摘要： AT (automatic threading) of wire through a workpiece without the need for a preformed through-hole therein is achieved on a TW (traveling-wire) electroerosion machine (TW-E machine) by utilizing a tubular electroerosion electrode positioned in axial alignment with a wire-threading path. Wire from a wire supply is introduced into the tubular electrode so as to extend through a tool holder therefor. The tubular electrode is advanced along the wire-threading path into and through the workpiece while electroerosively forming a bore therein. Wire is dispensed from the supply to allow wire to move out of the tubular electrode while the latter at least partially remains in the bore so that the wire passes into the wire outlet side of the cutting zone towards a takeup assembly. The tubular electrode may then be retracted along the wire-threading path from the workpiece while leaving wire in the bore finished in the workpiece.

摘要： A press having a machine frame section (10) and a movable section capable of reciprocal movement in a vertical direction relative to the machine frame section, for making products using a pair of dies. The movable section includes a slide (24) to which one of the pair of dies is mounted, and a horizontal guide surface is formed on one of the machine frame section and the movable section. A drive slider (51, 52, 53, 54) has a horizontal sliding surface facing the horizontal guide surface and an inclined sliding surface inclined at a specified angle, and is movably joined to the one of the two sections. A swash plate (51, 52, 53, 54) has an inclined guide surface facing the inclined sliding surface, and is fixed to the other of the two sections. A linear motor (1a, 1b, 2a, 2b, 3a, 3b, 4a, 4b) causes the drive slider to reciplocate along the inclined guide surface of the swash plate through a larger stroke. Energy of the reciprocating drive slider causes the slide to vertically reciplocate through a smaller stroke with a larger pressure.

摘要： A traveling-wire electroerosion apparatus using a first nozzle disposed at one side of a workpiece so as to coaxially surround the electrode wire moving into the workpiece for directing under a relatively low pressure a cutting liquid medium into a cutting zone in the workpiece and a second nozzle disposed at the other side of the workpiece so as to coaxially surround the electrode wire moving from the workpiece for directing under a relatively high pressure the cutting liquid medium into the cutting zone. A liquid flow guidance member, generally in the form of an annular disk or discus, is disposed at that one side of the workpiece and adjacent thereto so as to overlie at least a region of the cutting slot generated behind the advancing electrode wire, which region is adjacent the nozzle opening of the first nozzle. The flow guidance member has a liquid escape passage formed therein adjacent the said nozzle opening and a flow deflecting surface overlying the said region for impeding direct flow of the flushing liquid medium from the cutting slot and creating a high-velocity stream of the high-pressure cutting liquid medium from the second nozzle flowing through and out of that liquid escape passage.

摘要： An electrical machining system utilizing a machining liquid consisting at least in a major part of an aqueous solution containing a deionized water and a surface active agent dissolved therein, the latter having a temperature-dependent solubility in the solution and a cloud point, i.e. a temperature below which it remains dissolved therein. The machining liquid is supplied into a machining zone which produces a liquid effluent in which machining products are entrapped. The liquid effluent is fed to a separation zone where it is heated at a temperature above its cloud point to separate out an amount of the surface active agent and to collect that amount substantially in a solid form while forming a liquid output constituted by a remainder of the liquid effluent. The surface active agent is collected by deposition on a carrier material, e.g. iron particles. When iron particles are used, an electromagnet may be employed to decrease the time necessary to recover the surface active agent. The carrier material having the deposit of the surface active agent may be brought into contact with a cool deionized water to form a solution of the collected surface active agent therein.
