Composite cutting element containing diamond particles and method for its preparation |
| 摘要 |
<p>The composite cutting body comprises diamond particles (2), whose grain size is smaller than that of the cutting body, embedded in a matrix made mainly of metallic binder (2). Each cutting body (1) is agglomerated in a single moulding process made of a mixture of diamond particles (3) of grain size of >50 mu m and <300 mu m and binder (2) and sintered. The grain size of the composite cutting body (1) is 400-1200 mu m.</p> |
