A portable cutting table, with SLIDE, and a TABLE, an adjustable BACKPLATE to support material being cut, and a BASE, all which support a JIG SAW, mounted upside down on the SLIDE, to allow easy control of cutting to Molding, Millwork, Stair Edging, angled cuts, with easy control of motor/blade speed, and easy visibility of cutting markings on the material being worked upon.

A circular saw cutting machine (1) includes a machine main body (10), an articulated robot (60), and a cutter stocker (70). A circular saw (5) is secured and interposed by a cutter clamp cylinder (CYL21) between a front end face (32) of the main spindle (21) and a cutter presser piece (50) with pins (33, 51) inserted in pin insertion holes (5b). When removing the circular saw (5), a hydraulic is switched over to cause the cutter clamp cylinder (CYL21) to perform unclamping so that the cutter presser piece (50) can be pulled out of the main spindle (21). When the articulated robot (60) performs cutter change, a main spindle motor (M10) and a brake (25) are controlled based on the rotation angle detected by a spindle stop position sensor (SE10) to stop the main spindle (21) in a predetermined home angle condition.

Provided is a tool holder or workpiece holder (100, 200) for coupling a tool to a drive spindle of a machine tool, said holder comprising a tool holding or workpiece holding section (110, 210) on which a clamping means (111, 211) for holding the tool is arranged, and comprising a coupling section (120, 220) for coupling to a tool interface (150, 160, 250, 260) of the drive spindle of the machine tool, in which the coupling section (120, 220) is configured as suitable for coupling both to a tool interface (150, 250) for receiving tool holders or workpiece holders that comply with a first standard and to a tool interface (160, 260) for receiving tool holders or workpiece holders that comply with a second standard.

A fixation device is adapted to be mounted with a machine tool and mounted to a machine bed. The fixation device includes a fixed seat, a magnetic unit, and at least one ejection unit. The fixed seat has a bottom surface and a plurality of grooves formed in the bottom surface. The magnetic unit includes a plurality of magnet blocks fixed respectively in the grooves and adapted to be magnetically positioned on the machine bed. The at least one ejection unit is mounted on the fixed seat, and includes an operating member and a supporting member. The operating member is operable to move the supporting member from a first position, where a bottom end of the supporting member is flush with the bottom surface of the fixed seat, to a second position, where the bottom end of the supporting member protrudes out from the bottom surface of the fixed seat.

Disclosed is a root end element for attachment to a root end of a wind turbine blade, a root end manipulator configured to manipulate a wind turbine blade, and a blade manipulation system comprising the root end element and the root end manipulator. The root end element being configured to support the root end of the wind turbine blade.

A universal holder for a workpiece to be machined including a serrated inclined plane and an equally serrated positioning block mounted in a movable manner along the inclined plane in an adjustment position and in a fixed manner along the inclined plane in a clamping position for a machining operation.

A tool holder for a machine includes a frame and an actuator that can be moved from a retracted state to an extended state and back. The frame includes a hook shaped recess having an opening and a cut out arranged at a distance from the hook shaped recess so that a front bracket pin of a tool can releasably connect to the hook shaped recess by entering the opening and a rear bracket pin of the tool can releasably connect to the cut out. The actuator is fixedly connected to the frame with one end. The actuator includes a locking element that is designed to change the shape of the cut out in the extended state of the actuator. The actuator includes a securing assembly designed to reduce the size of the opening of the hook shaped recess in the retracted state of the actuator. The rear bracket pin can enter the cut out in the retracted state of the actuator and the front bracket pin can enter the hook shaped recess in the extended state of the actuator.
