"WebbIn a ball screw axis, as well, a rotatory servo motor is coupled to a linear module. In this case, the motor drives a ball screw whereby the carriage connected to the ball screw nut moves back and forth. Ball screw axes are a good choice for applications in which high forces at low to medium speeds are required. Further information Linear Motors " - Screw axes

Thread the lead screw into the Z-gantry anti-backlash block between the two steel plates. Fasten two M5-25mm bolts on both sides of the Z-axis motor mount to secure the two assemblies together.

WebbGlide planes and screw axes. Two of the symmetry operations involved in the space groups are not contained in the corresponding point group or Bravais lattice. These are the compound symmetry operations called the glide plane and the screw axis. A glide plane is a reflection in a plane, followed by a translation parallel with that plane.
