This part of GB/T 33524 specifies the mounting hole series dimensions of the modular conical interface with steel ball tensioning system for automatic tool change and manual tool change machine tools (such as lathes, drilling machines, milling machines and turning-milling centers). Torque transmission is achieved through friction at the end of the tool holder, clamping elements and keys.
