Abstract
A burr removing device for removing a burr, which is formed at a connection between a first hole and a second hole that are angled relative to each other inside a workpiece. According to the burr removing device, a generated high-density energy beam is converged by a converging lens, which is located outside of the first and second holes of the workpiece. Then, the converged high-density energy beam is reflected toward the burr by a one reflecting mirror, which is located in one of the first and second holes.

A method for removing a burr, which is formed at a connection between a first hole and a second hole that are angled relative to each other inside a workpiece, the method comprising:
- generating a high-density energy beam;
- converging the high-density energy beam by a converging lens, which is located outside of the first and second holes of the workpiece;
- and
- reflecting the converged high-density energy beam toward the burr by at least one reflecting mirror, which is located in one of the first and second holes.
A burr removing device for removing a burr, which is formed at a connection between a first hole and a second hole that are angled relative to each other inside a workpiece, the burr removing device comprising:
- a high-density energy beam generator for generating a high-density energy beam;
- a tubular housing, which is located in one of the first and second holes at time of operation;
- a converging lens located outside of the workpiece for converging the high-density energy beam generated by the high-density energy beam generator;
- and
- at least one reflecting mirror located inside the tubular housing for reflecting the high-density energy beam, which is converged by the converging lens, toward the burr.
