Parts Milling Stainless Steel Machining Parts
CNC Machining Advantages:
1. Exceptional Precision and Repeatability: CNC machining, encompassing milling and turning,
excels at producing parts with exceptionally tight tolerances, making it a preferred choice for
high-end industries like aerospace, aviation, and automotive.
2. Versatile Material Compatibility: Most materials used in CNC machining exhibit excellent and
fully-isotropic physical properties, rendering them suitable for a wide spectrum of engineering
applications.
3. Cost-Effective for Medium-Volume Production: CNC machining is a cost-effective method for
manufacturing low-to-medium quantities of metal parts, accommodating single prototypes to
production runs of up to 1,000 units.
Product Details
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.

FAQ's
1. 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.
2. What's the general surface texture of CNC milled and turned parts?
In the realm of CNC machining, as-machined milled parts typically exhibit a surface roughness of
approximately 3.2μm (or 1.6μm in the case of relatively new machines).
On the other hand, when it comes to turned parts, we can achieve a smoother surface with a
roughness of 0.8μm.
This means that machining speed adjustments are not necessary to attain this level of surface finish.
