Drilling with the Heller BTA Deep Hole Machining System, or any other single tube system, requires the use of a highly pressurized coolant fluid. This is accomplished with a BTA Oil Pressure Head whose purpose is to:
Introduce coolant to the tool and direct the coolant around the outside of the boring bar
Create a containment seal for the workpiece and the boring bar O.D.
Act as a tool guide
American Heller offers several different configurations of BTA Oil Pressure Heads which are specifically designed to suit the customerís job shop or production applications. They are:
Model 330 series - pressure head-supported rotating workpiece with a live center & rotating guide bushing
