High positioning accuracy HIWIN MGW15CH linear guide

Description of for ball screw :

    1.Ball screw is to convert rotary motion to linear motion, or convert linear motion into rotary movement of the ideal product. When ball screw consists of screw, nut and ball.

Its function is to convert rotary motion to linear motion, this is the further extension and development of the ball screw, the significance of the development is the slide bearings from scrolling action into action.

    2.Because of the very small friction resistance, ball screw is widely used in all kinds of industrial equipment and precision instruments. When ball screw is the most commonly used on machine tools and precision machinery transmission components, its main function is to convert rotary motion to linear motion, or will be converted to repeated axial force, torque and combines the characteristics of high accuracy, reversibility and high efficiency. 

Have the characteristics of ball screw:

1, compared with sliding screw pair drive torque for a third

 Because the ball screw pair between the screw shaft and the screw nut has a lot of rolling ball doing sports, so can get higher movement efficiency. 

 2 and the guarantee of high precision

 Ball screw pair is generally is coherent with the world's highest level of mechanical equipment manufacturing, especially in the grind cutting, assembly, inspection factory environment aspects of each process and strict control of temperature, humidity, due to the perfect quality management system to ensure adequate precision.

 3, micro feed

 Ball screw pair is due to the use of ball movement, so start torque, there will be no sliding movement that crawl phenomenon, can realize the accurate assurance of micro feed.

 4 no side gap and high rigidity

 Ball screw pair can be added to the pressure, due to the pressure can make the axial clearance to negative, then get high rigidity (ball to add to pressure on the ball screw, in the actual used for mechanical device and so on, due to the repulsive force of ball can make silk mother rigidity increase).

 5, high speed feed

 Ball screw due to the movement of high efficiency, low fever, so it can realize high speed feed (movement)
