Manual positioning table drived by lead screw Guided by 2 rods on bronze bearings or ball bushings Options : Handwheel or grip knob Positioning indicator Position clamping Assembly in manual XY positioning table Precision manual tables The guidance is ensured by 2 rods on 4 calibrated bronze bearings (reduced play) or 4 ball bushings for guidance without play. The guide length of long body tables (309L/M) allows to accept large loads and torques. The axial positioning accuracy of these tables is <0.15 mm (in practice 0.02 to 0.10 mm). But the blocking in position is done on the carriage, by pressure on a guide rod, so as to remove the axial play of the nut of the trapezoidal screw after blocking. Manual crossed tables XY or YZ For the creation of XY crossed table, the tables are mounted one on the other directly by the body (long body version only) with the option 308922 * making smooth holes in the body of a table. To combine 2 tables in YZ, it is preferable to use a lifting table for the Z axis, mounted by its end on the body of the horizontal table. Handwheel, indicator and maxi stroke of manual tables The shaft outlet is threaded to directly screw the handwheel or the grip knob with or without position indicator. Consider the reverse display of the indicators when the table is mounted vertically. The maxi achievable stroke is 750 mm, and any intermediate stroke can be produced. Other manual tables This range is completed by the lifting tables which are fixed by 1 end, and the tables with reversed step (the 2 bodies approach or move away symmetrically) and for simple applications, we recommend economical tables.
