Kinematic analysis and simulation of a new type of differential micro-feed mechanism with friction.

Science progress Sep 18, 2019
This article presents a new micro-feed mechanism, whose main transmission component is the nut-rotary ball screw pair. The screw and nut are driven by two motors, and they rotate in the same direction, with their movements enabling micro-feeding. The...
