The Nuova PTM CSF live centre with interchangeable point and locking ring is a professional lathe accessory designed to support the workpiece during turning, finishing and between-centre machining operations where high rigidity, geometric accuracy and machining stability 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, form errors and dimensional defects on the finished component.

This version stands out thanks to its interchangeable point and front locking ring, a technical solution designed to improve ease of use and operating flexibility. The replaceable point allows intervention in case of tip wear or adaptation to specific machining requirements, maintaining correct contact with the workpiece centre over time. The locking ring makes the point assembly easier to manage and supports practical operations such as mounting, inspection and point replacement, especially in departments where the live centre is used intensively.

The CSF series differs from conventional live centres thanks to its large-section body, designed to accommodate large-size bearings. This feature increases the strength of the rotating assembly and makes the live centre suitable for machining operations involving heavy loads and high axial thrust. A larger body provides greater structural stability and allows the live centre to maintain more effective support on the workpiece even under demanding operating conditions.

One of the most important benefits of the CSF construction is the ability to move 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, reduces vibration tendency and improves cutting stability. The result is a more controlled machining process, with direct benefits for surface finish, dimensional accuracy and process repeatability.

In precision machining, the rigidity of the support system is essential to limit unwanted taper, ovality, chatter marks, cutting instability and geometric variations on the workpiece. The CSF live centre with interchangeable point and locking ring helps keep the workpiece stable during rotation and allows the operator to work with greater confidence during both roughing and finishing passes.

The construction with a central shaft as long as the body is another distinctive technical feature. This configuration increases the internal structural continuity of the live centre and distributes loads more effectively during operation. Thanks to this design, the live centre can withstand high working loads and high axial thrust, offering higher performance than many conventional solutions with the same Morse taper.

From an application point of view, the Nuova PTM CSF with interchangeable point and locking ring is suitable for machining shafts, pins, bushings, cylindrical components, turned parts and mechanical workpieces requiring accurate support between centres. It is used in machine shops, turning departments, production areas, industrial maintenance, machine construction, the automotive sector and precision engineering, where workpiece position control and final machining quality are essential parameters.

For correct use, it is recommended to check the compatibility of the Morse taper with the machine, carefully clean the taper and mounting seat, inspect the condition of the interchangeable point and ensure that the workpiece centre is clean, intact and correctly machined. Tailstock pressure must be appropriate for the operation: insufficient pressure may cause instability and vibration, while excessive pressure can unnecessarily increase axial load and point wear. The live centre should therefore be selected according to material, workpiece length, diameter, feed rate, depth of cut, operation type and required accuracy level.

The Nuova PTM CSF live centre with interchangeable Tip and locking ring is a technical solution for professionals looking for a strong, accurate and practical support for high-quality turning operations. The combination of large-section body, large bearings, extended central shaft, front locking ring and replaceable point provides greater rigidity, better machining control and higher operating efficiency in lathe applications.
