Precision rotary tables with worm gear
This multisided applicable precision rotary table is available in installation size of 300 mm of rotary plate diameter. The rotation plate is stored by a tempered roller-bearing. This enabled high moment rigidity within the radial and axial range as well as free positioning at less friction moments. The drive takes place alternatively via stepper- or AC servomotors by a hardened and polished precision worm with a worm wheel of bronze. The rotary table is horizontal and vertically applicable by standard drilling plan and bolting face.
Field of Applications | Assembly technilogies, measuring and testing equipments, laser writing, welding, cutting, as well as special mechanical engineering. The standard light aperture can be used for optical systems or for execution by cable. |
Drive | Worm drive i=72:1, with simple measure-oriented adjustment. Flange and coupling are available for all common stepper- and servomotors (motors are not included, please ask for suitable motors). |
