Use of product-A rotary table is a precision tool used predominantly in metalworking, particularly in machining operations like milling and drilling. Its primary function lies in enabling machining at precise angular intervals around a fixed point, commonly referred to as indexing. This capability facilitates the creation of intricate geometries, circular features, and multi-sided machining without the need for manual repositioning of the workpiece. By mounting the workpiece on the rotary table and rotating it, machinists can execute complex operations such as gear cutting, spiral grooving, and helical cuts with high precision.
