popular?

1. CNC machining precision of precision hardware shaft is high, with stable processing quality;
2. It can carry out multi coordinate linkage and process complex shape parts;
3. When the CNC machining parts of precision hardware are changed, only the NC program needs to be changed, which can save the production preparation time;

Tangxia precision hardware processing

1. The machine tool itself has high precision and rigidity, so it can choose favorable processing amount and high productivity (generally 3 to 5 times of ordinary machine tool);
2. High degree of automation of machine tools can reduce labor intensity;

For the quality of processing, it depends on what factors, including many, may be the processing method, may also depend on the material, these are possible, automatic parts processing is the same, then the quality of automatic parts processing depends on what reason?

The quality of the machine depends on the processing quality of the parts and the assembly quality of the machine. The machining quality of the parts includes the machining accuracy and the surface quality of the parts. The machining accuracy refers to the degree to which the actual geometric parameters of the parts are consistent with the ideal geometric parameters. The difference between them is called machining error. The size of machining error reflects the level of machining accuracy. The larger the error is, the lower the machining accuracy is, the smaller the error is, the higher the machining accuracy is; the main factors affecting the machining accuracy are: dimensional accuracy, the conformity between the actual size of the part after processing and the tolerance zone center of the part size.

The machining error of Automatic Parts reflects the machining accuracy. The larger the error is, the lower the machining accuracy is, the smaller the error is, the higher the machining accuracy is; the main factors affecting the machining accuracy are: dimensional accuracy, the conformity between the actual size of the part after processing and the tolerance zone center of the part size. Compared with the method of producing parts with die casting die, it avoids the uneconomical of opening the die when manufacturing small batch parts, and shortens the production cycle greatly. At the same time, the correct clamping and positioning and reasonable processing technology make the processed parts have high precision and surface finish, which is not achieved by die casting process. Moreover, the density of extruded aluminum profile is higher than that of die casting. In addition, this method is different from the general single part machining production, it can batch produce a bed of parts. If the working table of the machine tool is large enough, the bottom plate can be made larger, and several aluminum materials can be arranged at a time, then the processing efficiency can be further improved and the number of tool changes is relatively reduced. If there are features on the side of the part to be processed, such as a round hole to be drilled, then after the part is cut off on the B side, the fixture shall be manufactured, and the part shall be installed

Hardware equipment, or the application of hardware processing machine tools, in today’s machinery industry, or silicone, or mold, steel, electronic products, other products, after the processing of mechanical equipment, the effect and efficiency are much faster, and reduce the processing pressure of employees. Now hardware manufacturers include a wide range, such as keys, or some metal plates, or etching, or other materials, iron.

1. Spray painting: spray painting is widely used in some relatively large hardware parts. The existence of spray painting can not only make the products not easy to rust, but also produce some other effects, so that the performance of the products is better. It is a step that many hardware parts processing manufacturers will carry out when processing finished products.
2. Electroplating: electroplating is a relatively common hardware parts processing technology, because the use of this process for the product surface rust resistance performance is very good, can let the product in a long period of time can be normal and stable work, and is widely used in the current hardware products processing.

1. Polishing: polishing is often used in some daily necessities of hardware parts processing technology. Polishing is not only to maintain the appearance of products, but also to make users feel better. Especially for some products which are easy to balloon and burr, polishing is a necessary step. Now China’s hardware industry is developing rapidly, and the continuous development of science and technology is also constantly promoting the improvement of hardware processing technology. I believe that there will be more processing technology to be created in the future, which will bring convenience to human production.

First of all, the most important error of secondary positioning and non coincidence is the error of non coincidence. When machining the workpiece on the machine tool, it is necessary to select some geometric elements on the workpiece as the positioning datum during processing. If the selected positioning datum does not coincide with the planning datum, the datum misalignment error will occur. Measurement error: when measuring parts during or after processing, the measurement method, measuring tool precision, workpiece and subjective and objective factors directly affect the measurement accuracy. There are fixture errors and tool errors: mechanical fixture errors: the role of the fixture is to make the workpiece equivalent to the tool and machine tool with the correct orientation, so the geometric errors of the fixture have a great impact on the machining errors. Spindle rotation error refers to the variation of the actual rotation axis of the spindle relative to its uniform rotation axis at each moment, which will directly affect the accurate density of the workpiece. Any tool in the cutting process can not prevent wear, and thus cause the size and shape of the workpiece to change.

The structure and shape of machine parts are composed of some basic geometric surfaces. The machining process of machine parts is the process of obtaining these geometric surfaces. Different processing methods can be selected for the same surface, but the processing quality, processing time and cost obtained by each processing method are different. The task of engineering and technical personnel is to select the most appropriate processing method according to the specific processing conditions, so as to ensure that the machine parts meeting the requirements of the drawings can be processed. When selecting the processing method, the final processing method is always selected first according to the technical requirements of the main surface of the part and the specific conditions of the factory, and then the processing methods of the relevant previous processes of the surface are selected one by one. The machining surface of parts has certain processing requirements. Generally, it is impossible to achieve the requirements through one processing, but it can be achieved gradually through multiple processing (i.e. multiple processes).

