Three axis four axis five axis CNC engraving machine between the difference

The china cnc router axis number of wood router machine woodworking cnc determines the type of work it can complete, the precision of cutting and the position of the workpiece that can be operated. So what are the differences between 3 axis, 4 axis and 5 axis cnc router auto tool changer?

Three-axis CNC router machine

Triaxial machining is the simplest and most common machining method. The workpiece is fixed in one position, and the spindle can move along X, Y and Z straight lines. That is, the motion mode of the three axes is X, Y and Z can move at the same time. The 3-axis machine is suitable for the parts with low requirements on depth and detail, and is used for plane engraving and plane plate cutting.

Four-axis 4 axis CNC router machine

4-axis machining involves the same process as 3-axis machining, except that the a-axis (positive or negative 110 degrees of deflection) is added to the vertical machining that the 3-axis machine can only do, using A cutting knife to remove material from the workpiece to create the desired shape and pattern. However, in the case of 4-axis machining, the milling knife is performed on the additional axis. A 4-axis CNC machine operates on X, Y, and Z axes like A 3-axis machine, but it also includes rotation around the X-axis, called the A-axis. The 4-axis machining is multi-functional and can be used to carve curved surfaces.

Five-axis CNC router machine

4-axis linkage means that in addition to the control of X, Y, Z three coordinate axes at the same time, but also control around these linear axis rotation of A, C coordinate axes, forming A simultaneous control of five axis linkage, then the knife can be set in any direction of the space.

4-axis machining requires more CNC programming preparation time to accommodate complex rotational motion, but allows one workpiece to be machined on all five faces in one operation. 5-axis machining is most effective when parts require a great deal of complexity and very high precision. This involves cutting complex details and machining complex shapes.
