The development of modern manufacturing technology presents two major trends, one is the automation technology of modern manufacturing systems; the other is to seek the inherent micro-machining limits of intrinsic manufacturing technology. In micro-mechanics, especially key components such as sensitive devices, control instruments, power systems, and actuators, a large number of micro-manufacturing technologies, such as micro-robots, micro-tools, and micro-aircraft, are used. The demand for these micromachines poses new challenges to modern manufacturing technology. There are two main ways to solve this manufacturing problem, one is the use of MEMS technology, and the other is the use of micro-special processing technology.

From the development and application of micro-machining technology in the world, countries such as Europe and the United States tend to make silicon microstructures, that is, micro-electro-mechanical fields; while Japan pays more attention to processing from macro-size parts by traditional processing methods and special processing methods. Approaching micro-scale parts (such as tiny gears, tiny molds, micro-axes, holes, etc.).

The small parts have small size and low rigidity, and are difficult to process by conventional processing methods. However, in the electric discharge machining, the macro force of the electrode and the workpiece is relatively small, and if equipped with a precise servo feed mechanism, EDM Will be very suitable for micro processing. Micro-EDM technology can ensure the processing accuracy of parts and has high processing efficiency, which is unmatched by other traditional processing methods. In order to further improve the machining accuracy of parts, precision multi-function micro EDM machines similar to machining centers are favored.

In this machine tool, the micro-electrode is processed from the micro-electrode, and the electrode only needs to be clamped once, thus reducing the error caused by multiple clamping electrodes, and can be corrected by reworking the counter electrode. The shape of the electrode is lost, thereby improving the machining accuracy of the part.

On this multi-function EDM machine, it can realize the functions of WEDM grinding, EDM complex shape micro-hole machining and EDM milling, and it is expected to realize micro-EDM three-dimensional machining.

Due to the macroscopic cutting force in the traditional machining process, when machining small parts, especially micron-sized parts, problems such as deformation and heat generation are easy to occur, and precision control is difficult. In addition, the surface is prone to stress and affects the use of the product. performance. Special processing methods use a variety of physical, chemical energy and various physical and chemical effects to directly remove or add materials to achieve the purpose of processing. Special processing methods are mostly non-contact processing, generally do not have macroscopic cutting force effects, so they have irreplaceable advantages in the processing of micro-scale parts.

Metal processing online tips: As a practical micro-special processing technology, micro-EDM has the characteristics of simple equipment and strong implementability. It has shown considerable size in the production of micro-axis, hole processing and micro-three-dimensional structure. The development potential is receiving widespread attention from scholars from all over the world.
