Our standard surface finishes

As machined

Our standard finish is “as machined” finish. It has a surface roughness of 3.2 μm (126 μin). All sharp edges are removed and parts are deburred. Tool marks are visible.

Smoothing

A finishing CNC machining operation can be applied to the part to reduce its surface roughness. The standard smoothing surface roughness (Ra) is 1.6 μm (63 μin). This can be decreased down to 0.4 μm (15.7 μin) upon request and on a case-by-case basis. Machine marks are less evident but still visible.

Anodizing color or clear (type II)

Type II anodizing is mainly used to produce parts with a uniform, aesthetically pleasing surface and provides good corrosion and limited wear resistance.

Requirement	Specification
Thickness	8 - 12 μm (clear), 4 - 8 μm (color)
Color	Black, clear or any RAL code or Pantone number
Part masking	Indicate masking requirements in technical drawing

Anodizing hardcoat (type III)

Type III anodizing provides excellent corrosion and wear resistance, suitable for functional applications.

Requirement	Specification
Thickness	50 - 125 μm
Color	Black or clear
Part masking	Indicate masking requirements in technical drawing

Bead blasting

Bead blasting adds a uniform matte or satin surface finish on a machined part, removing the tool marks. This is used mainly for visual purposes and comes in several different grits which indicate the size of the bombarding pellets.

Requirement	Specification
Grit	#100, #120 and #150
Color	Uniform matte of raw material color
Part masking	Indicate masking requirements in technical drawing

Powder coating

Powder coating is a strong, wear-resistant finish that is compatible with all metal materials and can be combined with a bead blasting to create parts with smooth and uniform surfaces and excellent corrosion resistance.

Requirement	Specification
Thickness	18 - 72μm
Color	Black or any RAL code or Pantone number.
Part masking	Indicate masking requirements in technical drawing.

Electropolishing

Electropolishing is an electrochemical process used to polish, passivate and deburr metal parts. It is useful to reduce surface roughness.

Requirement	Specification
Color	Natural metal color.
Part masking	Indicate masking requirements in technical drawing.

Black oxide

Black oxide is a conversion coating used to improve corrosion resistance and minimize light reflection.

Requirement	Specification
Color	Black
Part masking	Indicate masking requirements in technical drawing.

Brushing

Brushing is produced by polishing the metal with grit resulting in a unidirectional satin finish. Not advisable for applications where corrosion resistance is required.

Requirement	Specification
Surface roughness	0.8 - 1.5 μm
Grit	#80-120
Part masking	Indicate masking requirements in technical drawing.

What are surface finishing operations

Surface finishing operations are a manufacturing process used to improve the appearance and function of a product's surface. There are many different methods of surface finishing operations. Still, some of the most common include polishing, buffing, sanding, and grinding.

What is surface finishing in engineering

In engineering, surface finishing is bringing a surface to the required shape and finish. The finishing processes depend on the type of material being completed, its intended use, and the manufacturing process used to produce it.

Why do we need surface finishing

There are a few reasons surface finishing is essential. First, it can improve the aesthetics of a product. This is important for products that will be used in public or seen by others. Second, surface finishing can also protect the underlying material from damage. This is especially important for metals, which can be susceptible to corrosion and other types of damage if left unprotected. Finally, surface finishing can also improve the functionality of a product. For example, saw blades and other cutting tools are often given a special coating to help them resist wear and tear.
