Effect of the Cutting Edge Quality of Reamers on the Surface Roughness of Bores.

Reaming, which is often the last operation in boring, makes it usually possible to achieve an accurate geometric shape and dimensional stability of the bores, as well as high quality-machined surfaces. Compared with other machining processes, reaming has the advantage that only one tool is necessary to machine a large number of bores and that it can be performed on almost all machine tools with a rotating spindle. The roughness of the machined surfaces is influenced, among other things, by the cutting edge quality of the reamer.
