The indexing table, also known as the dividing plate, CNC rotary table/A-axis, is a core functional component in the broaching of fir-tree slots in precision parts such as aero-engine turbine disks and gas turbine wheels. It is responsible for high-precision circular indexing, powerful clamping, and stable support of the workpiece.
Driven by a Siemens servo motor that matches the Siemens control system of the equipment, the table operates through a reducer that drives a synchronous belt pulley, which in turn drives a worm gear pair, rotating the worktable coaxially with the worm gear. It can rotate in both forward and reverse directions with stepless indexing. A high-precision Heidenhain angle encoder provides real-time feedback of the current rotary table angle to the system, thereby achieving a closed-loop position monitoring system that corrects the error between theoretical and actual indexing, fully ensuring the rotational positioning accuracy of the indexing table.
The rotary table can achieve indexing at any angle within 360°. It is equipped with a pressure intensifier and hydraulic valves, and employs an annular piston spring clamping method. During indexing, the clamping is hydraulically released, fully ensuring stable and reliable operation during the working process.
The indexing table can be customized according to user requirements, including parameters such as clamping torque and table surface height, to meet the actual needs of users.
