Abstract: A pair of lead wire drawn from a voice coil is fixed to a land portion of a pair of terminal member by thermo-compression bonding. The pair of terminal member is integrally formed with the frame by insert molding. The frame made of synthetic resin has a pair of circular holes on the back side of the land portion to expose the land portion to the back space of the frame. In thermo-compression bonding, a supporting jig is pressed against the back side of the land portion via the circular hole. Thereby, generated heat is immediately transmitted to the supporting jig, preventing melting part of the frame around the land portion. Pressing force of a thermo-compression jig is received by the supporting jig, preventing sinking of the land portion in the frame.

Abstract: Every time the cumulative number of revolutions of a spindle rotating motor reaches a cumulative number of revolutions set in a data table, a CPU reads out, from a data memory section, moving positions of a workpiece and tool at the reached cumulative number of revolutions and the next cumulative number of revolutions, and a spindle rotational speed instruction value at the reached cumulative number of revolutions. The CPU sets the reached cumulative number of revolutions as a start point and the next cumulative number of revolutions as an end point, and divides the interval between the start and end points at predetermined timings. The CPU determines moving positions of the workpiece and tool at divided timings on the basis of the readout moving positions of the workpiece and tool. The CPU outputs the spindle rotational speed instruction value as a spindle rotational speed instruction signal to a reference spindle rotational speed setting circuit to control the rotational speed of the spindle rotating motor.

Abstract: A bobbin unit includes a base portion and a coil winding portion on which a conductor is wound. A hole is formed in a central part of the base portion to allow an armature to pass through. Coil side terminals to which ends of the conductor are fixed and signal input terminals to which an external signal is entered are provided at opposite ends of the base portion with the hole located in between. The coil side terminals are electrically connected to their corresponding signal input terminals inside the base portion. A coil is formed on the coil winding portion by winding the conductor. The ends of the conductor are wound around the respective coil side terminals and fixed thereto by arc welding. Since the conductor is electrically connected to the signal input terminals when the ends of the conductor are fixed to the coil side terminals, connection of the ends of the conductor constituting the coil to the signal input terminals is made easy. Furthermore, the length of lead wire portions between the coil and the coil side terminals is shortened, making it possible to prevent breakage of the conductor between the coil and the coil side terminals.

Abstract: A technology capable of improving the accuracy of true-circular machining while avoiding an occurrence of intermittent cutting. A control unit of a machine tool determines an intermediate center position (Pi) in the moving direction for each divided rotation angle (E) smaller than a single rotation of the spindle and an intermediate eccentric radius (ri) around the intermediate center position (Pi) according to an initial position (Po) of the cutting edge in contact with the workpiece in the moving direction, the eccentric center position (Pc), and the eccentric radius (rc) to keep the cutting edge in contact with the workpiece as the moving object moves in the moving direction within a predetermined maximum feed speed (F) until a true-circular machining around the eccentric center position (Pc) is complete on the workpiece.

Abstract: A lathe includes a spindle rotatable on a spindle axis, a tool post to which a tool is attachable, an X1-axis ball screw extended in an X1-axis direction perpendicular to the spindle axis and capable of moving the tool post in the X1-axis direction, and an X1-axis support bearing provided on an end of the X1-axis ball screw with respect to the X1-axis direction to restrict movement of the X1-axis ball screw in the X1-axis direction. The tool post is provided with an X1-axis ball screw nut engaged with the X1-axis ball screw. The X1-axis ball screw nut is movable in the X1-axis direction according to rotation of the X1-axis ball screw. The direction that the X1-axis ball screw nut approaches the X1-axis support bearing faces the same direction as the direction that the tool cuts into the workpiece.
