Aluminum in CNC Machining
In CNC machining, raw aluminum is gradually cut down to form the desired shape, a process controlled with precision by a CNC machine to produce almost any three-dimensional object. Aluminum alloys offer high machinability, ductility, and an excellent strength-to-weight ratio. They also possess high thermal and electrical conductivity, low density, and natural corrosion resistance, and they can be anodized for added protection. The strength-to-weight ratio of aluminum makes it perfect for applications requiring metallic strength without excessive mass. Custom aluminum machining is an excellent choice for precise and versatile machining needs.

CNC Machining Surface Finishes
Lewei Precision offers a wide range of surface finishing solutions tailored to enhance the performance, durability, and appearance of parts produced through our 3-axis and 4-axis CNC machining services.
As machined
As-machined aluminum parts come directly from the mill with visible tool marks. This finish is cost-effective, maintains tight tolerances, and has a surface roughness ranging from Ra 0.2 to 3.2 µm.
Anodizing
Anodizing enhances aluminum’s corrosion and wear resistance by thickening its oxide layer. It can be dyed in various colors, improving heat dissipation and offering aesthetic and functional benefits.
Powder Coating
Powder coating provides bright, durable, UV-resistant colors. It involves spraying dry paint on prepped aluminum, then baking for a smooth, corrosion-resistant finish. Environmentally friendly, it avoids solvents and VOCs used in traditional liquid painting.
Electroplating
This process uses electrolysis to deposit a thin metal layer on aluminum, enhancing its conductivity, strength, and resistance to UV light, abrasion, and corrosion. Common deposition metals include copper, nickel, gold, titanium, silver, zinc, and chromium.
