The 4-axis CNC router machine is based on the ordinary 3-axis CNC router machine and adds a fourth axis. It has two machine forms. One is a rotary axis CNC router machine with a fourth axis, which is also called a false 4 axis because it can only be linked with three axes at most; the other is a 4-axis CNC router machine with a swing head, which can perform four-axis linkage processing, also known as real 4-axis CNC router.After understanding this concept, you can choose the right 4-axis CNC machine according to your actual needs to bring the maximum benefit to your workshop. This article will introduce these two different types of 4-axis CNC router machines for your reference.
4 Axis CNC router machine with rotary axis
This 4-axis CNC router machine is based on the ordinary 3-axis router machine, adding a fourth axis, that is, the rotary axis. The fourth axis is a machine accessory that holds the workpiece on the chuck or between the two centers to rotate and position it. Due to the rotational motion of the fourth rotary axis, the CNC router machine can realize 3D machining of cylindrical surfaces and arc surfaces. In terms of use, it can machine planes, reliefs and cylinders.
Swing head 4 axis CNC router machine
The swing head 4-axis CNC router machine is a real four-axis CNC router machine, which can make all four axes of X, Y, Z and A work simultaneously. Accordingly, it is capable of sculpting various 3D items of regular, irregular, symmetrical and asymmetrical. A true 4-axis CNC router machine gives you more flexibility, it can engrave or mill cylindrical blanks at any angle from 0 degrees to 180 degrees.
