Rotary Tables manufactured by Tanshing employ high precision dual worm gear and worm wheel assemblies, feature easy backlash adjustment, and maintain high precision even after long term use. High quality taper roller bearings ensure center of rotation remains very stable. A fully surrounded hydraulic table locking clamp locks the entire circumference of the indexing table in place to reduce stress and any table instability. The result is a high rigidity rotary table able to withstand the forces applied during heavy cutting. The solid, fully sealed structure of the rotary table is completely protected from chips, cutting fluid, and dirt entering the structure.
