Tool adapter assembly and machining system

A machining system for electromachining of a workpiece, the machining system comprising:

• a machining tool comprising a spindle;
• one or more electrodes configured to perform the electromachining;
• one or more tool holding elements configured to conductively hold the respective one or more electrodes and be assembled onto the spindle of the machining tool;
• one or more adapters comprising one or more bases detachably assembled onto the spindle and an arm having a first end pivotally connected to the one or more bases and a second end opposite to the first end having one or more electrically conductive elements configured to conductively contact the respective one or more tool holding elements;
• one or more power sources electrically connected to the respective one or more adapters and the workpiece so as to energize the workpiece and the respective one or more electrodes to opposite electrical polarities;
• and
• one or more machining solution sources provided to pass one or more machining solutions between the workpiece and the respective one or more electrodes.
