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 ...
IT and home appliance products processing: High-precision super-thin diamond cutting wheels are used to cut silicon slices. Resin-bonded diamond grinding wheels are used to process ceramics in optical fiber industry. Engineering ceramics processing: Engineering ceramics are widely used in many industries. They have the properties of high ...
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.
Synthetic diamonds are produced via high pressure, high temperature or chemical vapor deposition (CVD) technology. These diamonds have numerous industrial and commercial uses including cutting tools, thermal conductors and consumer diamond gemstones .
The term "mag wheels" became synonymous with die-cast wheels made from any material, from modern aluminium alloy wheels to plastic and composite wheels used on items like bicycles, wheelchairs, and skateboards. [4] [5] However, pure magnesium wheels are no longer produced, being found only on classic cars. Pure magnesium suffers from many problems.
Some discs used for cutting ceramic tile or stone are made from a solid disc with an edge coated with diamond grit. The most common size for these cutting wheels is 4 + 1 ⁄ 2 inches in diameter; however they can range from 2 to 16 inches in diameter with a thickness range from .045 in. to .125 in. Type 1 discs are flat, and type 27 discs have ...
However, those magnesium wheels proved to be impractical because they were prone to corrosion and they were mostly used in racing sports. After 1960's magnesium wheels were gradually replaced by aluminium alloy wheels on the mass market, but not from the competition wheels market. Many manufacturers of magnesium wheels are still operating.
Diamond turning is turning using a cutting tool with a diamond tip. It is a process of mechanical machining of precision elements using lathes or derivative machine tools (e.g., turn-mills, rotary transfers) equipped with natural or synthetic diamond-tipped tool bits .
