1, the ball screw is composed of screw, nut and ball. Ball screw is an ideal product to convert rotary motion into linear motion or linear motion into rotary motion. Ultra-high DN ball screw: high-speed machine tools, high-speed integrated machining center machines, and screw rods are used in machine tools, lathes, and numerical control mechanical equipment. It is the most commonly used transmission element in machine tools and precision machinery. Its main function is to convert rotary motion into linear motion or torque into axial repetitive force, which has the characteristics of high precision, reversibility and high efficiency. Kgr 2, the screw is composed of a single screw and thread, without balls. One of the most critical components in the injection system. It also has the functions of plasticizing materials and injecting materials into the mold cavity. When plasticizing, the heating of the machine and the rotation of the rod make the plastic melt in the process of forward transportation, and turn the solid plastic into viscous melt; Move forward during injection, and inject the melt at the front end of the barrel into the workpiece in the mold cavity. Double alloy screw, extruder screw. Application scope of lsf3 products Guangzhou ball screw has been widely used in positioning and high-precision control machinery and equipment of various industrial machinery, such as precision tool machine tools, high-precision electronic mechanical equipment, conveying machinery and other equipment. There are also turret milling machines, gantry milling machines, lathes, spark machines, vertical lathes, grinders, woodworking machinery, printing machinery, textile machinery, packaging machinery and industrial machinery, and medical X-ray perspective photography devices. , is widely used.
