Introduction
The surface finish of a part or component is often one of the most important aspects of its overall appearance and performance. The level of detail that can be achieved with today’s CNC machining technology means that many manufacturers can produce incredibly high-quality products by ensuring they maintain an excellent surface finish at all times.
Achieving a perfect CNC machined surface finish on a part or component can be a key competitive advantage for many manufacturers and machine shops.
Achieving a perfect CNC cutting machined surface finish on a part or component can be a key competitive advantage for many manufacturers and machine shops. In some industries, such as aerospace, medical devices, and others that require high levels of precision, machined parts are often used in critical applications where even minor deviations from the design specifications can result in severe consequences.
For example, if an airplane fuselage is produced with too much variation in its thickness measurements (from point to point) then it won’t fit properly during flight while carrying passengers and cargo. Medical equipment like artificial hips made with metal alloys could experience faster wear and tear due to irregular surfaces or edges caused by improper tooling setups (such as incorrect tool holders).
Machined components that stand up well under pressure need to have an excellent finish due to their proximity with other elements within the system they work within; any imperfections may lead to increased friction between two surfaces which reduces performance over time due to increased wear rates on both parts involved (the mating surface as well as the material being machined).
Often, such a perfect surface finish is not only necessary from an aesthetic standpoint, but also from a functional perspective when creating parts with critical performance requirements.
For many applications, such a perfect surface finish is not only necessary from an aesthetic standpoint, but also from a functional perspective when creating parts with critical performance requirements. For example, in the aerospace industry and other industries where corrosion resistance is important, it’s often necessary to use a surface finish that will resist wear and tear and prevent corrosion over time.
Whether your project requires you to use CNC machining or any other type of manufacturing method (including manual methods), it’s essential to choose the right finishing technique so that you can create the best possible product. There are many different types of finishes available for this purpose—some more durable than others—and choosing one depends on what kind of job you need to be done.
The most common types include:
- Brushed
- Sandblasted
Powder coating
Powder coating is a type of paint that is applied to a surface. Industrial powder coating has become the most common type of finish for CNC machined parts because it provides both corrosion resistance and color variety.
In addition, powder coating can be used on any metal part and is especially effective on parts that require a high degree of corrosion resistance.
In this guide, we will take you through some of the most common types of surface finishes that are applied to CNC machined parts in 2021.

Powder coating is a process that uses electrostatic attraction to coat an object with a thin layer of powder. It can be used on both ferrous and nonferrous materials and is often sprayed onto components using high-pressure air guns. This method creates a strong bond between the part and its coating—which means it won’t flake off like paint or other forms of paint-like coatings do. In addition, powders offer more flexibility than liquid paints because they can be applied at room temperature without any additives or solvents needed (such as water).
Find out what type of surface finish you can achieve with CNC machining!
CNC machining is a process that uses computer-controlled machinery to cut, shape and form parts. It can be used for several different applications, including 3D printing, mold making, and prototyping.
To create an accurate surface finish on your CNC machine part, you need to know what kind of surface finish it’s capable of achieving. There are three main types of surface finishes that CNC machines are capable of producing:
- Raised (aka “positive”)
- Flat or low relief (aka “negative”)
- Rough machined
