ねじ。 A screw shaft with a helical ball groove that is rolled and then finish ground on the outer peripheral surface, and a spiral ball groove on the inner peripheral surface that can be fitted externally to the screw shaft and corresponds to the ball groove of the screw shaft. The screw shaft is equipped with a nut and a large number of balls that are rotatably filled into a spiral passage formed by both ball grooves formed by externally fitting the nut onto the screw shaft. A ball screw that is provided with a grinding fluid filling groove that is filled with grinding fluid that is formed by rolling the groove and does not require final grinding.
