Polycrystalline diamond (PCD) Tools Processing of aluminum parts with a long tool life and metal removal rate advantages, the drawback is the expensive tools, high processing costs. This point Machinery Manufacturing industry has formed a consensus. PCD cutting tools in recent years the development and application of many changes have occurred. Today, the performance of aluminum material has shrunk, the new development in the processing of aluminum alloy materials (especially high silicon content of composite materials), in order to achieve productivity and quality optimization process must be carefully chosen PCD tool grade and geometry parameters to meet different processing requirements. Another change is the PCD cutting tools continue to lower processing costs, competitive pressures in the market, improved manufacturing processes and tools under the joint action, PCD cutting tool price has fallen more than 50%. The trend led to PCD cutting tools in machining of aluminum materials, increasing the tool's applicability is limited by the constraints of different materials to be processed. The basic characteristics of

PCD tool Highly unique mechanical properties of hardness and PCD composite film is a mixture of diamond particles and catalyst sintered at high temperature and pressure, in the synthesis of diamond particles generated in the process of biological and established between the diamond particles connection "bridges" to gain a catalyst island structure, similar to the overall PCD diamond material. PCD materials of the structure and PCBN (polycrystalline cubic boron nitride) material different. In PCBN materials, CBN is no real bond between the material particles; while there is a total of PCD material is biological, diamond particles by lattice "bridges" to connect with each other. antique royal worcester

PCD diamond cutting tool grades based on particle size classification. According to the manufacturer's standard, fine, medium and coarse grain PCD grades corresponding to the diamond size generally were 2 m, 10 m and 25 m. Coarse particles than fine particles PCD PCD grades higher grade strength, wear resistance and better in the rough has a longer working life, but the coarse PCD tool cutting edge is difficult to achieve fine-grained PCD tool surface smoothness. Therefore, the fine particles can be better processed PCD tool surface finish, but wear faster.

PCD cutting tool price changes The past, the price is the impact of user PCD tool widely accepted as a major obstacle, but now the situation has changed greatly. Industry estimates, over the past two or three years, PCD tool prices have fallen by 40% to 60%. PCD cutting tool price appears "diving" One reason is oversupply. In the 20th century, the early 90s, PCD cutting tool momentum began to exceed the traditional carbide tools, in the following decade, the market demand on the PCD tool is increasing. However, with the PCD cutting tool manufacturing technology matures, its Sell Growth began to slow, the current slump in the manufacturing PCD cutting tool on the market to some extent. In addition, new competitors into the PCD tool manufacturing industry is also shaken the market price of the original system. PCD cutting tools is another reason for falling prices continue to lower manufacturing cost cutter, tool manufacturing process (such as the rough diamond rough for the EDM process, the cutting edge of precision processing technology, etc.) continue to improve. In addition, ten years ago, processing and use of PCD diamond tool Grinding wheel Significantly improve the quality and cost is greatly decreased.
