Aluminum alloy precision parts processing characteristics and advantages of industry solutions

CNC machining of aluminum alloys is a mechanical processing method that uses CNC machine tools to process parts and digital information to control the displacement of parts and tools.

Aluminum alloy precision parts machining is a highly specified CNC machining method; its relative traditional CNC machining methods can achieve better results; as we all know, aluminum alloy machining precision is usually at a greater level to determine the quality of the processed parts; it is not difficult to find that more and more companies are choosing CNC machining of aluminum alloy precision parts, and where are the advantages of its performance?

I. CNC machining characteristics of aluminum alloy

1. Aluminum alloy hardness is low: compared with other metal materials, aluminum alloy has a low hardness, so cutting performance is good, but at the same time, this material is also due to the low melting point, the characteristics of the flexibility of the large, very easy to melt in the finishing surface or tool on the adherence, but also very easy to produce burrs and other shortcomings. Heat-treated or die-cast aluminum alloys also have high hardness. The general HRC hardness of aluminum plate is below 40 degrees, which is not a high-hardness material. Therefore, in the cnc aluminum parts machining process, the machining tool load will be small. In addition, the thermal conductivity of aluminum alloy is excellent, and the temperature required to cut aluminum parts is low, which can significantly improve the milling speed.

2. Aluminum alloy has low plasticity. Plasticity is the ability of a material to deform and extend its deformation under constantly applied external force during processing and deformation. The plasticity of an aluminum alloy mainly manifests in its high elongation and low resilience. That is, it can deform plastically under the action of external force and maintain a certain degree of deformation.

The grain size usually influences the "plasticity" of aluminum alloys. Grain size is the critical factor affecting the plasticity of aluminum alloys. Generally speaking, the finer the grain size, the better the plasticity of the aluminum alloy. This is because the finer the grain size, the greater the number of dislocations created during the processing of the material, the easier it is to deform the material, and the higher the degree of plasticity.

Aluminum alloys have low plasticity and low melting points. cnc aluminum machining has poor chip removal and high surface roughness. This requires CNC machining factories to solve the two problems of aluminum alloy machining: the fixed knife edge and machining surface quality.

3. In aluminum machining, the tool is straightforward to wear. In the aluminum machining process, due to unsuitable tools in the bar edge, cutting discharge problems under the multiple influences of the tool's wear will be more serious. Therefore, before machining aluminum parts, you should select a tool that can minimize the cutting temperature, has a good roughness of the front face, and can also discharge the cut smoothly—the most suitable tool with a phase cutting edge and enough space for chip evacuation.

II. Aluminum alloy precision parts processing advantages

First of all, according to Noble Platinum editors, over the years of CNC machining experience, the appearance of aluminum alloy parts full of unique metal texture, lightweight, and heat dissipation is strong and favored by various industries. Aluminum alloy precision parts CNC machining advantages are as follows:

1. Multi-axis manipulation linkage: In general, there is a three-axis linkage with more, but some adjustments can ensure four-axis, five-axis, seven-axis, and even a large number of linked axes of the machining center.

2. Machine and connect: The role of universal CNC machining centers is also more fixed. They can be machining centers and milling cores or column and vertical machining centers together, enhancing the machining center processing scope and processing capacity.

3. Tool damage warning information: Some technical inspection methods can help you deal with tool damage promptly, destroy the situation, and carry out the alarm so that you can ensure the immediate replacement of the tool to ensure the quality of parts processing.

4. Tool life management methods: There can be more than one with the same working tool and the same tool on several heads to carry out unified management methods to improve productivity.

5. Machine load-off power maintenance: Set a higher load level according to the production process's load. When the load achieves the rated value, the machine can be completed automatically shut down the power standby to maintain its efficiency.

III. Aluminum alloy precision parts processing industry characteristics of the solution

As we all know, aluminum alloy precision spare parts have high strength, good plasticity, excellent electrical conductivity, thermal conductivity, and corrosion resistance. They can be heat treated to obtain good mechanical properties, physical properties, and corrosion resistance. Aluminum alloy spare parts are processed by lathe and CNC computer and sandblasted, polished, brushed, plated, sprayed, anodized, laser engraved, and subsequent processing according to the need. Why are aluminum alloy precision parts increasingly widely used in various fields?

1. Aluminum alloy precision parts are processable.

Aluminum can be easily formed, processed, and machined through various processes. Because it is soft and easily broken, it can be cut quickly and easily with machine tools. It is also cheaper and requires less electricity than steel. These features benefit machinists and customers ordering parts. In addition, aluminum's good machinability means it deforms less during machining. This leads to higher precision, allowing CNC machines to achieve higher tolerances.

