Saddle welding procedure requires the use of a Saddle Fusion tool. This tool must be capable of holding and supporting the pipe, rounding the pipe for proper alignment between the pipe and fitting, holding the fitting, and applying and indicating the proper force during the heat fusion jointing process. The heating and fusing process must be performed with accuracy and efficiency, especially when fusing to a pressurized main pipe. Automatic saddle welding machines with CNC control system promise operator to follow the welding temperature, welding time and jointing pressure after choosing welding standard, pipe size and material. CNC HDPE reducing tee saddle fusion welding machine, which is produced under a high technology with special design of pipe fusion machines, has the principle of working on the logic of the hydraulic system. For high quality reducer and high accuracy and working efficiency, Wuxi Yuda MRH-A Automatic HDPE Fitting Reduing Tee Saddle Fusion Equipment is your best choose.

Most of the bearing enterprises in China are lagging behind in R&D strength and production technology. Only a small number of R&D companies with strong R&D strength and leading production technologies have the strength to produce high-tech bearings. The lack of capacity causes a serious supply shortage. This series of Problems are the main cause of structural imbalances in the supply and demand of high-end bearings.
At present, only a few companies, such as Axis Research, can mass-produce this grade of products, and there will be huge market substitution in the future. China's CNC machine tool spindle application rate is less than 10%, far lower than the level of developed countries. Now domestic manufacturers that can mass produce CNC machine tool spindles are only a few companies, such as Axis Technologies. Most of them need to be imported. The "planning" will help speed up the import substitution process of high-end bearings. According to the plan, the bearing industry will reach 222 billion yuan in sales in 2015 and CAGR=13.2% in the next five years.
According to the understanding of Xiao Bian, the precision of rolling bearings is generally divided into five grades: P0, P6, P5, P4, and P2. The precision of the bearings used on precision machine tool spindles should be P5 or higher, and for CNC machine tools, machining centers, etc. High-precision machine tool spindle support, you need to use P4 and above super-precision bearings. P4 and above super-precision bearings require high technical performance and reliability, and more than half of domestic demand depends on imports.
In light of these phenomena, Xiaobian's analysis of high-end bearings will be the focus of development. It is expected that bearing companies with advanced domestic technology and high-end products will enjoy the results of import substitution of high-end bearings.
