The bronze bushing code 3511132 is a mechanical component designed for the central block actuation system of Gildemeister GM35 and GM35AC multi-spindle automatic lathes. The bushing is installed between the central pin and the actuation lever, acting as a sliding and coupling element within the mechanical linkage system.

The central block represents a highly versatile operating station of the machine. The hexagonal block allows the installation of different machining devices used during turning operations and complementary processes. Typical configurations 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 for screwdriver slot cutting.

The bronze bushing ensures a stable coupling between the lever and the central pin, reducing friction between metal surfaces and enabling smooth and controlled movement of the actuation system. Thanks to the tribological properties of bronze, the component distributes mechanical loads efficiently and protects the main elements of the kinematic mechanism.

During machine operation the central block actuation system is subjected to cyclic stresses generated by continuous motion of the mechanism. Over time this can lead to wear of the bushing and progressive ovalization of the internal bore, increasing mechanical clearance between the lever and the pin.

When this occurs the precision of the central block movement may decrease, potentially affecting machining stability. For this reason the bushing is designed as a controlled wear component, intended to be replaced during preventive maintenance operations in order to protect the central pin and lever assembly.

Maintaining this component in proper condition significantly contributes to the stability and accuracy of the central block system in Gildemeister GM35 and GM35AC multi-spindle automatic lathes.
