Resumen de The rise of the superabrasives

Industrial Minerals

• .]US vehicle production fell by around 8% year-on-year in 2017 to 11.2 million units, according to statistics published by the International Organization of Motor Vehicle Manufacturers (OICA). [...]grinding wheels can quickly wear out and have to be replaced frequently. The G-ratios of conventional abrasives are usually in the 1-20 range, ceramics in the 10-200 range, while superabrasives are in the 500-10,000+ range, depending on the application. Because higher G-ratios typically equate to shorter grind cycles and more jobs per hour, grinding with superabrasives can increase productivity. According to the US Geological Survey (USGS), US abrasive mineral production in the first quarter of this year was flat compared with January-March 2017
