EDM drilling machine--Excellent innovation in precision machining

    In today's modern manufacturing industry, precision machining technology is always at the forefront of the pursuit of higher precision and efficiency. As a revolutionary processing equipment, the EDM drilling machine stands out in various precision machining applications with its unparalleled performance and demonstrates extraordinary strength. This advanced machine can not only make tiny and precise holes in conductive materials, but also perform well on hard-to-process materials such as super-hard steel, carbide, copper, and aluminum. Its unique working principle is to use pulsed spark discharge to erode metal through the vertical up and down movement of the electrode tube, thereby realizing the precision process of punching. It has become the well-deserved choice in the field of precision machining.

    1. The main components and working principle of EDM drilling machine

    The main components of the EDM drilling machine include: electrode brass/copper tubes , jet systems, CNC systems, etc. Among them, the electrode tubes, as the core component, adopts a hollow structure made of thin metal copper tubes, through which the working fluid passes, playing a key cooling and chip removal role. During the processing, the electrode tube and the workpiece generate high temperature through discharge, corroding the metal and eventually forming the required hole. This process is not only suitable for vertical holes, but also for processing small holes with tapers, which greatly expands its application range and enables it to perform excellent performance in a variety of processing scenarios.

    2. Application fields of EDM drilling machine

    In the vast field of precision mold processing, EDM drilling machines are widely used. They are often used as supporting equipment for EDM wire cutting machines to process wire holes, chemical fiber spinnerets, spinneret holes, filter plates, sieve plate group holes, etc. For example, in the manufacturing process of engine blades, EDM drilling machines can efficiently process heat dissipation holes and significantly improve engine performance. In the production of hydraulic and pneumatic valve bodies, it can accurately process oil and gas holes to ensure the normal operation of the valve body and provide reliable protection for various mechanical equipment.

    3. The operation process of EDM drilling machine

    When operating an EDM drilling machine, the purpose and function of each component are crucial. The emergency stop button can immediately shut down the machine power in an emergency to ensure the safety of the operator; the start button is used to start the machine and provide initial power for the operation of the equipment; the processing knob controls the input and output of the processing power, and flexibly adjusts the processing status; the rotating head operation knob is used to control the rotation of the electrode tube to ensure the precise processing angle; the manual spindle up/down operation switch accurately controls the up and down movement of the spindle to meet different processing requirements. In addition, there are spindle lock switch, gap stability adjustment switch, pulse parameter adjustment code disk and spindle servo adjustment knob, etc. These components work together to achieve precise processing control and ensure that each processing link can meet high standards of precision requirements.

    4. Daily maintenance of EDM drilling machine

    The maintenance of the EDM drilling machine is also an important part that cannot be ignored.

    a. Before processing, select the appropriate electrode tubes according to the different materials of the workpiece and the requirements of the hole diameter;

    b. Observe the wear of the electrode tube in time during the processing. Once the electrode tube is found to be seriously worn, it should be replaced in time to ensure that the processing accuracy is always maintained at a high level;

    c. The working fluid needs to be replaced and filtered regularly to maintain its cleanliness and cooling effect to avoid adverse effects on processing;

    d. Pay special attention to check the sealing of the working fluid system to prevent leakage;

    e.  The circuits and electrical components inside the machine should be cleaned regularly to prevent dust and dirt from affecting their normal operation;

    f.  Regularly check the lubrication of transmission parts and add or replace lubricating oil in time to ensure smooth operation of the transmission system;

    g. Check the rotating head and high-pressure water pump seals regularly. If they are worn or aged, they should be replaced in time to avoid affecting the normal operation of the equipment;

    h. The lubricating oil of the high-pressure water pump needs to be replaced regularly, generally every three months, to ensure the normal operation of the water pump and extend its service life;

    i. Regularly check whether the fasteners of various parts of the machine tool are loose. If they are loose, tighten them in time to prevent problems such as vibration or displacement during the operation of the machine tool;

    k. For EDM drilling machines that have not been used for a long time, they should be powered on and tested regularly to keep the machine in good condition.

    Through good maintenance, the occurrence rate of failures can be effectively reduced, processing efficiency can be improved, and a more stable and reliable guarantee can be provided for the company's production activities.

    With the continuous advancement of science and technology, modern EDM drilling machines are also constantly introducing new technologies and functions. For example, the automatic electrode tubes replacement device can significantly improve processing speed and efficiency and reduce the time of manual operation. Some high-end models are also equipped with intelligent CNC systems, which can achieve automatic operation and precise control to meet complex processing requirements. These advanced technologies and functions make the position of EDM drilling machines in modern manufacturing more stable and important.

    With its remarkable features of high precision, high efficiency and high stability, the EDM drilling machine has become an indispensable key equipment in the modern manufacturing industry. Whether in precision mold processing, aerospace, automobile manufacturing or other fields, it plays a vital role, providing reliable technical guarantee for precision processing in all walks of life, and promoting the continuous development and innovation of the manufacturing industry.
