In the US alone, the CNC machining industry is worth a lot. The global market is expected to reach $200 billion by 2025.
With numbers like that, it's no wonder why so many people are eager to get into the industry and learn about all aspects of CNC machining. This includes the different types of axes used in various projects.
There is a lot of talk these days about 4 and 5-axis CNC machining. But what's the difference? Which one would you like for your project?
In this blog post, we will take a closer look at both types of machining and help you decide which is right for you.

CNC Machining: What Is It and How Does It Work?
CNC machining is a manufacturing process in which computer-controlled machines remove material from a workpiece to create the desired shape. The process can be performed on various materials, including metals, plastics, and composites.
One of the most significant advantages of CNC machining is its ability to produce complex shapes that would be difficult or impossible to create with traditional methods. Additionally, CNC machining is relatively quick and efficient.
This flexibility in material usage makes CNC machining an ideal choice for many applications, even with five-axis CNC mill types.
4-Axis CNC Machining
4-axis CNC machining is a type of CNC machining that uses four axes of movement. The fourth axis is typically perpendicular to the other three (x, y, and z), allowing the cutting tool to rotate around the workpiece as it moves.
This type of machining is often used to create complex shapes or to machine multiple sides of a workpiece in one operation. In greater detail, 4-axis CNC machining can be used to:
- Create Complex Shapes: 4-axis CNC machining can create complex shapes that would be difficult or impossible to produce with traditional methods.
- Machine Multiple Sides: 4-axis CNC machining can machine multiple sides of a workpiece in one operation, which is ideal for mass production.
5-Axis CNC Machining: What's the Difference?
Adding a fifth axis to a CNC machine opens new possibilities for more complex machining projects. But what exactly is a fifth axis, and how does it differ from the standard three axes that most CNC machines have?
In simple terms, the fifth axis of a CNC machine allows for more degrees of freedom when machining an object.
This extra degree of freedom can be used to rotate the machined object around a certain point, allowing for more precise cuts and better overall results.
There are two main types of 5-axis CNC machines: those with a rotary table and those with a swivel head. Rotary table machines have a fifth axis built into the table, while swivel head machines have a fifth axis on the spindle.
5-axis CNC machining can be used for a variety of different projects, including:
- Machining complex shapes that would be impossible with a 3-axis machine
- Creating multi-sided objects such as cubes or pyramids
- Machining objects with irregular surfaces
- Carving intricate designs into objects
Adding a fifth axis to a CNC machine has some drawbacks, however. The most notable is the increased cost of the machine itself and the added complexity of programming it for use.
But the benefits outweigh the drawbacks for those who need the extra degree of freedom that a 5-axis machine offers.
Benefits of 4 and 5 Axis CNC Machining
There are many four-axis CNC benefits, as well as 5-axis CNC machining, including the ability to create complex shapes, machine multiple sides of a workpiece, and carve intricate designs. Additionally, CNC machining is relatively quick and efficient, making it ideal for mass production.
Four and 5-axis CNC machining offers many advantages over traditional manufacturing methods, making them the preferred choice for many applications. When deciding which type of machining is right for your project, consider the following factors:
- 4 and 5-axis CNC machining can create complex shapes that would be difficult or impossible to produce with traditional methods. CNC machining is likely your best option if you need to produce a shape that is significantly more complex than a simple cube or cylinder.
- 4-axis CNC machining can machine multiple sides of a workpiece in one operation, which is ideal for mass production. If you only need to machine one side of the workpiece, 3-axis machining may be sufficient.
- 5-axis CNC machining can be used to carve intricate designs into objects. If your project requires detailed and precise carving, 5-axis CNC machining is the best option.
Choose the machining method best suited for the material you are working with.
CNC machining is generally more expensive than traditional manufacturing methods. The cost of the machine itself, as well as the complexity of programming, can add to the overall expense.
However, the increased accuracy and precision of CNC machining may justify the added cost of your project.
Additional Considerations to Make for CNC Machining
No matter what type of CNC machining you're planning on doing, there are a few extra considerations to keep in mind. These include:
- Decide on the type of CNC machine that you need based on the project you're working on. For example, a 4-axis or 5-axis machine may be necessary if you need to machine complex shapes.
- Make sure that the CNC machine you choose is large enough to accommodate the size of your project.
- The Materials You're Working With: Choose the right type of CNC machine for the material you're working with. For example, if you're machining metal, you'll need a different machine than if you're machining plastic.
CNC machines can be expensive, so factor this into your budget. You may also need to factor in the cost of hiring someone to operate the machine.
CNC machining is a versatile and precise manufacturing process that can create various products. By understanding the different types of CNC machines and the applications they're best suited for, you can choose the right machine for your project.
So Which One Do You Need?
The type of CNC machining you need will depend on the complexity of the shapes you create and the number of sides you need to machine.
If you only need to create simple shapes or machine one side of an object, a 3-axis machine will suffice. But if you need to create complex shapes or machine multiple sides of an object, a 4- or 5-axis machine will be necessary.
