A machine tool according to the present invention is provided with a door opening/closing device including a movable door, a door opening/closing drive motor configured to drive the movable door, a power transferring mechanism configured to transfer power of the door opening/closing drive motor to the movable door. The machine tool includes a disturbance torque estimation unit configured to estimate a disturbance torque applied to the door opening/closing drive motor at an opening/closing operation of the movable door, a torque comparison unit configured to compare the disturbance torque estimated by the disturbance torque estimation unit to a predetermined first upper limit and a predetermined first lower limit, and a motor stop unit configured to stop the opening/closing operation of the movable door when the torque comparison unit determines that the disturbance torque is larger than the first upper limit or smaller than the first lower limit.

The invention relates to a tool magazine (1) for a manipulator (4) comprising a plurality of tool holding fixtures (2) which are distributed in a preparation area (7), especially in a substantially vertical preparation plane (11). The tool magazine (1), on one side (9) of the preparation area (7), comprises a first access opening (10) facing the manipulator (4) and, on the other side (15) of the preparation area (7), a second access opening (16) facing an operator (13) and the first access opening (10) is associated with a first protective device (17) and the second access opening (16) is associated with a second protective device (18).

The present invention relates to a machining apparatus for machining workpieces. These workpieces can be, merely as an example, workpieces of wood, wood materials, synthetics or the like. The machining apparatus comprises a machine bed (10) and a machining unit (20) movable along the machine bed (10), in the housing (21) of which a machining aggregate (25) is provided, at least one sensor (30a, 30b, 30c, 30d; 40) mounted on the housing (21) of the machining unit, which is provided for monitoring a travel movement of the machining unit (20), an operating element (50a, 50b, 50c) being provided on the housing (21) of the movable machining unit to input an operating command for the machining unit (20), in particular a command to start or stop.

A machining system comprises a machine tool, a machine tool controller that controls the machine tool, an auxiliary device that assists the machine tool, and an auxiliary device controller that controls the auxiliary device. The machine tool and the auxiliary device work cooperatively for machining. The machining system comprises a signal management unit that receives a first signal and a second signal. The first signal indicates information about the machine tool as a criterion used for determining whether the machine tool and the auxiliary device are operable or inoperable. The second signal indicates information about the auxiliary device as a criterion used for determining whether the machine tool and the auxiliary device are operable or inoperable. The signal management unit outputs a third signal indicating an operable state or an inoperable state of the machine tool and the auxiliary device to the machine tool controller and the auxiliary device controller based on the first signal and the second signal.

A blade mounting and dismounting jig is provided for mounting a blade on and dismounting a blade from a flange of a cutting apparatus which includes a boss, a blade mount for mounting the blade fitted thereover, the flange having an annular end face for supporting the blade thereon and being fixed to a distal end of a spindle, and a holder that cooperates with the flange in gripping and securing the blade in position. The blade mounting and dismounting jig includes a cylindrical jig body, a grip coupled to the jig body and having a diameter larger than the jig body, a plurality of first air ejection ports defined in a distal end portion of the jig body, a plurality of second air ejection ports defined in the jig body at a juncture between the jig body and the grip.

In the machining of a stationary workpiece by means of a rotating tool head, the risk of damages to the workpiece by the chips can be minimized and the removal of the chips can be simplified if a chip collector and a stationary nozzle for fluid are respectively provided.

A machine tool includes a shielding cover, a door, and an automatic tool changer. The shielding cover covers a machining space of a main spindle. The door opens and closes an opening disposed in the shielding cover. The automatic tool changer automatically exchanges a tool to be mounted to the main spindle. The automatic tool changer exchanges the tool to be mounted to the main spindle by turning an arm in a plane perpendicular to the main spindle so as to cause the arm to enter into and exit from the machining space. The arm is configured to grip and release the tool. The turning of the arm is synchronized with the opening and closing movement of the door.

Described herein is a work cell for machining operations carried out via a laser head, the work cell including:at least one working area (20, 40) designed to 5 receive the pieces on which to carry out laser machining; and a lateral covering (60) and a top covering configured for separating at least partially said working area from the outside.10 The work cell is characterized in that:it comprises an internal divider (18) that defines, together with said lateral covering, a first working area (20) and a second working area (40) separated from one another by said divider; and 15 said top covering (22) is selectively mobile between a first position over said first working area (20) and a second position over said second working area (40).

A machine tool capable of restraining dirt on the footstool and improving setup efficiency. The machine tool includes a machine body having a splash guard surrounding a machining area and a door capable of closing an opening of the splash guard. A footstool is kept mounted on the machine body changeably in place with respect to the machine body. The footstool kept mounted on the machine body is capable of being in a place on an outside of the machine body when the door is closed. The footstool kept mounted on the machine body is capable of being brought to a setup place inside the machining area from the outside of the machine body through the opening when the door is open.
