Available surface finishes for CNC machining

Surface finishes are applied after machining and can change the appearance, surface roughness, hardness and chemical resistance of the produced parts.


                                                                      Name                                     Description



                                               This is our standard finish.

As machined (Ra 3.2μm /      Parts are machined and

 Ra 126μin)                            deburred, sharp edges are

                                               chamfered.




                                                                 

                                              Smooth machining is like an

  Smooth machining               ‘As machined’ finish but with

  (Ra 1.6μm /   Ra 63μin)        slightly less evident machine

                                               marks. Parts are machined at

                                               a lower feed, no hand polishing

                                               is applied.




                                                 Parts are bead blasted with      

 Bead Blasted                          glass beads which results in

                                                a grainy texture.





                                               Parts are brushed and then

                                               anodized type II. Ideal for

Brushed + Anodized               increasing the corrosion

type II (Glossy)                       resistance of the part.

                                               Typically results in a glossy

                                                color.




                                                                                                                                   Parts are bead blasted and

                                               anodized type II. Ideal for

                                               increasing the corrosion

Bead blasted +                       resistance of the part.

Anodized type II (Matte)         Results in naturally matte

                                               colors. For glossy colors,

                                               please select the brushed

                                               anodizing option.



                                               Parts are machined and an

                                               anodizing type III coating is

As machined +Anodized        directly applied to the

type III (Hardcoat)                  surface. Ideal to improve

                                               corrosion and wear

                                               resistance of components.



                                             

                                              Powder coating is a strong, 

                                              wear-resistant finish that is

Powder Coated                     compatible with all metal

                                              materials.




                                               Parts are brushed and                                           

 Brushed + Electropolished    electropolished. Ideal to

 (Ra 0.8μm / Ra 32μin)          reduce the micro-roughness

                                               of the part.




                                                    Applicable on steels, black

                                              oxide is a conversion coating

Black oxide                            used to improve corrosion

                                                     resistance and minimize light 

                                                     reflection.



                                                                                                                   Parts are machined and a

                                              chromate conversion coating

                                              is applied. Ideal to increase

Chromate conversion            the corrosion resistance of

coating                                  the part while maintaining its

                                                     conductive properties. RoHS

                                                     compliant.



                                                     Parts are brushed with a

Brushed (Ra 1.2μm /             #400 - 600 grit. Ideal to

Ra 47μin)                              reduce the surface

                                              roughness of the part.










                                                   Parts are manually polished

Polishing (Ra 0.8μm /          in multiple directions.

Ra 32μin)                             Surface is smooth and

                                             slightly reflective.
