The dressing technology of metal bonded diamond tools has always been its research focus. Scholars from all over the world have developed a new dressing technology for metal-based diamond grinding wheels. The main dressing methods are as follows:
Common Grinding Wheel Dressing Methods
Electrolytic In-process Dressing (ELID)
In 1985, Murata first put forward the technology of electrolytic in-process dressing (ELID), and used a metal bond wheel with the grain size of 400# to grind hard and brittle materials such as ceramics. In 1990, OHMORI of Japan Institute of Physical Chemistry successfully solved the problem of sharpening cast iron-based grinding wheels by using ELID and used ELID to make ultra-fine diamond grinding wheels (with a particle size of several microns to 5nm) used for mirror grinding of hard and brittle materials. Islam et al. conducted an on-line dressing experiment with a cast iron metal bond diamond wheel with a particle size of 8000 mesh and studied the influence of current on grinding performance. In addition, researchers from many universities and research institutions in China, such as Harbin Institute of Technology, Northwestern Polytechnical University, Hunan University, and Tianjin University, have conducted extensive and in-depth research on online electrolytic finishing technology, which has promoted the application of online electrolytic finishing technology in ceramics, optical glass, aerospace, and other fields.
