Surface finishes for machined parts

When it comes to CNC Milling parts, surface finish is crucial in choosing the right materials for your project. We at CNCFIRST provide various types of surface finishes for CNC Milling parts, from polished and sandblasted to anodized and chrome surfaces. Our experienced technicians can help you decide which surface finish best suits your specific needs, ensuring that the end product meets all quality standards.

as machined

as machined

The as machined is the standard surface finish for our parts. It removes sharp edges and clean removes burrs from the parts. The surface roughness of the machined part is 3.2 μ m (126 μ in).

anodizing parts


Anodizing is a process that can be used on CNC machined parts to enhance their performance, appearance and durability. It immerses the part in an electrolyte bath and applying an electric current which helps create a protective oxide film on its surface.

Black oxide parts

black oxide

Black oxide is also referred to as blackening, and it adds a matte black finish to the metal, making the surface look darker in contrast to its original state. It makes the CNC parts appear more aesthetically pleasing while also protecting it from corrosion and rusting.

polishing parts


The goal of polishing is to enhance the natural beauty of the material so that it looks better than when it was first created.

Our quality assurance

To guarantee the quality, we measure in place to maintain production standards and regulate the overall quality of CNC parts.

First, we carefully inspect raw materials before machining and during each production stage. This helps identify any defects or flaws that could potentially lead to product failure down the line.

Then, we conduct quality assurance tests during and after production, such as hardness testing, dimensional checks, pressure testing, visual examination, etc., to detect issues more easily throughout the process.

Other machining services

We have a wide range of CNC machines that can be used for various types of milling operations, from cutting and grinding metals to drilling and tapping. We also provide other machining services such as turning, wire EDM, and Swiss machining.

cnc turning services

With CNC turning, it can manipulate the material into its desired shape using cutting tools with great accuracy and consistency. Depending on the material’s thickness or the design’s complexity, we use different-sized tools.

Swiss machining

Swiss CNC machining is a highly precise machine that produces complex parts with tight tolerances. The Swiss CNC machine can handle multiple-axis movements that allow complex profiles to be cut accurately and quickly – typically in one operation.

wire EDM machining

Wire EDM erodes extremely hard metals, allowing for delicate and intricate designs to be etched into the material. It does not distort or warp the workpiece, so it is ideal for precision applications such as aerospace components, medical device parts, and injection molds.

CNC milling services FAQs

CNC milling is a process by which objects are created from various materials by machine.

The most common use for CNC mills is in manufacturing small parts and components, but they can also produce large pieces.

It is used in manufacturing to create parts for vehicles, appliances, medical equipment, aerospace applications, and more.

A CAD (Computer Aided Design) file is input into the CNC mill, which tells the machine where to cut the material.

The machine then moves around a rotating swivel table equipped with cutting tools, making meticulous cuts that hold together perfectly thanks to their precisely coordinated motion.

This method allows for extremely precise and intricate designs that would otherwise be difficult or impossible to create using other methods.

Some of the benefits of using CNC milling services include:

-Precision machining – With precision cutting tools, you can create parts with incredible accuracy and precision. This means that your parts will be durable and fit flawlessly together.

-Speed and efficiency – Thanks to our state-of-the-art machines, we can machine parts quickly and efficiently. You won’t have to wait long for your part(s) or suffer from low production rates due to slow machine speeds.

-Versatility – CNC milling is an adaptable process that can be used to machine a variety of parts and materials. You can count on our service to meet your specific needs and requirements.

-Low cost – CNC milling is often relatively cheap, unlike other precision machining services. This means that it’s an affordable option for high-quality parts production.

Choosing CNC machining services can be a great decision for your business. These services provide you with the ability to create high-quality parts quickly and easily, which can save you time and money.

Plus, CNC milling services offer various customization options that let you get exactly the look and feel you want for your products.

Generally speaking, CNC machined parts can be precision machined down to a tolerance of ± 0.0005 inches or better, depending on the material used and the size of the part being machined.

With this level of tight tolerance, we can produce complex shapes or geometries with high levels of accuracy while at the same time eliminating errors due to manual processes.

In addition, this process also allows for greater repeatability in terms of shape and dimensions when producing multiple pieces from a single design.

The cost of CNC milling can vary depending on the size and complexity of the project.

There are several factors to consider when calculating the cost of CNC machining: machine type and specs; cutting speed; the number of passes required; setup time; material requirements; surface finish desired; and shipping/installation costs.
