ABSTRACT:
An eye mold device for electrical machining device in which the electrode with different outer diameter can be readily and firmly supported within the eye mold for machining. A substantially triangular passage is defined by three accurate rods which are disposed within a mounting groove of a receiving barrel. When the electrode is inserted within the triangular passage, the electrode can be vertically and firmly supported and calibrated therein. By this arrangement, the electrode can be prevented from skewing during the machining process. On the other hand, the circularity and verticality of the performed hole can be kept. The size of the triangular passage is defined and dependent upon the outer diameter of the three accurate rods. In practice, the three accurate rods are selected and based on the outer diameter of the electrode such that the triangular passage formed thereof is matched to the outer diameter of the electrode. Those three accurate rods are suitable disposed within the mounting groove of the receiving barrel. The size of the triangular passage can be readily adjusted by selecting different accurate rods. As a result, different size of electrode can be readily supported by the triangular passage for a machining work. An accurate machining work can be therefore done.
