摘要： PURPOSE:To extent a maintenance period of a filter and to reduce a maintenace expense of the same, by removing iron filings off from a contaminated liquid generated from a work or an electrode prior to filtering of the contaminated liquid by the filter. CONSTITUTION:An electromagnet 7 is provided in a contaminated liquid tank 1. The electromagnet 7 is magnetized and the magnetic field is made to generate by electrifying the electromagnet 7. Iron filings generated through a work is adsorbed from within a contaminated liquid in the contaminated liquid tank 1 by the generated magnetic field. With this construction, half of particulates in the contaminated liquid in the contaminated liquid tank 1 is removed. As the iron filings in the contaminated liquid is removed like this, the particulates in the contaminated liquid tank 1 become only copper filings and a number of the particulates becomes the half. Then, meshes of a filter 5 is hard to be clogged as a number of the particulates is reduced when the contaminated liquid is filtered by the filter 5 due to a matter that the contaminated liquid, whose particulates have become the half, is sent to a filter tank 2 for the contaminated liquid by a feed contaminated liquid pump 3.
摘要翻译：目的：为了延长过滤器的维护时间并减少维护费用，通过在过滤污染液体之前从工作或电极产生的污染液体中除去铁屑。构成：电磁体7设置在污染的液体罐1中。电磁体7被磁化，并且通过使电磁体7通电而产生磁场。通过工作产生的铁屑从污染液体中的污染液体中被吸收罐1由产生的磁场。利用这种结构，污染的液体罐1中被污染的液体中的一半的微粒被去除。由于被污染的液体中的铁屑像这样被去除，污染的液体罐1中的微粒仅成为铜屑，并且许多颗粒成为一半。然后，当污染的液体被过滤器5过滤时，由于微粒已经成为一半的污染液体被送往一个过滤器5，因此随着许多颗粒物的减少，过滤器5的网孔难以堵塞用于污染液体的过滤罐2由饲料污染液体泵3。

摘要： PURPOSE:To shift a work tank door so easily and little in floor space by man power, making the work tank door attachable and vice versa to and from a tank body as well as making it so as to be slingingly supported by the lifting mechanism installed in the body. CONSTITUTION:A work tank door 2 is clamped to a work tank body 1 by what a clamper 4 is made to come into a state of being clamped, and completely separated from the work tank body 1 by making the calmper come into a state of being unclamped. Next, the work tank door 2 separated from the work tank body 1 is slung by a spring balancer 6 with force of the same degree of its own weight so that it can be easily moved up and down by man power, thus the work tank door 2 is housed in space between supports 7a and 7b by man power. And, the work tank door 2 can be opened or closed only when it is moved almost vertically, and even when a work delivery device is set up in front of the work tank door 2 as well as even when a work conveying rail is set up at the same height position as a lower end of the door 2, it is able to be opened or closed, thus the time required for work delivery is reducible.

摘要： PURPOSE:To prevent machining fluid and sludge or the like from splashing on a rail by providing a machining fluid scatter preventing means in a pallet in its workpiece loading surface or an opposite side thereto, in the case of a device in-out carrying a workpiece for a wire electric discharge machine. CONSTITUTION:Between upper and lower part wire guides 5 and 7, a wire electrode 8 is linked machining a workpiece 24 by applying voltage to the wire electrode 8 while supplying machining fluid to upper and lower part nozzles 10 and 11. At this time, machining fluid 10a from the upper and lower part nozzles 10 and 11 is scattered hitting the workpiece 24 in its upper and lower surfaces. The scattered machining fluid 10a hits upper and lower part machining fluid scatter preventing covers 51 and 53 to scatter no more. The workpiece 24 is completed in its machining and mounted to a pallet 23 removed in its retaining plate and moved to a workpiece exchanger after a cross table 2 is moved to an exchange position of the pallet 23.

