Using diamond tools for the reduction of steel production in Micro

Using diamond tools for the reduction of steel production in Micro The diamond tool is commonly used in micro-machining, as it can withstand the microwave curing of the surface of the workpiece during the micro-machining. This micro-hardening creates enough resistance to breakage of the instrument easily in micro milling, but not a diamond. Micro-machining using diamond tools can be run at high speed and, in general, the speed of sound fine mirror surface finish, as the areas of high dimensional accuracy and non-ferrous alloys and abrasive non-metallic. However, if a diamond tool was used to cut steel, one of the most common engineering materials used in industry, diamond tool wear face serious. Although the diamonds to 1350 degrees softens and melts at 3027 degrees centigrade, and is also the most difficult in the material world, has a weak point. Diamond succumbs to graphitization, which means that it will change its crystalline structure of graphite crystal structure at 200 degrees Celsius in the presence of a catalyst metal such as carbon steel and titanium alloys, nickel and cobalt. There have been many attempts to improve the life of the tool steel, while the diamond cutting tool in order to improve efficiency and profitability of this operation. These processes include micro-cutting of carbon steel in a room full of gas chamber and a chamber cooling cryongenically. However, these changes require expensive equipment and restrict the direct supervision of micro-cutting process. The last step was when the diamond tool has been the subject of micro-vibration during cutting. E 'was shown that a diamond tool subject to ultrasonic vibrations reduces the steel sufficient to produce a surface finish with a mirror of life acceptable. Diamond tool edge ultrasound allows the tool to cool down significantly during the cutting process and delays the chemical reaction between the diamond tools and the piece of steel. Consequently, diamond, life is increased by several hundred times. For example, a single tool with the diamond crystal feed 5 micron / revolution, from zero to 5m/min cutting speed and depth of cut 10 micron was connected to a generator of ultrasonic vibrations to the point of diamond of about 4 microns and vibrato used to cut stainless steel. The surface to reduce the mirror surface of steel was measured at 8 nm Ra! With an increasing number of manufacturing companies moving in niche micro machining, such as using vibration cutting can only contribute to the progressive realization of innovative business processes, differentiation and leadership.
