Machinery users know about EDM processing mostly due to the wire features that is so distinguished from other metal cutting machineries in the market, but there are still some other methods in the EDM family that exploit not wire but other means. One of it is the die sinking EDM method.
About its history, let’s go back early when two Russian scientists were tasked before the end of World War Two in the era of the 1940s to investigate the methods of preventing the erosion of tungsten electrical contacts due to sparking effects. Although the two pioneering scientists failed in this task, their efforts contributed to the technology significantly. They did found that the erosion was more precisely controlled if the electrodes were under some specific circumstances and this inspired a lot to the following experiments. Such inspiring knowledge led them to invent the EDM machine used for processing and machining hard materials such as tungsten and other hard objects.

As one of the critical components of modern machine tools, spindles are designed in a wide variety of forms which is basically based on the driving mechanisms as well as other power systems.
In modern machine tool industry, a spindle is a rotational axis of the machine, which usually designed with a shaft at its center. The shaft itself is named a spindle, but also, in the market slang, the referring term (phrase) is often used metonymically to point at the entire rotating unit, including not only the shaft itself, but also its bearings and anything around (or attached to) to it (such as chuck, cylinder, etc.).Feb 18, 2019
