  • Waterproof Structure in a Tank
    Publication number: 20100277853
    Abstract: A waterproof structure in a tank. The circuit board required for discharge machining in the tank is disposed outside the tank. The inner wall of the tank is provided with a waterproof component with a downward opening. The circuit board along with other elements is connected to an electrode contact disposed in the waterproof component. When the machining liquid is full, the air pressure in the air storage space of the waterproof component balances with the liquid pressure at the opening. This prevents the machining liquid from spilling onto the electrode contact and resulting in the bypassing circuit effect. Moreover, the waterproof component can be used at the electrode contact of each base of the conductive platform, providing the same protection.

  • DISPLACEMENT COMPENSATION CONTROL METHOD AND MODULE FOR AN OBJECT MOUNTED MOVABLY ON A DRIVING ROD UNIT
    Publication number: 20100249982
    Abstract: In a displacement compensation control method and module for an object mounted movably on a driving rod unit and movable between first and second positions relative to the driving rod unit during processing, a detecting unit determines a displacement amount of a free end of the driving rod unit from a reference position in an axial direction of the driving rod unit as a result of thermal deformation of the driving rod unit during high-speed rotation. A control unit controls the driving rod unit to rotate based on the displacement amount so that the object moves between first and second compensation positions relative to the driving rod unit. A distance between the first position and the first compensation position, and a distance between the second position and the second compensation position are equal to the displacement amount.
