Aerospace products are constantly being upgraded, especially with the widespread use of various composite materials that are difficult to process, and their processing technology is gradually improving. At present, PCDPCBN materials are increasingly used in the aerospace industry. PCD tools have been widely recognized for their excellent cutting durability and high toughness. However, because of their high hardness, the difficulty of tool sharpening has been plaguing many users. PCD tools not only start to purchase high cost, but also the cost of later grinding. Very high, and the general grinding cycle is also relatively long. Therefore, the manufacture and repair of PCD tools has been a common concern for many tool manufacturers.
Japan Rhombus RYOCO specializes in PCD tool PCBN tool development and development of various types of CNC equipment for different tool materials and a variety of processing methods, its technology has been recognized by the market for many years. As we all know, because of the PCD tool price factor, the PCD blade is generally welded to the cemented carbide substrate. Therefore, in terms of processing efficiency, the grinding of the PCD material regardless of electrolysis is very slow. Therefore, the Japanese Rhombus RYOCO equipment adopts its unique double-end grinding shaft structure. The main shaft 1 is equipped with a diamond grinding wheel, which is used to grind the hard alloy part of the tool to complete the 2nd 3rd back angle of the tool, and then the electrolysis on the main shaft 2 The copper wheel is processed by the discharge method to the first back angle of the tool and the contour. The quality of electrolytic machining efficiency is also controlled by the program. After four steps, the surface quality can reach Ra0.1μm. However, the high-hardness and high wear resistance of the actual processing and grinding PCD material brings great difficulties to the processing. For many years, most of the market's use of EDM or chemical processing and laser processing technology is often more suitable for roughing applications. To achieve the highest level of PCD surface quality, the most ideal processing method is still inseparable from grinding.
Although the grinding electrolysis function is also integrated, the original process technology of grinding ensures the reliability of processing reliability. The constant grinding force control makes the grinding wheel always fit the surface of the machined PCD, thus avoiding the excessive wear of the grinding wheel due to the increase of the grinding force, resulting in the gap between the grinding joint surface and the surface quality of the tool due to the reduction of the grinding force. reduce. Similarly, the grinding ratio is very small when machining PCD materials, so the machining time is relatively longer, so the constant grinding pressure control guarantees the entire surface quality of the cutting edge accuracy. With up to 6 grinding wheel spindles, you can install up to 12 grinding wheels at a time, a small grinding wheel library. At the same time, the high-speed spindle with internal cooling can achieve a maximum speed of 30000r/min.
Japan Rhombus RYOCOPCD tool processing, regardless of high-speed grinding and creep grinding, its spindles are given high precision and reliable guarantee. Considering the grinding process, the surface of the grinding wheel is often passivated because it is blocked. Therefore, the LGMAZK machine is equipped with a grinding wheel trimming and sharpening device. Combined with the program control, the grinding wheel is sharp and timely, so that the grinding wheel maintains a sharp state, thus shortening the whole Processing beats ultimately improve processing efficiency. In addition to the different processing methods to suit different applications, LGMAZAKMAZAK has accumulated a lot of commonality for PCD tool grinding. Because they know the PCD tooling process, the machine design and accuracy are also guaranteed for the final tool quality.
Because PCD materials are difficult to process and wear, the rigidity of the machine is particularly important in the case of strong grinding loads. The concrete structure bed and the patented gantry frame structure make the rigidity of the machine tool load to the extreme. Direct drive of each axis greatly increases the entire grinding process and ultimately improves grinding efficiency. The electronic shaft workpiece is used to clamp the shaft, and its structure avoids the wear of mechanical parts and reduces the gap generation, providing extremely high rotation precision. Grinding is performed in a single clamping and one-time forming process, thus ensuring that the tool machining circumference is less than 5 μm. LGMAZAK machine tool provides line measurement function, which better guarantees the precision control of tool processing. When processing PCD material, it is often found that the cutting edge is microscopically chipped due to improper control of grinding force, so the line measurement function can be used in time. The defects are found and the quality of the processing is guaranteed under the premise of clamping. PCD tools can only be used to ensure the quality of tool processing by using suitable equipment and a reasonable sharpening method. Only by comprehensively considering the factors involved in the tool manufacturing and grinding process can high-quality tools be obtained, and the cost of tool use can be reduced, ultimately improving the overall Tool product quality. On this development path, LGMAZAKMAZAK will make unremitting efforts and combine the actual needs of the market to provide more and better solutions for tool grinding.
