In the horizontal boring machine processing hole diameter 100, deep 350 blind hole how to process
3, after the knife is installed, the main blade, the tip part of the 4 mm and the hole perpendicular to the rest of the 93 ° away from the bottom to prevent the knife boring in the end, the main knife full knife, resulting in vibration and broken knife phenomenon.
1, regardless of the original bottomless hole, the first use Φ50 above flat drill, the hole drilled to the depth.
2, to prepare two, with the oblique hole on the end of the boring bar, a Φ40 it first hole to Φ70 (the original bottom of the hole must pay attention to the bottom of the bottom hole, the bottom of the drill bit with a small bottom hole
With 45 ° oblique boring bar, boring blind hole, boring bar end 45 ° oblique hole loading knife, is conducive to the bottom of the hole at the end of the root, using the following process:
