A tool holder locking sleeve includes a tool sleeve; a pulling claw; an elastic component; and a pin, one end of a tool holder accommodating cavity inside the tool sleeve is provided with a tool holder installation opening, and another end is provided with a pulling claw installation portion; a tool holder clamping portion of the pulling claw is provided with a tool holder clamping surface, the pulling claw is hinged on a pulling claw installation portion, the elastic component connects the pulling claw and the tool sleeve, after the tool holder is inserted into the tool holder accommodating cavity, the pulling claw is driven by the elastic component so that the tool holder clamping portion is engaged into the tool holder to engage the clamping surface of the tool holder with the inner diameter of the tool holder.

A plurality of coolant channels extending from a coolant reservoir in the first section of the tool holder in a counter-clockwise helical path around the bore to a circular channel extending three-hundred and sixty degrees around the bore with a plurality of equally spaced openings in the front face of the tool holding section extending at an angle to the circular channel.

Provided is a tool magazine apparatus capable of preventing a phase error in attaching a tool to a tool holding gripper. A tool magazine apparatus includes: a magazine body having both front and rear racks each provided with tool holding grippers; a tool transfer device to take out a tool from the both racks and attach a tool to the both racks; a tool standby pot to hold a tool; and an intra-magazine tool change device to deliver a tool between the tool standby pot and the tool transfer device. The tool transfer device includes: a moving body disposed between the both racks; a base disposed on the moving body and being rotatable around an axis extending in the Z-axis direction; a transfer gripper attached to the base and being movable in a plane orthogonal to the Z-axis direction; and an air cylinder causing the transfer gripper to move.

An information processing system includes a request accepting unit for accepting a request for a selected pot to store a selected tool in a pot of a machine tool magazine; a storing unit for storing a setting value in each of a first cell and a second cell of the selected pot; a selecting unit for selecting the first cell or the second cell for the selected pot; a determining unit for determining a condition to store the selected tool in the selected pot on the basis of a size of each tool, a selected cell, and a storage condition of each of the pots; and an informing unit for informing when the condition of storage is not met.

A magazine includes: a first driving mechanism unit that rotates tool pots so as to position, at a first position, an identifier in a tool pot placed at a transportation position different from a magazine-side tool change position and so as to position, at a second position, an identifier in a tool pot placed at the magazine-side tool change position; and a second driving mechanism unit that moves a reading device so as to position the reading device at a third position when reading the identifier by the reading device and so as to position the reading device at a fourth position when transporting the tool pots.
