Abstract
This paper describes the dynamic characteristics of a lathe using a concrete bed. The concrete has attracted special interest as a structural material for its low cost of production and good damping properties. In this paper, the effects of the concrete bed on the vibration and noise levels of the structure and the dynamic stiffness of a work-spindle system are mainly investigated. From the results, it is pointed out that the bed made of ferrite resin concrete, which is a new high damping material and consists of ferrite powder and polyester resin, has low noise and vibration levels as compared with the welded steel bed. However, the damping in the fundamental resonant frequency of the work-spindle system is not affected by the structural material.
