CNC Turning Surface Finishes
DakingsRapid offers a wide range of surface finishes for precision CNC turning parts to help enhance product performance and appearance. Surface treatments for CNC turning parts improve aesthetics, surface hardness, wear resistance, and chemical corrosion resistance. Additionally, they can enhance visibility in functional or power transmission applications. Below is a selection of our surface finishing processes.
As Machined
The surface directly after CNC machining shows the raw machining marks. It is a low-cost and efficient choice while retaining visible tool marks.
Anodizing
Anodizing improves wear and corrosion resistance. It also allows for coloring, making it an ideal choice for aluminum CNC turned parts.
Polishing
Polishing achieves a high-gloss surface and reduces surface roughness, enhancing the aesthetic appeal of precision metal components.
Bead Blasting
Bead blasting uses sand or other media to clean the surface and remove burrs, resulting in a uniform matte finish.
Tumbling
Tumbling uses friction and abrasion inside a drum to smooth small parts and remove burrs, achieving a uniform and textured surface.
Electropolishing
Electropolishing is a chemical process that smooths and brightens the surface while improving corrosion resistance.
Brushed Finish
Brushing creates a unidirectional texture on the surface, reducing the visibility of surface imperfections and scratches.
Powder Coating
Powder coating forms a wear-resistant and weather-resistant layer, available in a wide range of colors and textures for various surfaces.
Electroplating
Electroplating forms a thin metal layer on the part, improving wear resistance, corrosion resistance, and aesthetics.
Black Oxide
Black oxide is a conversion coating for ferrous metals that improves wear resistance and provides a black or dark grey appearance.
Alodine
Alodine coating provides corrosion protection and improves paint adhesion, primarily used for aluminum alloys.
Heat Treatment
Heat treatment alters the mechanical properties of the metal, thereby increasing hardness, strength, or ductility for demanding manufacturing applications.
Tolerances for
CNC Turning
As an ISO 9001 certified CNC turning factory, we machine high-precision CNC turning parts to meet strict tolerance requirements. Based on your design specifications, our CNC lathes can achieve tolerances of up to ±0.005″. Our standard tolerances for machined metals follow ISO 2768-m, while plastics comply with ISO 2768-c, ensuring consistent quality for both prototype and production manufacturing projects.
| Specification | Detail |
|---|---|
| Maximum Part Size | Typically up to 500 mm in diameter and 1500 mm in length, though larger sizes can be accommodated with specific equipment. |
| Minimum Part Size | As small as 1 mm in diameter, depending on the material and machining setup. |
| General Tolerances | Standard tolerances of ±0.01-0.05 mm; tighter tolerances down to ±0.005 mm can be achieved based on the material and complexity of the part. |
| Lead Time | Standard lead times range from 4-7 days for small batches. Expedited services are available, reducing lead time to 24-48 hours. |
