20110176878 | Drill Head Manufacturing Method and Drill Head - A drill head manufacturing method calls for a cutting tip to be CVD coated, brazed to a distal end of a drill head, polished and then PVD coated. The process effectively utilizes features of a CVD coating, which renders a tool service life longer and enables a drill head more suitable for high-speed cutting to be manufactured. A cutting tip having been CVD coated with a hard material is brazed at a brazing temperature to a predetermined portion at a distal end side of a head main body. An outer diameter portion OD of the brazed tip about a rotation axis of the head main body is polished. Then, the cutting tip and the head main body are PVD coated with a hard material at a second temperature lower than the brazing temperature. | 07-21-2011 |
