We all know that after the completion of the new product design, enterprises will choose to make a prototype first to see the effect, mainly to test whether the design of the product meets the requirements for use. The main materials for CNC metal prototyping are: aluminum, aluminum alloy, stainless steel, red copper, brass, steel, etc. Among them, aluminum is widely used in prototyping. Then let’s talk about the advantages and processes of aluminum CNC prototype machining.
Advantages of aluminum CNC prototype machining
1. aluminum CNC prototype machining parts not only have the characteristics of light weight and good strength, but also have a better appearance after oxidation treatment.
2. Aluminum has low density but high strength. It is close to or exceeds high-quality steel. It has good plasticity and can be processed into various profiles by CNC. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in industry, and its usage is second only to steel.
3. The aluminum CNC prototype machining parts can very accurately reflect the information expressed by the drawings, and the surface quality of the CNC prototype is high, especially after the surface spraying and silk screen printing are completed, even the products produced after opening the mold are even more radiant.
Aluminum CNC prototype machining Process
1. Programming: Write CNC machining programs according to the 3D drawings provided by customers.
2. CNC machining: CNC machining is carried out through CNC machining equipment according to the program written by the programmer, and the material is made into the prototype of the product.
3. Grinding: The hand board that has just been CNC machined on the machine will have many knife marks and skin edges on the surface, which needs to be polished with sandpaper.
4. Sandblasting: The effect of spraying a layer of sand on the surface of the prototype makes the samples of aluminum CNC prototype machining parts look more high-end and perfect.
5. Oxidation: Oxidation occurs on the surface of the parts processed by the aluminum CNC prototype to form a layer of film, so that the product is not easy to scratch.
6. Quality inspection: The aluminum CNC prototype machining parts can be packaged and shipped after being inspected by the QC department without any problems.
Surface treatment process of aluminum CNC prototype machining
1. During the proofing process of aluminum CNC prototype parts, the programmer first needs to write programs according to the drawings, and remove the remaining parts of the data through machine CNC machining to obtain the prototype of the prototype. The processing traces (knife marks and lines) of the aluminum CNC prototype processed by CNC on the machine are polished with sandpaper to make the appearance of the prototype smooth and smooth.
2. When the aluminum CNC prototype parts are sandblasted, the surface of the prototype is sprayed with a layer of sand, which makes the prototype sample look more textured. Then, the oxidation reaction of the aluminum CNC prototype machining parts will form a layer of film to make it not easy to scratch, so that the prototype has high protection and observability.
The above is an introduction to the related matters of aluminum CNC prototype machining, I hope it will be helpful to everyone. Most enterprises will choose CNC prototyping in the selection of prototyping. As a kind of CNC prototyping, aluminum CNC prototyping has many advantages of CNC prototyping, plus the advantages of aluminum itself, it is a very good choice.
