What is CNC Milling

What is CNC Milling?

CNC milling is a manufacturing process used to produce custom-designed parts from various materials such as aluminum, steel, and plastics. The process employs computer-controlled machines to create complex parts that are difficult to produce using traditional machining techniques. CNC milling machines are operated by computer software that controls the movement of cutting tools, enabling them to remove material from a workpiece to create the desired shape and size.


CNC milling offers several advantages over traditional milling methods. It is faster, more precise, and capable of producing complex geometries that are difficult to create using manual or conventional machines. The use of computer-aided design (CAD) software allows designers to create highly detailed models of parts that can be easily translated into machine code for the CNC milling machine to follow.

CNC milling machines are highly versatile and can be used to produce a wide range of parts, from simple brackets to complex components for aerospace and medical applications. They can be used to produce parts in small quantities, as well as large-scale production runs.

How CNC Milling Works

CNC milling works by using computer-controlled machines to remove material from a workpiece to create a specific shape or design. The process involves a range of cutting tools that are used to remove material from the workpiece to create the desired shape and size.

The CNC milling machine is operated by computer software that controls the movement of the cutting tools. The software reads the design specifications of the part and translates them into machine code that the CNC milling machine follows. The cutting tools move along multiple axes, allowing them to produce complex geometries and shapes.

The CNC milling process can be used to create parts from a variety of materials, including aluminum, steel, and plastics. The process is highly accurate and capable of producing parts with tight tolerances, making it ideal for the production of complex components for aerospace and medical applications.

Types of CNC Mills

The most widely used type of CNC milling machine. The full use of the X, Y, and Z directions makes a 3 Axis CNC mill useful for a wide variety of work.
This type of router allows the machine to rotate on a vertical axis, moving the workpiece to introduce more continuous machining.
These machines have three traditional axes as well as two additional rotary axes. A 5-axis CNC router is, therefore, able to machine 5 sides of a workpiece at in one machine without having to remove the workpiece and reset. The workpiece rotates, and the spindle head is able to also move around the piece. These are larger and more expensive.

Types of CNC Mills

There are several surface treatments that can be used for CNC machined aluminum parts. The type of treatment used will depend on the specific requirements of the part and the desired finish. Here are some common surface treatments for CNC machined aluminum parts:

Other Benefits Of CNC Mill Machining Processes

CNC milling machines are built for precise manufacturing and repeatability which makes them perfect for rapid prototyping and low-to-high volume production runs. CNC mills can also work with a variety of materials from basic aluminum and plastics to more exotic ones like titanium — making them the ideal machine for almost any job.
