Abstract

A machining tool for speeding the transfer of workpieces among a plurality of spindles, downsizing the machine and facilitating maintenance, includes a plurality of spindles and a plurality of tool rests. The spindles are juxtaposed movably in the X-axis direction and each of the tool rests is disposed on an end surface of the spindle. The workpiece is machined by moving the spindle in the X-axis direction and moving the spindle and the tool rest relatively in the Z-axis direction. A workpiece holder between the neighboring two spindles and the moving ranges of the neighboring spindles in the X-axis direction are set to include a position where the spindles face the workpiece holder so that the workpiece may be transferred among the spindles and the workpiece holder.
