<p>An abrasive tool such as a grinding wheel or a saw is characterised by the working portion comprising a mass of ultra-hard abrasive particles dispersed in a non-porous thermoplastic polymer matrix. Examples of suitable thermoplastic polymers are polyetheretherketone, polyaryletherketone, poly(amide-imide), polyphenylene sulphide, liquid crystal polymer and mixtures thereof.</p> |
