Surface finishing options

CNC as machining surface finish on metal part

As Machining (Standard)

Surface roughness can be precisely specified using an Ra value. Our standard Ra range is 0.4-3.2 um, ensuring a consistent and high quality surface finish.

Sand blasting

Sandblasting size: Our standard sandblasting size is 80um, and we can flexibly provide sizes in the range of 50 - 120um to meet your specific requirements.

Anodizing type 2 surface treatment

Our standard colors: clear/natural, black, red, green, blue, yellow/gold. This finish perfectly matches the specified RAL number, ensuring color consistency and aesthetic appeal.

Anodizing type 3 surface treatment for CNC aluminum components

Anodized Type 3 surface treatment

Standard colors: black or gray. This surface treatment provides a softer appearance but significantly enhances surface protection, making it ideal for applications where durability and resistance to wear and corrosion are critical.

The finishing options shown above represent just a portion of what we can provide. We also offer customized finishing solutions designed to enhance both performance and appearance of your parts. Get in touch today for your tailored solution!

CNC Machining Applications

Leverage alloys (6061 Al) and engineering plastics (POM,PVC) with fast turnaround times for design validation.

5 axis cnc milled aluminum production applications

Production Parts

Achieve ±0.001” tolerance and advanced surface finishes for demanding end-use parts with certifiable material traceability.

Rapid Tooling

Capable of machining dense alloys such as 5052 aluminum and stainless steels, CNC machining excels in producing precision molds and fixtures.

CNC Machining FAQs

What is CNC machining?

CNC (Computer Numerical Control) machining is a subtractive manufacturing process where automated machines precisely cut, drill, and shape materials according to digital 3D CAD files. At TiRapid, we use advanced 3-axis, 4-axis, and 5-axis machining centers to produce accurate and repeatable parts across metals and plastics.

What is the difference between CNC milling and CNC turning?

CNC Milling uses rotating cutting tools to remove material from a stationary workpiece—ideal for flat surfaces, slots, and complex 3D geometries.
CNC Turning rotates the workpiece against a cutting tool—best for shafts, bushings, and cylindrical parts.
TiRapid provides both services, ensuring flexible solutions for different component designs.

What are TiRapid’s machining capabilities and size ranges?

Milling (3/4/5-axis): 1–3000 mm (L), 1–1000 mm (W), 0.5–600 mm (H)
5-axis precision milling: up to 700 × 500 × 400 mm
Turning: Ø1–600 mm, length up to 700 mm
This covers everything from micro parts to large structural components.

What tolerances can TiRapid achieve?

Standard: ±0.05 mm
Precision CNC: ±0.01 mm
EDM/Wire-EDM: ±0.002–0.005 mm
Surface finishes reach up to Ra 0.4 μm (turning/milling) and Ra 0.2 μm (EDM). We comply with ISO 2768 and can meet H7 fits when required.

What materials can be machined at TiRapid?

We provide 100+ metals and plastics, including:

Metals: Aluminum (6061, 7075, 2024), Stainless Steel (304, 316, 410), Steel, Copper, Brass, Titanium, Magnesium.
Plastics: ABS, Nylon, POM (Delrin®), PC, PMMA, PVC, PTFE.
Our team also supports custom material sourcing on request.

What finishing options do you provide?

TiRapid offers 60+ surface treatments, including anodizing (Type II & III), powder coating, bead blasting, polishing, electroplating, passivation, and custom coatings to improve functionality and appearance.

How much does CNC machining cost?

Costs depend on material, geometry, tolerances, surface finish, and order volume.

Prototypes: as fast as 1 day delivery.
Batch production: strong capacity over 30,000 parts/month.
To save cost: simplify geometries, avoid unnecessary tight tolerances, and choose common materials. TiRapid provides free DFM reports to help optimize designs.

Do you offer rapid or quick-turn CNC machining?

Yes. For urgent projects, we can deliver prototypes within 1 day. Thanks to our in-house facility and flexible scheduling, TiRapid ensures both speed and precision without compromising quality.

How do you guarantee the quality of my parts?

TiRapid follows ISO9001 quality standards and uses a complete inspection process:

CMM 3D measurement
2D profile inspection (PROJ)
Surface roughness tests
Precision hole & thread gauge checks
Inspection reports (COA, FAIR, PPAP) are available on request.

What industries use TiRapid CNC machining services?

Our components are widely used in automotive, aerospace, medical devices, robotics, electronics, automation, energy, and racing industries. We support both functional prototypes and end-use production parts.

Why choose CNC machining over 3D printing or molding?

CNC machining provides:

Superior accuracy for tight tolerances.
Material flexibility with metals and plastics.
Excellent repeatability for both prototypes and volume production.
Unlike molding, CNC machining requires no expensive tooling, and compared to 3D printing, it achieves better surface finishes and mechanical strength.
