High Surface Copper Screw
Screw in the machine there is a component is elongated by long metal bar manufacturing. The above is finish high surface, some even with a thread. In general machine tools it has thread, that screw.

1, according to GB/T17587.3-1998 and some application examples, ball screw (has basic replace trapezoidal screw, already commonly known as screw) is used for the rotary movement into linear motion; Or will linear motion into rotary motion execution element, and has high transmission efficiency, accurate positioning and characteristics;
2, when screw as active body, copper wire rod mother can follow screw rotation Angle, in accordance with the corresponding specification lead into linear motion, passive workpiece can through the nut seat and nut connection, so as to realize the corresponding linear motion.
3, ball screw nut room because there was no clearance, linear motion accuracy is higher, especially in frequent reversing without backlash compensation. Ball screw wire mother friction between the small, turns very easily.
4, ball screw and motor connection must be among the coupling in order to achieve flexible connection. Synchronous belt is can directly use synchronous wheel and motor output shaft connection.
5, ball screw pair on the basis of the national standards GB/T17587.3-1998, divided into positioning the ball screw pair (P) and driving ball screw pair (T) two kinds big. Accuracy grade is divided into seven class, the 1.2.3.4.5.7.10 level, the highest accuracy level 1. In turn reduce.
6, ball screw rotation week nut moving distance for a pitch distance, if it is screw each turn a week nut mobile 4 (or 5) spiral line distance, then said the screw is four line (or five line) screw, commonly known as the four head (or five head) screw. General small lead ball screw is used single wire, medium, or large lead by using two line or more line.
