Live centres for lathes with compression are technical components used to support the workpiece during turning operations, ensuring stability, accurate centring and continuous axial contact while the part rotates. The product shown in the image is a revolving tailstock centre with cylindrical fitting and integrated axial compression, designed to compensate for small movements, load variations or positioning differences during machining. The compression stroke allows the centre point to adapt to the actual contact condition, maintaining controlled pressure on the workpiece and helping reduce vibration, instability and excessive marking.

This type of live centre is used on conventional lathes, automatic lathes, CNC lathes and machines dedicated to the production of cylindrical parts, shafts, pins, turned components and precision mechanical parts requiring reliable axial support. The revolving point follows the rotation of the workpiece, reducing friction and local overheating, while the compression system helps maintain constant contact even when slight positioning tolerances or micro-movements occur during the machining cycle.

The cylindrical fitting makes these live centres suitable for specific mounting systems, dedicated holders, special fixtures and machine-tool applications requiring a compact and precise support solution. The technical table shown in the image includes different cylindrical fitting diameters d1, together with D, E, H, L, S and compression stroke C dimensions. These values are essential for selecting the correct live centre according to the machine, available space, working load and workpiece geometry.

In precision machining, a live centre with compression is particularly useful when the stability of the component must be improved during turning, when deflection must be limited, vibrations reduced and dimensional repeatability increased. It is suitable for both production and maintenance departments working with free-cutting steels, alloy steels, light alloys, non-ferrous materials and components used in industrial, automotive and machine-tool applications.

For technicians, maintenance operators and lathe specialists, the correct choice of a live centre must take into account the cylindrical shank diameter, compression stroke, overall length, body dimensions and compatibility with the machine clamping system. Correct selection helps improve machining quality, protect the workpiece, maintain more regular support pressure and increase process reliability. In applications involving small turned parts or long and slender components, the live centre with compression contributes to reducing geometric errors, ovality, vibration and loss of accuracy during machining.

Tadaah presents this category as a technical solution for production departments, industrial maintenance, machine-tool builders and specialised workshops requiring reliable live centres for workpiece support during turning. Correct evaluation of the technical dimensions and operating conditions makes it possible to select the most suitable version for the machine and machining process, improving precision, service life and operational safety.
