Dynamic Characteristics of Lathe Using Concrete Bed

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