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.

The rotary table features innovative dual lead worm drive, and high torque, high accuracy, and superior performance. The indexing accuracy of rotary table is equal to the sum of the maximum difference of the positive value and that of the negative value, as and absolute value. The allowable torque for the worm wheel is subject to the standard stipulated by the Japan Gear Manufactures Association. The chart about indexing accuracy has three dimensions: table turning angle and indexing measurement data, table turning angle, indexing measurement date. This allowable wheel torque of rotary table is equal to the allowable torque for the worm wheel when the table rotation is 1 rpm. About the rotary table, it has variety applications, for working example, 4th axis and 5th axis rotary tables which supply customers with total solution.