摘要： PURPOSE:To make it possible to remove a core from a machined portion of a work with magnetic attraction by exerting a magnetic force of an electromagnet disposed on a holder of a core handling device through freely deformable iron powder contained in a lapping film. CONSTITUTION:A core 2 is cut with a wire electrode off a work 1. An upper nozzle 4 is moved upward to avoid interference with an electromagnet 11. A holder 12 driven with a drive device moves above the core 2 and moves downward. When the core 2 drops from the cutoff position, a lapping film 13 containing iron powder 14 comes in contact with the work 1 and maintains a sufficient area of contact with the core 2. When the iron powder is magnetized by magnetizing the electromagnet 11, the work 1 and the core 2 are also magnetized. When the holder 12 moves upward, the core 2 moves upward while being attracted to and together with the electromagnet 11 and is removed from a machined portion of the work 1.

CONSTITUTION:In the case of using a processing liquid having a specific resistance of 10 KOMEGA.cm approximately, the spacing between electrodes 6 is set to approx. 1mm, and a voltage of 100 V is impressed to cause flowing of a current of approx. 0.1 A, and now it is possible to sense that the processing liquid surface 2a has attained a set level. The electrodes consist of a rod-shaped electric conductor having rigidity, and their bottoms 6a shall be situated at a certain intended level and thus installed vertically at the inner wall of a processing trough 1. The electrode tops 6b are situated apart from the processing liquid surface 2a, and there is no risk of electric errosion between the processing liquid 2 and the electric wire for signaling 8 connected in this position, and further the sensing part is fixed type, and the wire 8 is not necessarily made of thin and soft material to ensure that it is selected from a wide range of selection.

摘要： PURPOSE:To treat plural pieces of works simultaneously at a quick rate by means of electro-discharge machining, by controlling plural electrodes individually and optionally, and keeping a discharging state at every electrode head in optimum conditions. CONSTITUTION:Works 3a and 3b are set to the inside of a work tank 2, and electrodes 7a and 7b are attached to surface plates 16a and 16b to be lifted by heads 13a and 13b. Each electrode is connected to power sources 9a and 9b and controllers 15a and 15b. Each control signal out of these controllers 15a and 15b is transmitted to these heads 13a and 13b whereby each electrode approaches the work till respective spark gaps get discharging, and afterward the spark gap is not affected by a discharging state of the other spark gap, thus each individual one can keep its optimum discharging condition.

摘要： PURPOSE:To prevent a lower nozzle from damage caused by a core after being cut off, by applying magnetic force to the machined surface of a work from a magnetic force generating means, holding the core being cut off from the work, and removing it by a removal means. CONSTITUTION:An electric magnet 10 fixed to a work 1 placed on surface reference boards 2a, 2b generates a magnetic force at any desired timing to give the work 1 a force to attract a core 6 before being cut off, and when a wire electrode 3 severs the core 6 completely, it is attracted to the processed surface on the electric magnet 10 side. After an upper nozzle 5 has moved in Z, X, or Y direction, a magnet 7 fitted in a holder 8 of a core removal means 20 is moved to over the core 6 by an arm 9 to come in contact with the oversurface of the core 6. At the same time, the electric magnet 10 is demagnetized, and the core 6 is attracted by the magnet 7 for removal out of the processing part of the work 1. This prevents the core after being severed from damaging the lower nozzle.

摘要： PURPOSE:To make it possible to extend and retract a loading arm by using machining liquid jetted from a nozzle at a high speed in a film-like condition as a fluid shutter so as to inhibit the machining liquid in a machining tank from flowing out through a window part even though machining liquid is fed in the machining tank to a height greater than the height of a side face opening. CONSTITUTION:A fluid shutter creating nozzle 13 which is curved arcuatedly, is disposed in the upper edge section of a window part 20 in a machining tank 11, and jets machining liquid fed from a hose 14 along the window section 20 downward at a high speed so as to form a film-like shutter. Even though the machining liquid 10 is fed up to a level higher than the height of the window part 20, it is possible to restrain the flow-out of the machining liquid from the window to a slight amount. A loading arm 15 which has an external shape of a round rod so as to prevent the flow of the fluid shutter from being inhibited and which holds a workpiece, enters into the machining tank 10 through the window part 20 so as to set the workpiece. Thus, it is possible to introduce the workpiece into and from the machining tank 11 which are filled with the machining liquid, thereby it is possible to efficiently machine several workpieces one by one.
