The Odds Aren’t Stacked Against You.
Our customer, who manufactures baffle plates for the military and defense industry, needed to reach at least 100 IPM (2450 mm/min) while drilling through five plates tack welded together that are each 1/2" (12.7 mm) thick.
With 10,000 holes per stack plate assembly, the customer needed to produce a tight tolerance hole with a 32 Ra finish consistently through all five plates. The competition was running at 95 IPM (2413 mm/min) and only achieving a 63 Ra surface finish.
This customer reached out to Allied for help in achieving the results they needed. Using the cast aluminum (CAB) Superion burnishing drill—developed with a unique point, web, and cutting edge to significantly improve hole finish and tolerance—the customer was able to achieve the desired surface finish and tolerance while running over 100 IPM (2450 mm/min).
In addition to achieved surface finish and penetration results, the Superion drill also dramatically increased the tool life from 2000 holes to 10,000 holes—a 400% increase. With Allied, the odds will never be stacked against you. Call us to help you find the right tool for the job.
