The Challenge

The customer is machining A36 mold backing plates using a DOOSAN DB 130CX Horizontal Boring Mill with 200 PSI (13.79 bar) through tool coolant.

Competing with off-shore mold makers, the customer was looking for a way to speed up this job. Allied was asked if they had a solution.

The difference was amazing as Allied was able to reduce the operation time from hours to just minutes. Completion of 6 holes using Revolution Drill® took less than 3 minutes, while the Opening Drill® opened 3 holes from 2” (50.8 mm) to 3.6” (91.44 mm) in under 2 minutes, outperforming the competitive tooling by over 4 hours!
