Abstract
A work tank ( ) for an electric discharge machine includes a tank wall ( ) having an opening in a front surface and surrounding a workpiece; a front door ( ) horizontally movable between an unlock position, where the front door is vertically movable, and a lock position, where the opening is closed in a generally liquid-tight relationship; a pair of brackets ( ) attached to both sides of the front door and extending rearwardly; a handle lever ( ) capable of pivoting about a fulcrum ( ) and supported on at least one of the brackets; and a cam follower, fixed to the handle lever further forward than the pivot, the cam follower being vertically movable between a first position (H ) higher than the fulcrum and a second position (H ) lower than the fulcrum. The cam follower is fitted loosely into a groove ( ) extending vertically and formed in a rail block ( ). Horizontal movement of the cam follower is restricted. When the cam follower is at the first position, the front door is in the unlock position and is vertically movable. When the cam follower is at the second position, the front door is in the lock position and is held closed within the opening in a generally liquid-tight relationship.
