As the largest market in the tool industry, the automobile industry has developed rapidly in recent years. This situation is like a double-edged sword. It provides a huge development space for tool manufacturers, but also brings great challenges to traditional processing. Processes and Tools cannot solve the problem of cutting on high-hardness parts until the emergence of PCD and PCBN tools. Shanghai Shunjie Electromechanical Technology Co., Ltd. (referred to as Shanghai Shunjie) is a diversified company integrating tool manufacturing, machine tool development and machine tool manufacturing. In just six years, the company has developed a number of new products, including the SRT brand PCD gun drill, which is the company's top flagship product, pure German craftsmanship, superb technology and high quality products have achieved high in the industry. Recognition. PCD tool PCD tool is a kind of polycrystalline diamond synthesized by high pressure synthesis technology, which solves the problem that natural diamond is rare and expensive. Its super-hard alloy hardness and precision can be applied to aerospace, aerospace, automotive, electronics and other fields. Among PCD tools, PCD gun drills represent our advanced technology. The gun is a well-known name that accelerates the pace of the weapons manufacturing industry and becomes an irreplaceable tool for arsenal and special hole processing. Now it has appeared frequently in the processing industry of mold manufacturing, aerospace, aviation, automotive oil pump nozzles and so on. It has also become an irreplaceable punching tool in the processing of the automotive industry. Parts that require punching, such as gearboxes, engines, gear shafts, connecting rods, etc., require gun drills to solve. When drilling, the PCD gun drill has a self-guided guide bar to support it. The arrangement of the bars has an important influence on the surface quality and dimensional accuracy of the machined holes. The cutting force during machining forces the bar to press against the wall of the hole to produce roller light, which can effectively improve the size and precision of the part. Its advantages include: in the field of small diameter deep hole processing, it is almost the only effective tool. The larger the aspect ratio, the more remarkable the superiority. The maximum tool length can reach 5000mm; the cutting performance is high. Because of the high speed, the feed rate is large, and the continuous feed does not need to retract the chip in the middle. The stable aperture size can reach the IT8 under the general conditions. ~9 grade, up to IT7 under certain conditions; the surface roughness of the machined hole is good, the processed steel can reach Ra0.8~1.6, the processed non-ferrous metal and cast iron can reach 0.8 or less; the high shape tolerance, the roundness of the hole 0.005mm, axis straightness 0.2mm/1000mm; high adaptability range, the hardness of the material to be processed reaches HRC45 can still be processed; the tool has high durability, the processing of ordinary steel 5~15m sharpening once, the cast iron 50m sharpening once, the aluminum is about 380m Sharpen once. The cutter head can be sharpened 10~20 times, and its total life is very long. After the hole is drilled, the hole has no flash and burr; it is suitable for machining centers and lathes equipped with high-pressure cooling system; the minimum amount can be used under certain conditions. Lubrication system (MQL). PCBN tool PCBN tool is a cubic boron nitride synthesized at a high temperature and high pressure. Its hardness is second only to diamond and much higher than other materials, so it is collectively referred to as superhard material. The machining method is mainly to machine the cylindrical workpiece by means of the tool fixed workpiece rotation, and the other is to cut the workpiece back and forth by the workpiece fixed tool Z axis. Although PCBN is already a relatively mature tool material, coating, cutting edge preparation and chipbreaker are very important for the processing of PCBN tools, but there is no way for hole machining. The processing of deep-hole parts has become a new problem that hinders the development speed. More and more processing of hole-type parts has plagued the processors. Nowadays, the civilization of deep-hole drilling machine tools and gun drills has completely solved this problem.
