[0002] The rotary table is a machine tool accessory with a rotatable tabletop for clamping workpieces and realizing rotation and indexing positioning. It is referred to as a turntable or the fourth axis. Turntables can be divided into two categories: general turntables and precision turntables according to their functions. They are important accessories for boring machines, drilling machines, milling machines, and slotting machines. They are used to process holes, slots, and inclined surfaces with indexing requirements. When the worktable is rotated during processing, arc surfaces and arc slots can be processed. General turntables are divided into horizontal turntables, vertical and horizontal turntables, and universal turntables according to their structures. Precision turntables are divided into optical turntables: a glass or metal precision dial is installed on the spindle, and the scale is subdivided and magnified by the optical system, and the angle value is read through the eyepiece or light screen.
