There is a lot of knowledge about the processing service of CNC machining. It includes material selection, processing, surface treatment, transportation and packaging.
There are many materials suitable for CNC machining. To find materials suitable for products, one of the basic principles that need to be followed is that the performance of the material should meet the technical requirements and environmental use requirements of the product.
When choosing mechanical materials, there are five aspects for you to have a consideration.
01、The rigidity of the material
Rigidity is the first factor to consider when choosing materials, because the product requires a certain stability and wear resistance in actual work, and the rigidity of the material determines the feasibility of product design.
Before selecting the material, first consider the use scenario of the part, what characteristics are required, and then select the material with the corresponding performance.
02、Stability of material
For a product with high-precision requirements, if it is not stable enough, various deformations will occur after assembly, or deformation will occur again during use. In short, it is constantly deformed with the changes of the environment such as temperature, humidity and vibration, which is simply a nightmare for the product.
03、Material processing performance
The processing performance of the material means whether the parts are easy to process. Although stainless steel is rust-resistant, it is not easy to process. Its hardness is high, and it is easy to wear tools during processing. Processing small holes on stainless steel, especially threaded holes, is easy to break the drill bit and the tap, which will lead to very high processing costs.
04、Anti-rust treatment of materials
Anti-rust treatment is related to the stability of product use and appearance quality. For example, 45 steel usually chooses "blackening" treatment for rust prevention, or the parts are sprayed with paint and plastic spraying. It can also be protected by oil sealing or anti-rust solution during use according to the requirements of the environment...
There are many anti-rust treatment processes, but if the above methods are not suitable, the material must be changed, such as stainless steel. In any case, the anti-rust problem of the product cannot be ignored.
05、the cost of materials
Cost is an important consideration in the selection of materials. Titanium alloy is light in quality, has high specific strength and good corrosion resistance. It is widely used in automobile engine systems and plays an immeasurable role in energy saving and consumption reduction.
Although titanium alloy parts have such superior performance, the main reason that hinders the widespread use of titanium alloy in the automotive industry is the high cost. If you don't really need its performance, choose a cheaper material!
