BTA Drilling Machines
BTA stands for Boring and Trepanning Association which develop BTA which is a deep hole drilling system. It involves a single drill tube in which high pressure coolant is supplied to the drill through the annular area between the drilled hole and the tube outer diameter. The chips are evacuated through the I.D. of the tube. The drill head is screwed to the offered drill tube which is much stronger as compared to the kidney shaped shank of a gun drill. Hence, much higher metal removal rates are possible. It involves the use of a pressure head, which is basically a high pressure seal between the workpiece and the drill bush. The BTA or STS drilling is generally used for ф19 and above.
BTA Drilling is a drilling process of deep hole in metal having a diameter of 20 mm and more. This has become the most effective and precise method of drilling deep holes. BTA Drilling Machines are widely used to carry out this process as the machines ensure cleaner, reliable and accurate holes than any other conventional twist drills. The machines are ideal to create holes having larger diameters and utmost feed rates. They are available with durable and sturdy heads mounted onto drill tubes with varied cutting surfaces to remove chips professionally. They are available with brazed or carbide inserted tooling configurations.
Features of BTA Drilling Machines:
1) Available with intuitive control technology to ensure maximum process reliability.
2) Modern touch panel to provide important parameters to users.
3) Chip breakage can be individually programmable.
4) No tool wear and abrasion owing to hard-wearing structure.
