Recognition of burr degradation mechanisms will be a starting point for further research leading to procedure optimization and increasing its safety and efficacy - speed of removing the calcified or fibrotic plaques. For this purpose, rotablation burrs (new ones and used) were examined. 2. …
The grinding performance of unidirectional carbon fibre reinforced silicon carbide ceramic matrix composites (Cf/SiC) was investigated in this paper. The effects of the fibre orientation and grinding depth on the surface integrity and grinding forces and an understanding of the grinding mechanisms are the primary concerns of this article.
Grinding, an essential procedure for size reduction and fresh surface exposure of mineral particles, plays an important role in mineral flotation. The grinding media are the key factors for effective grinding and thus for successful flotation. In this study, ceramic ball (CB) and cast iron ball (CIB), two representative grinding media, were chosen to investigate the effects and mechanisms of ...
Grinding is one of the essential manufacturing processes for producing brittle or hard materials-based precision parts (e.g., optical lenses). In grinding, a grinding …
although there is a gap in understanding GA effectiveness mechanism on the flow properties. The present study aims to fill this gap using different GAs (Zalta™ GR20-587, Zalta™ VM1122, and sodium hydroxide) through batch grinding experiments of magnetite ore and addressing the mechanisms of their effects on
Mineral grinding oil was used as cooling lubricant. In order to emphasize the fundamental chip formation mechanisms and their change along the engagement zone of the tool, the grinding tool and process parameters were deliberately chosen to achieve high average single grain thicknesses h cu,av.Therefore, a cutting speed of v c = 5 m/s, a feed-rate of v ft = 80 mm/min and a cutting depth of …
