BTA - System
The BTA-System is a deep hole drilling system for special deep hole drilling machines and transfer lines with an external coolant supply and an internal chip removal (single tube system). Necessary for suppling the coolant to the workpiece and for sealing off the process on workpiece and boring bar, requires the BTA-System a pressure head (BOZA).
This system is used for bore hole diameters between 7,76 mm and 700 mm and enables hole depths over 100 x D. As from dia. 18 mm the tools mainly become indexable cutting inserts and guide pads.
