The revolving tailstock centre without compression Type 172300 F is a precision component designed to support the workpiece during turning operations on single-spindle lathes, multi-spindle lathes, conventional mechanical lathes and CNC lathes. Its main function is to provide axial support to the rotating part, maintaining stable centring and contributing to machining quality, especially when the workpiece length, diameter or clamping condition requires additional support.

This version is manufactured without compression, meaning that it has no axial absorber stroke. Contact with the workpiece is direct and rigid, making it suitable for applications where a constant, precise and repeatable support position is required. The absence of compression is particularly useful in machining operations where geometric control, rotational stability and system rigidity are essential to reduce vibration, deflection, concentricity errors and dimensional variations.

The cylindrical shank allows mounting in dedicated seats, live-centre holders, special fixtures and machine configurations requiring a precise cylindrical coupling. The technical dimensions shown, such as d1, D, E, H, L and S, make it possible to select the correct version according to the shank diameter, available space, point position and machine-tool compatibility. The range includes several d1 diameters, allowing use on different turning systems and industrial setups.

The live centre is designed to ensure reliability, wear resistance and consistent performance even under demanding working conditions. The ground body supports accurate fitting and mounting stability, while the standard 60° point is suitable for most turning applications. When specific geometries, special materials or different contact conditions are required, interchangeable points can be used to adapt the live centre to the workpiece and machining process.

This category is suitable for machine shops, production departments, maintenance teams, machine-tool builders, automotive companies, precision engineering, turned-part production and industrial machining of shafts, pins, bushes, cylindrical parts and metal components. In automatic and multi-spindle lathe applications, the revolving tailstock centre without compression helps maintain regular workpiece support during repetitive cycles, improving process stability and dimensional repeatability.

To obtain the best performance, it is important to check compatibility between d1 diameter, mounting seat, length L, dimension S and point position in relation to the workpiece. Correct selection improves surface quality, reduces machining instability and preserves the accuracy of the machine-fixture-workpiece system. Tadaah offers this category as a technical solution for turning professionals requiring reliable, precise live centres suitable for industrial machining where rigidity, durability and accuracy are essential requirements.
