The router with 4th axis is a real marvel of technology, allowing some really amazing cnc router adjustments. These are the things that make this tool so useful and interesting
First, it allows you to make very precise adjustments on the X-axis (the Y-axis and Z-axis are fixed). This allows you to cut holes in your work piece with the same accuracy as if you were using a hand drill
Second, it can be used to move the X-axis along an arc. This means that you can cut circles, arcs, and other shapes without having to move the whole table assembly around. It also allows for really smooth movements across large surfaces
Thirdly, it has an incredible range of rotation angles available – from full 360 degrees up to 270 degrees (!), allowing for much greater versatility than most any other tool out there!
