Precision machinery parts processing plays a crucial role in various industries, including aerospace, automotive, medical, and manufacturing.Precision machinery parts have specific requirements to ensure optimal performance.One crucial aspect is the material used for processing. If the hardness of the material being processed surpasses that of the lathe tool, it can potentially cause irreparable damage.Therefore, it is essential to select materials that are compatible with precision machining.
1. Material Strength and Durability
One of the key requirements of precision machinery parts processing is material strength and durability.Machinery parts often undergo significant stress and pressure during operation, and the selected materials must be able to withstand these forces without deforming or breaking.For example, aerospace components require materials with high strength-to-weight ratios, such as titanium alloys, to ensure structural integrity and reliability.
2. Dimensional Stability
Precision machinery parts must maintain their dimensional stability even under extreme operating conditions.The materials used in their processing should possess low thermal expansion coefficients, allowing the parts to retain their shape and size without warping or distorting due to temperature fluctuations.Steels with low thermal expansion coefficients, such as tool steel or stainless steel, are commonly preferred for precision machinery parts subjected to varying thermal conditions.
3.Wear and Corrosion Resistance
Precision machinery parts often interact with other components or environments that can cause wear and corrosion.The materials chosen for their processing should exhibit excellent wear resistance to withstand constant friction and minimize surface damage.Additionally, corrosion resistance is crucial to ensure the longevity of the parts, especially in industries where exposure to moisture, chemicals, or harsh environments is common.Materials such as hardened steel, stainless steel, or certain grades of aluminum alloys are frequently utilized to enhance wear and corrosion resistance.
4.Machinability
Efficient and precise machining is a critical factor in the manufacturing of precision machinery parts.The material selected for processing should possess good machinability, allowing it to be easily cut, drilled, or shaped into the desired form with minimal tool wear.Materials like aluminum alloys with excellent machinability properties are often preferred for their versatility and ease of shaping into complex geometries.
5.Thermal Conductivity
Thermal management is significant in precision machinery parts processing, as excessive heat can adversely affect performance and increase the risk of failure.Materials with high thermal conductivity, such as copper alloys or certain grades of aluminum, help dissipate heat efficiently, preventing localized temperature rise and ensuring optimal operating conditions.
6.Cost-Effectiveness
While meeting the specific requirements is crucial, cost-effectiveness is also an important consideration in precision machinery parts processing.The selected materials should strike a balance between performance and cost, ensuring that the final product remains economically viable without compromising quality.Conducting a cost-benefit analysis and considering factors like material availability, processing complexity, and overall project budget can aid in making informed decisions regarding material selection.
Precision parts processed with stainless steel have the advantages of corrosion resistance, long service life and good mechanical and dimensional stability, and austenitic stainless steel precision parts have been widely used in medical, instrumentation and other precision machinery fields.
The reasons why stainless steel material affects the machining accuracy of parts
The exceptional strength of stainless steel, coupled with its impressive plasticity and noticeable work hardening phenomenon, result in a significant disparity in cutting force when compared to carbon steel. In fact, the cutting force required for stainless steel surpasses that of carbon steel by more than 25%.
At the same time, the thermal conductivity of stainless steel is only one-third of that of carbon steel, and the cutting process temperature is high, which makes the milling process deteriorate.
The growing machining hardening trend observed in stainless steel materials demands our serious attention. During milling, the intermittent cutting process leads to excessive impact and vibration, resulting in substantial wear and collapse of the milling cutter. Furthermore, the use of small-diameter end milling cutters poses a higher risk of breakage. Significantly, the decrease in tool durability during the milling process adversely affects the surface roughness and dimensional accuracy of precision parts machined from stainless steel materials, rendering them unable to meet the required standards.
Stainless steel precision parts processing precision solutions
In the past, traditional machine tools had limited success in machining stainless steel parts, particularly when it came to small precision components. This posed a major challenge for manufacturers. However, the emergence of CNC machining technology has revolutionized the machining process. With the aid of advanced ceramic and alloy coating tools, CNC machining has successfully taken on the complex task of processing numerous stainless steel precision parts. This breakthrough has not only improved the machining accuracy of stainless steel components but has also significantly enhanced the efficiency of the process. As a result, manufacturers can now rely on CNC machining to achieve precise and efficient production of stainless steel precision parts.

