RADIAL TOOL WITH SUPERHARD CUTTING SURFACE |
摘要 |
<p>A non-rotating mining cutter pick (10) has a shank portion (12) with a non-circular cross-section, a head portion (16) including a tip region (28) distal from the shank portion (12), a shoulder portion (14) separating the shank portion (12) from the head portion (16), and a cutting insert (30) mounted at a front end (32) of the tip region (28). The cutting insert (30) includes a body (34) formed of tungsten carbide and an element (36) formed of a superhard material, such as PCD or other material having a prescribed knoop hardness. At least a portion of a first surface (40) of the element (36) is exposed on a cutting surface (38) of the cutting insert (30), which improves wear properties of the mining cutter pick (10). The element (36) is fused to the body (34) of the cutting insert (30), preferably in a high pressure - high temperature (HPHT) process. A method of manufacture and a cutting machine incorporating the non-rotating mining cutter pick on the rotatable element are also disclosed. ??</p> |
