This is one of the reasons why LVMA is trusted by many customers.
CNC Machining Capabilities in Milling and Turning
CNC Milling
Using multi-axis tools, CNC milling accurately removes material from solid workpieces along programmed paths. This process excels at creating complex shapes like planes, curved surfaces, and slots, supporting metals, engineering plastics, and composites. It is a highly versatile solution, widely used in small- and medium-batch productions.

CNC Turning
By rotating workpieces at high speeds while feeding tools in axial and radial directions, CNC turning efficiently produces cylindrical components such as shafts, cones, and threads. Modern CNC lathes can integrate multiple functions such as boring, grooving, and threading, enabling versatile and high-volume production.

CNC Machining Surface Finishes
LVMA CNC provide 10+ different surface finishing solutions. Our engineers analyze the specific applications and materials involved to select the most suitable surface finishing process for your CNC machining project.
As Machined
As Machined finish refers to the original surface state of a part, without any additional surface treatment.
Surface retains tool marks, it is lower production costs.
Applicable Materials
Stainless Steel, Aluminum
Polishing
Polished with a grinding wheel to achieve a smooth and glossy surface on custom metal parts.
Applicable Materials
Zinc, Aluminum, Acrylic
Electropolish
Electropolishing removes microscopic peaks on the metal surface, achieving a surface roughness (Ra) of 0.1–0.4 μm.
Applicable Materials
Steel, Stainless Steel
Electroplating
Electroplating applies a metal layer to metal or plastic parts to enhance appearance and corrosion resistance, with adjustable thickness.
Applicable Materials
Aluminum, Steel, Stainless Steel
Anodizing
Anodizing is mainly suitable for aluminum alloys. It can be dyed in various colors, the coating is resistant to peeling, and it significantly enhances corrosion resistance.
Applicable Materials
Aluminum
Brushed Finish
Brushed surfaces have uniform fine lines, a soft sheen, and are effective at hiding fingerprints and scratches.
Applicable Materials
Stainless Steel
Sand Blasting
Sand blasting forms a matte surface, conceals scratches, reduces gloss, and enhances coating adhesion.
Applicable Materials
Titanium, Steel, Aluminum
Powder Coating
Powder coating forms a smooth, durable surface, resists scratches and corrosion, enhances aesthetic appeal, and achieves an adhesion rating of 5B.
Applicable Materials
Aluminum, Copper, Zinc
Heat Treatment
Heat treatment changes the metal’s structure to make parts harder, stronger, and more durable.
Applicable Materials
Steels, Titanium, Aluminum, Copper
Black Oxidize
Black oxidizing gives metal parts a black finish, protects against rust, and reduces glare.
Applicable Materials
Stainless Steel, Steel
Alodine
Alodine forms a thin protective layer on aluminum, prevents rust, and improves paint or coating adhesion.
Applicable Materials
Aluminum
