Abstract:
Apparatuses for forming chamfers on superabrasive tables of cutting elements for earth-boring tools include a chuck for temporarily holding and positioning a cutting element, and at least one emitter for emitting a beam of energy toward an edge of a superabrasive table of a cutting element held and positioned by the chuck. Methods of forming cutting elements for earth-boring tools and methods for forming earth-boring tools are also disclosed.
