How to choose the right CNC machining material？
The materials are wrong, all in vain! In order to produce satisfactory products, the choice of materials is the most basic step and the most critical step. CNC machining can choose a lot of materials, including metal materials, non-metallic materials and composite materials.
Common metal materials include steel, aluminum alloy, copper alloy, stainless steel and so on. Non-metallic materials are engineering plastics, nylon, bakelite, epoxy resin and so on. Composite materials are fiber reinforced plastic, carbon fiber reinforced epoxy resin, glass fiber reinforced aluminum and so on.
Different materials have different physical and mechanical properties, and the correct selection of the right material is critical to the performance, accuracy and durability of the part. Starting from my own experience, this article will share with you how to choose low cost and suitable materials among many processing materials.
First, we need to determine the end use of the product and its parts. For example, medical equipment needs to be disinfected, lunch boxes need to be heated in the microwave oven, bearings, gears, etc., need to be used for load-bearing and multiple rotational friction.
After determining the use, starting from the actual application needs of the product, the use of the product is investigated, and its technical requirements and environmental requirements are analyzed, and these needs are transformed into the characteristics of the material. For example, parts of medical equipment may have to withstand the extreme heat of an autoclave; Bearings, gears and other materials have requirements for wear resistance, tensile strength and compressive strength. Mainly can be analyzed from the following points:
01 Environmental Requirements
Analyze the actual use scenario and environment of the product; For example: What is the long-term working temperature of the product, the highest/lowest working temperature, respectively, belonging to high temperature or low temperature? Are there UV protection requirements indoors or outdoors? Is it in a dry environment or a humid, corrosive environment? Etc.
02 Technical Requirements
According to the technical requirements of the product, the required capabilities are analyzed, which can cover a range of application-related factors. Such as: the product needs to have conductive, insulating or anti-static which of the capabilities? Is heat dissipation, thermal conductivity, or flame retardant required? Do you need exposure to chemical solvents? Etc.
03 Physical Performance requirements
Analyze the required physical properties of the part based on the intended use of the product and the environment in which it will be used. For parts subjected to high stress or wear, factors such as strength, toughness and wear resistance are critical; For parts exposed to high temperatures for a long time, good thermal stability is required.
04 Appearance and surface treatment requirements
The market acceptance of the product depends largely on the appearance, the color and transparency of different materials are different, the finish and the corresponding surface treatment are also different. Therefore, according to the aesthetic requirements of the product, the processing materials should be selected.
05 Processing performance considerations
The machining properties of the material will affect the manufacturing process and accuracy of the part. For example, although stainless steel is rust resistant and corrosion resistant, its hardness is high, and it is easy to wear the tool during processing, resulting in very high processing costs, and it is not a good material to process. The plastic hardness is low, but it is easy to soften and deform during the heating process, and the stability is poor, which needs to be selected according to actual needs.
Because the actual application requirements of the product are composed of a number of contents, there may be multiple materials that meet the application requirements of a product; Or the situation where the optimal selection of different application requirements corresponds to different materials; We may end up with several materials that meet our specific requirements. Therefore, once the desired material properties are clearly defined, the remaining selection step is to search for the material that best matches those properties.
The selection of candidate materials begins with a review of material properties data, of course, it is not possible to investigate thousands of applied materials, and there is no need to do so. We can start from the material category, and first decide whether we need metal materials, non-metallic materials or composite materials. Then the previous analysis results, corresponding to the material characteristics, narrow the selection of candidate materials. Finally, the material cost information is used to select the most suitable material for the product from a number of candidate materials.
At present, Honscn has selected and launched a number of materials suitable for processing, which have been a popular choice for our customers.
Introduction to the properties of metal materials
Metallic materials refer to materials with properties such as luster, ductility, easy conduction and heat transfer. Its performance is mainly divided into four aspects, namely: mechanical properties, chemical properties, physical properties, process properties. These properties determine the scope of application of the material and the rationality of the application, which is an important reference for us to choose metal materials.The following will introduce two types of metal materials, aluminum alloy and copper alloy, which have different mechanical properties and processing characteristics.
There are more than 1000 aluminum alloy grades registered in the world, each brand name and meaning are different, different grades of aluminum alloy in hardness, strength, processability, decoration, corrosion resistance, weldability and other mechanical properties and chemical properties there are obvious differences, each has its strengths and weaknesses.
hardness
Hardness refers to its ability to resist scratches or indentations. It has a direct relationship with the chemical composition of the alloy, and different states have different effects on the hardness of aluminum. The hardness directly affects the cutting speed and the type of tool material that can be used in CNC machining.
