The state of the wheel surface after dressing is important for processing of a surface to
the nano-order level. A laser dresser was developed using ultraviolet (UV) laser light, which
imparts no mechanical damage to the resin bond. One feature of this system is that UV laser energy
is transmitted by a special optical fiber for UV light, and is transmitted only to the resin bond. Using
this newly developed laser dresser, it was possible to ablate the resin bond to a depth of over 2
microns using a fiber with a core diameter of 200 microns.
