We all know that CNC machining center plays a very important role in CNC machining. So, do you know what are the differences between 3 axis, 4 axis and 5 axis? What are the advantages of each of them? And what products are they suitable for? Let’s see in this paper.

Three-Axis CNC Machining Center

It usually refers to three axes moving in a straight line in different directions, such as up and down, front and back, and left and right. Three axis can only process one surface at a time, suitable for processing some plane and disk parts.

Four-Axis CNC Machining Center

Four-axis is to add A rotation axis on the basis of the three-axis, that is, to process objects on the four degrees of freedom of displacement X, Y, Z and A. When the workpiece is not located in space, there are six degrees of freedom, X, Y, Z three linear displacement degrees and its corresponding A, B, C three rotational displacement degrees. But it can not be at high speed. It is suitable for processing some box parts. As a representative production equipment of mechanized large-scale production, four-axis machining center plays a significant role in the daily production and manufacturing process for enterprises.

Five-Axis CNC Machining Center

Five axis machining center has two kinds of rotation. One is the rotating axis of the workbench, the workpiece can be divided into any Angle processing, can process inclined plane and inclined hole, choose high-end CNC five-axis system and software RETP support, but also can process complex space surface. This type of five axis machining center advantage is the spindle structure is simple, rigid. One disadvantage is that it has a relatively small load bearing capacity.

Another rotation is the spindle swing head rotation, spindle front is a rotary head design, the advantages of this device in processing with the spindle can be very flexible, workbench can be put load heavy, this kind of design of five axis swing head has an advantage, the use of spherical milling surface processing, Tool center line and machining surface vertical plane using spindle rotation can effectively avoid vertex cutting, can ensure linear speed, but also improve the surface processing quality, this structure is used for the mold surface requirements of higher precision more selection. In order to achieve more precise rotary accuracy requirements, also can be equipped with a grating ruler. The accuracy can reach μm level. It is suitable for box type parts, complex surface type parts, special-shaped type parts and so on.

In Conclusion

Although compared to four axis and three axis, five axis has very prominent advantages. However, not all products are suitable for five axis processing. Maybe products that are suitable for three axis processing are not suitable for five axis processing. If you apply five axis processing for products that three axis can be processed, it will not only increase the cost, the effect is not good either. Therefore, you have to arrange suitable machining centers for your products, the machine can play a valuable role.
