The Challenge

The customer is manufacturing bearing housings for the renewable energy industry. The housings are made of A516 (grade 70, 23 Rc) using a 40 HP Shibaura BTD- 11ER16 with approximately 120 PSI (8 Bar) and utilizing semi-synthetic coolant. The holes need to be 1.375” (34.925 mm) in diameter, drilled into a 20” (508 mm) thick solid bearing housing.

The customer knew Allied Machine was a leading drill manufacturer with the widest breadth of “off the shelf” products and could handle a job of this hole depth. The customer needed good chip control, good finish, and absolutely no catastrophic failures.

Allied Machine was able to produce good chips with no catastrophic failures. The customer was pleased and utilized the T-A GEN2 with HE geometry for the remainder of the application.
