Drilling Technology of Tungsten Carbide Cutting Tool

Tungsten carbide cutting tool drilling process is closely related with subsequent processing, such as sleeve holes, reaming and boring. These same points of tungsten carbide cutting tools for drilling process is rotating the main motion and linear feed movement combined. Sleeve hole is mainly used for large-diameter holes, unlike the entity that consumes a lot of power drilling. Sets of holes drilled across the diameter of the hole is not drilling, but drilling a ring on the circumference of the hole. It is not all materials are removed in the form of chips, but leaving a core around the center, therefore, the main thoroughfare such that the drilling process is the application of the through-hole; reaming tool is dedicated to expand the existing hole, it species around the hole drilling process is cutting out a lot of metal; reaming is already finishing hole. This drilling process will remove a small allowance, so as to achieve better surface quality and small tolerances.
