ABSTRACT:
A tool gripper which holds a plurality of tools in arm portions thereof. The gripper is provided in a tool rack type magazine that accommodates tools used in machine tools, and each of the arm portions of the tool gripper is arc-shaped and opened in an obliquely upward direction so that a tool entrance of the arm portion faces obliquely upward over a tool holding portion of the arm portion. The tool gripper is obtained by processing a continuous, elongated plate with laser or press to form the arm portions, and such a plate can be obtained by overlaying a plurality of thin plates in the thickness direction into a sandwich structure.
