A LIVE CENTRE FOR A TAILSTOCK OF A LATHE, A LATHE AND A METHOD FOR CONTROLLING VIBRATION OF A LATHE SYSTEM

摘要

A live centre for a tailstock (100) of a lathe, a lathe and a method of operating the same, in which the live centre has a body (110), a rotating part(120); and a radial bearing (130) configured to rotatably support the rotating part to the body. The radial bearing is stiffness adjustable in the radial direction for control of vibration characteristics of the lathe during machining by adjusting axial compression force that effects over the live centre. The vibration characteristics can be estimated in advance by simulation.
