<p>A method of processing a super-hard material product 6, 100 having a Vickers hardness of no less than 2000 kg/mm2 comprises mounting the super-hard material product 6, 100 with a surface in contact with a surface of a processing wheel 2, loading the super-hard material product 6, 100 such that it is pressed against the surface of the processing wheel 2 with a loading force, rotating the processing wheel 2 and feeding an abrasive slurry 14 onto the surface of the processing wheel 2, the abrasive slurry 14 comprising a carrier fluid within which are disposed super-hard abrasive grit particles 104 having an average particle size of at least 1µm, which particles 104 roll between the surface of the processing wheel 2 and the surface of the super-hard material product 6, 100 in order to cause surface micro-cracking of the super-hard material product 6, 100 and removal of material from the surface of the super-hard material product 6, 100, the method further includes at least two processing periods: a first processing period during which the loading force 106 is applied to the super-hard material product 6, 100 in a non-central location of the super-hard material product 6, 100 and a second processing period during which the loading force 106 applied to the super-hard material product 6, 100 is reduced and centralised on the super-hard material product 6, 100 relative to the loading force 106 applied during the first processing period.</p> |
