摘要:
An improved dual fabrication liquid circulatory system for an electric discharge fabrication machine, having an oily-water separation system of single, dual, or triple-tank types. The single-tank oily-water separation system utilizes a water level sensor to control the switch of an electric magnetic valve and the discharge of oily-water fabrication liquid from an oil discharge pipe and a water discharge pipe. The dual-tank oily-water separation system directs fabrication liquid into a filtration tank such that fabrication liquid enters a water storage tank through a water discharge pipe and the floating oil flows into an oil storage tank from an oil discharge pipe. The triple-tank oily-water separation system includes a water filtration tank and an oil filtration tank with the water filtration tank divided into two tanks by a separation board. The floating oil in the upper oil layer enters an oil filtration tank through a flow pipe and enters the oil storage tank through an oil discharge pipe.

Machining methods for machine tools where a workpiece can be manually moved by an operator or by automatic operation. A drawing file is displayed on a screen and machining is performed. An evaluation is performed to determine if the processed points of the workpiece match the desired processing coordinates within a tolerance range. Accordingly, the system is selectively activated to prevent processing at incorrect processing points or deviating from the tolerance range of the desired processing points. Processing yield rate is improved and all processing points are monitored by the system and displayed on a drawing file screen.

A combination drilling/tapping electro-discharge machining (EDM) drill capable of selectively operating in hole drilling mode or thread tapping mode is provided. The EDM drill includes a rotation axis as a R axis driven by a servo motor; a machining axis as a Z axis driven by another servo motor being capable of switching between a default mode and a servo following mode for realizing a spark following; and a thread electrode extended down from the R axis through a guide; wherein a dielectric supply and said R axis rotates for performing said EDM thread tapping on a work piece.

A circulation system is capable of dual functions of providing an electrode discharge machine with water or oil to serve as a finishing fluid for the process of drilling fine holes in a work piece of an aluminiumn, steel, or tungsten steel material. The circulation system comprises an oil-water separating tank, a water filtration tank, an oil filtration tank, a water purifying device, and a control computer. The water purifying device is connected in parallel with a discharge conduit from the water filtration tank for recirculating flow to the oil-water separating tank.

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.
