What is 5 Axis CNC?
5-axis CNC machining is a advanced manufacturing process that uses computer numerical control (CNC) to move a workpiece or cutting tool along five distinct axes simultaneously: three linear axes (X, Y, Z) for basic positioning, plus two rotational axes (A, B, or C) for angled cutting.
Unlike traditional machining, this multi-axis movement eliminates the need for repeated workpiece repositioning, enabling seamless fabrication of complex, 3D geometries (e.g., curved surfaces, undercuts, or intricate cavities).
It is ideal for parts requiring high precision, such as aerospace components, medical implants, and custom industrial parts, as it reduces setup time, minimizes human error, and ensures uniform cutting across the entire workpiece.
Benefits:
- Increased efficiency shortens production lead times.
- Produces intricate shapes and undercuts in a single setup.
- Delivers smoother finishes with less need for post-processing.
What is Surface Finishing?
Surface finishing is the final step in manufacturing that improves both the visual appeal and functional performance of CNC machined parts. It involves applying a range of processes—mechanical, chemical, or electrochemical—to modify the outer layer of a component.
For CNC machined parts, finishing is more than just aesthetics. It ensures the part performs reliably in demanding environments while also meeting design and branding requirements.
Surface finishing is essential because it:
- Increases durability – Extends service life by enhancing wear resistance
- Protects against corrosion – Shields metals from moisture, oxidation, and chemicals
- Improves appearance – Provides smooth textures, polished surfaces, or vibrant colors

Surface Treatments in 5 Axis CNC Service
As Machined
Bead Blasting
Uses high-pressure air to propel small abrasive beads (e.g., glass, ceramic) onto the part surface. Creates a uniform, matte or textured finish (e.g., satin) while removing burrs or surface defects. Suitable for aluminum, steel, and titanium parts where a non-reflective surface is desired.
Anodizing
An electrochemical process that creates a thin, protective oxide layer on metal surfaces (most commonly aluminum). It improves corrosion resistance, adds color (e.g., black, silver, red), and enhances wear resistance. Ideal for consumer electronics, automotive trim, and aerospace parts.
Electroplating
Deposits a thin layer of metal (e.g., chrome, nickel, gold) onto the part surface via an electric current. Enhances conductivity (gold for electronics), corrosion resistance (nickel), or aesthetic appeal (chrome). Used for electrical components, decorative parts, and medical devices.
Electropolishing
An electrochemical finishing process that removes a thin layer of metal from the part surface to create a smooth, shiny, and ultra-clean finish. Unlike mechanical polishing, it works uniformly—even on complex geometries (e.g., intricate cavities, threaded holes) that are hard to reach with tools.
Brushed Finish
A brushed finish involves polishing the surface with abrasive belts or brushes to create a linear texture. It reduces glare, hides minor scratches, and provides a modern, aesthetic look. Common applications include consumer electronics, kitchen equipment, and automotive trim.
Powder Coating
Applies a dry powder (polyester, epoxy) to the part surface, then cures it with heat to form a durable, uniform coating. Offers excellent corrosion resistance, color variety, and impact resistance. Suitable for steel, aluminum, and magnesium parts (e.g., automotive frames, outdoor equipment).
Laser Engraving
Uses a high-powered laser to etch text, logos, or serial numbers onto the part surface. Creates permanent, high-precision markings without damaging the part. Ideal for branding, part identification (e.g., medical device serials), or decorative details on metals and plastics.

5 Axis CNC Machining Design Guidelines
For optimal results in 5-axis machining, follow these design guidelines to ensure manufacturability, reduce costs, and improve part quality:
Maintain Uniform Wall Thickness
Where possible, maintain consistent wall thickness to prevent distortion and ensure dimensional stability during machining. Recommended minimum wall thickness is 0.5mm for metals and 1.0mm for plastics.
Ensure Tool Access
Design features to allow adequate tool access, especially for deep cavities and internal features. Consider the length-to-diameter ratio of cutting tools when designing deep pockets or channels.
Use Fillets Instead of Sharp Corners
Incorporate radii instead of sharp corners to accommodate the round cutting tools and reduce stress concentrations. Internal corners should have a radius at least 0.5mm or 1/3 of the cavity depth.
Consider Feature Size
Ensure that small features are not too deep relative to their width to enable proper machining. The general rule is that feature depth should not exceed 4 times its width for milling operations.
