Ways and methods of improving the machining accuracy of EDM machines

ZhangRay

There are many ways and methods to improve the machining accuracy of electrical discharge machining (EDM) machines. Here are a few of the more influential ones. Reduce the vibration of molybdenum wire The vibration sources of molybdenum wire include commutation vibration of the wire storage drum, vibration of the guide wheel (including radial runout...

Factors that affect wire cut EDM machining accuracy

ZhangRay

There are many factors that affect the machining accuracy of wire cut machine tools, such as process (programming skills, cutting path, etc.), machining environment, workpiece material and whatnot, which can influence machining accuracy. The quality of the machine tool itself is an important factor. Accuracy of machine tool movement According to the standard of...

Principles and features of wire cut EDM machines

ZhangRay

Nowadays, wire cut EDM machines are used more and more widely. Do you know their working principle and characteristics? Principles of wire cut EDM machining The principle of wire cut EDM machine is to use tools to connect molybdenum wire with the workpiece to insert a pulsed power source. The molybdenum wire is inserted...

Materials and other factors caused Molybdenum wire breakage

ZhangRay

In addition, there are many other reasons that can cause molybdenum wire breakage, such as differences in materials and other factors. Relating to the materials It is generally considered that it is fragile and easily to break if the metal has not been forged, quenched or tempered. This is due to the uneven distribution...

Pulse power and working fluid caused moly wire breakage

ZhangRay

Pulse power, wire feeding device, and working fluid are all possible causes of molybdenum wire breakage, as detailed in the following analysis. Relating to the pulse power The machining current is very large, and the spark discharge is abnormal, resulting in molybdenum wire breakage. This kind of failure is mostly caused by the output...

One factor causing molybdenum wire breakage- working piece

ZhangRay

There are many reasons for wire breakage in wire EDM. This article discusses one of the factors and its solution. Relating to the working piece The molybdenum wire breaks when the machine processes thin workpieces. Thin workpieces usually refer to the thickness below 3mm. The main reason for the broken molybdenum wire is that...

One factor causing molybdenum wire breakage- electrode wires

ZhangRay

There are many reasons for wire breakage in wire EDM, among which the quality and selection of the electrode wire are very important factors. Relating to the electrode wires Wire tension and cutting speed may affect the result of finish surface of workpieces. For high speed wire cut EDM machining, molybdenum wire of 0.06mm...