From the highest hardness that can be achieved, 7 series > 2 series > 6 series > 5 series > 3 series > 1 series.
intensity
Strength refers to its ability to resist deformation and fracture, commonly used indicators include yield strength, tensile strength and so on.
It is an important factor that must be considered in product design, especially when aluminum alloy components are used as structural parts, the appropriate alloy should be selected according to the pressure under.
There is a positive relationship between hardness and strength: the strength of pure aluminum is the lowest, and the strength of 2 series and 7 series heat-treated alloys is the highest.
density
Density refers to its mass per unit volume and is often used to calculate the weight of a material.
Density is an important factor for a variety of different applications. Depending on the application, the density of aluminum will have a significant impact on how it is used. For example, lightweight, high-strength aluminum is ideal for construction and industrial applications.
The density of aluminum is about 2700kg/m³, and the density value of different types of aluminum alloy does not change much.
Corrosion resistance
Corrosion resistance refers to its ability to resist corrosion when in contact with other substances. It includes chemical corrosion resistance, electrochemical corrosion resistance, stress corrosion resistance and other properties.
Corrosion resistance selection principle should be based on its use occasion, high-strength alloy used in a corrosive environment, must use a variety of anti-corrosion composite materials.
In general, the corrosion resistance of series 1 pure aluminum is the best, series 5 performs well, followed by series 3 and 6, and series 2 and 7 are poor.
processability
The machinability includes formability and machinability. Because formability is related to the state, after selecting the grade of aluminum alloy, it is also necessary to consider the strength range of each state, usually high strength materials are not easy to form.
If the aluminum is to be bent, drawn, deep drawing and other forming processes, the formability of the fully annealed material is the best, and on the contrary, the formability of the heat-treated material is the worst.
The machinability of aluminum alloy has a great relationship with the alloy composition, usually higher strength aluminum alloy machinability is better, on the contrary, low strength machinability is poor.
For molds, mechanical parts and other products that need to be cut, the machinability of aluminum alloy is an important consideration.
Welding and bending properties
Most aluminum alloys are welded without problems. In particular, some 5 series aluminum alloys are specially designed for welding considerations; Relatively speaking, some 2 series and 7 series aluminum alloys are more difficult to weld.
In addition, the 5 series aluminum alloy is also the most suitable for bending a class of aluminum alloy products.
Decorative property
When aluminum is applied to decoration or some specific occasions, its surface needs to be processed to obtain the corresponding color and surface organization. This situation requires us to focus on the decorative properties of materials.
Aluminum surface treatment options include anodizing and spraying. In general, materials with good corrosion resistance have excellent surface treatment properties.
Other characteristics
In addition to the above characteristics, there are electrical conductivity, wear resistance, heat resistance and other properties, we need to consider more in the selection of materials.
Orichalcum
Brass is an alloy of copper and zinc. Brass with different mechanical properties can be obtained by changing the content of zinc in brass. The higher the content of zinc in brass, the higher its strength and slightly lower plasticity.
The zinc content of the brass used in the industry does not exceed 45%, and the zinc content will be brittle and make the alloy performance worse. Adding 1% tin to brass can significantly improve the resistance of brass to seawater and Marine atmosphere corrosion, so it is called "navy brass".
Tin can improve the machinability of brass. Lead brass is commonly referred to as easy to cut national standard copper. The main purpose of adding lead is to improve the machinability and wear resistance, and lead has little effect on the strength of brass. Carving copper is also a kind of lead brass.
Most brasses have good color, processability, ductility, and are easy to electroplate or paint.
Red copper
Copper is pure copper, also known as red copper, has good electrical and thermal conductivity, excellent plasticity, easy hot pressing and cold pressure processing, can be made into plates, rods, tubes, wires, strips, foil and other copper.
A large number of products that require good electrical conductivity such as electrocorroded copper and conductive bars for the manufacture of EDM, magnetic instruments and instruments that must be resistant to magnetic interference, such as compass and aviation instruments.
No matter what kind of material, a single model basically can not meet all the performance requirements of a product at the same time, and it is not necessary. We should set the priority of various performance according to the performance requirements of the product, the use of the environment, the processing process and other factors, reasonable selection of materials, and reasonable control of costs under the premise of ensuring performance.
