Highly dynamic NC rotary tables with torque motors
FIBRODYN® direct-drive NC rotary tables have been designed for highly dynamic and high-precision rotation and positioning in machine tools and production equipment. This and additional special design features offer many advantages for the user:
flexible positioning in optional angular steps
zero backlash and high control performance as a result of no gearing
extremely short positioning times, e.g. ts = 0.36 s for 180°
very high or very low constant rotational speed
positioning accuracy up to ±2 angular seconds; with measuring fault compensation below 1 angular second
high repetitive accuracy < 0.2 angular seconds
high precision in terms of radial and axial concentricity in the micrometer range
hydraulic table top clamping as a force-locking connection between the table top and the housing
compact design and no protruding drive elements above the housing contour.
