An exceptional technology ...
is needed in order to manufacture non cylindrical bores in slim workpieces. That becomes possible with a special combined manufacturing method. The BGTB chamber-boring-technology combines the perfected technology and economy of the BTA deep-hole drilling process. For tha we use the precision and the versatility of the modern CNC-technology. The BGTB system consists of three basic components:
- special boring bar
- and CNC drive unit.
It is developed to be used on a modern CNC deep-hole-drilling machine tool. The internal contour can be finished in one setting, starting with e.g. BTA solid drilling process.
