The six major points in the development of global CNC cutting machine tool application technology 1. The application of composite machining technology is more extensive. New compound processing machine tools such as turning and milling machine tools, car grinding compound machine tools, gear processing compound machine tools, turning and milling composite and 5-axis linkage machine tools Such products continue to emerge; heavy-duty machine tools add multi-functional accessories and turntables, etc., the trend of composite processing is obvious; metal cutting and special processing compounding has made new progress, and laser, electric processing and cutting processing composite technology has already mature products. The popularization and application of composite processing technology will have an important impact on multi-variety and small-batch production processes. 2. The application speed of direct drive technology is accelerated. Due to the advancement of power electronics and numerical control technology, as well as the maturity of components such as linear motors, torque motors, electric spindles, and grating inspections, the application speed of direct drive technology in CNC machine tools is accelerating. The new product has been driven by a linear motor. The application of direct drive technology will greatly promote the structural change and performance improvement of CNC machine tools. 3, micro-manufacturing technology emerges Micro-manufacturing (Inter-Micro) refers to a high-efficiency, green, high-precision micro-manufacturing technology for processing various micro-parts in 3D shape. At present, with the support of the European Union, research teams composed of universities, research institutes and enterprises from Germany, Italy and other countries have achieved relevant results, such as: ultra-precision 5-axis linkage micro-diamond and cubic boron nitride tool processing technology equipment. . Micro-manufacturing technology has great application potential and should attract the attention of the industry. 4, low-temperature processing technology into practical Studies have shown that the application of low-temperature processing technology chip removal rate is 2-4 times the original processing method, tool life can be extended by 2 times. Especially in the field of hard metal cutting such as titanium alloy, nickel-based alloy, ductile iron (CG1), the cutting effect is remarkable. Foreign companies have introduced low-temperature processing technology equipment and gained application experience in aerospace manufacturing. 5. Green manufacturing technology is emerging Green manufacturing technology is an integrated technology. Saving energy, saving resources and increasing productivity are the core requirements of green manufacturing technology. The application of green manufacturing technology is an urgent issue in the development of CNC machine tools in China. In fact, the application of green manufacturing technology is both an objective requirement for sustainable development and a need for market competition. 6. “Solution†is an important form of industrial development. Providing “solutions†for users, reflecting the integration of technology and management, is an inevitable requirement of technological advancement in the times. A comprehensive solution is an advanced form of today's manufacturing services. In the future, the machine tool processing enterprise will not be able to meet all the requirements of the customer only by providing the host computer. Only by providing a one-stop "solution", becoming the "technologist" of the user and providing "long-term service and contract" can it be fierce. Win the order in the market competition.
Lap Joint Flanges
Lap Joint Flanges (LJ Flanges) are used on piping fitted with lapped pipe or with lap joint stub ends the combined initial cost of the two items being approximately one-third higher than that of comparable Welding Neck Flanges.
Lap joint flange is having two components, a stub end, and a loose backing flange. Stub end is butt welded to the pipe and Backing flange freely move over the pipe. The backing flange can be of different material than stub material and normally of the carbon steel to save the cost. Lap flange is used where frequent dismantling is required, and space is constrained.
Furthermore, a standard lap joint flange will typically have a longer hub length in comparison to a slip on flange, but this is often considered unnecessary for many applications.
The lap joint flange is practically identical to a slip-on flange except it has a radius at the intersection of the bore and flange face.
