BAOMA DK7780D WIRE EDM MACHINES

Technical Description

The BAOMA DK7780D Wire EDM Machine is a high-precision CNC-controlled electrical discharge machining system designed for accurate and efficient metal cutting. Featuring an X-axis travel of 31.5 inches (800 mm) and a Y-axis travel of 39.4 inches (1000 mm), this machine provides a large working area suitable for a wide range of industrial applications. The CNC control system ensures precise and automated operation, enabling complex cutting patterns and consistent repeatability. The machine is equipped with a robust worktable capable of handling heavy loads up to 3000 kg, making it ideal for processing large and thick workpieces. It supports a maximum workpiece thickness of 300 mm and can achieve a maximum cutting speed of 150 mm²/min, ensuring high productivity. The DK7780D utilizes a molybdenum wire electrode with a diameter range of 0.15–0.2 mm, which travels at speeds between 5–11 m/min, allowing for fine and accurate cuts. The machine delivers excellent surface finish, with roughness values as low as 1.5 μm after three cutting passes. Its precision is further enhanced by high-quality linear guides and ball screws, resulting in an accuracy of ≤0.012 mm for octagon cutting and ≤0.04 mm for taper cutting. The DK7780D also features an adjustable wire guide frame, central lubrication system, and a working solution reservoir with a capacity of 100 liters. With a maximum working current of 8 A and a power consumption of 3 KVA, the machine operates efficiently on a 380V/50Hz power supply. The controller type is BMW-3000, providing reliable and user-friendly operation. This machine is well-suited for industries requiring high-precision metal cutting, including mold making, tooling, and precision engineering.
