Claims

[Scope of utility model registration request]

In a machine tool equipped with an automatic tool changer that selects a desired tool from a tool magazine in which a plurality of tools are mounted at predetermined intervals on the outer periphery and mounts it on the tip of a spindle head that pivotally supports a spindle, The tool magazine is equipped with a honing tool that expands the grindstone radially outward by supplying hydraulic pressure therein via a spindle, and
A first valve body is provided at the upstream end of the hydraulic passage inside the honing tool and is urged outwardly by a spring to close the hydraulic passage, and a first valve body is provided at the downstream end of the hydraulic passage inside the spindle head by a spring. A second valve body is provided which is biased outwardly and closes the hydraulic passage, while one of the honing tool and the spindle head has a second valve body located opposite the first and second valve bodies, respectively. An automatic tool characterized in that first and second rods are erected to move the first and second valve bodies in the opening direction of the hydraulic passage by attaching a honing tool to the tip of the spindle. Machine tool with changing device.
