Rotary table structure for precision finishing machine

The invention relates to a rotary table structure for a precision finishing machine, belonging to the field of advanced manufacturing. The rotary table structure for the precision finishing machine is an improvement on a rotary table structure of the traditional finishing machine. In the invention, on the structural design of a rotary table an idea of modularization design is applied, and an integral rotary table part is arranged on a slide carriage through a rotary table base; on a driving control manner of the rotary table, a moment motor is adopted for direct driving, a transmission chain is shortened, and the high-accuracy angular displacement feedback is realized by adopting a high-accuracy encoder; and on a guide rail form of the rotary table, a liquid hydrostatic guide rail form is adopted by matching with upper and lower hydrostatic discs and a large-caliber center shaft of the rotary table. The rotary table for the precision finishing machine has the advantages of convenience, easiness and effectiven
