Axle Weldment: Opening Drill®

Code:

6502

The Challenge

The customer is manufacturing automotive components for a specialty truck manufacturer. They are using a Giddings & Lewis 35 HP Boring Mill with minimal coolant pressure to machine an axle weldment made from 1018 low carbon steel.

Unsatisfied with this process, the customer needed to reduce the number of tools used to complete the operation and also lower their tooling costs.

The Opening Drill® easily achieved the customer’s goals.
