摘要
An apparatus and method for adapting a CNC milling machineCMC milling machine (23) for electroerosion machining. The apparatus includes a tubular electrode on the distal enddistal end (22) of an adapter shaftadapter shaft (80). A tool holdertool holder (84) on the proximal end of the adapter shaftadapter shaft (80) is mountable in the chuck of a cutter spindle spindle (24) in the milling machine. The adapter shaftadapter shaft (80) is rotatably mounted within a bearing bearing (98) and an electrical brush contact subassembly, both of which are supported by a bracketbracket (99). The bracket bracket (99) is attached to the milling machine but insulates it from the tool electrodetool electrode (21). The bearing bearing (98) supports the adapter shaftadapter shaft (80) in alignment with the CNC spindleCNC spindle (24). An electrical power supplypower supply (44) energizes the electrode and the workpiece workpiece (28) for electroerosion in a gap gap (74) between them. Electrolyte Electrolyte is circulated through the spinning tool electrodespinning tool electrode (21) during operation. The CNC computerCNC computer (36) is configured to operate the machine, power supplypower supply (44), and electrolyte electrolyte flow for electroerosion machining.
