Difference between 3 Axis and 5 Axis Machining

Last Updated on April 29, 2022 by Leizi

CNC(computer numerical control) machining is always one of the top-list choices for most companies to create high-precision prototypes. It produces the plastic and metal components by cutting the lumpy materials into the parts of a specific size. At the same time, there are multi-axis CNC machining methods on the market including 3 and 5-axis machining. You might have trouble telling the difference between them If you don’t know much about the processing industry. Let’s see what the differences are!

What is 3-axis machining?

Many machining services providers generally purchase 3-axis CNC machining machines as basic equipment. Compared to 5 axis machines, the cost of 3 axis CNC machining machines are comparatively economical.

During CNC machining, the professional operators will input the edited program into the computer and the 3-axis CNC machining machines would automatically run according to the programms. The CNC machining cutters would cut the materials along with the X, Y, and Z-axis while the lumpy material is fixed in one single position. It can only cut one side of the materials each time. That’s why 3-axis machining is more suitable to machine the parts of geometries and simple structures.

What is 5-axis machining?

As the name of the machine says, 5-axis machining machines run along with the axis of X, Y, Z, A, and B. It means that we do not need to remove the fixtures manually. Instead, the operators can operate the machines to cut the lumpy materials directly. It can save much time to create the components with more complicated design and tight tolerance. That’s why 5-axis machining is among the industries of aerospace and automotive, which have more requirements for precision.

The main differences between 3 axis machining and 5 axis machining:

(1). The quantity of axis used. The former one uses a 3 axis to work through the machining process. The latter one applies 5 axes to machine the materials.

(2). The total cost. If you get not have much budget to buy the CNC machines, 3 axis CNC machines would more economical and functional for you.

(3).The tolerance of 3-axis and 5-axis CNC machines. The latter can create parts of more tight tolerance.

Now, do you see the difference between the two? At Ruitai, we are capable of offering you 3-axis and 5-axis machining services. If you are any CNC machining guidance, Ruitai is always glad to support you.
