Finishes Options

As Machined Standard

Surface finish directly as a result of machining, without any post processing.

Surface roughness (Ra)	Machining marks	Deburring	Cosmetic
3.2 μm / 126 μin	Parts may have visible tool marks	Parts are deburred and sharp edges are chamfered	Some parts can have minor visual variations and cosmetic surface flaws

As Machined Medium

Surface finish is smoother than our standard finish, but no post processing is done.

Surface roughness (Ra)	Machining marks	Deburring	Cosmetic
1.6 μm / 63 μin	Parts may have lightly visible tool marks	Parts are deburred and sharp edges are chamfered	Some parts can have minor visual variations and cosmetic surface flaws

As Machined Fine

This is accomplished by using fine machining with high-quality cutting tools.

Surface roughness (Ra)	Machining marks	Deburring	Cosmetic
0.8 μm / 32 μin	Parts may have lightly visible tool marks	Parts are deburred and sharp edges are chamfered	Some parts can have minor visual variations and cosmetic surface flaws

Bead Blasting

Parts are glass-bead blasted, resulting in a textured, satin-like finish.

Machining marks	Deburring	Cosmetic	Tolerances
Machining marks are almost entirely removed	Parts are deburred and sharp edges are chamfered	Some parts can have minor visual variations and cosmetic surface flaws	Being a reductive finish, not suitable for parts with extremely tight tolerances

Brushed

Parts are manually brushed with sandpaper to improve surface roughness.

Surface roughness(Ra)	Machining marks	Deburring	Cosmetic	Tolerances
1.2 μm / 47 μin	Machining marks are almost entirely removed, except in areas that are physically inaccessible	Parts are deburred and sharp edges are chamfered	Some parts can have minor visual variations and cosmetic surface flaws	Being a reductive finish, not suitable for parts with extremely tight tolerances

Chromate Conversion Coating

Chromate Conversion Coating will be applied to parts with As Machined finish.

Machining marks	Deburring	Cosmetic	Tolerances
Machining marks will be visible per the As Machined finish prior to Chromate Conversion	Parts are deburred and sharp edges are chamfered	Some parts can have minor visual variations and cosmetic surface flaws	No effect on tolerances

Polishing

Parts are manually polished resulting in a smooth surface roughness.

Surface roughness (Ra)	Machining marks	Deburring
0.8 μm / 32 μin	Machining marks are almost entirely removed except places which are physically not accessible	Parts are deburred and sharp edges are chamfered

Powder coating

Economical, durable and long-lasting finish with many color options.

Machining marks	Deburring	Cosmetic	Tolerances
Machining marks will not be visible	Parts are deburred and sharp edges are chamfered	Some parts can have minor visual variations and cosmetic surface flaws	Coating thickness to be taken into account. Threads will be masked during the process

Black Oxide

Black Oxide coating is applied on As Machined parts to improve wear resistance.

Machining marks	Deburring	Cosmetic	Tolerances
Machining marks will be visible per the As Machined finish prior to Black Oxide Conversion	Parts are deburred and sharp edges are chamfered	Some parts can have minor visual variations and cosmetic surface flaws	Coating thickness to be taken into account. Thread masking as needed.

Electroless Plating

Electroless plating is applied to As Machined finish parts.

Machining marks	Deburring	Cosmetic	Tolerances
Machining marks will be visible per the As Machined finish prior to Black Oxide Conversion	Parts are deburred and sharp edges are chamfered	Some parts can have minor visual variations and cosmetic surface flaws	Coating thickness to be taken into account. Thread masking as needed.

Anodizing Type 2

Anodizing Type 2 is applied on As Machined parts to improve wear resistance.

Machining marks	Deburring	Cosmetic	Tolerances
Machining marks will be visible per the As Machined finish prior to Black Oxide Conversion	Parts are deburred and sharp edges are chamfered	Some parts can have minor visual variations and cosmetic surface flaws	Coating thickness to be taken into account. Thread masking as needed.

Anodizing Type 3

Anodizing Type 3 is applied on As Machined parts to form a highly durable coating.

Machining marks	Deburring	Cosmetic	Tolerances
Machining marks will be visible per the As Machined finish prior to Black Oxide Conversion	Parts are deburred and sharp edges are chamfered	Some parts can have minor visual variations and cosmetic surface flaws	Coating thickness to be taken into account. Thread masking as needed.
