The control lever code 3711109 is a mechanical component designed for the central block actuation system of Gildemeister / DMG Mori GM35 and GM35AC multi-spindle automatic lathes. The lever is part of the mechanical linkage that transmits motion from the connecting rod and articulation pins to the machine’s central block assembly.

The central block represents one of the most versatile working stations of the machine. The hexagonal block allows the installation of several tooling systems used during turning operations and complementary machining processes. Typical applications include workpiece support roller holders for stabilizing the part during turning, front tool holders for rough machining, rotating front milling units for front milling operations and tools used for screwdriver slot cutting.

The control lever converts the motion generated by the actuation system into a controlled movement of the central block. The geometric precision of the component and the quality of its mating surfaces ensure stable kinematic behavior, reduced transmission play and reliable operation of the mechanism.

During machine operation the lever is subjected to cyclic mechanical loads generated by the continuous movement of the central block control system. For this reason the component must provide high mechanical strength and dimensional stability over time in order to maintain precise and reliable movement of the central block assembly.

Maintaining this component in proper condition contributes significantly to machining stability and operational precision in Gildemeister / DMG Mori GM35 and GM35AC multi-spindle automatic lathes.
