The Challenge

The customer manufactures blade rings made from 410 Stainless Steel for the power generation industry. They are using a horizontal machining center with flood coolant.

Unsatisfied with this process, the customer asked Allied Machine for a solution to reduce cycle time and decrease the overall production cost.

The Revolution Drill® significantly decreased production time by eliminating the two additional boring passes.
