The robot controller (50) controls the multi-joint robot (40) in accordance with the program. Operation panels (22, 24) are respectively provided with switch keys (22c, 24c) operated to execute the wait position return program stored in the memory (450) so as to operate the multi-joint robot (40).
Abstract: When machining of a circumferential groove is performed by advancing a cutting tool which is attached to a rotating shaft extending to an inner side from an outer side of a rotating work into the work in a depth direction, the rotating shaft is downwardly inclined toward the inner side of the work at a predetermined inclination angle, a trajectory of a cutting edge within the work is arranged to be an ellipse of which minor axis is oriented in the radial direction connecting a deepest point thereof and the center of the work as viewing in a plane view, and the work is cut as lowering the cutting tool until reaching groove depth of a machining target while maintaining the inclination angle, so that deviation occurring in a direction of an axis toward a work center axis in parallel to a work face from a point on the work face on which the deepest point is projected or an axis of the rotating shaft of the cutting tool projected on the work face can be arbitrarily set.
Abstract: A control panel 21 has a display screen 22. An operator turns a low-thrust pressing key 28 ON in the menu key group 26 displayed on the display screen 22. In this state, the operator turns an operating dial 32 of a manual pulse generator 31, thereby causing an encoder 34 to generate pulses. When the encoder 34 outputs a pulse signal as a command signal, and a servomotor 17 is driven in accordance with the command signal, the tailstock is advanced. With the distal end of a tailstock center contacting a center hole of the workpiece, the operator turns the operating dial 32, thereby finely adjusting the drive torque of the servomotor. Accordingly, the thrust of the tailstock center is finely adjusted, so that the tailstock center is pressed against the workpiece by a low thrust.

Abstract: A laser processing unit includes a torch that is automatically mounted on a processing head. The torch has an assist gas chamber and a balance chamber, and the assist gas is supplied to the chambers. Constantly, equal pressures act on the both chambers, and an upward first force and a downward second force that act on a lens holder offset each other because pressure reception areas are equal. Gas is supplied to a gas spring chamber to provide a constant upward force to the lens holder. A driving device has an arm driven by a servomotor. The arm is in contact with a pin and the lens holder is moved to a predetermined position for automatically adjusting a focus position FC of a collective lens.

Abstract: An NC control unit 100 includes a touch panel display device 155 through which a barrier canceling command is input and a machining control section 160 that performs an interference check for interference between a milling tool 70 and a chuck 58 and jaws 60. When the machining control section 160 determines that interference occurs and stops movement of a tool rest 54, the machining control section 160 writes the barrier canceling command that commands cancelation of the interference check for a process of a machining program where the interference has been determined based on manipulation of the display device 155. When the machining program including the barrier canceling command is carried out to machine subsequent workpieces, the machining control section 160 omits the interference check for the process corresponding to the barrier canceling command.
Abstract: The present invention reduces or prevents bank occurrence with higher accuracy of groove shape to be machined as being cut and ensures sufficient groove depth while avoiding interference with a work even when a small-diameter tool is used.

A composite working lathe (1) includes a first workpiece headstock (20) placed on a bed (10). A chuck (24) of a workpiece spindle (22) is rotated as holding a workpiece (K1). A tool headstock (100) arranged at a carriage (50) is rotated about B-axis while being linearly moved in the directions of X-axis, Y-axis and Z-axis. The tool headstock (100) operates a mill tool (110) and includes a comb-shaped cutting tool rest (150) having turning tools attached at the opposite side of a housing in a comb-shaped manner, so that turning processing can be performed with tool indexing in a short time.

Abstract: A tool holder is provided that prevents chattering in a large-sized cutting tool. A tool holder 1 includes an anti-vibration device provided in a radially outer portion of a body. The anti-vibration device has a ring-shaped first anti-vibration member and a second anti-vibration member. The anti-vibration device is fixed to the body together with a cutting tool T1 by means of a bolt. Four O-rings are arranged on both sides of the first anti-vibration member, and the damper property is adjusted by pressing a pressing plate with adjuster bolts. An appropriate gap is formed between the first anti-vibration member and the body and between the first anti-vibration member and the second anti-vibration member.
