5-Axis Machining Surface Finishes
Choose from 10+ finishing options for 5-axis machined parts. Our surface treatments help improve appearance, protection, and functional performance for both prototype and production applications.
As Machined
As-machined parts retain the surface directly from CNC machining, including visible tool marks. This is a cost-effective option for functional parts where cosmetic appearance is not the primary concern.
Anodizing
Anodizing improves corrosion resistance and surface durability while allowing color dyeing. It is commonly used for aluminum parts requiring both protection and appearance enhancement.
Black Oxide
Black oxide is a conversion coating commonly used on ferrous metals to reduce light reflection and provide mild corrosion resistance, typically with a post-treatment such as oil or sealant.
Sand Blasting
Sand blasting uses pressurized abrasive media to create a uniform matte texture and improve surface consistency. It is often used to reduce the visibility of machining marks and prepare parts for further finishing.
Powder Coating
Powder coating applies a durable protective layer with a wide range of color and texture options. It is commonly used to improve appearance and corrosion resistance on a variety of metal parts.
Electroplating
Electroplating deposits a thin metal coating onto the part surface to improve corrosion resistance, appearance, and, in some cases, wear performance or conductivity, depending on the plating type.
Polishing
Polishing reduces surface roughness and creates a smoother, more refined appearance. Depending on the material and polishing level, it can produce finishes ranging from satin to high gloss.
Brushed Finish
A brushed finish creates a uniform, unidirectional satin texture that improves visual consistency and helps reduce the visibility of light scratches and machining marks.

Service FAQs
1. Do you offer instant online quotes for CNC machining?
Not in the platform sense. At JIZAO, every RFQ is reviewed by real engineers rather than an automatic quoting system. We typically respond within 12 hours, and for standard projects, we can usually provide a feasibility review, optimization suggestions, and quotation within 24 hours after receiving sufficient project information.
Before production, we check the key manufacturing risks in your design and communicate any concerns clearly. After order confirmation, we continue to update you on project progress throughout production. All parts are inspected against the drawing before shipment, and we do not send parts that do not meet dimensional requirements to our customers.
2. What information do you need for a CNC machining quote?
To review your project properly, we recommend sending 3D files or 2D drawings, along with the material, quantity, tolerance requirements, surface finish requirements, and delivery address. The more complete the information, the more accurate our engineering assessment and quotation will be.
3. What is your typical lead time for CNC machined parts?
Lead time depends on part complexity, quantity, material, and process requirements. Prototype parts are typically shipped within 2–5 days, and for suitable projects, selected parts can be delivered in as fast as 1 day. Low-volume production usually takes around 15–25 days.
4. What tolerances can your CNC machining services achieve?
For suitable CNC machining projects, tolerances can be controlled as tight as ±0.025 mm (±0.001″). The actual achievable tolerance depends on the material, part size, geometry, feature type, and inspection requirements shown on the drawing.
