| titleOfInvention | Method and apparatus for making grit and abrasive media |
| abstract | Synthetic diamond film produced by chemical vapor deposition can be crushed to obtain diamond grit which has useful abrasive properties. The flexibility of CVD deposition processes in determining diamond film properties means that CVD diamond grit properties can be tailored to particular abrasive applications. In a disclosed embodiment, the grit particles are coated with a magnetic material. The coated grit particles can then be aligned with a magnetic field, and the coated grit particles are bonded to a matrix while aligned. In a further disclosed form of the invention, a chemical vapor deposition system, such as an arc jet plasma deposition system, is provided in a chamber. A carrier strip and the deposition system are moved with respect to each other, and the deposition system is caused to deposit diamond film on the carrier strip. The strip can be of a flexible material, such as a copper or woven graphite material, and can be wound onto supply and take-up spools, respectively, before and after diamond deposition. Diamond film can be removed from the strip, such as by flexing the strip, and then crushed to obtain grit. The deposition system can also be utilized to produce other superabrasive grit, such as cBN, C3N4 or B22O. |
