Our know-how, our experience and our background in the high precision manufacture of our centres guarantee the features of our own products at the highest level. The BRUCKNER guarantee for standard dead centres Out-of-roundness ≤ 0.8 µm. We supply standard dead centres and special designs with out-of-roundness ≤ 0.3 µm. Test report on request. Roundness out-of-roundness on carbide ≤ 0.8 µm High concentricity accuracy of the 60° point to the taper shank according to BRUCKNER works standard = the eccentricity has been reduced by up to 70% compared with DIN 806 Top-quality carbides safely fixed in the base material sa•co® – the safety core maximum safety through the integrated safety core (forms V, GV, Z, GZ and HZ with carbide diameter 20-45 mm) Regrinding line marking the useful end of the centre Hardened taper shank the taper is case hardened for protection from damage Taper shank tolerance deviation of taper AT4 to DIN 228 (gauge accuracy) 1 2 3 4 5 6 7 3 5 1 2 4 6 7 Carbide Dead Centres
