    26/01/2017· The combination of high feed rate, small-diameter cutting tools, and difficult-to-cut graphite requires milling machine spindle speeds of 20,000 to 40,000 RPM for optimal performance. Milling machines specifically designed for graphite electrode manufacturing are designed with several key differences from typical machining centres, including higher spindle speeds, dust containment and

  • Machining Graphite Keys to Success

    The following is a list of five key concepts to keep in mind when attempting to successfully machine synthetic graphite. First, synthetic graphite should be machined dry without the use of liquid coolants. The use of coolants when working with graphite will produce an abrasive slurry when the coolant combines with the fine bits of graphite chips and dust. The coolant fluid will also permeate

  • Tips for machining Graphite Canadian PlasticsCanadian

    WHAT CHARACTERISTIC SHOULD A CUTTER POSSES TO MACHINE GRAPHITE? One of the key properties of graphite is its brittle nature. The material is soft, abrasive, and brittle. Because of this, using the wrong cutter, feed or speed can result in chipping and breakout. Both chipping and breakout, depending on the grade of graphite, can cause serious trouble to the electrode fabricator. Small ribs
