CNC Machining Surface Finishes at Kaiao-RPRT

Looking for the perfect finish? At Kaiao-RPRT, choose from 20+ options to boost both function and style for your CNC parts, crafted with precision from our China facility for clients worldwide.

As Machined Finish

The as machined finish (Ra1.6) comes straight from our CNC machines at Kaiao-RPRT, offering a cost-effective solution with visible tool marks for clients worldwide who value efficiency and precision.

Anodizing

Anodizing at Kaiao-RPRT boosts corrosion and wear resistance for aluminum parts, with the added perk of color dyeing, perfect for clients worldwide seeking durability and style.

Polishing

Polishing creates a high-gloss, mirror-like finish that minimizes surface roughness and elevates the visual appeal of metals like aluminum, steel, and brass. It’s perfect for applications where a sleek, professional look is key, such as in consumer electronics or automotive components.

Sand Blasting

Sand blasting uses pressurized sand or other media to clean and texture the surface, delivering a uniform, matte finish. This process is ideal for removing imperfections and creating a consistent look on metals like aluminum or steel, making it perfect for applications where a non-reflective, textured surface is desired, such as in industrial equipment or automotive parts.

Tumbling

Tumbling smooths and polishes small parts through friction and abrasion in a rotating barrel, resulting in a consistent yet slightly textured finish. This process is perfect for achieving a uniform look on smaller components, making it ideal for applications like consumer electronics or medical devices where a smooth, polished surface with a subtle texture is desired.

Electropolish

Electropolish is a chemical process that smooths and brightens metal surfaces while enhancing corrosion resistance. This finish is perfect for improving both the durability and appearance of parts, making it ideal for applications in medical equipment, aerospace, or any industry requiring a polished, corrosion-resistant surface.

Alodine

Alodine coating provides excellent corrosion protection and improves paint adhesion, primarily used on aluminum surfaces. This finish is ideal for extending the lifespan of parts exposed to harsh environments, making it a great choice for applications in aerospace, automotive, and outdoor equipment.

Heat Treatment

Heat treatment alters the mechanical properties of metal, enhancing its hardness, strength, or ductility as needed. This process, conducted in a vacuum environment, ensures consistent results and is ideal for improving the performance of parts used in demanding applications like aerospace, automotive, and industrial equipment.

Brushed Finish

A brushed finish creates a unidirectional satin texture, minimizing the visibility of marks and scratches on the surface. This finish is perfect for achieving a sleek, professional look on metals like aluminum or steel, making it ideal for applications in consumer electronics, automotive components, or decorative parts where durability and aesthetics matter.

Powder Coating

Powder coating applies a thick, wear-resistant layer that offers excellent color and texture options, making it suitable for a variety of surfaces. This finish provides long-lasting protection and a vibrant look, ideal for parts in automotive, industrial equipment, or outdoor applications where durability and visual appeal are essential.

Electroplating

Electroplating bonds a thin layer of metal to a part, enhancing its wear resistance, corrosion resistance and surface conductivity. This shiny nickel coating is the perfect addition to a part's durability and appearance, making it ideal for applications such as electronics, automotive and industrial components where performance and a polished appearance are important.

Black Oxidize

Black oxidize is a conversion coating for ferrous metals that enhances corrosion resistance and reduces light reflection. This finish is ideal for steel components, providing a sleek, non-reflective black surface that’s perfect for applications in industrial equipment, automotive parts, or any project where durability and a low-glare finish are needed.

A No, we don’t enforce a minimum order quantity at Kaiao-RPRT. Whether you need a single prototype or thousands of parts, we’re ready to deliver. Our flexible approach ensures that clients of all sizes—from independent designers to large corporations—receive the same high-quality service and precision for their CNC machining projects.
Q How does KAIAO calculate the CNC machining cost for my project?

A Our engineering team reviews your 3D CAD files (.STP, .STEP, .IGS) to evaluate geometry complexity, setup time, and surface finishing. We provide a transparent CNC machining cost calculation breakdown with no hidden fees, helping you optimize part features to lower production expenses.
Q What materials and industries does your CNC machining factory support?

A Our facility operates 24/7, specializing in CNC milling and turning for medical, automotive, and aerospace parts. We machine a wide range of engineering materials, including aluminum, stainless steel, titanium, carbon fiber, and plastics such as ABS, PC, POM, and PEEK.
Q What tolerances can KAIAO's precision CNC machining handle?

A As a precision-driven CNC machining manufacturer, we strictly implement ISO quality standards. Depending on part geometry and material properties, we achieve standard machining tolerances of ±0.01mm to ±0.05mm. High-precision requirements can be evaluated upon file review.
Q What is the practical benefit of rapid CNC machining compared to 3D printing?

A While 3D printing is excellent for early-stage visual concepts, rapid CNC machining utilizes real block materials. This provides full mechanical strength, superior surface finishes, and precise thread tapping, making it the preferred choice for structural testing and functional validation.
