Solid tool construction for accurate bottle boring results
In addition to the best possible tool accuracy, high process productivity is naturally also required. This needs stable a tool/process for efficient workpiece machining.
In our case, instead of using a tool cutting edge, we inserted a
forming punch into our bottle boring tool and formed this steel tube on a deep hole drilling machine. The forces required for forming are many times higher than in machining.
If the tool cutting edge can handle the machining process, so can our bottle boring tool!
Guide pad quality decisive for the production of demanding inner contours
We are always looking for the best possible bottle boring quality: The
performance of the guide pads is also a decisive factor!
We also want to offer high-quality guide pads for our customers' bottle boring tasks. With an additional intermediate step before coating (see photo) in the guide pads production, we achieve a more wear-resistant guidance of our bottle boring tools. This not only optimises the
dimensional accuracy and
surface quality of the chamber but also guarantees that the good surface of the guide bore is kept.
Since workpieces with chambers are basically already very valuable workpieces, it is our goal to also supply valuable wear parts for our bottle boring tools.

Pull counterboring tools
BGTB Pull Counterboring Tools are used for applications where the new bored diameter must be held closely
concentric to the ID of the tube through-out its entire length. Since the pull boring head follows the existing hole, it is particulary useful in maintaining a
uniform wall thickness in cambered tubing.
The head is constructed with three to five replaceable and individually adjustable indexable inserts, held in a
Cutting Star holder for efficient machining. The
Fore Runner has a series of guide pads that are
hydraulic activated and guarantee the position of the tool in the tube.

What many people certainly don't know is that BGTB has been a manufacturer of interchangeable clamping elements made of carbide for a couple of decades. grip and plat under the old familiar name "heller grip" can easily be purchased here:
Bottel Boring BGTB AK-NC-SB60
BGTB offers its customers different types of bottle boring tools. Today we would like to introduce the most powerful design.
Due to the internal cartridge, which is precisely controlled (via NC-Axis), the tool can handle high mechanical cutting loads. An integrated hydraulic function keeps the tool stable throughout the process, independent of changing cutting forces.
Depending on the material, e.g. AISI4140, cutting depths of 4 - 6 mm (0.16"- 0.23") can be reliably achieved, resulting in a very economical process with the desired surface quality.
Mechatronic Tool System for the Compensation of Straightness Deviation
The aim of the research project is therefore the development and research of a mechatronic tool system for the compensation of the straightness deviation. This carries out the straightness deviation correction without a process interruption and is to be retrofitted for existing deep drilling machines. On the basis of the knowledge gained in the preliminary tests, a special boring bar will then be manufactured, which will enable the drill head to be displaced in a targeted manner. This boring bar is controlled by a mechatronic system. Through a process-parallel recording and analysis of the straightness deviation, continuous tool-side compensations are initiated.
BGTB GmbH is happy to cooperate as a project partner in the development of a mechatronic tool system for the compensation of straightness deviation in BTA deep hole drilling.