3D printing has been applied since the 1980s, just over 30 years, 3D printing this emerging technology has been applied to a number of industries. With the improvement of people's demand for personalized and customized automotive products, as well as the difficulties such as the long time and high cost of manufacturing and maintenance of some traditional complex process parts, 3D printing technology is increasingly favored by auto companies, parts and after-sales service suppliers. As we all know, the automobile industry is a typical capital and technology-intensive industry, and the investment in new car research and development is also very large. As a result, car companies, parts and after-sales service suppliers are actively exploring new technologies to reduce material costs and improve efficiency. 3D printing technology then began to explore and apply in the field of automotive parts, especially in automobile manufacturing and maintenance has become more and more mature.
3D printing technology
Definition of 3D printing technology
3D printing technology is a kind of digital model file based on the use of powder metal or plastic and other adhesive materials, through the 3D printer, layer by layer to construct the object technology. This technology allows us to convert digital models into physical objects through CAD (computer Aided design) software. Applications of 3D printing technology include manufacturing, medical fields and so on.
The advantages of 3D printing technology
1. Rapid Prototyping: 3D printers offer rapid prototyping, allowing you to quickly design, produce, and test custom parts, and quickly modify designs without affecting the speed of the printing process.
2. Design freedom: 3D printing allows you to make complex geometric shapes that are difficult to make with traditional manufacturing methods. You can easily modify the design and make any type of geometry.
3. Reduce waste: 3D printing uses an additive manufacturing process, where the only materials used are those needed to produce the required parts. Traditional processing methods cut large chunks of non-recyclable material to produce parts, resulting in a lot of waste.
4. Cost: Due to the reduction of material waste, 3D printing reduces production costs because you only pay for the materials you need to print.
5. Print on demand: 3D printing allows you to print on demand, avoiding inventory overhangs and costly inventory. It uses just-in-time inventory management technology to free up inventory space by printing designs in the exact amount needed only when needed.
6. Speed: 3D printing can print parts in as little as a few hours, depending on the complexity and part size, while processing can take much longer.
7. Provide more manufacturing options: 3D printing methods offer a wide range of manufactured products. It can produce individually designed and customized products.
8. Lighter: Plastic materials used in 3D printing are much lighter than metal. Many cars use 3D printed parts to make their vehicles lighter and more fuel efficient.
9. Save on warehousing costs: 3D printing only produces products on demand, so you don't have to worry about storage space or warehouses with excess stock.
10. Create more jobs: The widespread use of 3D printing will create jobs for engineers to design equipment and technicians who will maintain inventory and solve problems. More artists will rely on the use of 3D printing to deliver their products.
Disadvantages of 3D printing technology
1. Not suitable for mass production: If a large number of parts need to be produced, then 3D printing is not an ideal production process. Other methods, such as injection molding, may be cost-effective for printing large parts.
2. Limited materials: Only specific plastics with certain mechanical properties can be used to produce 3D printed parts. Some 3D printers can use metal, and metal options are limited.
3. Limited build volume: Most 3D printers have small build rooms, and if your printed parts are larger than the build printer room, you'll have to split those parts into multiple parts and glue them together during post-processing.
4. Large print costs increase: If your print is larger than the build room, the cost of printing will increase because the print will take longer. The process also requires manual labor.
5. Fewer manufacturing jobs: 3D printing will lead to fewer manufacturing jobs, which will have an impact on third world economies, especially those that rely on low-skilled jobs.
6. Copyright issues: Increased use of 3D printing mechanisms can lead to a lot of copyright issues. It will open the door to more counterfeit products, especially if the products exist in digital files.
7. Post-processing: 3D printing needs to be cleaned to remove supporting materials and make the surface of the produced parts smooth. This slows down the process.
8. Manufacture of dangerous goods: Without proper regulation, 3D printing can lead to the manufacture of dangerous goods such as guns and counterfeit money. The production process can also undermine control mechanisms.
9. Printing useless items: 3D printing can lead to the manufacture of environmentally unfriendly useless items.
10. Part structure: In the additive manufacturing process, parts are printed in layers and must be bonded to each other during the printing process. If the layers separate, the part will break.
/ what are the applications of 3D printing in the automotive industry?
01. Make vehicle spare parts
Because the car will be damaged and need to be repaired, 4S shops and auto repair shops will prepare some parts. However, because there are too many car parts, it is impossible to reserve every part, and inventory costs will be high. The small market with few manufacturers also leads to prolonged maintenance time.
Therefore, 3D printing parts has become a new way of spare parts, and the store can print the required parts directly in the store, which makes it possible to reduce inventory pressure and reduce maintenance time.
On the one hand, it reduces the inventory pressure, and on the other hand, it saves the time of ordering parts and improves the maintenance efficiency.
In the future, parts warehouses are likely to be dominated by digital models.
02. Make product samples
Automobile as a comprehensive product of modern industrial civilization, from design to mass production, research and development during the need to produce a large number of samples. Before 3D printing, these samples were processed by hand, CNC and other methods.
