I'm working on creating some prototypes for an electrode that is used in radio-frequency spine surgery. The tip of the tungsten wire must be rounded out and I have used just about everything I can find to try and grind a smooth finish to these tips with no luck. If some one could direct me to the proper tool for this, I would much appreciate it. My company is not opposed to spending money for necessary tools, so cost is not so much an option.
