I'd like to hear peoples solutions to graphite electrode machining. We currently use one of our Takuumi CNC machines to machine our electrodes both copper and graphite and I am worried about the longterm damage to the machine and the graphite that gets in to the coolant plugs the filters very quickly. We need a low cost solution to machining these electrodes though as is is not a fulltime usage of the machine. Does anyone know of small machines with vacuum attachments or some other solution?