Arrangement of heat treatment process and surface treatment process!

The heat treatment processes arranged to improve the cutting performance of workpiece materials, such as annealing, normalizing, quenching and tempering, should be carried out before cutting.

In order to eliminate the internal stress of the workpiece, the heat treatment process, such as artificial aging and annealing, should be arranged after the rough machining stage.

In order to improve the mechanical properties of workpiece materials, heat treatment processes, such as quenching, carburizing and quenching, are generally arranged between semi finishing and finishing.

In order to improve the wear resistance and corrosion resistance of the workpiece surface, the heat treatment process arranged for the purpose of decoration, such as chromium plating, zinc plating, blue plating, etc., are generally arranged in the final stage of the process.

The processing of metal equipment is not only the quality required by customers, but also the needs of the times. Why do you say that? The general quality is not guaranteed. Do you think that anyone else will buy your products? In the long run, your manufacturers will lose money. If we continue to develop in this way, we will not even get the cost. Therefore, it is Zui to guarantee the customer’s return purchase rate in the early stage of hardware processing important.

How about the hardware processing market

Since entering the 21st century, China is gradually becoming an international hardware processing and exporting country, with huge market and consumption potential. China’s self-developed various kinds of daily hardware products rank in the forefront of the world, and have achieved good economic benefits and reputation. The development of hardware processing market has thousands of years of history, with the continuous evolution of society, its development is also changing with each passing day. All kinds of advanced products are inseparable from the design and development of hardware, and these just confirm the changes of social development.

How about the hardware processing market

With the deepening of competition, the profit space of metal stamping industry chain in each stage is compressed, and the space of price reduction is decreasing day by day. More and more enterprises realize that only relying on price competition can not establish the core competitiveness and is not the direction of long-term development, so they try to explore a new development path. Many hardware enterprises have increased their investment in technology, developed new products with high-tech content, took product differentiation as a long-term plan for enterprise development, sought new market demand, established new economic growth point, and realized sustainable development of enterprises. The next few years will be a period of high-speed shock in the metal stamping industry. The direct consequence of this high-speed shock is the expansion of the polarization trend of the current metal stamping industry. It is expected that in the next few years, there are not so many metal stamping enterprises that can survive in the market. But the high-speed shock of the metal stamping industry will bring great opportunities, and the result of the shock will make the market operation more rational.

Metal parts processing, most of the use of mechanical equipment to complete the work, the effect is good, and the processing speed is fast, in a certain range involved is also relatively wide, the era is changing, we need to apply the mechanical equipment is also increasing, different industries, then the types of mechanical equipment, or classification, model are different, precisely because with the times Change, machining precision, requirements are higher and higher. So we must pay attention to the craftsmanship! What are the skills of turning simple shaft in machining knowledge?

What is the axial datum in machining knowledge?

Compared with shaft, the expression scheme of sleeve is roughly the same as that of shaft. Generally, only one basic view and a small number of auxiliary views are needed. Only because the sleeve is hollow structure, it is necessary to carry out sectional representation (whether to use full section, half section or partial section depends on the complexity of the internal and external structure shape of the part). The dimension datum only has radial datum and axial datum. The axial datum should be the axial positioning surface when the sleeve is fitted to other parts, that is, the right end face of the left-hand 040 cylinder. The surface roughness requirement is such as the ring plane with Gen value of 0.8.

What is the method of threading in machining common sense?

If the diameter of the round rod is too large, it is difficult to insert the die and the thread is not complete if it is too small. The diameter of round rod can be calculated by consulting the manual or empirical formula: the diameter of round rod is 4 = (nominal diameter of thread) – 0.13p (pitch). The end of round rod with thread set shall be chamfered (15 ° ~ 20 °), and the diameter of small end of round rod after chamfering shall be less than the minor diameter of thread, so as to facilitate thread setting. The process of threading is similar to tapping. When threading, the die end face should be strictly vertical to the round rod. When starting to rotate the die, a little pressure should be evenly applied; after 3-4 turns of threading, the die can only be rotated without pressure. In the process of thread setting, it is necessary to reverse frequently for chip breaking. The thread of steel parts should be lubricated with oil.

Metal parts, parts processing, is now very common, mainly related to our development, the better, the faster the development, the more research and development of mechanical equipment, the effect is better, the role is obvious, automation era, hardware accessories in a wide range, market development in recent years, however, hardware processing need to pay attention to the details Many, for example?
