The BGTB-chamber boring technology, combines the sophisticated technology and efficiency of BTA deep hole drilling with the precision and versatility of modern CNC technology. The BGTB system is designed for use on modern CNC deep hole drilling or turning machines. The inner contour can , for example, starting with the solid drilling process be completed in a single set.
e.g. by BTA solid drilling process.
is decisive for the chamber quality.
A pulling process. With cut division: made in short chamber technology,
by removing the cutting edge and the tool out of the workpiece.
The BGTB chamber boring system in the standard version is fundamentally able to work with stationary and rotating tools
Different tools in the diameter range from 45mm to 90mm. Optimization of guiding by hydraulically actuated carbide guide pads.
Boring bars with different diameters. Boring bar ends with coupling piece for hydraulic and control rod.
The drive of the chamber boring tools is conceived as a control unit for deep hole drilling and turning machines (complete machining).
To reduce weight or to implement specific functions the internal profiling is necessary.
Aircraft landing gear parts are typical internal profiling parts.
An essential requirement of these components combine maximum strength with minimum weight.
They are usually very complex components.
Turbine shafts are lightweight, thin-walled parts and usually of highly heat resisting materials.
These parts almost always have complex internal profiles often with chamber recesses.
Also by the used workpiece material, they are difficult to machine.
Extruder barrel with two intersecting, non axially parallel , tapered bores.
The bores are made in succession with chamber boring tools. There is a drilling task with extremely small tolerances.
Look into an extruder barrel.
