The control pin code 3511122 is a mechanical component designed for the central support movement system of Gildemeister GM35 and GM35AC multi-spindle automatic lathes. The component is installed in the connecting rod code 3711115 and transmits motion to the lever that actuates the machine’s central support assembly.

The central support is one of the most versatile operating stations of multi-spindle automatic lathes. The hexagonal block allows the installation of various tooling systems used during machining operations. Typical applications include workpiece support roller holders for stabilizing the part during turning operations, front tool holders for rough machining, rotating front milling units for front milling operations and tools used for screwdriver slot cutting processes.

The control pin functions as the connection element between the actuation linkage and the central support assembly, ensuring precise motion transmission and stable kinematic performance. The dimensional accuracy of the component and the quality of its mating surfaces help minimize transmission play and maintain reliable operation of the control mechanism.

During machine operation the pin is subjected to cyclic loads generated by the movement of the central support control system. Therefore the component must ensure high mechanical strength, wear resistance and dimensional stability in order to preserve machining precision and long-term reliability of the central support actuation system.

Maintaining this component in proper condition contributes to the stability and accuracy of Gildemeister GM35 and GM35AC multi-spindle automatic lathes used in high-productivity industrial manufacturing.
