Characteristics of DK7735 wire cutting machine

1. Machining based on the principle of electric erosion, the electrode wire does not directly contact the workpiece, and the force between them is very small, so the deformation of the workpiece is very small, and the electrode wire and fixture do not need too high strength.

2. The linear electrode wire is directly used as the electrode, and there is no need to make a special electrical grade, which can save the cost of electrode design and manufacturing.

3. It can process workpieces with complex shapes that are difficult or impossible to process by traditional cutting methods. Because the NC WEDM machine tool is a digital control system, it only needs to compile different control programs to process different workpieces, and it is easy to realize automatic machining for workpieces of different shapes. It is very suitable for the processing of small batch parts, single parts and trial products with complex shape, and the processing cycle is short.

4. Four axis linkage is adopted to process taper, upper and lower special-shaped bodies and other parts.

5. In the traditional turning, milling and drilling, the hardness of the tool must be greater than that of the workpiece, while the electrode wire of the NC EDM machine tool does not have to be harder than the workpiece material, and can process materials with high hardness or brittleness, which are difficult or impossible to process by the general cutting method. In machining, the electrode wire as a tool does not need grinding, which can save auxiliary time and tool cost.

Advantages of DK7735 wire cutting machine

1. NC wire cutting is a contour cutting process, which does not need to design and manufacture forming tool electrodes, which greatly reduces the processing cost and shortens the production cycle.

2. Direct use of electric energy for pulse discharge machining, tool electrode and workpiece are not in direct contact, and there is no macro cutting force in machining. It is suitable for machining low stiffness parts and small parts.

3. No matter how hard the workpiece is, as long as it is conductive or semi-conductive material, it can be processed.

4. The cutting seam can be as narrow as 0.005mm, and only the workpiece material is processed along the contour. The material utilization rate is high, which can effectively save valuable materials.

5. The moving long electrode wire continuously passes through the cutting area, the loss per unit length of electrode wire is small, and the machining precision is high.

6. Generally, water-based working fluid is used, which can avoid fire, is safe and reliable, and can realize unattended continuous processing day and night.

7. It is usually used to process straight wall surfaces on parts. Through x-y-u-v four-axis linkage control, it can also carry out taper cutting and process parts such as special-shaped bodies of upper and lower sections, curved bodies with distorted shapes and spherical bodies.
