Abstract
Official abstract text for this publication.
A machine tool includes a slide table supported by an upper portion of a main body of the machine tool so as to be horizontally slidable, a rotary table provided on the slide table so as to be rotationally indexable about a vertical axis extending in the direction that is orthogonal to the direction of horizontal slide movement of the slide table, and a motor provided in the slide table to rotate the rotary table. A housing space is formed in the main body to house a lower portion of the slide table. At least a part of the motor provided in the slide table is placed in the housing space.
First claim
Opening claim text (preview).
What is claimed is: 1. A machine tool comprising: a slide table supported by an upper portion of a main body of the machine tool so as to be horizontally slidable; a rotary table provided on the slide table so as to be rotationally indexable about a vertical axis extending in a direction that is orthogonal to a direction of horizontal slide movement of the slide table; a pair of guide rails provided on the main body and disposed opposite to each other on outside of a housing space to support the slide table so as to be horizontally slidable, and a pair of motors provided in the slide table to rotate the rotary table, wherein the housing space is formed in the main body to house a lower portion of the slide table so that at least a part of the pair of motors provided in the slide table is placed in the housing space, the pair of motors are disposed point-symmetrically about the vertical axis to rotate the rotary table, and the pair of motors are aligned with one another in the slide table in a direction extending parallel with a sliding direction of the slide table. 2. The machine tool according to claim 1 , wherein at least one driving unit, configured to drive the slide table horizontally, is rotatably disposed in the housing space.
