4 Axis Cnc Milling Machines

There are at least 4 coordinates on a four axis CNC milling machine, namely 3 linear coordinates and 1 rotational coordinate. Generally, an additional rotation axis is added on top of a three-axis machine tool. The characteristics of four-axis machining include: 1. The three-axis machine tool cannot process or requires too long clamping. 2. Improving the accuracy, quality, and efficiency of free space surfaces. 3. The difference between four axes and three axes. 4. The difference between four axes and three axes with one more rotation axis. The establishment of four axis coordinates and their code representation.
