EDM machines are commonly used metal processing equipment. Due to their high precision and high efficiency, they are widely used in mold manufacturing, aerospace, automobile manufacturing, electronic manufacturing, and other fields. However, the operation of EDM machines requires certain skills and experience, otherwise, safety accidents and processing quality problems are prone to occur. This article will introduce the operation guide of EDM machines to help you use EDM machines correctly and improve processing efficiency and quality.

1. Adjust processing parameters

Before processing, the processing parameters need to be adjusted according to the processing materials and processing requirements. Mainly including voltage, current, pulse width, pulse frequency, and other parameters. In general, the voltage and current should be appropriately increased to increase the discharge energy; the pulse width and pulse frequency should be appropriately reduced to improve processing accuracy and stability.

2. Install the electrode and workpiece

When installing the electrode and the workpiece, it is necessary to ensure the distance and positional relationship between the electrode and the workpiece. Generally, the distance between the electrode and the workpiece should be kept between 0.1-0.3mm to ensure the stability of the discharge channel and the processing effect. At the same time, it is necessary to ensure the positional relationship between the electrode and the workpiece to avoid processing deviations and errors.

3. Start EDM machines

Before starting the EDM machines, you need to check whether the parameters and equipment of the EDM machines are normal. Once an abnormality is discovered, it needs to be shut down for maintenance in time to avoid safety accidents and processing quality problems. When starting EDM machines, you need to follow the operating procedures and steps to ensure the correctness and safety of the operation. At the same time, it is necessary to pay attention to the safety protection measures of operators, such as wearing protective glasses, gloves, etc.

4. Monitor the processing process

During the processing process, the processing effect and processing quality need to be continuously monitored. Once processing deviations or errors are discovered, processing parameters and positional relationships need to be adjusted in time to ensure processing effects and processing quality. At the same time, it is necessary to pay attention to safety matters during processing, such as preventing short circuits between electrodes and workpieces and preventing discharge pits from being blocked.

5. Shutdown and maintenance

During shutdown and maintenance, operating procedures and procedures need to be followed. Under normal circumstances, the discharge pits and carbides on the surface of the electrode and workpiece need to be cleaned in time to ensure the processing effect and processing quality. At the same time, it is necessary to regularly check whether the various parameters and equipment of EDM machines are normal, such as electrode wear, voltage fluctuation, etc.

In short, the operation of EDM machines requires certain skills and experience, and the operating procedures and steps need to be strictly followed to ensure the correctness and safety of the operation. At the same time, attention needs to be paid to safety matters and maintenance requirements during processing to extend the service life of EDM machines and improve processing efficiency and quality.
