Abstract
A grinding wheel with fine abrasives is conventionally applied for precision grinding. In particular the precision grinding of brittle materials in the region of ductile mode chip removal is based on the fine abrasive with grain size of a few micron to sub-micron. This paper shows possibility of ultraprecision grinding with coarse abrasive wheel of grain size of over ten microns and also the precision grinding technology with coarse abrasive wheel can realize high productivity in precision riding of brittle materials. The key of the technology is dressing/truing of superabrasive wheel or control of height distribution of grain tops. The strategies on truing/dressing technique of superabrasive wheel is proposed and a example to be applied to technique is shown. The surface finish of 0.9 nm Ra is achieved for borosilicate glass ground with the metal bonded diamond wheel with number 800.
