The cutting edge of most diamond tools is sharp to tens of nanometers, making it very effective for cutting non-ferrous materials with high resolution. SPDT is a very accurate machining process, used to create finished aspherical and irregular optics without the need for further polishing after completion.
The first major development in diamond cutting came with the "Point Cut" during the later half of the 14th century: the Point Cut follows the natural shape of an octahedral rough diamond crystal, [2] eliminating some waste in the cutting process. Diamond cutting, as well as overall processing, is concentrated in a few cities around the world ...
Google Maps' location tracking is regarded by some as a threat to users' privacy, with Dylan Tweney of VentureBeat writing in August 2014 that "Google is probably logging your location, step by step, via Google Maps", and linked users to Google's location history map, which "lets you see the path you've traced for any given day that your ...
There are two common methods to manufacture diamond grinding cup wheels: hot pressing and cold pressing. The hot pressing method is to directly sinter the diamond segments in molds under a certain pressure in the dedicated sintering press machine, and then fix or connect the diamond segments onto the grinding wheel’s body via high-frequency welding, laser welding or mechanical mosaic method.
A gemcutter polishes stone, using felt or canvas-covered polishing wheel, and polishing compounds, such as tripoli or jeweler's rouge. Possibly using a mechanical facet-cutting device. A gemcutter may cut and polish diamonds for industrial purposes, and be designated as an Industrial-Diamond Polisher.
Veronica Brown lived with chronic fatigue, depression, and anxiety for over 10 years before she learned they were early signs of Parkinson's disease. Here's how she found relief after diagnosis.
Federal prosecutors announced Tuesday that a New York tax preparer known as 'the Magician" pled guilty to filing thousands of false tax returns.
The diamond segments are also known as the "cutting teeth" of the blade. [2] The steel core can vary in design. Some cores have spaces (known as gullets) between segments to provide cooling and slurry removal, while others have a single continuous rim for smoother cutting. The type of core that can be used depends on the type of materials that ...
