"3D Hubs is able to do the manufacturing in half the time, and that’s a huge advantage to us. "

Julian Jiminez

"Amazing experience. All the exceptions fulfilled. Exceptional quality and surface finish. Lead time faster than initially stated."

Harm Medendorp

"When we started working with 3D Hubs, we noticed an immediate difference in lead time and product cost. Using the DfM tools for CNC machining to quickly iterate, we managed to reduce production costs by up to 50%."

Chandra Harsha

"Very fast and agile. Parts meet quoted quality with reasonable price. The support team from 3DHubs is also very responsive and helpful."

Available CNC machining services

Our network of Manufacturing Partners gives you easy access to diverse machining capabilities to serve all your manufacturing needs.

Name Description
CNC Milling service CNC milling is a subtractive manufacturing process that rapidly removes material from metal or plastic blocks to produce precision parts with tight tolerances.
Learn more about our milling capabilities
CNC Turning service CNC turning produces parts with cylindrical features by removing material from metal or plastic rods using cutters, center drills or live tooling.

Available surface finishes for CNC machining

Surface finishes are applied after machining and can change the appearance, surface roughness, hardness and chemical resistance of the produced parts.

  Name Description
cnc-surface finish-as-machined-1 As Machined (standard) ~125 RA µin (3.2 RA µm). Minor tool marks will be visible on the part.
cnc-surface-smoothed Smoothed Parts are machined at a lower feed rate in order to achieve a surface roughness of ~62.5 RA µin (1.6 RA µm). Surface roughness can be decreased up to ~32 RA µin (0.8RAµm) upon request.
cnc-surface finish-bead blasted-1 Bead Blasted Bead blasting adds a uniform matte or satin surface finish on a machined part, removing all tool marks. Mainly used for aesthetic purposes.
cnc-surface finish-anodized-1 Anodized Clear or Color (type II) Anodizing adds a thin, hard, non-conductive ceramic coating on the surface of aluminum parts, increasing their corrosion and wear resistance. Available in a variety of colors.
cnc-surface finish-anodized-2 Anodized Hardcoat (type III) Hardcoat anodizing produces a thicker ceramic coating providing excellent corrosion and wear resistance. for functional applications.
cnc-surface finish-powder coating-3 Powder Coated Powder coating adds a thin layer of strong, wear and corrosion resistant protective polymer paint on the surface of a part. Available in a large range of colors.
electropolishing (temporary) Electropolished Electropolishing is an electrochemical process used to polish, passivate and deburr metal parts. It is useful to reduce surface surface roughness.
Black oxide (stock photo) Black oxide Black oxide is a conversion coating used to improve corrosion resistance and minimize light reflection.
chromate_conversion (stock photo) Chromate conversion coating (Alodine/Chemfilm) Chromate conversion coating is used to increase the corrosion resistance of metal alloys while maintaining their conductive properties.
brushed finish Brushing Brushing is produced by polishing the metal with grit resulting in a unidirectional satin finish.

Other surface finishes are also available. Learn more about our metal and plastic surface finishing capabilities here.
