FMT-GX-350/650 type gate valve grinding machine
- FMT-GX-350/650 type gate valve grinding machine is based on the advanced models of domestic and international nuclear power system valve grinding machine. It has long-term accumulated rich professional experience, combined with domestic valve running wear status and repair requirements, high efficiency and precision of patent design and manufacturing. Versatile and easy to operate professional on-site maintenance tools.Main feature:1.The advanced special machine setting can repair the sealing surface of the valve body and valve disc.2.The main assembly adopts the quick-fit short-circuit square thread structure to be screwed and disassembled conveniently and quickly.3.The clamping and pressing device facilitates the three-dimensional adjustment of the grinding head box in the up, down, left and right, front and back; the output of the grinding head box group is floated by the ball head, which facilitates the effective matching of the grinding disc and the surface to be ground to ensure the grinding precision.4.Advanced eccentric vibration and external cycloidal motion, to create a trajectory very similar to manual grinding, to ensure that the surface of the study reaches a high level of flatness.5.High-strength mechanism and high-precision ultra-thin rigid grinding discs can maintain extremely high precision under the condition of large lateral pressure.6.This model is equipped with a valve-grinding bracket, which can be electrically adjusted to the tooling angle （0-15 degrees） and equipped with an electric spring-loading device （by which the pressure set on the sealing surface can be accurately repeated） Make the research valve valve easy, fast and high quality.7.Rough grinding uses high-quality resin diamond grinding tools to remove the defects of the grinding surface; it is finished with the selected sanding paper （no adhesive sandpaper is used）. Easy to use, ergonomics and quality are significantly improved. The precision of the research is up to 80% in radial compliance and 0.2μm in surface roughness, which is especially suitable for steam and water.
