The claw journal grinding machine is a special machine tool developed to meet the production needs of petroleum machinery manufacturing enterprises. The machine tool adopts FANVCOI-MC series to control the vertical and horizontal interpolation movement of the grinding wheel frame, which can be fully cut into the forming sleeve and grind out the claw shaft. All the outer and end faces of the neck, the set of grinding wheels are modified by the rolling wheel, and an auxiliary grinding head is provided for polishing the claw journal in special cases. The machine tool has high grinding efficiency, stable and reliable performance, easy to use and operate, and overcomes the traditional production process, which adopts half-cutting and secondary grinding, which is easy to cause the workpiece surface to have the marking marks, the dimensional consistency is poor, and the scrap rate is high. China's grinding drilling drill bit jaws are backward in technology, low in production efficiency and high in cost. Since the dental claw journal grinding machine was put on the market, it has been well received by petroleum machinery manufacturing enterprises, achieving a double harvest of economic and social benefits.
The blind flange is used to close ends of piping systems. It is a kind of round plate with no center hold but with all the proper bolt holes. This blind flange is available in various sizes and materials and is used to provide positive closer on the ends of pipes, valves or equipment nozzles. This flange helps in easy access to a line once it has been sealed. The blind flange is sometimes custom made or machined to accept a nominal sized pipe to which reduction is being made.
