Surface Finishes for 5 Axis CNC Machining
BOYI provides surface finishes for 5-axis parts, enhancing appearance, smoothness, durability, and hiding tool marks for high-quality results.
Specific to aluminum, this finish can range from smooth to matte or gloss, with customizable colors. A thin layer (0.002mm to 0.04mm) is removed.
The polished finish offers a high gloss, smooth surface with Ra 0.8μm (Ra 32μin) roughness, ideal for mirror-like applications.
Bead Blasting
Metals or plastics parts surface is left with a smooth, matte appearance, with no thickness removal specified.
Black Oxide
Black oxide is a corrosion-resistant treatment for metals, providing a matte black finish, mild rust protection, and improved wear resistance.
Powder Coating
Applicable to metals, offering matte, gloss, or textured finishes with customizable colors. Thickness removed ranges from 0.05mm to 0.15mm.
As Machined
This finish retains visible tool marks and is suitable for both metals and plastics. There is no specific thickness removed in this finish.
Brushing
Brushing produces a satin texture on parts, offering a smooth, uniform finish while concealing minor flaws.
Electroless Nickel Plating
Electroless Nickel Plating provides a uniform, corrosion-resistant finish on metals, with excellent hardness and wear resistance.
Chromate Conversion Coating
This finish can appear smooth or matte, often with a clear or slight yellow tint. A very thin layer (0.25–1 micrometer) is removed.
E-Coating
This finish, suitable for metals, can be matte or gloss, with black as the most common color.
Painting
Available for metals and plastics, this finish can be matte, gloss, or textured, with color matching possible.
Heat Treatment
Heat treatment enhances metal properties such as hardness, strength, and toughness through controlled heating and cooling processes.

Understand the 5 Axis CNC Machining Process
5-axis CNC machining expands upon traditional 3-axis movement by adding two rotational axes. This allows the cutting tool to approach the workpiece from nearly any angle, enabling the production of complex geometries with fewer setups and greater precision.
How Does 5-axis Machining Work?
5-axis machining is a cutting-edge form of CNC machining where the cutting tool moves along five different axes, rather than just three. In a typical 3-axis machine, the spindle moves vertically, horizontally, and in depth. With 5-axis machining, two additional axes come into play—either by allowing the table to rock on two separate axes or by enabling the spindle to swivel on two axes.
These extra degrees of freedom let the cutting tool approach the workpiece from virtually any angle, making it possible to produce highly complex geometries that would be challenging or even impossible with traditional 3-axis machines.
Simultaneous 5-Axis vs. 3+2-Axis CNC Machining
Both methods extend beyond traditional 3-axis machining, the key difference is how the extra axes are utilized:
5-Axis Machining:
The tool moves continuously along five axes. This simultaneous multi-axis movement allows the cutting tool to approach the workpiece from any direction, enabling the production of highly complex geometries in a single setup with dynamic, continuous adjustments.3+2 Axis Machining:
This method uses a 3-axis machine combined with two additional rotational axes that are used to position the workpiece or tool before machining. Once set, the rotational axes remain fixed during the cutting process.
Trunnion-Style or Swivel-Rotate-Style 5-Axis CNC Machining
Trunnion-Style:
In this setup, the workpiece is mounted on a rotating table (trunnion) that pivots around a horizontal axis. This allows continuous multi-axis movement of both the workpiece and the cutting tool, making it ideal for large or complex parts that benefit from dynamic positioning.Swivel-Rotate-Style:
Here, the cutting tool head swivels and rotates, while the workpiece remains fixed or moves on a standard 3-axis table. This configuration offers excellent flexibility in tool orientation and is often favored for smaller parts or when precise tool access is critical.
Applications of 5 Axis CNC Machining
- Turbine blades
- Engine components
- Transmission parts
- Surgical instruments
- Implants and prosthetics
- Molds and dies
- Military equipment components
- Electronic enclosures
- Aerospace brackets
- Automotive custom parts
Key Benefits of 5 Axis CNC Machining
- Machines intricate designs from any angle, cutting down on setups.
- Fewer setups mean less handling and improved precision.
- Maintains optimal tool angles for smoother surfaces.
- Reduces deflection and vibration for cleaner cuts.
- Combines multiple operations into one setup.
- Efficient tool paths minimize waste.
About 5-Axis CNC Machining FAQ's
BOYI 5-axis CNC machining provides high precision with tight tolerances, often reaching accuracies within 0.001mm or less.
5-axis machining is ideal for parts with complex shapes, such as turbine blades, aerospace components, medical implants, and custom automotive parts.
3-axis machining only allows movement along three axes (X, Y, Z), while 5-axis machining adds two more rotational axes, allowing for more flexible tool positioning and the ability to machine more complex geometries in one setup.
