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 are matched so that this high performance centre withstands vibrations in all machining situations. This high performance centre proves its strength for turning, CNC turning, cylindrical grinding and hard turning operations. Result: Excellent surface quality and the process-reliable compliance with tolerances.
