Highest quality made in Germany with high-precision worm-gear and a stopping moment of over 20Nm 3D 360° is possible with almost all materials e.g. plastics, timber, Aluminium or even brass, engraving of all kinds. Mounting holes: Diameter 7 mm with spacing 150 mm (4 vertical, 4 horizontal) therefore the rotation table can be clamped horizontally as well as vertically, providing great flexibility in setup. Overall height vertical: 145 mm Overall height horizontal: 70 mm Top height: 60 mm Faceplate diameter: 109 mm Maximum feed diameter: 120mm Running time: 0.025 - 0.04mm Parallelism Mounting surface horizontal / contact surface Faceplate: 0,02 - 0,03mm Centering flange diameter: 55 h7 mm Circular running accuracy: 0.015 - 0.025 mm Reversing play maximum 0.04 ° Internal cones: MK 1 Internal bore / through hole: D = 10.3 mm Bearings: 4-position sealed ball bearing / preloaded, play-free Output torque: 20 Nm! Weight: 3.9 Kg High-precision, ground worm gear with gear ratio: 100: 1 / preloaded with disc springs Rotations on the chuck flange: from 0.1U / min to approx. 3.2 rpm. Step resolution at the output: 160,000 steps per revolution with 1/8 step operation Setting accuracy +/- 1 step - corresponds to +/- 0.135 angular minutes
