Mitsubishi Electric adds banner with more than 1m wire-cut EDM

In the "DIAX BA" series of wire-cut EDM machines for component machining, Mitsubishi Electric has added a model "DIAX BA24" that can process medium and large workpieces with a banner of 1050 mm. Expanded the processing range of "BA8", which was launched in November 2006, and can process large-scale aerospace related components and tools. The width, length and height of the machinable workpiece are 1050mm, 820mm, and 305mm, which are about 1.5 times that of the BA8. The allowable weight has also reached 1500kg which is three times the original.

As the workpieces tend to increase in size, the company has developed a power supply unit "V350II power supply" in order to improve production efficiency and reduce operating costs when machining difficult materials. With the voltage control technology of V350II, high-speed machining of hard-to-cut materials such as polycrystalline diamond (PCD) and cubic boron nitride (cBN) and nickel superalloys is realized. PCD and cBN are prone to chipping, but the V350II "power control for blank processing" function can suppress cracks and defects in corners and the like. Further, the lead electrode and the graphite electrode for the scribing electric discharge machine which is further fine and thin can also prevent the curl and the defect.

In addition, the vertical precision of the finished surface is improved by the fine pulse control of the V350II. Even in the state of reducing the wire speed of the wire, high vertical accuracy is ensured. The WEDM consumption per unit of processing time can be reduced by up to 40% compared to the “FA Advance” series, resulting in lower operating costs.

In addition, the machining slot door is also sliding so that the workpiece can be easily removed. The movement amount of the X/Y/Z axis is 600 × 400 × 310 mm. Compared with the mid-line wire EDM "FA20S Advance", the X-axis is expanded by 20% and the Y-axis is expanded by 14%. This reduces the number of preparations for large-scale work.
