Geometry accuracies High geometric accuracies as standard, combined with a high level of rigidity and stability ( ) values = increased accuracy. Item no. GEO.5xx-GEN EA + M Overview The tolerances given below apply under the following conditions: 1. The rotary table is mounted as specified in the commissioning instructions 2. The measurement is carried out on a calibrated granite plate (all machine errors are excluded) 3. The rotary table is not subjected to any outside thermal influences (sun, fans, heaters...). 4. P rior to the measurement, the rotary table and the measuring and test equipment have been in the same environment for at least 24 h 5. All measured values are determined for an unloaded rotary table Perpendicularity Spindle surface to support surface Parallelism Spindle axis with support surface Center height 0.01/100 mm (0.005/100 mm) 0.01/100 mm (0.005/100 mm) 0...0.04 mm Parallelism with support surface Parallelism with tilting axis For longFLEX, see p. 41 0.007/100 mm (0.0035/100 mm) 0.01/300 mm (0.005 /300 mm) MOT / KAB WMS / CNC T2 / T3 T1 TF Geometry of EA rotary tables Workpiece clamping RFX/LFX Geometry of EA rotary tables with rotoFIX Geometry of M rotary tables Parallelism Spindle axis with support surface Center height 0.01/100 mm (0.005/100 mm) 0.01/100 mm (0.005/100 mm) 0...0.04 mm Axis parallelism Spindle 2, 3 and 4 to spindle 1 Center distance X1, X2 and X3 Depth difference of the spindles 0.01/100 mm (0.005/100 mm) 0.02 mm (0.01 mm) General accessories Perpendicularity Spindle surface to support surface Technology / engineering A on request 70
