The Nuova PTM CSF live centre with extended point, also known as a tracing point, is a professional lathe accessory designed to support the workpiece during turning, finishing and between-centre machining operations where stability, precision and high load capacity are required. Its main function is to keep the workpiece correctly aligned during rotation, counteracting the forces generated by the cutting tool and helping to reduce vibration, deflection and possible geometric errors on the machined component.

The CSF series stands out thanks to its large-section body, a construction feature that allows the installation of large-size bearings and increases the overall strength of the live centre. This configuration is particularly important in demanding machining operations, because it allows the live centre to maintain stable support even under high axial thrust and higher working loads compared with a conventional live centre using the same Morse taper.

The extended point provides a specific operational advantage: it improves accessibility in the contact area with the workpiece and allows machining of components with more complex geometries or where additional clearance around the point is required. This solution is useful when the operator needs to bring the cutting tool closer to the machining area while maintaining workpiece support, or when the shape of the component requires a slimmer point than a standard version.

Another key benefit of the CSF series is the possibility of moving the tool carriage closer to the workpiece. This reduces the need to work with an overhung tool and increases the rigidity of the entire machine-tool-workpiece system. A less protruding tool works with lower deflection, reduced vibration tendency and greater cutting stability. In practical terms, this helps improve surface finish, dimensional accuracy and the control of form errors such as unwanted taper, ovality, surface chatter or geometric variations caused by process instability.

The construction with a central shaft as long as the body is another important technical feature. This solution increases the internal structural continuity of the live centre and distributes loads more effectively during operation. The live centre can therefore withstand high working loads and high axial thrust, while maintaining stable rotation and effective workpiece support. This design makes the CSF series especially suitable for applications where the live centre must resist significant forces without compromising rigidity, accuracy and service life.

From an application point of view, the CSF live centre with extended point is suitable for machining shafts, pins, bushings, cylindrical parts, turned components, precision mechanical elements and workpieces requiring reliable support between centres. It can be used in turning departments, machine shops, production areas, industrial maintenance, automotive manufacturing, machine construction and all machining processes where workpiece position control is essential for consistent quality.

For correct use, it is important to check the compatibility of the Morse taper with the machine, carefully clean the taper seat and the workpiece centre, verify correct point contact and apply pressure suitable for the machining operation. Insufficient pressure can generate instability, while excessive pressure may unnecessarily increase axial load and wear. The live centre should therefore be selected according to workpiece size, supported length, material, operation type, feed rate, depth of cut and required accuracy level.

The Nuova PTM CSF with extended point is a high-level technical solution for professionals looking for a robust and accurate live centre designed to improve the operating rigidity of the machine. The combination of large body, large bearings, extended central shaft and tracing point provides greater stability, improved accessibility and more effective control of machining conditions, with direct benefits for finished part quality and production process reliability.
