Abstract
A method for manufacturing drill bit inserts in which the inserts are finished in a centrifugal disc finishing machine. The centrifugal disc finishing machine comprises a configured surface rotating relative to a stationary receptacle, and the inserts may be finished with a mass of materials comprising at least one of a group of media, parts, detergent, and solution. Also, a method of increasing drill bit insert performance comprising accelerating a plurality of inserts in a high-energy finishing machine, wherein the acceleration results in a generally toroidal interaction between the inserts and at least one of the group comprising media, parts, detergent, and solution.
Claims33
A method to manufacture drill bit inserts comprising:
- finishing the inserts in a centrifugal disc finishing machine;
- wherein the centrifugal disc finishing machine comprises a configured surface rotating relative to a stationary receptacle.
A method to increase drill bit insert performance, comprising:
- accelerating a plurality of inserts in a high-energy finishing machine;
- wherein the acceleration results in a generally toroidal interaction between the inserts and at least one of the group comprising media, parts, detergent, and solution.
A drill bit insert finished in a process comprising:
- finishing the inserts in a centrifugal disc finishing machine;
- wherein the centrifugal disc finishing machine comprises a surface configured to rotate relative to a stationary receptacle.
A high-energy finishing device comprising:
- a centrifugal disc finishing machine comprising a configured surface and a stationary receptacle;
- and
- a plurality of cutting inserts;
- wherein the configured surface rotates relative to the stationary receptacle;
- and
- wherein high-speed rotation of the configured surface relative to the stationary surface results in a toroidal motion of the plurality of inserts.
