Come a few years, cut of electric spark line is machined (WEDM) , it is all the time undertake on vertical machine tool, if design it,undertake on horizontal WEDM machine tool, will regular meeting makes the person finds everything new and fresh. A model is the horizontal WEDM machine tool of UPJ-2, by Makino company (the Mei Sen that American headquarters is in Ohio) development, exhibit in IMTS2004 first time. It just does not design the exchange of vertical WEDM machine tool with commonly used admiral simply to become horizontal state from total construction. However one kind basically needs to satisfy North America market, the new product that the need that machines nozzle of eject of spare parts of mould of small small-sized gear, fibre optics, ink and medical apparatus and instruments to wait for small small-sized and accurate part to satisfy for example develops. In the design, ask according to the use of these spare partses and study via the analysis, choice horizontal structure may have more advantages, and the WEDM equipment that decides the machine tool the design makes horizontal. Although can undertake horizontal WEDM is the most apparent characteristic of this kind of machine tool, but it can be used small to 0.

The electrode silk of 00078 inches extremely fine diameter undertakes machining, the port with be being had more principal (be located in Mixiegen according to Makino company the product manager John Shanahan of the center of Auburn Hills technology of the city introduces, 0.

5 times) . The machine tool of UPJ-2 horizontal WEDM that Makino company develops. Passing the electrode silk that uses successive movement to wear, the two end of perforative part semifinished product, horizontal is machining outfit clip and immerse the nice spare parts in working fluid. But, use so fine electrode silk to undertake WEDM, to the machine tool stylist basically will face the challenge that comes from two respects: 1.

In using so fine electrode silk to undertake WEDM, reliable wearing silk automatically will be the first difficult problem that must face above all. Study through experimenting for many times, the ultimate solution that find out is, design the system wearing silk of a structure tubal account, execute wear silk automatically. It is through using, negative air pressure, pull, push a diameter for 0.

00078 inches electrode silk, cross a diameter for 0.

0019 inches spare parts leaves filar hole. Use negative air pressure mostly normally namely vacuum attraction, cross electrode silk the aperture that bring silk automatically from the V of the orifice that bring silk cone. Of course in use, the dependability of the aperture bringing silk that it does not have V cone than orifice wants tall. 2.

The 2nd difficult problem that will face is, raise electrode silk uphold power. The machine tool designed can one constant gravity goes to automatism the electrode silk on electrode silk promotes a system. Uphold power enoughly in order to make sure the electrode silk in WEDM is had. Introduce according to Mr Shanahan, carry research, the above solution that conception gives did not make machine tool structure becomes very complex, but the operation rises to still go to the lavatory easily with vertical machine tool. Use fine electrode silk, use horizontal the principal port of deferent plan depends on, it can undertake to nice small-sized spare parts precision is machined exceeding (it is quite important that this one advantage controls valve spare parts to machine with servo to similar aviation, it can make grow square model the circular arc radius of the aperture that connect oil is machined very smally, the control precision that raises servo orgnaization greatly) . Deferent plan still needs electrode silk horizontal to design C axis the machine tool headstock that installs to become perpendicular position with vertical machine tool inside, when treatment, hold the part clip to be located in in on the standard clamping apparatus on Erowa tray, undertake assembling and unassemble automatically to the spare parts by the robot. Tooth form of graphic representation sprocket is use diameter namely for 0.

00078 inches electrode silk WEDM and into. What the whirligig of the C axis of such design still can move with X, Y is harmonious cooperate, have complex accent to the spare parts such as of intricate geometry appearance model the mould undertake machining, it is the another main characteristic that place of horizontal WEDM machine tool has. Not only such, horizontal WEDM still can make drossy the processing with contact (these processing are normally most the business that allows handlers to headache) it is easy to become very simple. What design for the machine tool is drossy handle installation with contact, can automatic in treatment will drossy processing is mixed completely the dinky contact that keeps easy processing only, solved the drossy accumulation of long-standing move, the technical difficult problem that affected line cut speed badly to rise and decreased to need to have the auxiliary time such as cut 2 times to contact with contact greatly, also avoided the loss that causes possibly to the spare parts at the same time. Together with, very fine electrode silk has the capacity of fast transmission electric current, and it is to the cut speed of the spare parts with electric current transmission speed becomes direct ratio, so relatively the WEDM rate that the earth raised a machine tool, still can undertake inside bigger range automation is produced, improve manufacturing efficiency. Machine tool lathe bed is measured with most coordinate opportunity is same, make by granite material, have very strong fight brace up ability and the effect that reduce high temperature to arise to the spare parts. The machine tool must be installed commonly in constant temperature atelier, the difference in temperature in assuring to machine is in less than of 1 ° F.
