EDM drilling machine is an electrical discharge drilling machine that uses electrical discharge technology to drill holes. It can perform precision drilling on hard materials, such as metals, ceramics, glass, etc.

The working principle of EDM drilling machine:

The working principle of EDM drilling machine is to use the principle of electric spark discharge for processing. Specifically, it generates a high-frequency electric spark discharge between the surface of the workpiece and the electrode, so that the material on the surface of the workpiece is melted and evaporated, thereby forming tiny holes.

The electrodes of an EDM drilling machine are usually made of copper or a copper alloy, and they are placed at the desired location on the surface of the workpiece. Then, by controlling the distance between the electrode and the workpiece and the movement trajectory of the electrode, the required holes can be formed on the surface of the workpiece.

The processing precision of EDM drilling machine is very high, which can reach micron level. It is suitable for processing materials of various hardness, including metal, ceramics, glass and so on. At the same time, it can also process holes with complex shapes, such as tapered holes, chamfered holes, etc.

Application fields of EDM drilling machine:

EDM drilling machine is usually used in the manufacture of micro parts, molds, electronic components and precision mechanical parts, and other fields.

Advantages of EDM drilling machine:

High-precision: It can realize high-precision drilling, and the drilling accuracy can reach below 0.01mm.

High efficiency: A large number of drilling tasks can be completed in a short period of time, which improves production efficiency.

High stability: The stability is very high, which can guarantee the quality and precision of drilling.

Wide applicability: EDM drilling machine can drill various materials, including metals, non-metals, hard alloys, etc.

Strong flexibility: Drilling holes of different shapes and sizes can be carried out according to the needs, which is very flexible.

Environmental protection and energy saving: No need to use coolant, no waste water and waste gas, and meet environmental protection requirements.

What are the maintenance methods of EDM drilling machine?

Regular cleaning: Clean the shell, workbench, guide rail, electrode clamp and other components of the EDM drilling machine to prevent dust and debris from entering the machine.

Hydraulic oil replacement: replace the hydraulic oil regularly to ensure the normal operation of the hydraulic system.

Electrode Replacement: Regularly replace the electrode to avoid excessive wear of the electrode and affect the processing quality.

Hardware inspection: Regularly inspect the hardware components of the machine, such as motors, transmissions, electrical components, etc., to ensure their normal operation.

Program backup: regularly back up processing programs to prevent data loss.

Processing fluid replacement: Regularly replace the processing fluid to ensure the cleanliness and stability of the processing fluid.

Check the power supply: Check the power supply line regularly to ensure the safety and stability of the power supply line.

Regular maintenance: Regularly maintain the EDM drilling machine, such as lubrication, adjustment, fastening, etc., to ensure the normal operation and service life of the machine.
