CNC Machining Surface Finishes

SOMI offers a diverse range of surface finishes, each tailored to meet the specific needs of your projects. Here’s a closer look at some of the options

Metals
Plastics

As-machined
The standard finish of our parts, the "machined" finish, has a surface roughness of 3.2 μm (126 μin), which removes sharp edges and cleanly removes burrs from the part.
Machining Texture:There are slight scratches on the visible surface.
Smooth machining
A finishing CNC machining operation can be applied to the part to reduce its surface roughness. The standard smoothing surface roughness is Ra 1.6 μm (64 μin). Light surface scratches are visible.
Machining Texture:Visible, light surface scratches.
Fine machining
Refers to the process of precision treatment of raw materials or semi-finished products. The standard smoothing surface roughness is Ra 0.8 μm (32 μin).
Machining Texture:Slightly visible.
Bead blasting
Bead blasting refers to the use of round spherical media that, when impacted against the surface of a part, will leave a more uniform finish caused by the sphere “dimpling” the surface.
Machining Texture:Frosted grain.
Brushing
Brushing is a surface treatment process that uses abrasive belts to draw traces on the surface of a material, usually for aesthetic purposes.
Polishing
From Ra 0.8 to Ra0.1, the polishing process uses abrasive materials to rub the surface of the part, making the surface of the part more shiny, depending on your requirements.
Machining Texture:Smooth, glossy finish
Anodizing
Aluminum and its alloy in the corresponding electrolyte and specific process conditions, due to the action of external current, the process of forming an oxide film on the aluminum product.
Machining Texture:Smooth, matte finish.
Electroplating
Electroplated coating preserves the surface of parts and resists rusts and other defects from causing decay by applying electric currents to reduce metal cations.
Machining Texture:Smooth, glossy finish.
Electroless nickel plating
Electroless nickel plating is a process that deposits an alloy of nickel-phosphorus onto the surface of a metal. This process is chemical only, so does not involve the use of electricity.
Machining Texture:Reduced but visible.
Black oxide
Black oxide is a conversion coating similar to Alodine that is used for steel and stainless steel. It is used mainly for appearance and for mild corrosion resistance..
Machining Texture:Smooth, matte.
Powder coating
Using corona discharge, we make the powder coating adsorbed to the part, creating a more wear-resistant layer with a typical thickness ranging from 50 μm up to 150 μm.
Machining Texture:Glossy.
Chromate conversion coating
Chromate conversion coating is a type of conversion coating, used on aluminum as a corrosion inhibitor, as a primer for paint due to increased adherence or to preserve electrical conductivity.
Machining Texture:Visible.
Electrophoresis
In the solution under the action of direct current electric field, the charged resin moves to the opposite electrode phenomenon. Strong corrosion resistance, can be on different colors.
Machining Texture:Visible.
