Item 517.019 is a revolving bar/unit designed for “Cucchi” bar feeders with right-hand thread. The component is manufactured to ensure a stable and precise connection within the feeding system, helping maintain continuous operation and reducing the risk of vibrations, jamming or abnormal wear caused by incorrect threads or dimensions.

Revolving units are made from certified highly alloyed steel, then hardened and ground to guarantee reliability and long service life. The production process is carried out entirely in Italy using high-precision machine tools and a strict quality control, ensuring correct performance even in demanding production cycles.

This is the ideal choice for maintenance and to restore the efficiency of the bar feeder when wear marks, play or loss of smooth motion are detected. Before ordering, it is always recommended to check the dimensions and threads of the installed part.

The item is suitable for use on CNC lathes with fixed headstock and sliding headstock that use Cucchi bar feeders with right-hand thread, for operations such as internal and external turning, drilling and milling. It is suitable for a wide range of materials: ferrous materials, low-alloy and high-alloy steels, cast irons, nickel alloys, titanium, bronzes and brasses, and composite materials.

The bar pusher collet is mounted on these revolving units: since the component is assembled with bearings, it takes the rotation of the main spindle once the bar is clamped by the bar clamping collet, ensuring stable operation consistent with the machine dynamics.
