The customer manufactures aerospace gears made from 4340 (28 Rc) using a Mazak Lathe with oil-based water soluble coolant.
The customer realized this process was not optimal, and they contacted Allied for a solution.
The Opening Drill® paid for itself after only 60 parts. The customer also makes a number of aerospace gears from of 15-5 stainless and 4340 (ranging from 1.00” ID to 4.50” ID (25.4 mm to 114.3 mm)), and they plan to utilize the Opening Drill in these additional applications.
