<p>A method of manufacturing a metal bonded abrasive product such as a saw or drill segment or bead for a diamond wire is provided. The method includes the steps of providing a mixture of the metal, in particulate form, and the abrasive particles, cold pressing the mixture to the desired final shape at a pressure in the range 320 to 1500 MPa to produce a cold pressed product at a temperature in the range 900 to 1300 °C under conditions which inhibit degradation of the abrasive particles and the particulate metal. The product, after free sintering, will generally have a relatively high porosity, for example, a porosity of 10 to 25 percent by volume.</p> |
