6 The structure Water cooling on the lower arm prevents thermal expansion caused by heat buildup within discharged cables. Therefore, the accuracy will be improved. Rigid U,V truss design. Stainless steel work table with hardness HRC50. High response AC servo motor for guaranteed accuracy. Extra wide machine base. To ensure thermal balance throughout the ribs allocation of a casting-iron of 5-axis, the machine body is designed by Finite Element Analysis (FEA) assuring optimized mechanical structure, the reliability of rigidity is very high. Electric Lubricator Laser calibration, pitch error compensation. To achieve the desired precision, an extended distance between linear guide ways and a cryogenic treatment C1 class ball screws with supports of two sides and a high resolution AC servomotor are employed. These outstanding features boost accuracy of micro step motion up to 1 μmm. Rugged cast iron is the foundation stone of precision. Close loop linear scale (Option). V650 X-axis positioning accuracy (By Laser measurement system) 5

7 The generator Stable Open Voltage Circuit Adopt chopper switch power and a voltage regular can be obtained. Small value of ripple with steady voltage output. The desired efficiency can be expected. Optional 20 steps to ignite voltage to fit sophisticated machining. A steady sparking circuit with same gap between ignitions can be obtained to reach precision machining. High Frequency Calculating and Pulse Control Use the embedded system to reduce the loading of the control. Use RS-485 networks to transmit between the module groups. Use CRC to verify if all data is received correctly. Adapts ASIC chip to increase the stability of the circuit. Watch Dog functions for self-protection. Sparking relevant information real-time feedback and it makes spark erosion steady. DC discharge EF (non-electrolytic) discharge EF (AC) Electrolysis Free Generator System EF (AC) Electrolysis Free Generator System is a new design which provides cutting performance improved and it hastens the original circuit by 10%. Up Guide Low Guide The short circuit occurs due to the start hole position error or even the hole is at an angle. Use the special short-cut circuit to obviate the short area. Modular-designed system An optimal module on the electric circuit PCB, each module I/O give a LED indication, benefits after sales service and provides more speedy maintenance. Short-circuit obviate solutions Usual occurrence of short-circuit after threading due to misalignment (mistake) of positioning at drilling point (common occurrence especially in machining thick workpiece ), using special electric-discharge circuit, getting rid of shortcircuit by electric-discharging, increasing the machining efficiency, minimizing waste of working time due to short-circuit. RTS (Real Time Sparking) Adopt 16 pieces of MOSFET to effective sparking erosion. To an upper error at 10ns by means of symmetry of MOSFET allocation and synchronization of signal control. Reinforce PCB Insulation and enhance the big current. Effective discharging Ineffective discharging Chips 6

8 The Auto Wire Threading A continual unmanned operation day and night Reliable of Auto Wire Threading System from EXCETEK EXCETEK AWT has a very successful threading rate, and provides a continual unmanned operation day and night. Its outstanding feature which compares to other competitors is threading at the point of wire breakage. Water Jet Function enables the machine to thread a piece of thickness at 500 mm. Invent a device to deal with the waste Chopped Wire. 7 Note1: (We suggest over 120mm high work piece on air use water jet function for Auto wire threading)

9 Start point Uncut hole record Start and break point information Threading point Threading at break point AWT Monitor AWT Result Monitor Annealing wire threading Threading at wire break point : Using annealing to improve the straightness of wire. The wire can be threaded at the break point during machining, with virtually 100% reliability, without the need to return to the start hole. Submerged wire connection : Wire threading is also easily executed during submerged machining. No need to drain and refill the work tank. Multi-hole machining function: In a rare event when the machine fails to rethread at a hole during multiholes machining, the system will skip to the next hole. The information of the skipped hole is automatically stored in memory and can be recalled later to complete the cut. Threading with water jet : In the case of high work piece, water jet can be use to enhances the wire threading. 8

Ground connection: The wire cut EDM must always be grounded to prevent external noise and prevent radio disturbance, and prevent earth leakage. Class C grounding (grounding resistance 10 Ω or less) as set forth in the Electric Facility Standards is recommended for the EDM. (Fig. 1) Common grounding can be used if noise from other device will not enter through the common grounding; the grounding cable must be connected independently to the grounding location, and use a 14mm 2 grounding wire. (Fig. 2) 5. Shield room: Install a shield room if the wire-cut EDM affects television or other communication device in the area, observe the following points when installing the wire cut EDM in the shield room and grounding the Wire cut EDM in the shield room is necessary.
