Abstract

See full text

A machine tool having a turning function and a milling function includes a spindle, a spindle housing supporting the spindle in a rotatable manner, a main clamp provided at the spindle, an auxiliary clamp provided at the spindle housing, and a double arm with a first gripper and a second gripper. The auxiliary clamp clamps a tool holder together with the main clamp during fixing a fixed tool. The double arm exchanges a tool holder grasped at the first gripper for another tool holder grasped at the second gripper by rotating and sliding movements. The auxiliary clamp is arranged at a position not interfering with the double arm that moves during exchanging tool holders. By such a configuration, a machine tool achieving a clamping force sufficient to withstand the load during a turning process, and that allows tool exchange in a short period of time, and a tool holder employed in such a machine tool, can be provided.
