Definition - What does Reaming mean?
Reaming is a finishing operation that is performed with multi-edge tools which provide high-precision holes. At a high penetration rate and small depth of cuts, a superb hole quality, close dimensional tolerance and high surface finish are achieved. The operation is performed with the help of reamers which are round cutting tools that enlarge the size of existing holes. Reaming should not be considered only as the correction of location and alignment of holes. The primary purpose of the operation is fine tuning the diameter of the holes.
Petropedia explains Reaming
Reaming slightly enlarges the holes that already exist to tightly tolerated diameters with the help of a reamer. Reamers are similar to mill bits which have several cutting edges arranged around the central shaft. The operation can be performed by hand because of its delicate nature and as little material is also removed. This operation is mostly accurate for the axially symmetric parts reamed and produced on a lathe. There are several parameters that can impact the life of the reaming tool such as run-out, offset, cutting depth, coolant, concentration, pressure, speed and feed. The geometric configuration and substrate of reamers differ depending on the material they are proposed to perform reaming on.
