View MoreCNC Milling Surface Finishes
Gain access to quality surface finishing for custom CNC milled parts to remove aesthetic flaws and improve the appearance of your products. We also provide rigid protection and additional resistance and strength to your parts through superior surface finishes.
As Machined
As machined finish leaves the surface straight from the CNC machine, providing a cost-effective option with tool marks.
Anodizing
Anodizing increases corrosion resistance and wear properties, while allowing for color dyeing, ideal for aluminum parts.
Polishing
Polishing achieves a high gloss finish, reducing surface roughness and enhancing the aesthetic appeal of metals.
Sand Blasting
Sand blasting uses pressurized sand or other media to clean and texture the surface, creating a uniform, matte finish.
Brushed Finish
A brushed finish creates a unidirectional satin texture, reducing the visibility of marks and scratches on the surface.
Powder Coating
Powder coating applies a thick, wear-resistant layer with excellent color and texture options, suitable for a variety of surfaces.
Electroplating
Electroplating bonds a thin metal layer onto parts, improving wear resistance, corrosion resistance, and surface conductivity.
Black Oxidize
Black oxidize is a conversion coating for ferrous metals that improves corrosion resistance and minimizes light reflection.
Electropolish
Electropolish is a chemical process that smooths and brightens surfaces while improving corrosion resistance.
Alodine
Alodine coating provides corrosion protection and improves paint adhesion, mainly used on aluminum surfaces.

How CNC Milling Works?
CNC milling is a precise manufacturing process that involves removing material from a workpiece using rotating cutting tools. The process begins with a digital design, typically created in CAD software. This design is then converted into a CNC program, which dictates the movements of the milling machine.
The workpiece is securely fastened to the machine’s table, and the cutting tool, mounted on a spindle, rotates at high speeds. The machine follows the programmed path, making precise cuts to shape the material into the desired form. CNC milling can create complex shapes and features, such as slots, holes, and contours, with high accuracy.
Three-axis milling moves the tool along the X, Y, and Z axes. Four-axis milling adds rotation around one axis, while five-axis milling allows rotation around two axes, enabling more intricate designs. This versatility makes CNC milling essential in various industries, from aerospace to medical devices.
