China's EPS Cutting Machine share of the world's first
  China's EPS Cutting Machine ownership accounted for the world's first, technical level and the gap between the world's advanced level is gradually narrowing. Especially in recent years, the application of computer technology and wire electrode EDM technology to achieve a variety of complex shapes of mold and parts processing automation, the control accuracy of up to 1ILm, the actual processing accuracy of up to 0.01 mm. Surface roughness up to R.1 25 ^ 2 5 iim. EPS Cutting Machine is a precision machining, mold manufacturing essential equipment, it can not only processing the general metal materials, but also direct processing of hardened steel, hard alloy and high hardness metal materials, thus shortening the mold manufacturing and new product development cycle , Has a very good economic benefits. CNC wire cutting machine has the advantages of excellent performance, reliable operation, simple operation, low price, economical and durable, and is widely used in automobile, electronics, instrument, instrument, precision machinery, light industry and other industries, and can be well processed Die (concave and convex, fixed plate) and the pressure model plate, disc cam and a variety of special parts.
EPS Cutting Machine using aluminum wire or hard brass wire as the electrode wire. The workpiece to be cut is the workpiece electrode, the electrode wire is the tool electrode. The pulse power supply sends a continuous high-frequency pulse voltage to the workpiece electrode and the tool electrode (electrode wire). Between the electrode wire and the workpiece with enough, with a certain insulation performance of the working fluid. When the distance between the electrode wire and the workpiece is small to a certain extent, the working fluid medium is punctured, the electrode wire and the workpiece between the formation of instantaneous spark discharge, resulting in instantaneous high temperature, generate a lot of heat, the workpiece surface metal melting or even vaporization ; Coupled with the working fluid medium flushing effect, making the metal was eroded down. This is the EPS Cutting Machine processing principle. The workpiece is placed on the machine coordinate table, according to the numerical control device or the computer program under the control of the predetermined track processing, and finally get the shape of the workpiece. As the barrel to drive the tool electrode, that is, the electrode wire is positive and reverse alternating high-speed movement, so the electrode wire is basically not eroded, you can use a long time.
 EPS Cutting Machine processing process is summed up: the processor according to the drawings of the workpiece size, compiled into a certain program, and through the keyboard or light motor and other input devices to enter the program to the controller. After the control system receives the input program, it is stored in the internal memory. WEDM After receiving the processing command, it starts to run the program and interpolates it through the computer control system. Each operation once, send a feed pulse, and then drive the stepper motor through the amplifier, so that the machine table according to the scheduled track for processing. The system is driven by the wire motor to the storage tube, through the trip switch to make the barrel to do reciprocating motion, EPS Cutting Machine so that the aluminum wire movement. Aluminum wire through the frame on the guide wheel and the workpiece close to a small distance to a certain distance, the emulsion pump that is the working fluid pump cutting machine dedicated emulsion through the nozzle into the work of the incision, high-frequency pulse power generated by continuous high frequency The pulses are applied to the aluminum wire and the workpiece for discharge machining. Stepping motor every step, EPS Cutting Machine making the aluminum wire and the workpiece to produce a discharge processing. According to the gap between the aluminum wire and the workpiece to detect the size of the detection signal into the frequency conversion circuit, and then by the frequency of the frequency generated by the frequency control circuit to control the feed rate. When the gap increases, to speed up the feed rate; when the gap is reduced, it slows the feed rate to maintain a balanced discharge gap, which also maintained a certain processing
