The PAEK (polyaryletherketone) family, of which PEEK is a member, is known for its high thermomechanical properties and is at the top of the list of...
When you go to create prototypes or parts for customized projects or for replacement, the choice of material is a very important phase of the design.
Different materials used for the same design, even belonging to the same family, can have very different performances.
Therefore it is good to know the needs of our project, what we expect from its technical properties, even in cases of greater stress. Finally, the price is also a discriminating factor that should not be underestimated, in relation to the piece that will be made.
This guide is intended to help you choose the most appropriate material for your CNC Technology project.
The materials on which CNC machining can be performed are mainly 5 groups:
The materials used for the production of CNC parts respond to the design needs, identified during the designing phase. Let's now see a consideration about each material and the most common reasons for use. On the other hand, if we has already identified our technical needs, we can directly view the technical data sheets to identify the most appropriate material for our project.
I state that in order to make an excellent choice of the material needed for our project, it is vital to know our own needs, bearing in mind what the function of this piece will be: this will be essential in choosing the material to use.
To clarify the concept of functional need we can make an analogy between the material chosen for a CNC part and a sports shoe: each sport has its own shoe, which is why it is not possible to climb a mountain with dance shoes. How I can't even play a rugby match in hiking boots. The same happens in the mechanical sector.
In order to identify the material we need, it is important to be clear about the technological, chemical and mechanical properties that my project will need.
Once I have identified the chemical, technological and mechanical needs of my project, I am ready to select the most suitable materials to meet them and, among these, perform the last skimming in a cost/effectiveness ratio.
To identify the design needs, let's ask ourselves the following questions:
Having a clear answer to each of these questions should have already allowed us to identify the best material for our project by identifying:
To help you make your decision, you can view the technical data sheets of the materials, including all their characteristics.
To conclude, we have seen that there is no absolute best material, but every project requires the correct choice of the right support.
We keep these rules in mind to choose the best material for our CNC project:
If you have now found the best material for your CNC project, you can make a cost quote on your file here.
If you still have doubts, don't worry: as you have seen. the choice of material is one of the most delicate design phases.
