Rolled Steel Accuracy Heavy Duty Ball Screw for CNC Machine Robot Router

Ball screw assembly is a high-precise mechanical drive part made up of screw, nut, ball bearing, sealing washer and other components, for there are ball bearingrolling between the screw and nut, the ball screw can receive high movement efficiency, compared with slide guide screw, the drive torque is under 1/3. So that it is easy to translate turning movement to straight-line movement, also, it is easy to translate straight-line movement to turning movement. It is a kind of further expansion and development of traditional slide guide screw. The profound significance of this development is the same as the transformation brought by rolling bearing to slide bearing. Due to its fine friction character, ball screw assembly is widely used in various industrial equipments, precise apparatus and precise numerically-controlled machine tool. Especially in recent years, work as executive unit of straight-line drive of numerically-controlled machine tool, it is broadly used in machine tool industry, and greatly promotes the numerically-controlledDevelopment of machine tool industry. All of these lie on several fine Characters as follows: High drive efficiency, high orientation precision, reversibility of drive, long service life, good synchronous performance

A ball screw is a mechanical device for translating rotational motion to linear motion. A threaded shaft provides a spiral raceway for ball bearings which act as a precision screw. As well as being able to apply or withstand high thrust loads they can do so with minimum internal friction. They are made to close tolerances and are therefore suitable for use in situations in which high precision is necessary. The ball assembly acts as the nut while the threaded shaft is the screw.
Ball screws are used in aircraft and missiles to move control surfaces, especially for electric fly by wire. They are also used in machine tools, robots and precision assembly equipment. High precision ball screws are used in steppers for semiconductor manufacturing. Small ballscrews are often used to move the read heads of floppy discs and compact disc players.
