Graphite

Graphite has gained in importance as a raw material particularly in the manufacturing of electrodes.  For tool- and mould construction, graphite electrodes have become indispensable.  Graphite is also used successfully in mechanical engineering and medical engineering.

    Milling graphite

    Graphite differs in both Shore Hardness and granulation. The product range of HUFSCHMIED tools covers a granulation spectrum from 3 µm to 10 µm.  Since the material is very abrasive, all tools for the milling and drilling of graphite should be diamond-coated.  Our tools are suited to both wet- and dry-processing of graphite.

    For small and intricate geometries, HUFSCHMIED offers mini milling cutters from a blade diameter of 0.2 mm in different projection lengths.  The largest diameters of our two- to four-flute tools are at 20 mm. You can also find extra-long tools and other options in our range.

    HUFSCHMIED has developed Time Saving Concepts for the highly efficient machining of graphite.

    • Time Saving Concept 1

      In Time Saving Concept 1, our Graftor tool is deployed – a tool that can be used for both roughing and smoothing.  By using the Graftor tool geometry, the processing time of a graphite electrode can be decreased by up to 50%.

      Furthermore, a multitude of different tools can be replaced by one single tool.  This will save on the number of machine stations at the machine.  Programming effort is also reduced, since a smaller number of tool measurements is necessary for the manufacturing of the electrode.

    • Time Saving Concept 2

      Time Saving Concept 2 has been designed for older machines where two different tools for roughing and smoothing are used: a graphite roughing cutter with WD tooth arrangement and the three-flute Piranha smoothing cutter for high quality surfaces.

      Time Saving Concept 2 can save you up to 30% of your processing time.  The service life of all our tools for graphite machining is significantly increased due to our patented DIP diamond coating.

      For small and intricate geometries, HUFSCHMIED offers mini milling cutters from a blade diameter of 0.2 mm in different projection lengths.
