Surface Finishes for 5 Axis CNC Machining

With an extensive list of surface finishes available, RapidDirect can enhance the surface quality of your 5-axis machined parts. Applying these finishes help improve the appearance of the components, their surface roughness, hardness, corrosion resistance, and more. They also hide visible tool marks on the products’ surfaces.

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.

Tumbling

Tumbling smooths and polishes small parts by friction and abrasion in a barrel, offering a consistent but slightly textured finish.

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.

Heat Treatment

Heat treatment alters the mechanical properties of metal to increase its hardness, strength, or ductility.

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.

FAQs

Can 5-axis machining provide tight tolerance?

Yes, 5-axis CNC machining is renowned for its ability to achieve exceptionally tight tolerances. It can typically maintain precision within ±0.005 mm. This high level of accuracy is due to the machine’s capability to access five sides of a part in a single setup, reducing the number of setups required and minimizing errors associated with repositioning. The simultaneous movement along five axes allows for closer tool paths, ensuring precise adherence to design specifications, especially for complex geometries.
How much does your 5-axis milling service cost?

The cost of 5-axis CNC milling services can vary widely based on several factors such as the complexity of the part, the type of material used, and the required precision. Generally, prices might range from $75 to $250 per hour depending on these variables. For a specific quote, it’s best to provide detailed drawings and specify material requirements on RapidDirect online platform so that a more accurate estimation can be calculated. Remember, while 5-axis machining might have a higher hourly rate, it often reduces the total production time and number of setups needed.
When should I choose 5-axis CNC machining?

Opt for 5-axis CNC machining when manufacturing parts with complex geometries, intricate details, or when high precision is critical. This technology is ideal for parts that require machining from multiple sides in a single setup or where multiple tool angles are necessary to achieve the design. Industries such as aerospace, medical, and automotive, where the geometrical complexities and tight tolerances are common, significantly benefit from 5-axis machining. It is also preferable when aiming to reduce lead times and improve surface finishes without compromising on detail.
What’s the difference between 5-axis machining and 3-aixs machining?

The main difference between 5-axis and 3-axis machining lies in their respective capabilities and the complexity of parts they can handle. 3-axis machining operates along three axes (X, Y, and Z), suitable for parts with relatively simple geometries. It typically requires multiple setups and repositioning to reach all sides of the part. Conversely, 5-axis machining adds two additional rotational axes, allowing the cutting tool to approach the part from virtually any direction. This capability makes it ideal for complex shapes, reducing setup times and improving precision by minimizing handling.
What is 5-axis CNC machining?

5-axis CNC machining is an advanced form of computer numerical control (CNC) technology that allows a machine to move a tool or part along five different axes simultaneously. This enables the machine to create highly complex shapes and features in a single setup, increasing precision and efficiency. It’s commonly used in industries like aerospace, automotive, and medical for creating intricate components.
How does a 5-axis CNC machine work?

A 5-axis CNC machine operates by allowing the cutting tool or part to move in five different directions: along the X, Y, and Z axes, and rotating around the A and B axes. This capability allows for machining complex geometries without needing multiple setups or repositioning, which reduces human error and increases accuracy. The machine’s advanced software ensures precise control over every movement.
What is the tolerance of 5 axis CNC machining?

Yinchen’s 5-axis CNC machining can achieve extremely tight tolerances, often tighter than ±0.001 inches, depending on the material and part complexity. Their advanced machines and strict inspection processes ensure parts are manufactured according to your design specifications and GD&T (Geometric Dimensioning and Tolerancing) requirements, delivering precise, high-quality components.
