Latest Patents
One of Kenji Yamada's latest patents is an apparatus for electrodischarge machining. This innovative electric discharge machining apparatus features a first movable body that moves along the Z axis, a ball screw, and a motor that causes the rotation of the ball screw. It also includes a nut attached to the first movable body, which threadingly engages the ball screw. A second movable body, capable of having the tool electrode attached, moves along the Z axis relative to the first movable body. The apparatus is designed to machine a workpiece by moving a tool electrode towards it while causing an electric discharge between the two. The linear motor in this apparatus includes a stator attached to the first movable body and a mover attached to the second movable body.
Another significant patent is for a spindle system for a diesink type electric discharge machine. In this design, the main spindle for the main spindle device is connected to a high rotor inertia, high output servo motor without passing through a speed reducer. The servo motor is equipped with a high-resolution encoder. This system allows for high-speed rotational control and precision angle division control, all accomplished by a single servo motor and encoder.
