Bruckner steel and carbide Dead Centres are of the finest materials to tolerances narrower than DIN806 and DIN228. Standard Centres have tip runout within 0.001 mm and Special Accuracy Centres runout within 0.00025 mm. Shanks are hardened and ground to fine tolerances and most standard/TC tipped centres are available in length options for each Morse taper.
Pressure Indicating live centres (spring loaded centres) show actual tailstock pressure by coloured bands on the live centre spindle. Use these centres when face driving where they are invaluable to see the axial force being applied to the component end; or when machining long/slender work to allow for thermal expansion.
The new “T” Line range of centres for CNC lathes. which include spring loaded/compensating centres for CNC lathe tailstocks and turrets, plus compensating centres with CAPTO shanks. BRUCKNER “bullnose” or “cone” live centres are available up to 300 mm maximum diameter with 60 or 75 degree included angles and with standard mounting tapers from Morse 2 to Morse 6. Standard maximum runout is 0.007 and ZAG special accuracy versions have runout within 0.003 mm.
BRUCKNER and BRUCKNER-BoKo face drivers enable savings to be made on many shaft turning applications. Parts are driven from one end face only so the whole profile is accessible from one end.
