Ultrasonic vibration assisted micro end grinding (UAMEG) is a promising processing method for micro parts made of hard and brittle materials. First, the influence of ultrasonic assistance on the mechanism of this processing technology is theoretically analyzed. Then, in order to reveal the effects of ultrasonic vibration and grinding parameters on grinding forces and surface quality, …
Silica sand deposits, commonly quartz or derived from quartz, typically have a silica content of 95%; however, impurities may be present at up to 25%. Silica sand has been used for many different purposes over many years. In some instances, grinding of sand or gravel is required, increasing the levels of dust containing respira-

beads. Thus, tests indicated that silica beads were the most suitable grinding media due to the superior grinding performance along with a significant performance improvement when employing coarse beads. On the other hand, granular sand and fine silica beads were found inappropriate for ultra-fine grinding.
The ultra-precision grinding of fused silica in cross grinding modes has been carried out. Ultra-precision grinding is a very unique process requiring fine grained wheels, wear resistant abrasives, low run-out spindles and machine tools with a high loop stiffness.
The development of ultra-fine grinding at Anglo Platinum. THE DEVELOPMENT OF ULTRA FINE GRINDING 149 after maintenance) or foreign particles (either oversize silica or debris in the bund area, e.g. discarded bolts/nuts), causing damage to the rubber internals and the separator polyurethane parts.
As expected, L* values of ultra-fine samples increased and b* values decreased, probably due to a clean particle surface on which agitation can cause the occurrence of a new mineral surface. The results show that the dry grinding technique in conventional ball mills for gypsum ore can effectively obtain fine and ultra-fine products.

It is easy to obtain the near-polished grinding surface using fine-size grain diamond wheel (such as #2000, grain size 6.5 μm) and a small grinding depth. However, a relatively big-size wheel (such as #600, grain size 24 μm) is difficult to accomplish the near-polished grinding. Hence, this paper proposes a novel axis-feed grinding approach with the assistant of pure …
