Abstract

The performance of CNC machine tool is greatly dependent on the precision rotary drives. It is extremely significant to reasonably design the precision rotary drives used to ensure the optimal performance of the machine tool. This chapter first analyzes the errors of the single-coordinate rotary movement. Further, several commonly used transmission mechanisms in the design process of precision rotary feeding system of CNC machine tool are introduced. The characteristics and design methods of common transmission mechanisms, including worm-gear drive, roller drive, and direct drive, in the CNC machine tool rotary feeding mechanism are also summarized. Moreover, the measurement and sensor systems capable of ensuring the movement precision of circular feeding are briefly introduced. Finally, a design case of ultraprecision hydrostatic rotary table is presented to introduce the detailed design process of precision rotary drives. This chapter will contribute to provide technological guidelines to the optimal design of precision rotary drives.
