Description TRIBOS-R offers through its unique polygonal honeycomb structure and increased outer diameter, an optimal ratio between radial rigidity and damping, and provides the best dynamic run-out properties. Absolutely smoothly running and excellent shape and positional tolerances are the resulting benefits for a process reliable machining of the highest level. Field of application For milling centers/ optionally suitable for HPC/ HSC machining - drilling, reaming, milling, tapping/ thread milling and forming Advantages – Your benefits - Maximum radial rigidity. Maximum running smoothness and excellent geometric tolerances of the workpiece. - Excellent vibration damping. Prevents the machine spindle from damage. - Permanent run-out and repeat accuracy of less than < 0.003 mm. This assures best surface results due to a uniform cutting action and highest reproducibility. - Ultimate dynamic run-out properties. Excellent workpiece surface quality. - Precision balanced as standard with a balancing grade G2,5 at 25,000 rpm. Prevents the machine spindle from damage. - No moving parts and therefore maintenance-free - Exact axial length preadjustment - Broad compatibility, all customary shank types can be clamped (best results with cylindrical shanks h6 tolerances)
