A controller of a cutting device includes a first reference point detection processor detecting an actual position of a first reference point on a top surface of a first protrusion of a magazine, a second reference point detection processor detecting an actual position of a second reference point on a top surface of the second protrusion of the magazine, a sensor offset calculation processor calculating an offset of an actual position of a tool sensor of the magazine with respect to a designed position of the tool sensor based on the first reference point and the second reference point, a stocker offset calculation processor calculating an offset of an actual position of the stocker of the magazine with respect to a designed position of the stocker based on the first reference point and the second reference point, and a movement control processor controlling a movement mechanism based on the offset of the tool sensor and the offset of the stocker.

A workpiece processing machine includes a separation device for dividing an operating space into a processing region and at least one additional operating region, a laser processing head configured to process the workpiece, and a rotary workpiece changer having a rotatable workpiece support for transporting the workpiece between the processing region and the at least one additional operating region by an opening. The rotatable workpiece support has a protection wall configured to shield the at least one additional operating region with respect to the processing region. The separation device has a protection element movable between a processing position and a transport position and configured to be in abutment with the protection wall in the processing position to close the opening and spaced apart from the protection wall in the transport position. A spacing between the processing position and the transport position is adjustable based on a dimension of the workpiece.

The present invention provides machine tool having a door of which the position is changed between the time of machining and when nothing is being machined, and where the moving speed of the door can be changed. The machine tool is provided with: a drive unit that can move the door; a control unit that can control the drive unit for moving the door; a safety signal input unit that takes in a safety signal from the outside of the machine tool; and a door opening and closing speed setting unit that can set the moving speed of the door to a first moving speed in the case where a safety signal is inputted into the signal input unit or to a second moving speed in the case where no safety signal is inputted, and is characterized in that the first moving speed is higher than the second moving speed.

The machine tool includes a workpiece carrier assembly arranged for horizontal movement in parallel to a horizontal axis and a tool carrier configured for carrying at least one tool for machining at least one workpiece by rotating the tool. The workpiece carrier assembly or the tool carrier is displaceable between an operative position in which a workpiece carrier is facing the tool carrier, and at least one inoperative position. The workpiece carrier is arranged to be rotatable to allow for a modification of the angular position of the workpiece in relation to the tool carrier.

The present invention provides a machine tool provided with a cover body having a simple structure, excellent operability, and low manufacturing cost. A tool post movement region one-side-closing cover part (9) for closing a tool post movement region open part (8) is configured so as to be: capable of expanding and contracting in a horizontal movement direction of a tool post (3); arranged facing the tool post (3); elongated by urging means (10) to press against the tool post (3) in a relatively slidable manner and close the tool post movement region open part (8); expanded and contracted by movement of the tool post (3) to hold the tool post movement region open part (8) in a closed state; and provided unconnected to the tool post (3) so that the tool post (3) is relatively slidable with respect to the tool post movement region open part (8) is held in a closed state.

A gear manufacturing machine for which a machining tool detachably attached to a tool spindle is exchanged by means of an automatic tool changer, wherein the automatic tool changer is provided with: tool holding means for detachably holding a machining tool to be exchanged; moving means for moving the tool holding means in a direction parallel to the axial direction of the tool spindle; and rotating means for rotating the tool holding means.

Provided is a vertical machining center including: a splash cover fixed to a base, the splash cover defining a machining chamber to enclose a machining zone; a column vertically standing on the base; a Z-axis guiding rail disposed on the column and being vertically directed toward the base, the Z-axis guiding rail partially exposed to the machining zone; a Z-axis driving device disposed in the column, the Z-axis driving device partially exposed to the machining zone; a spindle head to be driven vertically by the Z-axis driving device; a spindle head opening formed in the splash cover so that the spindle head can pass through the spindle head opening; and an extendable cover provided between an edge of the spindle head opening and the spindle head and configured to cover parts of the Z-axis guiding rail and the Z-axis driving device, the parts being exposed to the machining zone.

The clear view screen includes two transparent disks, of which one is fixed and the other rotates. A camera (28), which in any case looks through the rotating disk (18), is arranged between the two disks or on the side of the fixed disk facing away from the space to be observed. The camera is supplied with power via the power supply unit of the driving device, so that continuous operation is also possible when the camera is arranged in a space not accessible for maintenance, for example between the first and second disks or between the first disk and an uninterrupted separating wall.

A machine tool including a tool holding unit and a workpiece holding unit includes: a clamper to which a part of a sub-tool, which is a separate tool from a main tool held by the tool holding unit alone, can be detachably connected; an attachment/detachment unit to which another part of the sub-tool can be detachably connected; a tool spindle that moves the clamper; an in-machine robot that moves the attachment/detachment unit; and a controller that controls driving of the tool spindle and the in-machine robot, to execute machining of a workpiece by the sub-tool.

A live tool system having a live tool and a collar surrounding a rotating shaft or a rotating cutting tool of the live tool. The collar houses at least one sensor capable of monitoring an operating condition proximate to the cutting tool during a cutting operation. Example operating conditions including temperature and vibration. The system also includes a wireless transmitter in communication with the at least one sensor for transmitting a signal for use by a machining center controller.
