What's the result of the reaming of the inside hole of the reamer?
1, the reason may be the drill spindle and the workpiece hole is not concentric.2. A rotary tool with one or more cutter teeth for removing thin metal on the surface of machined holes, a rotary finishing tool with straight or spiral edges, used for reaming or repairing holes. A rotary tool with one or more cutter teeth used to remove the thin metal layer of the machined surface. After the cutter processing after the hole can obtain the exact size and shape. Reamer for reaming workpieces have been drilling (or hole) after machining holes, mainly in order to improve the machining precision of hole, reducing the surface roughness, tool is used for finishing and semi finishing machining of holes, generally small machining allowance.
The prefabricated hole too, the outer circle of the elliptical reamer reamer, do well. There is a problem with the accuracy of machine tools. Do not understand, we drill bit drill did not appear elliptical hole Oh.
You are using manual reaming Reaming, or drilling reaming? General artificial hand reaming, as long as the hands evenly twisted out of holes is not elliptic, if two handed force is not uniform, then wring out the hole could be elliptical; if you are using drilling reaming, drilling machine main shaft the hole is not concentric with the workpiece, the reamer reaming when leans to one side with Jin twisted down hole was wrung may be ellipse.
