Field of use of diamond tools

Diamond is the hardest, so in stone, building materials processing, diamond cutting tool is a good tool. Diamond tools such as diamond saw blades and wear-resistant materials in non-ferrous metal processing applications, has excellent adaptability. Use the following detailed description of the field of diamond tools.
When using diamond tools, users  concrete diamond blades have two options: one is polycrystalline diamond (PCD), the other is a relatively new chemical vapor deposition (CVD) diamond.
Early use of proven performance
Polycrystalline diamond has a natural diamond hardness, strength and abrasion resistance, but does not damage the sensitivity of natural diamond. It is at high temperature, the polymerization of the synthetic diamond particles. In the process, while the polycrystalline particles is integrally formed is bonded to a cemented carbide substrate on to improve the mechanical strength and impact resistance.
PCD is applicable to high-speed cutting of aluminum, is particularly suitable is required to achieve good surface roughness of the main case, it is in the processing of high wear resistance, and exhibits excellent performance. Typically, PCD recommended for cutting high silicon aluminum alloy, but also for brass, copper, bronze, and carbide processing. Processes used include turning, boring, profiling, grooving, milling and hole processing.
As the chemical reaction between the diamond and iron, in general, does not apply to the processing of ferrous metals PCD material. However, it can deal with the processing of bi-metal material, comprising a combination of aluminum and iron included. For example: a car parts suppliers in the processing of aluminum and cast iron cylinder bi-metal body with a diameter of 305mm wafer type face milling cutter, corner radius 2.36mm, with repair knife, cutting 304.8m/min, feed 0.10 mm / tooth, depth of cut 5mm, processing up to the 5000 cylinder block, indexable inserts only need one.
By the mass production industry, primarily grinding cup wheels  in the automotive industry increasing push aluminum processing speeds. Meanwhile, car manufacturers in order to reduce weight and reduce costs, is on the use of metal matrix composites evaluated, and such materials must be processed by PCD. He said: "Such material can not be processed using carbide tools."
Polycrystalline product manager, said that although the PCD development achievements have been giving a very deep impression,
PCD tools in terms of scope and production efficiency, have brought many benefits to the process. Although the diamond is the hardest available materials, the material characteristics and toughness problems still further. One factor to improve the toughness of PCD is plus cobalt is not directed it into a random arrangement between the diamond grains. Further, the cemented carbide substrate of the diamond abrasive layer can also act as a mechanical support, thereby increasing the impact resistance, and ease of manufacture of brazed tool.
Another benefit of the PCD, the existing series of various grades have been able to meet any need to use non-ferrous metal processing. In general, the fine particles are less wear diamond for materials processing require very high surface roughness of the occasion; diamond  sand paper particles in general as generic brands machining; coarse diamond for roughing the special anti-wear material, but the surface roughness of less demanding place.
Bright future
At present, many production sites do not take full advantage of the diamond. The reason is that a lot of speed and torque tools are not sufficient to ensure the efficient functioning of the tool.
In addition to mechanical problems, there is a difficult problem is to convince people to produce the factory, do not just stare at diamond (PCD or CVD diamond) set the initial price, but to see it brings cost savings and improved performance benefits. You can make a diamond tool than conventional operation (depending on machine performance may be) at a higher speed, thereby enhancing the volume of output. Meanwhile, fewer tool changes. Assume diamond carbide than 50 times to 100 times higher life, you do not often stop it.
