3-axis machining Vs 5-axis Machining-Which Suits Your Project?
Choosing the right machining method is not only the key to achieving efficient and precise production, but also a way to reduce costs. Both 3-axis and 5-axis machining have their own advantages, capable of handling everything from complex curved surfaces to rotationally symmetric parts. Understanding their characteristics will help you make the best choice for each project.


Feature
3-Axis Machining
5-Axis Machining
Movement
3-axis machining is a precise and versatile method for producing flat surfaces, slots, holes, and simple 3D parts. It offers high accuracy, repeatability, and efficiency, making it ideal for small-batch or straightforward part production. Advanced tooling ensures excellent surface finish and dimensional precision.
Simultaneous, or continuous, 5-axis machining allows all five axes to move at the same time, enabling the machine to adjust its position continuously without stopping. This approach can significantly increase machining speed and efficiency, as there are no interruptions between cutting passes, while also improving surface finish on complex parts.
Complexity
Suitable for flat surfaces, slots, and simple 3D parts; simple in structure.
Surface Quality
Provides smoother surfaces withfewer tool marks, though the surfacequality on complex curves is stillinferior to 5-axis machining.
When machining complex surfaces or intricate structures, it achieves smoother finishes with fewer tool marks.
Efficiency
High production efficiency, but complex parts require multiple setups.
Faster production with fewer setups.
Best For
Flat surfaces, slots, and simple 3D parts.
Components with complex structures and high precision requirements.
Cost & Investment
Both part and equipment costs are lower than those of 5-axis machining.
Higher machine and programming costs.

Surface Finish and Post-Processing Options

As machined
The machined or deburring finish is the standard finish where unwanted attach chips are removed with deburring tools, and sharp edges are chamfered to smooth the surface (3.2 μm).

Bead Blasted
Bead blasting produces a matte texture, removing all the marks of machining tools. It applies to ABS, Aluminum, Brass, Stainless Steel, and Steel parts.

Anodizing
Anodizing involves adding an aluminum oxide coating to aluminum and its alloys. The layers, which come in various colors, increase strength and shield the surface from corrosion.

Alodine
Provides excellent corrosion resistance property to the aluminum parts with greenish-gold color. It is the low-cost and quick surface finishing approach.

Polishing
Physical rubbing of a metal surface to create a shiny surface is called a polishing surface finish. It increases the reflectivity and does not affect the dimensional stability of parts.

Brushing
Brushing is achieved by applying an abrasive brush to the metal surface, which produces a unidirectional satin finish. And it is not recommended for highly corrosive materials.

Sanding
Provides a random, non-linear texture with a shiny, high gloss finish. However, it might be unable to create sharp corners and pockets

Black-Oxide
Black oxide finish reduces surface reflectivity and offers mild corrosion protection. It involves adding a thin layer of magnetite to the surface.

Electroplating
Electroplating increases the hardness of the steel &aluminum parts. It offers excellent corrosion, wears, and abrasion resistance.

Electroless Nickel Plating
A thin layer of Nickel is created on the surface from a nickel-containing solution without electrolysis. Electro-less nickel plating provides a shiny appearance, excellent hardness, abrasive, wear, and corrosion-resistance to the substrate material.

Chrome Plating
Chrome plating is widely used in various industries, which not only enhances the beautiful appearance of the product, but also improves the performance of the product, such as corrosion resistance, oxidation resistance, abrasion resistance, hardness, etc.

Passivation
Enhance the appearance and functionality of the parts. After Passivation, parts of Steel and its alloys become super resistive from corrosion.
What is CNC Milling and How Does it Work?
CNC milling is a subtractive manufacturing process. It starts by fixturing a block of metal or plastic material inside the CNC mill. Using G-code, the CNC machine is programmed to rapidly mill out parts from the block of raw material. Our 3- and 5-axis CNC machines are equipped with various toolsets to maximize efficiency and production speed. Machined plastic parts are left as-milled, which typically means they show visible tool marks. Some metal parts allow more finishing choices like anodizing and chromate plating. When the run is complete and your required surface finish is applied, parts are boxed and shipped shortly thereafter.
