Other finishing tools

Fabrication and finishing tools are numerous and show a great variety. This reflects the diversity found in the application itself. Although very different in their finality, the fabrication of a kitchen top and the sculpting of a 3 meter-tall statue share the fact that they are the last step in processing of the stone. But needs can differ greatly whether you shape your block of stone with a hand-held grinder, when you cut a bowl opening with a semi-automatic radial arm machine or you shape and polish the edge of a vanity top on an automatic line. To respond to this great variety and to adapt to the growth of this market, Diamant Boart has widened its corresponding range and has given a greater visibility to it.

Stone surfacing is the whole range of operations which, after sawing or milling, give the surface its final polish. They take place as follows :

  • roughing (or dressing) which effaces the flaws caused by sawing
  • smoothing, which eliminates the scratches left by the abrasive during the previous operation
  • polishing, which gives the stone sufficient finish to take the final glazing
  • glazing, the final operation using a flat plate, in which the diamond plays no part
  • The development of new bonds and impregnations has had the effect of extending the use of the diamond tool to stages subsequent to surfacing, i.e. smoothing and polishing. This development is linked to the advantages which the diamond shows over silicon carbide. They are :

  • to reduce the time and the necessary stages to obtain a finished product
  • to reduce tool replacements due to a longer tool life
  • to avoid inconveniences of silicon carbide tools where loose grains earlier released tend to scratch a surface already treated with finer grit size
