Revolution Drill® 316 Stainless Steel Heavy Machine
 
The end-user is machining pipe flanges made from 316 Stainless Steel using a Toshiba Horizontal Boring Mill, with 600 PSI water soluble through tool coolant.
Previously the customer was using a YG-1 spade drill running at the following parameters: 100 RPM, 0.010 IPR, (0,25 mm/rev) which resulted in 1.0 IPM (25,4 mm/min). The tool drilled a 1.875" (47,63 mm) diameter thru hole to a depth of 4.0" (101,6 mm). The tool had a cycle time of 4 minutes and a tool life of 10 holes. Looking for a reduction in cycle time, the customer asked if Allied could provide a solution.
 
AMEC's Solution
Allied recommended the Revolution Drill using insert item OP-05T308-H and holder R34X22-150L. The tooling ran at a speed of 1000 RPM, 0.004 IPR (0,10 mm/rev) which resulted in 4.0 IPM (101,6 mm/min). The tool had a cycle time of 1 minute and a tool life of 144 holes. The outcome met the customer’s goals of reduction in cycle time.
 
Benefit
Allied Machine made a significant difference for the customer. Revolution Drill helped to reduce the costly cycle time resulting in the cost per hole dropping from $13.59 to $2.58, for a considerable cost savings of 81%, while increasing tool life by nearly 15 times!
