    With the continuous development of industrial automation, wire cutting gradually replaces the old-fashioned traditional cutting method, which is widely used with its unique characteristics. One. The principle of wire cutting Free positive ions and electrons accumulate in the field, which soon forms a conductive channel that is ionized.

    At this stage, an electric current is formed between the two plates. As a result, numerous collisions between the particles form a plasma region, which quickly rises to a high temperature of 8,000 to 12,000 degrees, instantly melting the material to be processed on the surface of the two conductors, and at the same time, due to the vaporization of the electrode and the dielectric liquid, a bubble is formed, and its pressure rises regularly until it is very high. Then the current is interrupted and the temperature drops suddenly, causing the bubbles to turn inward**, and the resulting momentum throws the melted material out of the crater, where it is then rotted....

    The wire cutting machine is mainly composed of three parts: machine tool, CNC system and high-frequency power supply. The numerical control system is composed of single-chip microcomputer, keyboard, and frequency conversion detection system, and has the main functions of gap compensation, linear interpolation, arc interpolation, and automatic processing of broken wires. It can cut materials, such as high-strength, high-toughness, high-hardness, high-brittleness, magnetic materials, as well as precision and fine-shaped parts.

    Wire cutting technology and wire cutting machine tools are being widely used in all walks of life.

    The machine tool is composed of a bed, a wire storage mechanism, a wire frame, an XY workbench, an oil tank and other components. The molybdenum wire wound on the wire storage cylinder is reciprocated at high speed through the wire frame. The workpiece is fixed on the XY table.

    The movement in the X and Y directions is each controlled by a stepper motor. Every time the numerical control system sends out a signal, the stepper motor takes a step, and drives the lead screw in both directions to rotate through the intermediate transmission mechanism, so that the X and Y workbenches are fed respectively.

    Cutting machines are distinguished from the cutting materials, and are divided into metal material cutting machines and non-metallic material cutting machines.

    Metal material cutting machines are divided into flame cutting machines, plasma cutting machines, laser cutting machines, waterjet cutting machines, etc.;

    Non-metallic material cutting machines are mainly knife cutting machines.

    The cutting machine is distinguished from the control mode, which is divided into CNC cutting machine and manual cutting machine.

    CNC cutting machine is to use a digital program to drive the movement of the machine tool, and when the machine tool moves, the cutting tool is randomly equipped to cut the object. This kind of mechatronics cutting machine is called CNC cutting machine.

    The laser cutting machine is the fastest efficiency, the highest cutting accuracy, and the cutting thickness is generally smaller. The plasma cutting machine also has a fast cutting speed, and the cutting surface has a certain slope. Flame cutting machines are designed for use with thicker carbon steel materials.

    There are currently three types of cutting technologies: blade cutting, laser cutting, and plasma cutting.

    Blade dicing refers to the cutting of wafers with diamond blades, which is the most common, but is prone to frictional heat and debris, and requires pure water and cooling and cleaning during the cutting process.

    Laser cutting is more accurate, making it easy to process wafers with thin thickness or with very small spacing between dicing lines.

    Plasma cutting uses the principle of plasma etching, so this technique can be applied even if the scribing line spacing is very small.

    (1) When the CNC wire cutting machine tool is processing, a DC pulse voltage of 20kHz and 150V is added between the cutting tool (copper wire or molybdenum wire) and the workpiece. Pulse discharge between the electrode wire and the workpiece. When the distance between the tool and the workpiece is close enough (approximately, the voltage breaks down to cool the cutting fluid medium, and the cutting tool and the workpiece are evenly discharged on the full length of the close proximity, and the temperature of the high energy density EDM discharge can reach 7000 or higher, and the high temperature makes the metal to be cut vaporize instantaneously, generating metal oxides, which melt in the cutting fluid and are taken out of the processing area by the moving cutting tool.

    2) The electrode wire moves along its axial direction (vertical or z-direction).

    3) The basic physical principle of the numerical control movement of the workpiece relative to the electrode wire in the x and y planes is that free positive ions and electrons accumulate in the field, and soon form a conductive channel that is ionized. At this stage, an electric current is formed between the two plates. As a result, numerous collisions between the particles form a plasma region, which soon rises to a high temperature of 8,000 to 12,000 degrees, instantly melting some material on the surface of the two conductors, and at the same time, due to the vaporization of the electrode and the dielectric liquid, a bubble is formed, and its pressure rises regularly until it is very high.

    Then the current is interrupted and the temperature drops suddenly, causing the bubbles to turn inward**, and the resulting power throws the melted material out of the crater, and then the corroded material re-condenses into small spheres in the dielectric solution and is discharged by the dielectric solution. Then, through the monitoring and control of NC control, the servo mechanism executes to make this discharge phenomenon uniform, so that the workpiece is processed, so that it becomes a product that meets the required size and shape accuracy.

    The basic working principle of wire cutting is to use a continuously moving thin metal wire (called wire cutting electrode wire) as an electrode to carry out pulse spark discharge on the workpiece to abrode the metal and cut the workpiece. Wire cutting is mainly used to process a variety of complex shapes and precision and fine workpieces, for example, wire cutting can process punches, dies, convex and convex dies, fixed plates, strippers, etc., forming tools, templates, wire cutting can also process a variety of micro holes, narrow slots, arbitrary curves, etc. Wire EDM has many incomparable advantages, such as:

    Wire cutting has the outstanding advantages of small machining allowance, high processing accuracy, short production cycle, low manufacturing cost, etc., and wire cutting has been widely used in production. For wire-EDM to operate normally, the following conditions must be met:

    1. A certain gap must be maintained between the molybdenum wire and the surface to be processed of the workpiece, and the width of the gap is determined by the processing conditions such as working voltage and processing volume.

    2. When EDM wire cutting machine tool processing, it must be carried out in a liquid medium with certain insulation properties, such as kerosene, saponified oil, deionized water, etc., and the high insulation is required to facilitate the production of pulsed spark discharge, and the liquid medium also has the effect of eliminating electroerosion products and cooling electrodes in the gap. Keep a certain gap between the molybdenum wire and the surface of the workpiece to be processed, if the gap is too large, the voltage between the poles can not penetrate the interpolar medium, and the electric spark discharge can not be generated; If the gap is too small, it is easy to form a short-circuit connection and cannot produce an electrical spark discharge.

    3. Pulse power supply must be used, that is, the spark discharge must be pulsed and intermittent. In the interval between the pulses, the gap medium is ionized so that the next pulse can be discharged between the poles.
