Sunnen Deep Hole Drilling - Double Tube Drilling

Bottle Boring

Bottle Boring, or internal profiling, is a tooling concept for internal contour boring of components with pre-existing holes. This development was prompted by the industry’s need for internal undercuts and internal contours that are generally too deep or too complicated for single point boring bars.

The bottle boring tool is essentially designed to ID contour bore a specific component. The tools are generally furnished as an assembly and not as an add-on for existing tooling.

Our bottle boring tool assemblies are utilized on deep hole drilling machines equipped with an additional x-axis drive controlled by the machines' CNC programming.

Your Complete Internal Profiling Solution

The bottle boring tool assembly consists of a cutter head that houses a right angle feed-out insert cartridge and indexable insert. This cutter head is threaded to a carrier body that contains guide pads that support the tool in the pre-existing bore component. Which, in turn, is threaded to a drill tube (boring bar). The drill tube houses a push-pull indexing rod that actuates the right angle feed-out cutter in the cutter head by whatever amount the additional x-axis drive is told to move by the machines' CNC control.

Each bottle boring tool assembly can be manufactured to accommodate components with either through or blind holes.
