In centerless grinding, the workpiece is held between two grinding wheels, rotating in the same direction at different speeds.One grinding wheel is on a fixed axis and rotates so that the force applied to the workpiece is directed downward. This wheel usually performs the grinding action by having a higher linear speed than the workpiece at the point of contact.

UV light can safely be used for a variety of disinfection applications. Systems are available to disinfect rooms and high traffic areas with common touchpoints, ambulances and other emergency service vehicles, ductwork, tools or equipment inside a disinfection chamber, continuous pass-through conveyors, ...

Because for UV-bonded grind/lap the diamond particles are softly fixed by the cured-resin bond, the abrasive grains act in the grinding process at the beginning, causing more material removed. After a short time, then, some abrasives separate from the resin act as loose abrasives in the lapping operation and help to obtain a better work surface ...

In the EU, sunscreens are regulated as cosmetics with a permitted list of UV filters. TiO 2 was only considered a color and labeled as such with a CI number until 2000, when the EU Scientific Committee recommended that it be added as a UV filter up to 25%. This dealt mostly with micronized TiO 2. On April 15, 2002, this was incorporated into ...
