The Challenge

A customer is manufacturing large bearings for turrets on military humvees made out of aluminum. They are using a vertical Makino to manufacture their products.

Also, the customer was using a high speed steel reamer in their production process. Because it was taking the customer one hour to ream the hole, they needed to update their tooling. They also wanted to have a longer tool life.

The ASC 320 successfully eliminated the reaming process in this application.
