Abstract: A tool-holder unit for machining block or slab materials is moveable above a working plane on which the block or slab material is laid. The tool-holder unit includes a spindle with a circular blade and a coupling assembly that couples a second machining tool with the spindle. The tool-unit further includes a tool-holder; a mechanical coupling device configured to rotationally integrate the tool-holder and the spindle; a first axial locking element configured to removably lock the tool-holder on the spindle; a substantially cylindrical shank extending from the tool-holder; a substantially cylindrical housing seat axially positioned in the spindle or a tool-holder coupling element; and a second axial locking element configured to removably lock the tool-holder in the spindle, the axial locking element being configured to removably lock the shank in the respective housing seat.

Abstract: A machine tool includes a turning position adjustment unit configured to control a turning drive unit so that, when a tool is transferred between a spindle and a grip, if an amount of sway of the tool is greater than or equal to a threshold value, a turret is turned and the amount of sway of the tool becomes less than the threshold value, and an origin point correcting unit configured to correct an origin point in accordance with a turning position of the turret acquired by a turning position acquisition unit, when the turret is turned by the turning drive unit so that the amount of sway of the tool becomes less than the threshold value.

Abstract: A tool changer includes a holding member having a tool change arm, a rotating mechanism for rotating the holding member, a forward/backward moving mechanism for moving the holding member forward and backward, and a controller controlling the mechanisms. A zero return controller determines whether the tool change arm is holding tools. When it is not holding tools, the tool change arm is rotated to a predetermined non-interference angle, the tool change arm is translated to a forward/backward movement zero point, and the tool change arm is rotated to a rotation zero point. When it is holding tools, the tool change arm is translated to a forward end, the tool change arm is rotated to position it on an expected path, and the tool change arm is moved along the expected path, thereby moving the tool change arm to the rotation zero point and the forward/backward movement zero point.

Abstract: The present disclosure relates to a tool carrier for an automatic tool changer. A tool carrier for an automatic tool changer according to the present disclosure includes: a base plate at which a center shaft is installed; a carrier unit installed at the center shaft to turn around the center shaft; a rotating pocket unit installed at the carrier unit to rotate and having a pin installed to protrude outward; a first cam block installed at the base plate and configured to perform a cam action with the pin to allow the pocket unit to rotate when the carrier unit turns from an initial position to the target position; and a second cam block installed at the base plate and configured to perform a cam action with the pin to allow the pocket unit to rotate when the carrier unit turns from the target position to the initial position.

Abstract: The present invention provides a tool changer which can be placed on the table of an existing machine tool, while utilizing the existing control computer of the machine tool to automate the tool changing process. This simplified tool changer allows the owner of an entry level machine tool to automate the machine tool at a relatively low cost and without many modifications to the machine tool as compared to current alternatives. The tool changer of the present invention requires no external power, no additional motors, and no modifications to the spindle of the machine tool.

Abstract: The spindle position orientation apparatus of a boring machine includes a main spindle attached to a casing and around which a cylindrical cam is fixed, a slider disposed on a guide rod to be movable right and left thereby rotating the cylindrical cam, and a limit switch which is opened and closed by a dog attached to a piston. The piston is disposed in a hydraulic cylinder fixed to the casing, one end of the piston is fixed to the slider and the dog is formed on the other end.

Abstract: A method for automatically removing a tool from a rotational shank shaft of a three-dimensional robot by indexing the shank shaft, disposing a tool tightening member provided in connection with the indexed shank shaft to a releasing device by movement of the robot, the releasing device being disposed during this operation inside the movement range of the robot; using the releasing device to release the tool; and removing the tool from the shank shaft of the robot by a movement of the robot.
