Abstract

드릴은 칼날에 이어지는 도주면을 평면에 가까운 곡면 형상으로 하고, 중심두께 부분 선단에 상기 칼날에 연속한 칼날을 형성한 것이다.The drill has a curved surface near the plane of the running surface following the blade, and forms a continuous blade on the blade at the tip of the central thickness portion.

연마 장치는 드릴에 대해서 소정 각도로 경사시킨 연마면으로서 회전하는 숫돌에 대해 드릴을 보유한 스핀들을 이 연마면과 평행한 방향으로 왕복하는 수평 운동과, 숫돌의 회전축에 대해서 직교하는 방향으로 전후 이동하는 전후운동과, 이 스핀들에 보유된 드릴을 회전시키는 회전 운동을 동기시키면서 연마하도록 한 것이다.The polishing apparatus is a polishing surface inclined at a predetermined angle with respect to the drill, and the horizontal movement of reciprocating the spindle holding the drill with respect to the rotating grindstone in a direction parallel to the polishing surface and in the direction orthogonal to the rotation axis of the grindstone Polishing is performed while synchronizing the back and forth movement and the rotational movement of rotating the drill held in the spindle.
