ADVANTAJES

Surface finish is a term that refers to the manufacturing process used to alter a metal’s surface in order to eliminate the imperfections left during machining process, to increase corrosion resistance, to improve resistance to chemicals, to increase strength and resistance to wear and to increase and to enhance aesthetics.

The range of post-processing and finishing methods that ROBOFACTURING3D offers will allow you to select the most suitable one depending on the end use of your part. The advantage of working with us is that you will receive everything from a single source and save the cumbersome task of commissioning several service providers, ensuring your parts are made right first time, every time.

SURFACE FINISHING FOR
MACHINED PARTS

STANDARD (AS MACHINED)

 estandard
– Surface roughness Ra = 3.2 μm (micrometres). Roughness ISO grade N8.

– Available to all metals and plastics.

It is our standard and quickest finish option. Tool marks are visible. Sharp edges and burrs are removed upon request. The colour of the finish will be the natural colour of the material.

IMPROVED MACHINED FINISH


– Surface roughness Ra = 1.6 μm (micrometres). Roughness ISO grade N7.
– Available to all metals and plastics.

The surface roughness will be improved during the CNC machining process itself by slower machining processes. Tool marks are visible, but less obvious. Sharp edges and burrs are removed upon request. The colour of the finish will be the natural colour of the material.

ANODIZING TYPE II OR DECORATIVE

ROB
– Corrosion-resistant finish.
– Masking requirements to be indicated in the technical drawings.
– Available to all aluminum materials.

The Type II anodizing process improves the aluminum properties increasing corrosion resistance and producing a uniform finish. ROBOFACTURING3D offers clear or black anodize coating, as well as it can be dyed in multiple colours (available upon request). Standard coating thickness 0,02 to 0,03 mm.

ANODIZING TYPE III OR HARDCOAT


– Corrosion-resistant and wear-resistant finish.
– Masking requirements to be indicated in the technical drawings.
Available to all aluminum materials.

The Type III anodizing process produces a thicker layer than Type II, adding a wear-resistant properties in addition to the previous corrosion-resistant indicated in Type II. You can find a clear or black anodize coating. Standard coating thickness 0,02 to 0,07 mm.

BEAD BLASTING


– Different grits depending on the size of the bead.
– Masking requirements to be indicated in the technical drawings.
– Available to all metals.

Bead blasting is often used in creating a smooth uniform matte or satin surface finish on machined parts. It is used mainly for visual appearance. Tool marks and sharp edges are removed. It is a very useful surface treatment on parts manufactured by die casting or to improve the surface finish of the part before applying a secondary surface finish, for example anodizing.

ELECTROPOLISHING

    
– Surface roughness Ra = 0.8 μm (micrometres). Roughness ISO grade N6.
– Improve the appearance and the corrosion resistance.
– Masking requirements to be indicated in the technical drawings.
– Available to all metals.

Electropolishing improves the appearance and the corrosion resistance by reducing the surface roughness. The colour of the finish will be the natural colour of the metal.

POWDER COATING


– Excellent corrosion-resistant and wear-resistant finish.
– Masking requirements to be indicated in the technical drawings.
– Available to all metals.

Powder coatings can produce much thicker coatings than conventional liquid coatings. Also, powder coated parts have fewer appearance differences than liquid coated parts between horizontally coated surfaces and vertically coated surfaces. Curing time is significantly faster with powder coatings. ROBOFACTURING3D offers a clear or black powder coating, but also can be finished in multiple colours (available upon request).

BRUSHING

 
– Surface roughness Ra = 0.8 μm to 1.6 μm (micrometres). Roughness ISO from grade N6 to grade N7.
– Polishing the metal to improve the appearance.
– Masking requirements to be indicated in the technical drawings.
– Available to all metals.

Brushing the metal will allow a satin finish. It allows to improve the surface roughness of the part but does not improve corrosion resistance since it does not modify the mechanical properties of the metal. The colour of the finish will be the natural colour of the metal.

CHEM FILM (CHROMATE CONVERSION COATING)


– Improve the corrosion resistance and maintain the conductivity properties.
– Masking requirements to be indicated in the technical drawings.
– Available to aluminum and alloys.

A chemical coating will be applied to the metal to improve the corrosion resistance. It can be used as a base for paint. The colour of the finish ROBOFACTURING3D offers is clear, yellow or golden.
