摘要：A good electric contact device is provided for carrying electrical current to arotating cylindrical part; it comprises

at least one conducting plate mounted around the rotating cylinder to be suppliedwith current, rotating together with it, while establishing a gold, almostfrictionless,electrical contact,

< P>at least one electrical contact which is stationary during the rotation of thecylinder and provided with at least one housing in which means are set which are suppliedwith electricity from a generator, said contact having at least one side intended to beapplied against one of the sides of the conducting guide so as to transmit to it veryefficiently, almost without friction and overheating, the electrical current,and

means to apply the stationary contact against the rotating guide.

These contacts are advantageously used for feeding the electroerosive current to arotating spindle in an E D Milling machining.
