Abstract

PURPOSE:To absorb crosswise vibration of a spindle feed screw of a discharge processing device etc. and enhance thereby the straightness of the spindle's motion by mounting the female screw in such a way that the female screw, which is to provide feed motion in linkage with the screw for feed of the spindle, is restricted in the feed direction and capable of flat movement freely in the direction normal to the feed direction. CONSTITUTION:A pad 9 of electromagnetic brake 7 is released, and rotation of a servomotor 1 is transmitted to a ball screw 4 connected to the shaft 2, where female screw 14 is capable of crosswise movement within the gaps g1, g2 with respect to the spindle 19 for the purpose of absorbing transverse vibration of the ball screw generated by swing of rotating bearing 10, warp of ball screw 4, misalignment of the bearing part 4a and screw part 4b, etc. This transverse movement is provided by a floating mechanism composed of a plate 16 and steel ball 17. The axial movement of the female screw 14 is restricted by a set screw 20 while the rotary movement of the same by a guide pin 24 and a guide 25.