2. Aluminum alloys are solid

Aluminum parts have a high strength-to-weight ratio. The density of aluminum is about one-third that of steel. The demand for aluminum parts has increased. The material is solid but lightweight. These two properties make it ideal for manufacturing critical components in the automotive and aerospace industries.

However, different grades of aluminum have other uses. With an excellent strength-to-weight ratio, general-purpose products such as 6061 can be used for a wide range of parts, and it is worth noting that high-strength products such as 7075 may be preferred for aerospace and marine applications.

3. Aluminum Alloys with High Corrosion Resistance

Aluminum is resistant to scratching and corrosion in common marine and atmospheric conditions. Anodizing can enhance these properties. However, the corrosion resistance of different grades of aluminum varies. For example, grades 6061 and 7475 have excellent corrosion resistance.

4. Aluminum alloys can withstand temperature changes

Steel and aluminum have been popular for several years. These metals have unique advantages that make them ideal for various industrial applications. Steel is the most popular of the two materials in terms of durability. However, steel is not the right choice regarding temperature changes. For example, steel cannot withstand high or extremely low welding temperatures. Aluminum, however, can effectively withstand both. Aluminum retains its flexibility, elasticity, and strength at extremely low temperatures.

5. High electrical conductivity of aluminum alloys

Pure aluminum has an electrical conductivity of approximately 37.7 million Siemens per meter at room temperature. Although aluminum alloys may have a lower electrical conductivity than pure aluminum, they are conductive enough to find uses for their parts in electrical components. On the other hand, aluminum would be an inappropriate material if electrical conductivity is not desirable for machined parts.

6. Aluminum Alloys are Recyclable

Aluminum parts are easily recyclable, which helps increase their use in industrial applications. As a result, CNC-machined aluminum parts are ideal for companies looking to reduce their carbon footprint. CNC machining is a subtractive process in which a large amount of material waste is generated due to a swarf.

Material waste can be recycled to produce better products.

7. Anodizing

The anodizing process is usually performed after machining is complete. It consists of passing an electric current through the part in an electrolytic acid bath, which is easily achieved in aluminum. This produces aluminum pieces that are more resistant to physical impact and corrosion.

8. Aluminum alloys are customizable

It is well known that aluminum alloys can be easily customized to meet customer needs. CNC-machined parts can be embellished or trimmed to the desired specifications. For example, we can plate aluminum alloys with green, black, blue, or any other desired colors and after-appearances, including oxidation.

Aluminum alloys are used as CNC machining materials because of their machinability, high strength, and corrosion resistance. They provide one-stop CNC machining services, ensuring the precision and quality of aluminum alloy parts machining.

IV. Aluminum processing solutions

1. Hot processing: This is a kind of feed aluminum alloy ingot billet in the recrystallization temperature above the completion of the plastic forming process; hot processing, ingot billet plasticity is higher and lower deformation resistance, can be used to produce the deformation of a smaller capacity of the equipment more oversized products.

2. Cold working refers to the plastic forming process completed below the temperature that does not produce a return and recrystallization. The essence of cold working combines cold working and the intermediate annealing process. Cold working can be to the surface clean, precise size, organization, and performance to meet the different performance requirements of the final product.

3. Warm processing: Warm processing is a plastic molding process between cold and hot processing. Temperature processing mainly aims to reduce the metal's deformation resistance and improve its plastic properties.

V. Aluminum CNC machining considerations

1. Aluminum profile temperature setting and control: generally, the temperature and the apparent temperature have a specific error set. The table temperature should be set according to the actual temperature of the equipment, and pay close attention to temperature fluctuations

2. Aluminum profile aging and heat preservation: the aging should be set in strict accordance with the processing technology requirements, and the heat preservation time should be appropriate to prevent insufficient hardness due to insufficient aging or too long aging.

3. Aluminum extrusion frame can not be too dense: materials and materials to have a gap between the aluminum profile, especially not ventilated small material, the thick material gap needs to be greater, tube material, trim material, and plate material combined in a frame, tube material put below the conducive to aging cycle air supply. It achieves higher strength and hardness. After die-casting, machining, annealing, and many other processes, aluminum alloy parts are not uniform because of their grain size and distribution, resulting in insufficient mechanical properties and tensile strength. "Aging" treatment is after these processes, the material will be heated to a specific temperature again and kept for a certain period to make the grains in the material rearrange and form a uniform structure to improve the hardness and strength of the material.
