A lathe base assembly is disclosed that decreases vibration and increases thermal stability in a lathe utilizing either a cast iron or composite base. Two separate pairs of rails mounted offset from each other are provided for mounting a secondary spindle and a tool turret, respectively. Vibration from the tool turret caused by the machining operation is thus isolated from the secondary spindle (and vice-versa). If a second tool turret is provided with the lathe, a third separate pair of rails can also be provided for mounting the second tool turret to increase vibration isolation. If a cast iron base is provided, cavities can be provided in the base for filling with a vibration damping material, such as a polymer composite. Alternatively, the base can be constructed from a composite material, and especially a polymer composite.

Abstract

A lathe base assembly is disclosed that decreases vibration and increases thermal stability in a lathe utilizing either a cast iron or composite base. Two separate pairs of rails mounted offset from each other are provided for mounting a secondary spindle and a tool turret, respectively. Vibration from the tool turret caused by the machining operation is thus isolated from the secondary spindle (and vice-versa). If a second tool turret is provided with the lathe, a third separate pair of rails can also be provided for mounting the second tool turret to increase vibration isolation. If a cast iron base is provided, cavities can be provided in the base for filling with a vibration damping material, such as a polymer composite. Alternatively, the base can be constructed from a composite material, and especially a polymer composite.
