The revolving tailstock centre without compression Type 172600 F is a precision component designed to provide axial support to the workpiece during turning operations on single-spindle lathes, multi-spindle lathes, automatic lathes, conventional mechanical lathes and CNC lathes. Its function is to keep the workpiece centred and stable during rotation, reducing deflection, vibration and instability that may affect machining quality, concentricity and dimensional repeatability.

This version is manufactured without compression, so it works with rigid and direct support on the workpiece, without any axial absorber stroke. It is suitable when the contact position must remain constant and when the machining process requires a stable, precise and repeatable live centre. Compared with compression versions, the live centre without compression is especially suitable for operations where the rigidity of the machine-fixture-workpiece system is a priority and where the geometric control of the component must be maintained with maximum consistency.

Type 172600 F is characterised by its larger body dimensions, with D= 43 mm, E= 18 mm, H= 43 mm, L= 46 mm and S= 21 mm in the versions shown in the table. The range includes several cylindrical fitting diameters d1, from d1= 19.05 mm up to d1= 32 mm, allowing use on different machine configurations, dedicated holders and special fixtures. The cylindrical fitting allows mounting in precise seats where a Morse taper is not used, but a direct, stable and controlled cylindrical coupling is required.

This live centre is suitable for machining shafts, pins, bushes, cylindrical parts, automotive components, turned parts and mechanical workpieces requiring reliable axial support during roughing, finishing or secondary operations. The standard point provides effective support in most turning applications, while the robust structure helps ensure stability and operating continuity even in repetitive cycles or demanding industrial machining.

For technicians, maintenance operators and turning specialists, the correct choice of the live centre must consider the d1 cylindrical fitting diameter, body dimensions, length L, dimension S and compatibility with the machine mounting seat. Proper selection improves surface quality, reduces concentricity errors, limits ovality and maintains regular support pressure on the workpiece.

This category is intended for machine shops, precision engineering companies, preventive and corrective maintenance departments, machine-tool builders, turned-part manufacturers and automotive industries. Tadaah offers the revolving tailstock centre without compression Type 172600 F as a technical solution for applications requiring precision, rigidity, reliability and long service life in workpiece support during turning.
