The Challenge

A customer manufactures ball screws, aerospace actuators, and landing gear actuators for the aerospace industry. In this application, they are using an Okuma VMC with 750 PSI (51.711 bar) through-tool coolant to machine a gear actuator housing made from cast stainless steel.

Unsatisfied with their current process, the customer needed to increase tool life and reduce the cost of production.

The Original T-A drill achieved the customer’s goals by increasing tool life while lowering the overall cost of production.
