Suitable for CNC machining of many materials, to find suitable materials for the product, subject to a variety of factors, need to follow a basic principle is: the performance of the material to meet the various technical requirements of the product and the environmental requirements for use. Selection of materials for mechanical parts can be considered from the following five aspects.

01 Whether the rigidity of the material is sufficient

Rigidity is the first factor to consider when choosing materials, because the product needs a certain degree of stability and wear resistance in the actual work, the rigidity of the material determines the feasibility of product design.

According to the characteristics of the industry, non-standard tooling design, usually choose 45 steel and aluminum alloy; machining tooling design, 45 steel and alloy steel will be used more; automation industry tooling design, most of them will choose aluminum alloy.

02 How about material stability

For a high-precision requirements of the product, if it is not stable enough, all kinds of deformation will occur after assembly, or the use of the process of deformation again, in short, with the temperature, humidity and vibration and other changes in the environment in the constant deformation, which is a nightmare for the product.