At present, in the development stage, there are already a large number of samples are produced by 3D printing. With the advancement of 3D printing technology, the advantages of short production cycle, high precision and low cost will be further highlighted.
03. Mass production of parts
At present, 3D printed parts are still relatively few directly applied to mass production vehicles, and most of them are still used as test parts.
It is not that the quality of 3D printed parts is not good, but the current 3D printing speed can not meet the needs of mass production.
Therefore, the current 3D printed parts are only used in some relatively small production models, such as various supercars, F1 cars, and as modified parts.
Due to the high degree of customization and small molding limitations of 3D printing, some topologically optimized parts can be manufactured, which often have complex geometry, lighter and better performance than the original parts.
At present, the top manufacturers in the automotive industry are increasing their investment in the research and development of 3D printing technology. It is hoped that 3D printing technology can be used to mass produce parts and bring better performance to cars.
04. Realize distributed production mode
As we all know, the automotive industry is a highly concentrated industry, a large number of parts are shipped to factories, assembled on the production line into complete vehicles, and then shipped around the world for sale.
The transportation involved takes a lot of time and money. For example, the new French car Citroen is concentrated in Chengdu production, and then sent to global sales.
3D printing can realize distributed production, and the chassis and various parts can be 3D printed locally and then assembled.
05. Print the whole car
From the current point of view, the printed vehicle is still a certain distance from mass production, but over the years, a variety of 3D printed cars and electric vehicles are also a lot.
The current 3D printing technology can already be used to print the whole vehicle chassis, frame, door, etc., and the 3D printed chassis and other parts can be integrated with multiple parts and printed in one, which can not only reduce the assembly time, but also improve the firmness.
However, it is currently limited by the printing speed and does not have the capacity for mass production. When the printing speed increases to a certain stage, 3D printing production cars are not impossible.
From these perspectives, when 3D printing technology is developed to a certain extent, the future impact on the automotive industry will be enormous.

Brand of moisture meter: Boshi Model: bos-180a series Test item: automotive plastic sheet
The water content of plastics is a key reason affecting the production process, commodity appearance and commodity characteristics of resin materials such as polyethylene (PE) and polypropylene (PP). In the injection molding process, if the plastic raw materials with excessive water content are used for production and manufacturing, it will cause some production and processing problems and affect the product quality, such as cracking of the surface layer, reflection, wear resistance, reduction of material mechanical properties such as service performance and tensile strength, etc. Therefore, the control of water content is particularly important for the production of high-quality plastic products.
Testing water content is a necessary step in the production of plastic materials. Testing moisture content is basically divided into national standard method and rapid moisture tester method. Boshi plastic rapid moisture tester is a widely used instrument and equipment at present.(auto plastic parts)Test steps:
1. First, take out the moisture meter, place it and power it on, then break the test material into small pieces, pour out about 6 grams of plastic pieces and pour them into the stainless steel tray. In order to dry and dry the plastic thoroughly during the test, we spread the fine pieces of plastic parts into a scattered form so that the temperature can penetrate into the plastic parts. Use tweezers to lay small pieces of plastic parts evenly. In order to avoid the zoom and blackening of small pieces of plastic parts after baking, we set the temperature at 105 , press the "start" key to start the test for 1 minute and 49 seconds, and then the test ends, and the test data displays 0.3%;
2. In order to obtain more stable data results, wait for the moisture meter of plastic parts to cool down before the second test. When the temperature of the instrument itself drops below 40 , also take about 6 grams of small pieces of plastic parts into the stainless steel tray, and lay the small pieces of plastic parts evenly. This time, we set the temperature at 105 , press the "start" key to start the test, and the test ends after 1 minute and 38 seconds, The test data showed 0.29%;Test data:From the above tests, we found that the moisture of these plastic sheets was well controlled and the moisture distribution was relatively uniform, which promoted the plastic parts to be completely dry after the test, and the moisture data results were also very good.
matters needing attention:1. Small pieces of plastic sheets shall be small enough to ensure the complete drying of water in plastic parts, and shall be evenly spread on the tray as far as possible, rather than simply stacked together.2. Do not set the temperature too high to prevent the plastic parts from melting in case of high temperature. The moisture meter of plastic parts has its use environmental restrictions. Please use it under the environmental conditions specified in the product operation manual. Do not operate in harsh environments.
3. As the instrument is a precision instrument, do not knock the workbench or vibrate the instrument during heating, otherwise the measurement will be inaccurate.4. After the test, do not touch the tray for the Yi first time to avoid scalding.Editing: JQ
