EDM machine is a commonly used metal processing equipment, which is widely used in mold manufacturing, auto parts processing and other fields. It uses electric spark discharge to generate high-temperature plasma in the gap between the electrode and the workpiece, so as to realize the cutting of metal materials. However, the service life of the EDM machine is affected by many factors, which will be described in detail below.

First of all, the service life of the EDM machine is closely related to its structure and quality. The electric discharge machine is composed of electrodes, electrode clamping devices, workbenches, working fluids, etc. If the structural design of the EDM machine is unreasonable or the manufacturing quality is not good enough, it will affect its service life. For example, if the design of the electrode holding device is unstable, it will easily lead to loosening or deviation of the electrode, thus affecting the machining accuracy and life. Therefore, the manufacturer should pay attention to the rationality of the structure and the reliability of the quality when designing and manufacturing.

Secondly, the service life of the EDM machine is related to the technical level and operating specifications of the operator. The EDM machine is a high-precision equipment, and the operator needs to have a certain technical level and operating experience. If the operator is not familiar with the operation or the operation specification is unreasonable, it will easily lead to equipment failure and damage. Therefore, the training and management of operators should be strengthened to improve their technical level and operating specifications.

Again, the service life of the EDM machine is related to the working environment and working conditions. EDM machines usually need to be operated in a specific working environment, such as temperature, humidity, dust, etc. If the working environment is harsh or the working conditions are unreasonable, it will have an adverse effect on the service life of the EDM machine. For example, a high-temperature environment can easily lead to aging and damage of electronic components, excessive humidity can easily cause electrical components to short-circuit, and excessive dust can easily cause mechanical components to wear out. Therefore, the working environment and working conditions should be reasonably selected to ensure the normal operation of the equipment.

Finally, the service life of the EDM machine is related to maintenance. EDM machine is a kind of high-precision equipment, which requires regular maintenance to ensure its normal operation and prolong its service life. Maintenance includes cleaning, lubrication, fastening, replacement of worn parts, etc. If maintenance is neglected, it will easily lead to equipment failure and damage, which will affect the service life. Therefore, a scientific maintenance plan should be formulated, and maintenance work should be carried out according to the plan.

To sum up, the factors that affect the service life of EDM mainly include structure and quality, technical level and operating specifications of operators, working environment and working conditions, and maintenance. When using, we should pay attention to these factors and take corresponding measures to prolong the service life of the EDM machine and improve production efficiency and economic benefits.
