Reaming refers to semi-finishing and finishing of existing holes to obtain a process with accurate dimensions, good surface roughness, and good shape error such as roundness and cylindricity.

When reaming with a carbide insert, the diameter of the reamer must be correctly determined in order to machine the precision hole. For this reason, it is necessary to consider the expansion margin determined by the workpiece material and the processing conditions. In addition, in order to obtain a good finished surface and touch the reamer with high precision, the cutting conditions must be correctly selected.

The accuracy of the reamer depends mainly on its diameter and radial runout. Regarding the cutting conditions, from the viewpoint of improving the machining accuracy, it is preferable to select a low-speed cutting of a cemented carbide insert, but it is necessary to consider the upper limit of the processing efficiency.

Carbide reaming tool wear is also a common way of wear of cemented carbide inserts, mainly: flank wear and crater wear, usually after face wear is a natural form of wear, especially for outer blades with higher cutting speeds. Words. However, this wear will eventually result in the cutting edge of the insert not being able to machine the required tolerances and high surface quality. The carbide reaming tool is used for drilling. For safe production, the blade should be replaced in time when the wear to the surface and the wear of the crater exceed a certain value.

Carbide reaming tools work on the premise of safe production is the fundamental to improve production efficiency.
