Landing Gear: BT-A
Code
0901
The Challenge
The customer is machining aerospace landing gear made from 4340 alloy steel using a LeBlond Heavy Duty Lathe with 60 GPM (227 LPM) of oil.
The customer needed to improve the process and reduce cost. They asked Allied for a durable solution at a lower price.
The BT-A Drill completed 43 pieces against Sandvik’s disappointing 2 pieces. The BT-A Drill cost was justified after only 15 parts.
