The diamond surface polishing method according to the present invention involves polishing a polished object, the surface of which is made of diamond, by rubbing a polishing member having an elongated shape such as a linear or belt-like shape and containing at least a metal or a metal oxide against the diamond surface, wherein a pressing force of the polishing member is controlled in accordance with material properties of the polishing member and/or a shape of the polished object and a diamond crystal size in a rubbing section so that contact surface pressure in a machining area becomes uniform.

Methods of forming a cutting element include leaching a diamond table of the cutting element and subsequent to leaching the diamond table of the cutting element, forming a chamfer on the diamond table of the cutting element at an interface between a cutting surface of the diamond table and an outer side surface of the diamond table. Methods of forming earth-boring tools include forming a cutting element and securing the cutting element to a body of the earth-boring tool. Forming the cutting element includes including leaching a diamond table of the cutting element and subsequent to leaching the diamond table of the cutting element, forming a chamfer on the diamond table of the cutting element at an interface between a cutting surface of the diamond table and an outer side surface of the diamond table.

There is provided a method and apparatus for processing a diamond surface. The method comprises: i. locating a diamond material having a first surface and a second, opposite surface, in a holder, the holder located at the end of a positioning arm; ii. processing the first surface on a rotating wheel; iii. while the diamond material is in the holder, measuring an angle of the first surface relative to the second surface; iv. repeating steps (ii) and (iii) until a desired angle is achieved.

The present invention provides a jewel grinding system applied to fields of grinding and processing detection. The jewel grinding system includes a base, a placement rack, a loading robot arm, a movable clamping module, a grinding module, a travel monitoring module, a light spot analysis module, and a control module. An angle of a grinding disc can be freely adjusted to meet different grinding requirements. In addition, a designed first transmission mechanism can achieve transmission to the grinding disc that is flexibly adjusted, and the structure is simple and efficient. By providing the travel monitoring module, a grinding effect can be monitored and measured in real time, which is conducive to intelligently adjust operation of the movable clamping module. Therefore, processing of 36 facets at a crown and a girdle can be well achieved, so that a display effect of 9 hearts and 27 arrows is achieved. Symmetric facets can be grinded at the same time by grinding discs that are symmetrically provided, and thus a grinding efficiency and accuracy are improved. A grinding degree of each facet can be visually and intelligently detected by providing the light spot analysis module. Accurate and rapid mounting can be assisted by providing the loading robot arm.
