22 High Performance Live Centres LK Series High concentricity accuracy tested under axial load guaranteed by test report Through-hardened alloy tool steel centrepoint Seal ring protects the bearings from dirt and coolant Precision bearings bearings seats of housing and centre spindle are precision ground and matched to the bearings. Maintenance-free due to permanent lubrication Housing of high tensile alloy tool steel. Housing head and shank are case-hardened for protection against damage 1 2 3 4 5 LK Series – with superior stiffness This high performance live centre was developed for use with advanced turning and grinding technology. With a short design, the bearings and pitch of the bearings distance are matched so that this high performance centre withstands vibrations in all machining situations. The bearings are designed for higher r.p.m. Result Excellent surface quality Longer tool life Improved machine tool efficiency Two types for MT4 and MT5 Slim design for light machining With stronger bearings for normal to heavy machining 1 2 3 4 4 5 Produced according to BRUCKNER WORKS STANDARD (page 8)
