Finishes Options

As Machined Standard

	Surface roughness (Ra)	Machining marks	Deburring	Cosmetic
Surface finish directly as a result of machining, without any post processing.	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 roughness (Ra)	Machining marks	Deburring	Cosmetic
Surface finish is smoother than our standard finish, but no post processing is done.	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

	Surface roughness (Ra)	Machining marks	Deburring	Cosmetic
This is accomplished by using fine machining with high-quality cutting tools.	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

Thread masking as needed.

Bead Blasting

	Machining marks	Deburring	Cosmetic	Tolerances
Parts are glass-bead blasted, resulting in a textured, satin-like finish.	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

	Surface roughness(Ra)	Machining marks	Deburring	Cosmetic	Tolerances
Parts are manually brushed with sandpaper to improve surface roughness.	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

	Machining marks	Deburring	Cosmetic	Tolerances
Chromate Conversion Coating will be applied to parts with As Machined finish.	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

Electroless Plating

	Machining marks	Deburring	Cosmetic	Tolerances
Electroless plating is applied to As Machined finish parts.	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.

Electroplating
