The Nuova PTM CNE/R live centre is a professional solution for turning and finishing operations on conventional lathes, centre lathes and CNC machines, including applications at high rotational speeds. This version is equipped with an interchangeable point, a particularly useful configuration when greater flexibility is required and the live centre must adapt to different operating conditions, workpiece geometries or maintenance needs.

The interchangeable point allows the tip to be replaced when worn or when the application requires a contact geometry better suited to the part being supported. This feature makes the live centre more versatile than a fixed-point version, especially in production departments where different workpieces, materials or batches with changing requirements are machined. The main advantage is the ability to maintain accurate workpiece support over time, reducing machine downtime caused by point wear and improving operating continuity.

The CNE/R series is suitable for medium-duty applications and features an extremely compact and rigid external body. This structure supports stable operation while the workpiece is rotating and helps reduce vibration, deflection and loss of accuracy during machining. The live centre can be used to support shafts, pins, bushings, cylindrical parts and turned mechanical components, both in light roughing operations and finishing passes.

The internal assembly is built with a carefully engineered system of bearings and thrust bearings mounted in ground seats and protected by oil seals. This construction ensures smooth and stable rotation while maintaining good axial and radial support capacity, depending on the selected model. The quality of the internal assembly is essential to ensure precision, service life and reliability in continuous or repetitive machining operations.

A key feature of the CNE series is the WPS - Water Protection System, designed to protect the internal components from dust, chips and coolant penetration. This protection is very important in modern workshops, where coolant and machining residues may affect bearing smoothness and live centre accuracy over time if the internal parts are not properly shielded.

The internal lubrication system uses permanent grease, reducing routine maintenance requirements and making the live centre suitable for daily workshop use. During the first working hours, a slight grease leakage may occur due to the settling of the internal lubrication. In general, the live centre does not require frequent maintenance, although periodic inspection is recommended according to the intensity of use, working environment and exposure to coolant, dust or chips. During operation, the body temperature may exceed 60°C, which should be considered normal in working conditions.

With a Morse taper of choice, the Nuova PTM CNE/R is a robust, accurate and cost-effective solution for machine shops, turning departments, toolrooms and production facilities requiring a reliable live centre for medium-duty machining. The interchangeable point improves practical use and makes this product particularly suitable for users who need consistent performance over time, easy point replacement and a strong balance between performance, durability and price.
