XUDENG-Surface-finish-cnc-machined

→As machined
→Ra 3.2μm / Ra 126μin

→This is our standard finish. Parts are machined and deburred, sharp edges are chamfered.

XUDENG-Surface-finish-cnc-surface-smoothed

→Smooth machining
→Ra 1.6μm / Ra 63μin

→Smooth machining is like an ‘As machined’ finish but with slightly less evident machine marks. Parts are machined at a lower feed, no hand polishing is applied.

XUDENG-Surface-finish-powder-coated

→Powder Coated
→Ra N/A

→Powder coating is a strong, wear-resistant finish that is compatible with all metal materials.

XUDENG-Surface-finish-mirror-polish

→Mirror Polish
→Ra 0.1μm / Ra 3.94μin

→Powder coating is a strong, wear-resistant finish that is compatible with all metal materials.

XUDENG-Surface-finish-bead-blasting

→Bead Blasted
→Ra N/A

→Parts are bead blasted with glass beads which results in a grainy texture.

XUDENG-Surface-finish-Brushed-Anodized-glossy

→Brushed + Anodized type II
→(Glossy)

→Parts are brushed and then anodized type II. Ideal for increasing the corrosion resistance of the part. Typically results in a glossy color.
No Bead Blasted implemented.

XUDENG-Surface-finish-black-oxide

→Black oxide
→Ra N/A

→Black oxide is a conversion coating used to improve corrosion resistance and minimize light reflection.

XUDENG-Surface-finish-Electroless_Nickel_Plating_large

→Electroless nickel plating
→Ra N/A

→Electroless nickel plating can have a matte, semi-bright, or bright finish, For metal and plastic.

XUDENG-Surface-finish-brushed

→Brushed
→Ra 1.2μm / Ra 47μin

→Parts are brushed with a #400 – 600 grit. Ideal to reduce the surface roughness of the part.

XUDENG-Surface-finish-bead-blasted-anodized-matte

→Bead blasted + Anodized type II
→(Matte)

→Parts are bead blasted and anodized type II. 
Results in naturally matte colors. For glossy colors, please select the brushed anodizing option.

XUDENG-Surface-finish-brushed-electropolished

→Brushed + Electropolished
→Ra 0.8μm / Ra 32μin

→Parts are brushed and electropolished. Ideal to reduce the micro-roughness of the part.

XUDENG-Surface-finish-sproket-aluminum-brokenedge

→Sharp Edges
→Ra N/A

→Sharp Edges with visible toolmarks

XUDENG-Surface-finish-polishing

→Polishing
→Ra 0.8μm / Ra 32μin

→Parts are manually polished in multiple directions. Surface is smooth and slightly reflective.

XUDENG-Surface-finish-bead-blasted-anodized-matte

→As machined + Anodized type III
→(Hardcoat)

→Parts are machined and an anodizing type III coating is directly applied to the surface. Ideal to improve corrosion and wear resistance of components.

XUDENG-Surface-finish-chromate-conversion-coating

→Chromate conversion coating
→Ra N/A

→Parts are machined and a chromate conversion coating is applied.  RoHS compliant.

XUDENG-Surface-finish-sproket-aluminum-brokenedge

→Broken Edge
→Ra N/A

→Edges broken with visible toolmarks
