摘要:
A heterogeneous composite consisting of near-nano ceramic clusters dispersed within a ductile matrix. The composite is formed through the high temperature compaction of a starting powder consisting of a core of ceramic nanoparticles held together with metallic binder. This core is clad with a ductile metal such that when the final powder is consolidated, the ductile metal forms a tough, near-zero contiguity matrix. The material is consolidated using any means that will maintain its heterogeneous structure.

摘要:
In an electrical discharge machine, the top end of a vertically extending electrode is supported by an electrode holder so as to be able to be raised and lowered, the circumferential surface of the bottom end of said electrode is supported by an electrode guide that is disposed so as to be able to move vertically with respect to the electrode holder, and the position of said electrode guide is detected by a position detection unit. This electrical discharge machine is provided with a work-tank raising/lowering device. During electrical discharge machining, said work-tank raising/lowering device raises/lowers a work tank, in accordance with the electrode-guide position (Hg) detected by the position detection unit, so as to set the distance from a prescribed part of the work tank to the electrode-guide position (Hg) equal to a prescribed value (Ha).

摘要:
The invention relates to a method for electrical discharge machining of electrically non-conductive material in which a layer of an electrically conductive substance is applied as an auxiliary electrode on the electrically non-conductive material. Said method is characterized in that the electrically conductive substance is chemically converted by oxidative heat treatment after electrical discharge machining.

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.
