The precision machining of CNC machine parts is the basis of modern manufacturing, which directly affects the performance and reliability of the machine. How to turn design drawings into high-quality physical parts is a challenge that every manufacturing company must face. This article serves as a detailed machining manual to guide readers to understand the manufacturing process of CNC machine parts step by step from the design stage to the final product.
Physical and chemical properties of materials such as hardness, heat resistance, wear resistance and heat treatment properties are also factors that should be taken into account in CNC machining. Different material properties determine the special requirements for cutting speed, tool selection and cooling methods during processing. If you want to mechanize a part that meets the expected ideal, the first thing is to deeply understand the properties of different materials. This process is very important to optimize the CNC machining process and improve product quality. In the machining industry, different materials have their own physical and chemical properties, and they show different processing properties and applications during CNC machining.
Aluminum alloys are widely used in aerospace and automotive manufacturing due to their light weight, high thermal conductivity and good workability , while CNC machining requires cooling to prevent deformation.Stainless steel is suitable for the chemical, medical and food processing industries due to its corrosion resistance, high strength and high processing difficulty, and its wear-resistant tooling and the need for proper cooling and lubrication during processing.Brass has excellent mechanical properties and a beautiful golden appearance, which makes it suitable for decorative and conductive purposes. The CNC machining speed is not as fast as aluminum, but it is still easy to process.Alloy materials exhibit various properties depending on their composition and are suitable for certain applications, but hardness and heat treatment properties must be taken into account during processing.Plastic is very versatile, cost-effective from the general level to the engineering level, easy to CNC machining, but it should prevent thermal deformation. Then, after the material selection is completed, the necessary preliminary processes such as annealing and cleaning, which can remove the internal tension and surface impurities of the material, can be performed.
If you want to produce an ideal CNC machine part, understanding your needs and the purpose of the part is the first process. In other words, design and material selection according to our needs are the important first step in the CNC machining process. The design should not only satisfy the functionality and aesthetics, but also take into account the feasibility of processing. At the design stage, CAD/ CAM software should be used to create accurate engineering drawings based on product functionality and performance requirements to ensure that the design meets the processing and assembly accuracy requirements.
In order to design CNC machine parts, you must first understand the specific purpose of the part, such as whether it is responsible for the bearing force, the guide movement or the guarantee of accurate positioning. Then, depending on the purpose of the part and the size of the machine, the length, width, height, fillet, etc. You need to specify certain dimensions, such as. Next, we need to design the shape so that it can match well with other parts and be easy to manufacture. Finally, it is necessary to determine the performance indicators of this part, such as strength, rigidity, wear resistance and thermal stability.
Process planning is another important link in CNC machining.1According to the specifications of the designed CNC machine parts, we will establish a reasonable machining process route, including roughing, semi-finishing and finishing stages. Since different CNC machining processes are suitable for different parts, it is necessary to select the machined part according to the size, shape and material characteristics in order to process the ideal part.
CNC milling is an advanced machining technology that uses a computer to control the machine, which can produce very precise and high-quality parts. CNC milling is a multi-axis machining process. Its main advantage is the ability to move the part or tool head in multiple directions at the same time to achieve complex three-dimensional shapes. The flexibility and adaptability of this process make it an ideal choice for high-precision fields such as mold making, mechanical parts and aerospace parts.
Firstly, whether it is a special project or large-scale production, CNC milling can be applied to different production volumes. Its repeatability and speed mean that a large number of parts can be processed quickly, and costs can decrease as production increases.
In addition, CNC milling can significantly reduce the time it takes to October to receive precision machined parts from an order. Despite the high speed, accuracy can still be maintained. CNC milling can also produce parts with very high dimensional accuracy and achieve very close tolerances. This is very important for the aerospace and automotive industries.
Thirdly, as long as the correct tools and cutting speed are used, there are more than 50 kinds of engineering materials. For example, it can be CNC milling of metal, plastic, wood, glass and even stone. CNC milling can also create different shapes and functions, such as cavities, threads, bevels and grooves. Therefore, if you need to process parts with complex design and versatile machining, CNC milling is the most suitable.
However, CNC milling also has some limitations.The cost of machining complex geometries increases with the amount of material removed. During CNC milling, the part needs to be fixed, which may limit the access of the tool, resulting in the need to manually reposition the part, increasing the processing time and the possibility of errors.
Finally, there are some features that cannot be processed by CNC milling, such as curved holes, straight internal edges, and walls less than 0.5 mm thick. Although we hope that you try to avoid these features when designing, sometimes they are necessary for the function of the part. In this case, other forms of machining methods can be used.
CNC turning is primarily used to machine rotationally symmetrical parts, such as various shafts, rods, and pipes. Imagine a blade cutting into a rotating part, shaping it into the round or conical forms that we commonly see. This technology is particularly useful for manufacturing parts that require rotation, like shafts, bearing housings, and gears. Therefore, if you need precision shafts or gears, CNC turning is an excellent choice.
CNC turning technology is renowned for its high precision and efficiency. It can maintain very tight dimensional tolerances, making it highly suitable for producing components that require very high dimensional precision. In other words, nearly every detail can be replicated with exact precision. Moreover, regardless of the complexity of the shape, it can be consistently replicated in the exact same manner, ensuring that every part is identical. The technology is highly reproducible and can accurately reproduce complex shapes to ensure consistency across parts. Modern CNC lathes have multi-task machining capabilities and can perform a variety of operations such as turning, drilling, and milling. The machine can handle multiple tasks, including turning and drilling, making this technology applicable to a wide range of material types. Most importantly, its high level of automation allows for quick and efficient production, and it can produce parts with complex rotationally symmetrical shapes, such as turbine blades.
