◎ ball screw is turning motion into linear motion, or linear motion into rotary motion of the desired product.
◎ ball screw by a screw, nut and ball composition. Its function is to transform the rotary motion into linear motion, which is a further extension of the ball screw and development, the significance of this development is to slide into the bearing from the rolling action action. Because of small friction, ball screws are widely used in various industrial equipment and precision instruments.
◎ machine tools and precision ball screw is the most commonly used mechanical transmission components, and its main function is to convert rotary motion into linear motion, or torque into axial force over and over again, while both high-precision, reversible and high efficiency characteristics.

 1 compared with the sliding screw drive torque Vice 1 / 3 as ball screw nut screw between the screw shaft and doing a lot of ball rolling motion, so the campaign can get a higher efficiency. And in the past compared to the sliding screw drive torque deputy of 1 / 3 less movement to achieve the same results that the power needed to use the scroll vice screw 1 / 3. Was helpful in saving.
2 to ensure high-precision ball screw made ​​in Japan is the world's highest level of consistent production out of the machinery and equipment, especially in the grinding, assembly, inspection of the process plant environment, temperature and humidity were strictly controlled , due to the quality management system to improve the accuracy can be fully guaranteed.
3  the micro-feed may be used as ball screw ball movement, so a very small starting torque, will not be crawling like sliding movement phenomenon, to ensure accurate micro feed.
4  no backlash, high rigidity ball screws can be added to the pressure, due to the axial clearance can achieve negative pressure, and then get a higher rigidity (by giving the ball within a ball screw to increase pressure in the actual use on mechanical devices, due to the repulsion ball can enhance the rigidity of the Ministry of wire mother).
5   high-speed ball screw feed may be efficient due to movement, heat is small, it can achieve high-speed Feed (movement).
