Service Progress for Customized Anodizing CNC Milling Machine Parts
for Industrial Equipment
1. Initial Communication and Design Analysis
Submission of Requirements: The client provides the part's 3D CAD model (e.g., STP or IGES
files) and 2D technical drawings. The drawings must detail
dimensional tolerances, surface roughness, material specifications,
and the required anodizing type (e.g., standard or hardcoat) and
color.
Design for Manufacturability (DFM) Analysis: The engineering team evaluates the design's feasibility, with a
specific focus on both milling and anodizing. They check if the
geometry is suitable for CNC milling and assess if any deep holes,
sharp angles, or complex internal cavities might affect the
uniformity of the anodized layer.
2. Material Selection and Sourcing
Alloy Matching: For anodizing, alloys like 6061, 6063, or 7075 are typically chosen because they produce high-quality anodized
layers. The team will recommend the most suitable material based on
the part's strength requirements and the desired anodizing finish.
Quality Assurance: Materials are sourced from reliable suppliers and come with a
material certificate to ensure compliance with standards, which is
the foundation for subsequent processing.
3. Precision CNC Milling
Programming and Setup: A professional CAM programmer converts the CAD model into the
G-code that the CNC machine can execute. The machine is set up with
the correct tools and cutting parameters to ensure the part's
dimensional accuracy and surface finish.
Milling Operation: The raw material is processed on a CNC milling machine through
operations like milling, drilling, and tapping to create the
required geometry. The process is closely monitored to prevent
burrs and oil residue, which are crucial for preparing the surface
for anodizing.
4. Pre-treatment and Anodizing
Cleaning and Degreasing: This is the most critical step before anodizing. The parts undergo
multiple chemical cleaning procedures to completely remove cutting
fluid, grease, and fingerprints from the surface, ensuring the
anodized layer can adhere uniformly.
Anodizing Process:
Electrolysis: The part is submerged in a specific electrolyte solution (e.g.,
sulfuric acid) and an electric current is applied to form a porous
oxide film on the aluminum surface.
Coloring (Optional): If a specific color is required, the part is immersed in an organic
dye after the oxidation process, allowing the porous layer to
absorb the color.
Sealing: Finally, the part undergoes a sealing treatment in hot water or a
special solution to close the pores, which enhances corrosion and
wear resistance.
Hard Anodizing (Type III): For industrial parts that require extremely high wear resistance, Hard Anodizing is used, which produces a thicker, harder oxide layer.
5. Quality Control and Inspection
Dimensions and Tolerances: Precision equipment such as calipers and Coordinate Measuring Machines (CMMs) are used to re-measure the part's dimensions, ensuring the anodized
layer does not cause it to be out of tolerance.
Surface Quality Inspection: Specialized tools like anodizing thickness gauges and colorimeters
are used to check the layer thickness, color uniformity, and wear
resistance to ensure they meet the client's specifications.
6. Packaging and Delivery
Protective Packaging: Parts are individually or collectively packaged using bubble wrap,
foam, or custom trays to protect the anodized layer from scratches
or collisions during shipping.
On-Time Delivery: The products are delivered on schedule to meet the client's
production timeline.
Common Materials in Producing Customized Anodizing CNC Milling
Machine Parts for Industrial Equipment
1.Aluminum Alloys
(1)6061: Good strength and machinability, widely used in structural
parts
(2)6063: Excellent surface finish, suitable for anodizing and
decorative components
(3)7075: High strength, used in aerospace, defense, and precision
equipment
(4)5052: Strong corrosion resistance, suitable for housings and
enclosures
2.Stainless Steel
(1)304: General-purpose stainless steel with good strength and
corrosion resistance.
(2)316: Superior corrosion resistance, ideal for harsh environments
Note: Stainless steel cannot be anodized; instead, it is treated by
polishing, passivation, or plating
3.Titanium Alloys
Lightweight, high strength, excellent for aerospace and medical
applications
Can be anodized to create colorful oxide surface layers
4.Copper
Excellent electrical and thermal conductivity
Commonly used for electrical contacts and heat dissipation parts
Surface treatments include plating or anti-oxidation coating (not
anodizing)
5.Brass
Good machinability, corrosion resistance, and aesthetic appearance
Often used for decorative, plumbing, and electrical parts
Typically finished with plating or coating rather than anodizing
