Example of use
All linear axes of the linear units LES 5 (x- and z-axis) and LES 6 (y-axis) that are use here run on grinded steel shafts with linear ball bearings. Clearance-free ball screw drives with hardened and polished 5/8''-16 spindles with a pitch of, optionally, 2.5/4/5 or 10 mm are used as drives. The linear axes are driven by powerful and robust DC or AC servo motors in easy-to-maintain drive modules.
