Methods and apparatuses for forming cutting elements having a chamfered edge for earth-boring tools

摘要

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.

1. An apparatus for forming a chamfer on a cutting element for an earth-boring tool, comprising:
a device configured to temporarily hold and position a cutting element for an earth-boring tool; a first emitter rotatable about a longitudinal axis of the cutting element and configured to emit a beam of energy at a first wavelength and oriented to form a chamfer on an edge of a superabrasive table of the cutting element held and positioned by the device using the beam of energy emitted by the first emitter toward the edge of the superabrasive table of the cutting element, the first emitter being located on a first side of the device configured to temporarily hold and position the cutting element; and an additional emitter rotatable about the longitudinal axis of the cutting element and configured to emit another beam of energy at a second, different wavelength and oriented to polish the chamfer using the another beam of energy emitted by the additional emitter toward the edge of the superabrasive table of the cutting element, the additional emitter being located on a second, opposing side of the device configured to temporarily hold and position the cutting element.
