Wire Cutting EDM

It is well known in the metal processing industry that electrical discharge machining (EDM) is also known as spark machining, spark eroding, die sinking, wire burning or wire erosion. This is a manufacturing process that uses sparks that usually generate sparks to obtain the target shape, so it is also called spark machining in Chinese.
 
In the process of wire EDM, a series of fast circulating currents remove excess material from the workpiece. In these components, one electrode is called a tool electrode, and the other electrode is called a workpiece electrode. The machining process is determined by tools and workpieces that will not actually contact.

Wire Cutting

In the EDM category, there are multiple EDM processing methods. In this article, our main theme is the wire cut EDM. Wire cutting machines are a manufacturing process that uses spark-generating discharge to obtain the target shape. In the process of wire cut EDM, a series of rapid operations to remove unwanted materials on the workpiece circulating current as the design process of the machining program. In addition to wire cutting, there is also the ZNC die sinking method, which is a processing method. It is mainly used for hard metals or metals that are difficult to process with traditional techniques. EDM generally uses conductive materials, even though methods for processing insulating ceramics using EDM have also been proposed.
 
EDM can cut complex contours or cavities in pre-hardened steel without heat treatment to soften or re-harden them. This method can be used with any other metal or metal alloy (such as titanium). Due to its extremely small cutting performance, EDM can also be used for micromachining. In common industrial analysis, it has been recognized that the term "micro machining" refers to the process of using tools with a diameter of less than 0.015 inches, and the tolerances also meet certain standards. In order to achieve micro machining, the use of small-diameter tools requires a specific spindle speed, and the machine must be very accurate to a certain extent.
 
In the application of EDM machines, EDM can perform this type of process with very good quality and output as required. There are now many industries that require precision EDM micro machining to achieve tolerances in the micron range. Considering this practical application, the establishment of a micro-machining center can meet these requirements of machine and engineering services. The development of EDM is still in progress, and hope to further improve the entire process to cope with the processing process. This is a more effective way to bring higher productivity to business owners.

 

Wire Cutting EDM Applications

EDM is a very common metal cutting technology in industry today. With this technology, people can process hard and complex materials. It is the most widely used in mold-making, tool making, and die-making industries. Now, it has become a conventional method for prototypes and production parts for pioneering projects, especially in the aerospace, automotive, and electronics industries.
 
Some people may think that the entire EDM processing is limited to the work area, so the workpiece may not be allowed to be too large. However, because EDM has great flexibility, there are larger models of EDM that can use larger types of EDM machines. In the drilling EDM category, small hole EDM is used for a variety of applications.
 
Conventionally, on a wire cutting machine, a small hole drilling EDM is used to make a through hole in a workpiece, and a wire used for wire cutting EDM operation passes through the through hole. A separate EDM head designed for small hole drilling will be installed on the wire cutter and allow large hardened plates to eroded finished parts from it as needed.
 
Small hole EDM is used to drill rows of holes in the leading and trailing edges of the turbine blades of jet engines, thereby providing the industry with high-precision machining quality. The airflow through these small holes will allow the engine to use a higher temperature than other ways.
 
Expectations from the Industry
Expectations for EDM improvement vary by industry, and ultimately all processing conditions are different, so the expected results are also different. Its goal is to become smarter. Because the trend requires all metal processing machinery to be used, the next generation of products will be integrated with more of this concept.