However, CNC turning does have its limitations. It is mainly suited for rotationally symmetrical part and is not ideal for machining parts with non-rotationally symmetrical shapes. If a part is designed to be rotationally symmetrical, CNC turning offers the best machining solution. For non-rotationally symmetrical parts, however, CNC milling or a CNC machining center would be a more appropriate option.
The CNC drilling process is known for its ability to accurately control the position and size of holes. It is capable of deep hole machining and is a basic step in manufacturing precision hole machining such as bolt holes and bearing holes.
The advantage of CNC drilling is that it can drill holes very accurately, ensuring that each hole is in the right position, which is very important for products that require high-precision machining. This technology also ensures that each hole is the same size and position, which is very suitable for large-scale production. Because the entire process is automated, the production speed is fast and the error rate is low. CNC drilling can also quickly adjust the settings, which is suitable for machining holes of different sizes and shapes. It can also drill multiple holes at a time, reducing the number of operation steps. Moreover, whether it is hard metal, plastic or wood, CNC drilling can handle it. Therefore, this machining process is suitable for manufacturing parts that require precise hole positions, such as bolt holes, bearing holes, etc. If you need precise hole processing in part design, CNC drilling is the first choice.
It is very important to select CNC processing technology according to the characteristics of the parts. Therefore, for selecting the appropriate CNC processing technology, we can comprehensively consider several key points.
In terms of the geometry and size of the parts, complex three-dimensional parts are suitable for CNC milling because it is more flexible to handle. For those rotationally symmetrical parts, CNC turning will be more efficient.
In terms of material, such as hardness, toughness, etc., these properties will affect the selection of cutting tools and processing speed.
The precision requirements of the parts determine the precision of the processing technology. Parts with high precision requirements may require grinding or high-precision CNC milling.
For these processing technologies, CNC turning is mainly for rotationally symmetrical shaft parts, CNC milling is suitable for parts with complex three-dimensional shapes, and CNC drilling focuses on hole processing. Each technology has its specific application field, so we can choose according to the shape, size and required processing accuracy of the parts.
First, it is necessary to select a suitable CNC machine tool according to the requirements of the processing task. This includes considering factors such as the size, accuracy, speed and price of the machine tool. For example, for tasks that require high-precision machining, you should choose a machine tool with higher accuracy. For example, we have many different types of machine tools. For example, Swiss-type lathes are very suitable for high-precision machining needs because they are good at machining high-precision parts and machining small precision parts at high speed. We also have CNC lathes. Although CNC lathes may not have the same high accuracy as Swiss-type lathes, they are also a common choice for high-precision machining, especially when machining medium-sized precision parts.
If you choose CNC milling processing technology, you can choose turn-mill composite machines, which integrate turning and milling functions. Although their main advantage is in machining complex parts, turn-mill composite machines usually also have high machining accuracy. So we have advanced CNC machining equipment, and we can choose the most suitable and efficient CNC machine tools according to the needs of the machining.
CNC machining is the process of converting designs into actual parts. The operator first converts the design drawings into G codes used by CNC machines, and then inputs them into the CNC controller through the equipment. CNC machines follow these codes to accurately remove materials and gradually form parts. When machining, you need to select the right tool, set cutting parameters, and use coolant to ensure that the machining is carried out normally. This is the entire machining process from raw materials to finished products.
In the process of manufacturing parts, CNC machines can quickly produce precise parts, but these parts usually need some additional steps after machining to ensure their quality and performance. These steps are called post-processing, and they help improve the surface of the parts, enhance their durability, and make them more suitable for specific use environments.
The first step after the procedure is to remove the burrs on the part. Burrs are small sharp pieces that are produced on the edges of parts during processing. We can grind them with tools or chemically disassemble them so that the edges of the parts are smooth and do not damage your hands or damage other items when using them.
Then, by heating and cooling the metal, it is heat treatment, which is a method of changing the properties of the metal. For example, you can harden the metal by heating it and then quickly cooling (quenching) it.
Surface treatment, such as anodizing, is a method of forming a protective layer on the metal surface, not only to prevent the metal from rusting, but also to color the metal, make the parts look more beautiful, and meet different design requirements.
In addition to the above steps, in order to reduce the tension inside the part, various methods are needed that prevent the part from deforming or breaking when subjected to force, but also control and adjust the dimensions of the part. Oct. It fully meets the design specifications and is suitable for precision assembly.
Finally, the parts are cleaned and covered with a protective layer to remove dirt and oil stains left during processing, protect the parts from corrosion and wear, and prolong their service life.
When processing CNC parts, it is an important connection after processing to ensure that the CNC machined parts meet high standards. With these steps, we can improve the surface quality, durability and applicability of components, making them more reliable and beautiful, and meet various usage requirements.
Thanks to careful design, the correct choice of processing technology, strict machine tool operation and indispensable post-processing steps, the production of CNC machine tool parts is no longer a difficult problem, and we can only be sure that the performance of each part is fully met. design standards, but also consider cost-effectiveness and efficiency aesthetic with the development of technology, while achieving functionality, the processing of CNC machine tool parts is becoming increasingly intelligent and automated The application of CNC machine tool parts will become more and more comprehensive, opening a new chapter of endless possibilities to different industries.
