Single bit reamer with improved guide members |
摘要 |
The operating life of the two guide members in a single bit reamer is increased by shaping the peripheral surface of the guide members with a radius of curvature less than the radius of the bore being machined. Contact between each guide member and the bore wall takes place only along a central quest area extending in the lengthwise direction of each guide member. This allows coating of the peripheral surfaces of the guide members with a hard, wear resistant material. Further, the guide members may be fastened to the cutter head by means of a screw situated in a groove extending in the tangential direction along the peripheral surface of each guide member. This increases the lubricating and cooling effect.
