Abstract
In this paper, a practice to fabricate ultraviolet (UV) cured resin bond grinding wheels with abrasive grits in controllable 3-dimensional (3D) distributions was reported. The challenge in fabrication of resin-bonded grinding wheels with controllable abrasive girts distribution is to simultaneously cure heterogeneous materials with suitable slice thickness and sufficient bonding strength between cured layers. This is beyond the capability of most commercially available 3D printers. A new Stereolithography Apparatus equipment with automatic functions of resin applying, grits planting, resin curing and wheel lifting was developed. Successively, multi-layered abrasive wheels were fabricated by planting abrasive grits and UV curing resin layer-by-layer. In doing so, 3D grinding wheel with controllable abrasive girts distribution were fabricated. Finally, the grinding performance and wear characteristics of newly developed grinding wheels were revealed through the grinding experiments. The results indicated that the distribution of diamond abrasive grits plays a determining role in the wear behavior, and hence the grinding performance of resin grinding wheels has been greatly improved.
