按图纸要求,需钻削一个与另一个横向精密孔相通的孔,这样,在两个私的交界处去除毛刺往往有一定的难度。对于这种情况,可将一件已磨损的光滑塞规的一端磨削成斜角为45°的凹圆弧面,经实际使用,效果良好。为了获得满意的加工效果,根据具体的加工要求,选择直径尺寸合适的塞规,塞规的直径应比孔径略小0.0025～0.005毫米,磨削成图示的形状。这样,去毛刺时就能方便地插入孔里,轻轻旋转,就可将孔里的毛 According to the requirements of the drawings, a hole drilled in parallel with another transverse precision hole should be drilled. In this way, it is often difficult to remove the burr at the junction of the two private bodies. In this case, one end of a worn smooth plug gauge may be ground into a concave arc with a bevel of 45 °, and the actual use will be effective. In order to obtain satisfactory processing results, according to the specific processing requirements, select the diameter of the plug plugs appropriate size, plug gauge diameter should be slightly smaller than the diameter of 0.0025 to 0.005 mm, ground into the shape shown. In this way, when deburring can be easily inserted into the hole, gently rotating, you can hole the hair
