Cost Considerations for CNC Machining Materials
The cost of materials in CNC machining can fluctuate significantly due to the extensive array of
available options. Each material carries its unique price tag, and the inherent physical properties
of each material play a substantial role in determining machining costs.
For those seeking to manufacture metal components, Aluminum 6061 stands out as the most
cost-effective choice.
On the other hand, ABS ranks as the most budget-friendly option among materials.
As for the influence of machining complexity on costs, stainless steel serves as an illustrative example.
Its inherent hardness, surpassing that of aluminum, renders it more challenging to machine,
consequently elevating the overall machining expenses.
Here is a comprehensive overview of the most popular materials.

Company Profile
Characteristics of CNC Machining
One of the defining strengths of CNC machining lies in its ability to consistently fabricate sturdy parts
using an extensive range of materials.
CNC machines are capable of processing virtually every engineering material.
In contrast to 3D printing, parts crafted through CNC machining exhibit fully-isotropic physical
properties, mirroring the properties of the bulk material from which they were machined.
CNC machining predominantly focuses on metals, serving purposes ranging from prototyping to
larger-scale production runs.
While machining plastics can present challenges due to their lower stiffness and lower melting
temperatures, there is value in employing CNC machining for crafting functional prototypes from
plastic materials before transitioning to larger-scale production through methods
such as injection molding.
How do you speed up CNC manufacturing?
The pace of manufacturing in CNC machining is influenced by various factors, encompassing part
design and the desired surface finish.
One illustrative approach to expedite the machining process is by incorporating fillets instead of
sharp corners in your design.
This design adjustment allows for the use of standard tools throughout production, eliminating the
need for tool changes during machining and thereby enhancing manufacturing speed.
