INTRODUCTION:

A CNC router normally has a rigid z-axis where the drive motors control the motion of the z-axis to cut a part. But for processes like engraving : rigid Z-axis is unsuitable , as it wont accommodate variation in sheet height. The FLOATZ as the name suggests will float/glide on the sheet surface ( self-adjust to sheet surface) thus maintaining uniform engraving depth and also prevent tool jamming due to increased depth of cut. 

The FLOAT-Z does the reverse. It moves the tool on the z-axis freely whether it is a flat or a curved surface with varying depth without the z-axis drive motor controlling it.
