The screw rod is composed of a threaded rod, a nut and a ball. Ball screw, also known as ball screw, is composed of screw, nut, ball and other components. Its function is to convert rotary motion into linear motion. Because of its small frictional resistance, ball screws are widely used in various industrial equipment and precision instruments. Ball screw is an ideal product that converts rotary motion into linear motion, or converts linear motion into rotary motion. Ball screw is the most commonly used transmission element on machine tools and precision machinery. Its main function is to convert rotary motion into linear motion, or convert torque into axial repetitive force, and it has both high precision, reversibility and high Features of efficiency. Ultra-high DN value ball screw: high-speed machine tool, high-speed integrated machining center machine, the screw is used in machine tools, lathes, CNC machinery and equipment. (As shown in Figure 1)
Easy to mold and process, it can be molded by compression molding, injection molding, extrusion, calendering, casting, spraying, casting, lamination and blow molding, and secondary processing by mechanical cutting, welding, bonding, and thermoforming. . It can be manufactured into plastic products such as plates, sheets, films, wires, rods, tubes, artificial leather, foams, etc.
   (1) Plastic products are light. The density of most plastics is between 0.9-2.3g/cm3, which is of special significance for machinery and equipment, high-rise building materials, vehicles and aircrafts that require reduced quality of parts.
  (2) Plastics are easy to color. Coloring can make the product have a beautiful and shiny appearance, and make it have an effect similar to wood, marble and non-ferrous metal.
